Introduction + + The Opus codec is a real-time interactive audio codec designed to + meet the requirements described in [REQUIREMENTS]. It is composed of + a layer based on Linear Prediction (LP) [LPC] and a layer based on + the Modified Discrete Cosine Transform (MDCT) [MDCT]. The main idea + behind using two layers is as follows: in speech, linear prediction + techniques (such as Code-Excited Linear Prediction, or CELP) code low + frequencies more efficiently than transform (e.g., MDCT) domain + techniques, while the situation is reversed for music and higher + speech frequencies. Thus, a codec with both layers available can + operate over a wider range than either one alone and can achieve + better quality by combining them than by using either one + individually. + + The primary normative part of this specification is provided by the + source code in Appendix A. Only the decoder portion of this software + is normative, though a significant amount of code is shared by both + the encoder and decoder. Section 6 provides a decoder conformance + test. The decoder contains a great deal of integer and fixed-point + arithmetic that needs to be performed exactly, including all rounding + considerations, so any useful specification requires domain-specific + symbolic language to adequately define these operations. + Additionally, any conflict between the symbolic representation and + the included reference implementation must be resolved. For the + practical reasons of compatibility and testability, it would be + advantageous to give the reference implementation priority in any + disagreement. The C language is also one of the most widely + understood, human-readable symbolic representations for machine + behavior. For these reasons, this RFC uses the reference + implementation as the sole symbolic representation of the codec. + + While the symbolic representation is unambiguous and complete, it is + not always the easiest way to understand the codec's operation. For + this reason, this document also describes significant parts of the + codec in prose and takes the opportunity to explain the rationale + behind many of the more surprising elements of the design. These + descriptions are intended to be accurate and informative, but the + limitations of common English sometimes result in ambiguity, so it is + expected that the reader will always read them alongside the symbolic + representation. Numerous references to the implementation are + provided for this purpose. The descriptions sometimes differ from + the reference in ordering or through mathematical simplification + wherever such deviation makes an explanation easier to understand. + For example, the right shift and left shift operations in the + reference implementation are often described using division and + + + + + +Valin, et al. Standards Track [Page 5] + +RFC 6716 Interactive Audio Codec September 2012 + + + multiplication in the text. In general, the text is focused on the + "what" and "why" while the symbolic representation most clearly + provides the "how". + +1.1. Notation and Conventions + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in RFC 2119 [RFC2119]. + + Various operations in the codec require bit-exact fixed-point + behavior, even when writing a floating point implementation. The + notation "Q", where n is an integer, denotes the number of binary + digits to the right of the decimal point in a fixed-point number. + For example, a signed Q14 value in a 16-bit word can represent values + from -2.0 to 1.99993896484375, inclusive. This notation is for + informational purposes only. Arithmetic, when described, always + operates on the underlying integer. For example, the text will + explicitly indicate any shifts required after a multiplication. + + Expressions, where included in the text, follow C operator rules and + precedence, with the exception that the syntax "x**y" indicates x + raised to the power y. The text also makes use of the following + functions. + +1.1.1. min(x,y) + + The smallest of two values x and y. + +1.1.2. max(x,y) + + The largest of two values x and y. + +1.1.3. clamp(lo,x,hi) + + clamp(lo,x,hi) = max(lo,min(x,hi)) + + With this definition, if lo > hi, then lo is returned. + +1.1.4. sign(x) + + The sign of x, i.e., + + ( -1, x < 0 + sign(x) = < 0, x == 0 + ( 1, x > 0 + + + + + +Valin, et al.

Standards Track [Page 7] + +RFC 6716 Interactive Audio Codec September 2012 + + + o ilog(7) = 3 + +2. Opus Codec Overview + + The Opus codec scales from 6 kbit/s narrowband mono speech to + 510 kbit/s fullband stereo music, with algorithmic delays ranging + from 5 ms to 65.2 ms. At any given time, either the LP layer, the + MDCT layer, or both, may be active. It can seamlessly switch between + all of its various operating modes, giving it a great deal of + flexibility to adapt to varying content and network conditions + without renegotiating the current session. The codec allows input + and output of various audio bandwidths, defined as follows: + + +----------------------+-----------------+-------------------------+ + | Abbreviation | Audio Bandwidth | Sample Rate (Effective) | + +----------------------+-----------------+-------------------------+ + | NB (narrowband) | 4 kHz | 8 kHz | + | | | | + | MB (medium-band) | 6 kHz | 12 kHz | + | | | | + | WB (wideband) | 8 kHz | 16 kHz | + | | | | + | SWB (super-wideband) | 12 kHz | 24 kHz | + | | | | + | FB (fullband) | 20 kHz (*) | 48 kHz | + +----------------------+-----------------+-------------------------+ + + Table 1 + + (*) Although the sampling theorem allows a bandwidth as large as half + the sampling rate, Opus never codes audio above 20 kHz, as that is + the generally accepted upper limit of human hearing. + + Opus defines super-wideband (SWB) with an effective sample rate of + 24 kHz, unlike some other audio coding standards that use 32 kHz. + This was chosen for a number of reasons. The band layout in the MDCT + layer naturally allows skipping coefficients for frequencies over + 12 kHz, but does not allow cleanly dropping just those frequencies + over 16 kHz. A sample rate of 24 kHz also makes resampling in the + MDCT layer easier, as 24 evenly divides 48, and when 24 kHz is + sufficient, it can save computation in other processing, such as + Acoustic Echo Cancellation (AEC). Experimental changes to the band + layout to allow a 16 kHz cutoff (32 kHz effective sample rate) showed + potential quality degradations at other sample rates, and, at typical + bitrates, the number of bits saved by using such a cutoff instead of + coding in fullband (FB) mode is very small. Therefore, if an + application wishes to process a signal sampled at 32 kHz, it should + just use FB. + + + +Valin, et al. Standards Track [Page 8] + +RFC 6716 Interactive Audio Codec September 2012 + + + The LP layer is based on the SILK codec [SILK]. It supports NB, MB, + or WB audio and frame sizes from 10 ms to 60 ms, and requires an + additional 5 ms look-ahead for noise shaping estimation. A small + additional delay (up to 1.5 ms) may be required for sampling rate + conversion. Like Vorbis [VORBIS-WEBSITE] and many other modern + codecs, SILK is inherently designed for variable bitrate (VBR) + coding, though the encoder can also produce constant bitrate (CBR) + streams. The version of SILK used in Opus is substantially modified + from, and not compatible with, the stand-alone SILK codec previously + deployed by Skype. This document does not serve to define that + format, but those interested in the original SILK codec should see + [SILK] instead. + + The MDCT layer is based on the Constrained-Energy Lapped Transform + (CELT) codec [CELT]. It supports NB, WB, SWB, or FB audio and frame + sizes from 2.5 ms to 20 ms, and requires an additional 2.5 ms look- + ahead due to the overlapping MDCT windows. The CELT codec is + inherently designed for CBR coding, but unlike many CBR codecs, it is + not limited to a set of predetermined rates. It internally allocates + bits to exactly fill any given target budget, and an encoder can + produce a VBR stream by varying the target on a per-frame basis. The + MDCT layer is not used for speech when the audio bandwidth is WB or + less, as it is not useful there. On the other hand, non-speech + signals are not always adequately coded using linear prediction. + Therefore, the MDCT layer should be used for music signals. + + A "Hybrid" mode allows the use of both layers simultaneously with a + frame size of 10 or 20 ms and an SWB or FB audio bandwidth. The LP + layer codes the low frequencies by resampling the signal down to WB. + The MDCT layer follows, coding the high frequency portion of the + signal. The cutoff between the two lies at 8 kHz, the maximum WB + audio bandwidth. In the MDCT layer, all bands below 8 kHz are + discarded, so there is no coding redundancy between the two layers. + + The sample rate (in contrast to the actual audio bandwidth) can be + chosen independently on the encoder and decoder side, e.g., a + fullband signal can be decoded as wideband, or vice versa. This + approach ensures a sender and receiver can always interoperate, + regardless of the capabilities of their actual audio hardware. + Internally, the LP layer always operates at a sample rate of twice + the audio bandwidth, up to a maximum of 16 kHz, which it continues to + use for SWB and FB. The decoder simply resamples its output to + support different sample rates. The MDCT layer always operates + internally at a sample rate of 48 kHz. Since all the supported + sample rates evenly divide this rate, and since the decoder may + easily zero out the high frequency portion of the spectrum in the + frequency domain, it can simply decimate the MDCT layer output to + achieve the other supported sample rates very cheaply. + + + +Valin, et al. Standards Track [Page 9] + +RFC 6716 Interactive Audio Codec September 2012 + + + After conversion to the common, desired output sample rate, the + decoder simply adds the output from the two layers together. To + compensate for the different look-ahead required by each layer, the + CELT encoder input is delayed by an additional 2.7 ms. This ensures + that low frequencies and high frequencies arrive at the same time. + This extra delay may be reduced by an encoder by using less look- + ahead for noise shaping or using a simpler resampler in the LP layer, + but this will reduce quality. However, the base 2.5 ms look-ahead in + the CELT layer cannot be reduced in the encoder because it is needed + for the MDCT overlap, whose size is fixed by the decoder. + + Both layers use the same entropy coder, avoiding any waste from + "padding bits" between them. The hybrid approach makes it easy to + support both CBR and VBR coding. Although the LP layer is VBR, the + bit allocation of the MDCT layer can produce a final stream that is + CBR by using all the bits left unused by the LP layer. + +2.1. Control Parameters + + The Opus codec includes a number of control parameters that can be + changed dynamically during regular operation of the codec, without + interrupting the audio stream from the encoder to the decoder. These + parameters only affect the encoder since any impact they have on the + bitstream is signaled in-band such that a decoder can decode any Opus + stream without any out-of-band signaling. Any Opus implementation + can add or modify these control parameters without affecting + interoperability. The most important encoder control parameters in + the reference encoder are listed below. + +2.1.1. Bitrate + + Opus supports all bitrates from 6 kbit/s to 510 kbit/s. All other + parameters being equal, higher bitrate results in higher quality. + For a frame size of 20 ms, these are the bitrate "sweet spots" for + Opus in various configurations: + + o 8-12 kbit/s for NB speech, + + o 16-20 kbit/s for WB speech, + + o 28-40 kbit/s for FB speech, + + o 48-64 kbit/s for FB mono music, and + + o 64-128 kbit/s for FB stereo music. + + + + + + +Valin, et al. Standards Track [Page 10] + +RFC 6716 Interactive Audio Codec September 2012 + + +2.1.2. Number of Channels (Mono/Stereo) + + Opus can transmit either mono or stereo frames within a single + stream. When decoding a mono frame in a stereo decoder, the left and + right channels are identical, and when decoding a stereo frame in a + mono decoder, the mono output is the average of the left and right + channels. In some cases, it is desirable to encode a stereo input + stream in mono (e.g., because the bitrate is too low to encode stereo + with sufficient quality). The number of channels encoded can be + selected in real-time, but by default the reference encoder attempts + to make the best decision possible given the current bitrate. + +2.1.3. Audio Bandwidth + + The audio bandwidths supported by Opus are listed in Table 1. Just + like for the number of channels, any decoder can decode audio that is + encoded at any bandwidth. For example, any Opus decoder operating at + 8 kHz can decode an FB Opus frame, and any Opus decoder operating at + 48 kHz can decode an NB frame. Similarly, the reference encoder can + take a 48 kHz input signal and encode it as NB. The higher the audio + bandwidth, the higher the required bitrate to achieve acceptable + quality. The audio bandwidth can be explicitly specified in real- + time, but, by default, the reference encoder attempts to make the + best bandwidth decision possible given the current bitrate. + +2.1.4. Frame Duration + + Opus can encode frames of 2.5, 5, 10, 20, 40, or 60 ms. It can also + combine multiple frames into packets of up to 120 ms. For real-time + applications, sending fewer packets per second reduces the bitrate, + since it reduces the overhead from IP, UDP, and RTP headers. + However, it increases latency and sensitivity to packet losses, as + losing one packet constitutes a loss of a bigger chunk of audio. + Increasing the frame duration also slightly improves coding + efficiency, but the gain becomes small for frame sizes above 20 ms. + For this reason, 20 ms frames are a good choice for most + applications. + +2.1.5. Complexity + + There are various aspects of the Opus encoding process where trade- + offs can be made between CPU complexity and quality/bitrate. In the + reference encoder, the complexity is selected using an integer from 0 + to 10, where 0 is the lowest complexity and 10 is the highest. + Examples of computations for which such trade-offs may occur are: + + o The order of the pitch analysis whitening filter [WHITENING], + + + + +Valin, et al. Standards Track [Page 11] + +RFC 6716 Interactive Audio Codec September 2012 + + + o The order of the short-term noise shaping filter, + + o The number of states in delayed decision quantization of the + residual signal, and + + o The use of certain bitstream features such as variable time- + frequency resolution and the pitch post-filter. + +2.1.6. Packet Loss Resilience + + Audio codecs often exploit inter-frame correlations to reduce the + bitrate at a cost in error propagation: after losing one packet, + several packets need to be received before the decoder is able to + accurately reconstruct the speech signal. The extent to which Opus + exploits inter-frame dependencies can be adjusted on the fly to + choose a trade-off between bitrate and amount of error propagation. + +2.1.7. Forward Error Correction (FEC) + + Another mechanism providing robustness against packet loss is the in- + band Forward Error Correction (FEC). Packets that are determined to + contain perceptually important speech information, such as onsets or + transients, are encoded again at a lower bitrate and this re-encoded + information is added to a subsequent packet. + +2.1.8. Constant/Variable Bitrate + + Opus is more efficient when operating with variable bitrate (VBR), + which is the default. When low-latency transmission is required over + a relatively slow connection, then constrained VBR can also be used. + This uses VBR in a way that simulates a "bit reservoir" and is + equivalent to what MP3 (MPEG 1, Layer 3) and AAC (Advanced Audio + Coding) call CBR (i.e., not true CBR due to the bit reservoir). In + some (rare) applications, constant bitrate (CBR) is required. There + are two main reasons to operate in CBR mode: + + o When the transport only supports a fixed size for each compressed + frame, or + + o When encryption is used for an audio stream that is either highly + constrained (e.g., yes/no, recorded prompts) or highly sensitive + [SRTP-VBR]. + + Bitrate may still be allowed to vary, even with sensitive data, as + long as the variation is not driven by the input signal (for example, + to match changing network conditions). To achieve this, an + application should still run Opus in CBR mode, but change the target + rate before each packet. + + + +Valin, et al. Standards Track [Page 12] + +RFC 6716 Interactive Audio Codec September 2012 + + +2.1.9. Discontinuous Transmission (DTX) + + Discontinuous Transmission (DTX) reduces the bitrate during silence + or background noise. When DTX is enabled, only one frame is encoded + every 400 milliseconds. + +3. Internal Framing + + The Opus encoder produces "packets", which are each a contiguous set + of bytes meant to be transmitted as a single unit. The packets + described here do not include such things as IP, UDP, or RTP headers, + which are normally found in a transport-layer packet. A single + packet may contain multiple audio frames, so long as they share a + common set of parameters, including the operating mode, audio + bandwidth, frame size, and channel count (mono vs. stereo). This + section describes the possible combinations of these parameters and + the internal framing used to pack multiple frames into a single + packet. This framing is not self-delimiting. Instead, it assumes + that a lower layer (such as UDP or RTP [RFC3550] or Ogg [RFC3533] or + Matroska [MATROSKA-WEBSITE]) will communicate the length, in bytes, + of the packet, and it uses this information to reduce the framing + overhead in the packet itself. A decoder implementation MUST support + the framing described in this section. An alternative, self- + delimiting variant of the framing is described in Appendix B. + Support for that variant is OPTIONAL. + + All bit diagrams in this document number the bits so that bit 0 is + the most significant bit of the first byte, and bit 7 is the least + significant. Bit 8 is thus the most significant bit of the second + byte, etc. Well-formed Opus packets obey certain requirements, + marked [R1] through [R7] below. These are summarized in Section 3.4 + along with appropriate means of handling malformed packets. + +3.1. The TOC Byte + + A well-formed Opus packet MUST contain at least one byte [R1]. This + byte forms a table-of-contents (TOC) header that signals which of the + various modes and configurations a given packet uses.

Frame Length Coding + + When a packet contains multiple VBR frames (i.e., code 2 or 3), the + compressed length of one or more of these frames is indicated with a + one- or two-byte sequence, with the meaning of the first byte as + follows: + + o 0: No frame (Discontinuous Transmission (DTX) or lost packet) + + o 1...251: Length of the frame in bytes + + o 252...255: A second byte is needed. The total length is + (second_byte*4)+first_byte + + The special length 0 indicates that no frame is available, either + because it was dropped during transmission by some intermediary or + because the encoder chose not to transmit it. Any Opus frame in any + mode MAY have a length of 0. + + The maximum representable length is 255*4+255=1275 bytes. For 20 ms + frames, this represents a bitrate of 510 kbit/s, which is + approximately the highest useful rate for lossily compressed fullband + stereo music. Beyond this point, lossless codecs are more + appropriate. It is also roughly the maximum useful rate of the MDCT + layer as, shortly thereafter, quality no longer improves with + additional bits due to limitations on the codebook sizes. + + No length is transmitted for the last frame in a VBR packet, or for + any of the frames in a CBR packet, as it can be inferred from the + total size of the packet and the size of all other data in the + packet. However, the length of any individual frame MUST NOT exceed + 1275 bytes [R2] to allow for repacketization by gateways, conference + bridges, or other software. + +3.2.2.

The additional + padding bytes appear at the end of the packet and MUST be set to zero + by the encoder to avoid creating a covert channel. The decoder MUST + accept any value for the padding bytes, however. + + Although this encoding provides multiple ways to indicate a given + number of padding bytes, each uses a different number of bytes to + indicate the padding size and thus will increase the total packet + size by a different amount. For example, to add 255 bytes to a + packet, set the padding bit, p, to 1, insert a single byte after the + frame count byte with a value of 254, and append 254 padding bytes + with the value zero to the end of the packet. To add 256 bytes to a + packet, set the padding bit to 1, insert two bytes after the frame + count byte with the values 255 and 0, respectively, and append 254 + padding bytes with the value zero to the end of the packet. By using + the value 255 multiple times, it is possible to create a packet of + any specific, desired size. Let P be the number of header bytes used + to indicate the padding size plus the number of padding bytes + themselves (i.e., P is the total number of bytes added to the + packet). Then, P MUST be no more than N-2 [R6,R7]. + + In the CBR case, let R=N-2-P be the number of bytes remaining in the + packet after subtracting the (optional) padding.

All of the calculations in the range coder must use bit- + exact integer arithmetic. + + Symbols may also be coded as "raw bits" packed directly into the + bitstream, bypassing the range coder. These are packed backwards + starting at the end of the frame, as illustrated in Figure 12.

The parameters needed to encode or decode + symbol k in this context are represented by a three-tuple + (fl[k], fh[k], ft), all 16-bit unsigned integers, with + 0 <= fl[k] < fh[k] <= ft <= 65535. The values of this tuple are + derived from the probability model for the symbol, represented by + traditional "frequency counts".

Both val and rng are 32-bit unsigned integer + values. + +4.1.1. Range Decoder Initialization + + Let b0 be an 8-bit unsigned integer containing first input byte (or + containing zero if there are no bytes in this Opus frame).

Decoding Symbols + + Decoding a symbol is a two-step process. The first step determines a + 16-bit unsigned value fs, which lies within the range of some symbol + in the current context.

When + contexts are designed so that 0 is the most probable symbol, which is + often the case, this strategy minimizes the inefficiency introduced + by the finite precision. It also makes some of the special-case + decoding routines in Section 4.1.3 particularly simple. + + After the updates, implemented by ec_dec_update() (entdec.c), the + decoder normalizes the range using the procedure in the next section, + and returns the index k. + +4.1.2.1. Renormalization + + To normalize the range, the decoder repeats the following process, + implemented by ec_dec_normalize() (entdec.c), until rng > 2**23. If + rng is already greater than 2**23, the entire process is skipped. + First, it sets rng to (rng<<8). Then, it reads the next byte of the + Opus frame and forms an 8-bit value sym, using the leftover bit + buffered from the previous byte as the high bit and the top 7 bits of + the byte just read as the other 7 bits of sym. The remaining bit in + the byte just read is buffered for use in the next iteration. If no + more input bytes remain, it uses zero bits instead.

Standards Track [Page 29] + +RFC 6716 Interactive Audio Codec September 2012 + + + t = (t << (ftb - 8)) | ec_dec_bits(ftb - 8) + + If, at this point, t >= ft, then the current frame is corrupt. In + that case, the decoder should assume there has been an error in the + coding, decoding, or transmission and SHOULD take measures to conceal + the error (e.g., saturate to ft-1 or use the Packet Loss Concealment + (PLC)) and/or report to the application that the error has occurred. + +4.1.6. Current Bit Usage + + The bit allocation routines in the CELT decoder need a conservative + upper bound on the number of bits that have been used from the + current frame thus far, including both range coder bits and raw bits. + This drives allocation decisions that must match those made in the + encoder. The upper bound is computed in the reference implementation + to whole-bit precision by the function ec_tell() (entcode.h) and to + fractional 1/8th bit precision by the function ec_tell_frac() + (entcode.c). Like all operations in the range coder, it must be + implemented in a bit-exact manner, and it must produce exactly the + same value returned by the same functions in the encoder after + encoding the same symbols. + + ec_tell() is guaranteed to return ceil(ec_tell_frac()/8.0). In + various places, the codec will check to ensure there is enough room + to contain a symbol before attempting to decode it. In practice, + although the number of bits used so far is an upper bound, decoding a + symbol whose probability model suggests it has a worst-case cost of p + 1/8th bits may actually advance the return value of ec_tell_frac() by + p-1, p, or p+1 1/8th bits, due to approximation error in that upper + bound, truncation error in the range coder, and for large values of + ft, modeling error in ec_dec_uint(). + + However, this error is bounded, and periodic calls to ec_tell() or + ec_tell_frac() at precisely defined points in the decoding process + prevent it from accumulating. For a range coder symbol that requires + a whole number of bits (i.e., for which ft/(fh[k] - fl[k]) is a power + of two), where there are at least p 1/8th bits available, decoding + the symbol will never cause ec_tell() or ec_tell_frac() to exceed the + size of the frame ("bust the budget"). In this case, the return + value of ec_tell_frac() will only advance by more than p 1/8th bits + if there were an additional, fractional number of bits remaining, and + it will never advance beyond the next whole-bit boundary, which is + safe, since frames always contain a whole number of bits. However, + when p is not a whole number of bits, an extra 1/8th bit is required + to ensure that decoding the symbol will not bust the budget. + + + + + + +Valin, et al. Standards Track [Page 30] + +RFC 6716 Interactive Audio Codec September 2012 + + + The reference implementation keeps track of the total number of whole + bits that have been processed by the decoder so far in the variable + nbits_total, including the (possibly fractional) number of bits that + are currently buffered, but not consumed, inside the range coder. + nbits_total is initialized to 9 just before the initial range + renormalization process completes (or equivalently, it can be + initialized to 33 after the first renormalization). The extra two + bits over the actual amount buffered by the range coder guarantees + that it is an upper bound and that there is enough room for the + encoder to terminate the stream. Each iteration through the range + coder's renormalization loop increases nbits_total by 8. Reading raw + bits increases nbits_total by the number of raw bits read. + +4.1.6.1. ec_tell() + + The whole number of bits buffered in rng may be estimated via + lg = ilog(rng). ec_tell() then becomes a simple matter of removing + these bits from the total. It returns (nbits_total - lg). + + In a newly initialized decoder, before any symbols have been read, + this reports that 1 bit has been used. This is the bit reserved for + termination of the encoder. + +4.1.6.2. ec_tell_frac() + + ec_tell_frac() estimates the number of bits buffered in rng to + fractional precision. Since rng must be greater than 2**23 after + renormalization, lg must be at least 24. Let + + r_Q15 = rng >> (lg-16) + + so that 32768 <= r_Q15 < 65536, an unsigned Q15 value representing + the fractional part of rng. Then, the following procedure can be + used to add one bit of precision to lg. First, update + + r_Q15 = (r_Q15*r_Q15) >> 15 + + Then, add the 16th bit of r_Q15 to lg via + + lg = 2*lg + (r_Q15 >> 16) + + Finally, if this bit was a 1, reduce r_Q15 by a factor of two via + + r_Q15 = r_Q15 >> 1 + + so that it once again lies in the range 32768 <= r_Q15 < 65536. This + procedure is repeated three times to extend lg to 1/8th bit + precision. ec_tell_frac() then returns (nbits_total*8 - lg). + + + +Valin, et al.

SILK Decoder + + The decoder's LP layer uses a modified version of the SILK codec + (herein simply called "SILK"), which runs a decoded excitation signal + through adaptive long-term and short-term prediction synthesis + filters.

These + parameters (3, 4, 5) are used to generate an excitation signal (see + Section 4.2.7.8.6), which is fed to an optional Long-Term Prediction + (LTP) filter (voiced frames only, see Section 4.2.7.9.1) and then a + short-term prediction filter (see Section 4.2.7.9.2), producing the + decoded signal (6). For stereo streams, the mid-side representation + is converted to separate left and right channels (7). The result is + finally resampled to the desired output sample rate (e.g., 48 kHz) so + that the resampled signal (8) can be mixed with the CELT layer. + +4.2.2. LP Layer Organization + + Internally, the LP layer of a single Opus frame is composed of either + a single 10 ms regular SILK frame or between one and three 20 ms + regular SILK frames. A stereo Opus frame may double the number of + regular SILK frames (up to a total of six), since it includes + separate frames for a mid channel and, optionally, a side channel. + Optional Low Bit-Rate Redundancy (LBRR) frames, which are reduced- + bitrate encodings of previous SILK frames, may be included to aid in + recovery from packet loss. If present, these appear before the + regular SILK frames. They are, in most respects, identical to + regular, active SILK frames, except that they are usually encoded + with a lower bitrate. This document uses "SILK frame" to refer to + either one and "regular SILK frame" if it needs to draw a distinction + between the two. + + Logically, each SILK frame is, in turn, composed of either two or + four 5 ms subframes. Various parameters, such as the quantization + gain of the excitation and the pitch lag and filter coefficients can + vary on a subframe-by-subframe basis. Physically, the parameters for + each subframe are interleaved in the bitstream, as described in the + relevant sections for each parameter. + + All of these frames and subframes are decoded from the same range + coder, with no padding between them. Thus, packing multiple SILK + frames in a single Opus frame saves, on average, half a byte per SILK + frame. It also allows some parameters to be predicted from prior + SILK frames in the same Opus frame, since this does not degrade + packet loss robustness (beyond any penalty for merely using fewer, + larger packets to store multiple frames). + + Stereo support in SILK uses a variant of mid-side coding, allowing a + mono decoder to simply decode the mid channel. However, the data for + the two channels is interleaved, so a mono decoder must still unpack + + + + + +Valin, et al. Standards Track [Page 33] + +RFC 6716 Interactive Audio Codec September 2012 + + + the data for the side channel.

Header Bits + + The LP layer begins with two to eight header bits, decoded in + silk_Decode() (dec_API.c). These consist of one Voice Activity + Detection (VAD) bit per frame (up to 3), followed by a single flag + indicating the presence of LBRR frames. For a stereo packet, these + first flags correspond to the mid channel, and a second set of flags + is included for the side channel. + + + +Valin, et al. Standards Track [Page 35] + +RFC 6716 Interactive Audio Codec September 2012 + + + Because these are the first symbols decoded by the range coder and + because they are coded as binary values with uniform probability, + they can be extracted directly from the most significant bits of the + first byte of compressed data. Thus, a receiver can determine if an + Opus frame contains any active SILK frames without the overhead of + using the range decoder. + +4.2.4. Per-Frame LBRR Flags + + For Opus frames longer than 20 ms, a set of LBRR flags is decoded for + each channel that has its LBRR flag set. Each set contains one flag + per 20 ms SILK frame. 40 ms Opus frames use the 2-frame LBRR flag PDF + from Table 4, and 60 ms Opus frames use the 3-frame LBRR flag PDF. + For each channel, the resulting 2- or 3-bit integer contains the + corresponding LBRR flag for each frame, packed in order from the LSB + to the MSB. + + +------------+-------------------------------------+ + | Frame Size | PDF | + +------------+-------------------------------------+ + | 40 ms | {0, 53, 53, 150}/256 | + | | | + | 60 ms | {0, 41, 20, 29, 41, 15, 28, 82}/256 | + +------------+-------------------------------------+ + + Table 4: LBRR Flag PDFs + + A 10 or 20 ms Opus frame does not contain any per-frame LBRR flags, + as there may be at most one LBRR frame per channel. The global LBRR + flag in the header bits (see Section 4.2.3) is already sufficient to + indicate the presence of that single LBRR frame. + +4.2.5. LBRR Frames + + The LBRR frames, if present, contain an encoded representation of the + signal immediately prior to the current Opus frame as if it were + encoded with the current mode, frame size, audio bandwidth, and + channel count, even if those differ from the prior Opus frame. When + one of these parameters changes from one Opus frame to the next, this + implies that the LBRR frames of the current Opus frame may not be + simple drop-in replacements for the contents of the previous Opus + frame. + + For example, when switching from 20 ms to 60 ms, the 60 ms Opus frame + may contain LBRR frames covering up to three prior 20 ms Opus frames, + even if those frames already contained LBRR frames covering some of + the same time periods. When switching from 20 ms to 10 ms, the 10 ms + Opus frame can contain an LBRR frame covering at most half the prior + + + +Valin, et al. Standards Track [Page 36] + +RFC 6716 Interactive Audio Codec September 2012 + + + 20 ms Opus frame, potentially leaving a hole that needs to be + concealed from even a single packet loss (see Section 4.4). When + switching from mono to stereo, the LBRR frames in the first stereo + Opus frame MAY contain a non-trivial side channel. + + In order to properly produce LBRR frames under all conditions, an + encoder might need to buffer up to 60 ms of audio and re-encode it + during these transitions. However, the reference implementation opts + to disable LBRR frames at the transition point for simplicity. Since + transitions are relatively infrequent in normal usage, this does not + have a significant impact on packet loss robustness. + + The LBRR frames immediately follow the LBRR flags, prior to any + regular SILK frames. Section 4.2.7 describes their exact contents. + LBRR frames do not include their own separate VAD flags. LBRR frames + are only meant to be transmitted for active speech, thus all LBRR + frames are treated as active. + + In a stereo Opus frame longer than 20 ms, although the per-frame LBRR + flags for the mid channel are coded as a unit before the per-frame + LBRR flags for the side channel, the LBRR frames themselves are + interleaved. The decoder parses an LBRR frame for the mid channel of + a given 20 ms interval (if present) and then immediately parses the + corresponding LBRR frame for the side channel (if present), before + proceeding to the next 20 ms interval. + +4.2.6. Regular SILK Frames + + The regular SILK frame(s) follow the LBRR frames (if any). + Section 4.2.7 describes their contents, as well. Unlike the LBRR + frames, a regular SILK frame is coded for each time interval in an + Opus frame, even if the corresponding VAD flags are unset. For + stereo Opus frames longer than 20 ms, the regular mid and side SILK + frames for each 20 ms interval are interleaved, just as with the LBRR + frames. The side frame may be skipped by coding an appropriate flag, + as detailed in Section 4.2.7.2. + +4.2.7.

Stereo Prediction Weights + + A SILK frame corresponding to the mid channel of a stereo Opus frame + begins with a pair of side channel prediction weights, designed such + that zeros indicate normal mid-side coupling. Since these weights + can change on every frame, the first portion of each frame linearly + interpolates between the previous weights and the current ones, using + zeros for the previous weights if none are available. These + prediction weights are never included in a mono Opus frame, and the + previous weights are reset to zeros on any transition from mono to + stereo. They are also not included in an LBRR frame for the side + channel, even if the LBRR flags indicate the corresponding mid + channel was not coded. In that case, the previous weights are used, + again substituting in zeros if no previous weights are available + since the last decoder reset (see Section 4.5.2). + + To summarize, these weights are coded if and only if + + o This is a stereo Opus frame (Section 3.1), and + + o The current SILK frame corresponds to the mid channel. + + The prediction weights are coded in three separate pieces, which are + decoded by silk_stereo_decode_pred() (stereo_decode_pred.c).

The quantization gains are themselves uniformly + quantized to 6 bits on a log scale, giving them a resolution of + approximately 1.369 dB and a range of approximately 1.94 dB to + 88.21 dB. + + The subframe gains are either coded independently, or relative to the + gain from the most recent coded subframe in the same channel. + Independent coding is used if and only if + + + + + +Valin, et al.

Reconstructing the Normalized LSF Coefficients + + Once the stage-1 index I1 and the stage-2 residual res_Q10[] have + been decoded, the final normalized LSF coefficients can be + reconstructed. + + The spectral distortion introduced by the quantization of each LSF + coefficient varies, so the stage-2 residual is weighted accordingly, + using the low-complexity Inverse Harmonic Mean Weighting (IHMW) + function proposed in [LAROIA-ICASSP].

These parameters are held in the e_prob_model table in + quant_bands.c. The coarse energy decoding is performed by + unquant_coarse_energy() (quant_bands.c). The decoding of the + Laplace-distributed values is implemented in ec_laplace_decode() + (laplace.c). + +4.3.2.2. Fine Energy Quantization + + The number of bits assigned to fine energy quantization in each band + is determined by the bit allocation computation described in + Section 4.3.3. Let B_i be the number of fine energy bits for band i; + the refinement is an integer f in the range [0,2**B_i-1]. The + mapping between f and the correction applied to the coarse energy is + equal to (f+1/2)/2**B_i - 1/2. Fine energy quantization is + implemented in quant_fine_energy() (quant_bands.c). + + When some bits are left "unused" after all other flags have been + decoded, these bits are assigned to a "final" step of fine + allocation. In effect, these bits are used to add one extra fine + energy bit per band per channel. The allocation process determines + two "priorities" for the final fine bits. Any remaining bits are + first assigned only to bands of priority 0, starting from band 0 and + going up. If all bands of priority 0 have received one bit per + channel, then bands of priority 1 are assigned an extra bit per + channel, starting from band 0. If any bits are left after this, they + are left unused. This is implemented in unquant_energy_finalise() + (quant_bands.c). + + + + + + +Valin, et al. Standards Track [Page 109] + +RFC 6716 Interactive Audio Codec September 2012 + + +4.3.3. Bit Allocation + + Because the bit allocation drives the decoding of the range-coder + stream, it MUST be recovered exactly so that identical coding + decisions are made in the encoder and decoder. Any deviation from + the reference's resulting bit allocation will result in corrupted + output, though implementers are free to implement the procedure in + any way that produces identical results. + + The per-band gain-shape structure of the CELT layer ensures that + using the same number of bits for the spectral shape of a band in + every frame will result in a roughly constant signal-to-noise ratio + in that band. This results in coding noise that has the same + spectral envelope as the signal. The masking curve produced by a + standard psychoacoustic model also closely follows the spectral + envelope of the signal. This structure means that the ideal + allocation is more consistent from frame to frame than it is for + other codecs without an equivalent structure and that a fixed + allocation provides fairly consistent perceptual + performance [VALIN2010]. + + Many codecs transmit significant amounts of side information to + control the bit allocation within a frame. Often this control is + only indirect, and it must be exercised carefully to achieve the + desired rate constraints. The CELT layer, however, can adapt over a + very wide range of rates, so it has a large number of codebook sizes + to choose from for each band. Explicitly signaling the size of each + of these codebooks would impose considerable overhead, even though + the allocation is relatively static from frame to frame. This is + because all of the information required to compute these codebook + sizes must be derived from a single frame by itself, in order to + retain robustness to packet loss, so the signaling cannot take + advantage of knowledge of the allocation in neighboring frames. This + problem is exacerbated in low-latency (small frame size) + applications, which would include this overhead in every frame. + + For this reason, in the MDCT mode, Opus uses a primarily implicit bit + allocation. The available bitstream capacity is known in advance to + both the encoder and decoder without additional signaling, ultimately + from the packet sizes expressed by a higher-level protocol. Using + this information, the codec interpolates an allocation from a hard- + coded table. + + While the band-energy structure effectively models intra-band + masking, it ignores the weaker inter-band masking, band-temporal + masking, and other less significant perceptual effects. While these + effects can often be ignored, they can become significant for + particular samples. One mechanism available to encoders would be to + + + +Valin, et al. Standards Track [Page 110] + +RFC 6716 Interactive Audio Codec September 2012 + + + simply increase the overall rate for these frames, but this is not + possible in a constant rate mode and can be fairly inefficient. As a + result three explicitly signaled mechanisms are provided to alter the + implicit allocation: + + o Band boost + + o Allocation trim + + o Band skipping + + The first of these mechanisms, band boost, allows an encoder to boost + the allocation in specific bands. The second, allocation trim, works + by biasing the overall allocation towards higher or lower frequency + bands. The third, band skipping, selects which low-precision high + frequency bands will be allocated no shape bits at all. + + In stereo mode, there are two additional parameters potentially coded + as part of the allocation procedure: a parameter to allow the + selective elimination of allocation for the 'side' (i.e., intensity + stereo) in jointly coded bands, and a flag to deactivate joint coding + (i.e., dual stereo). These values are not signaled if they would be + meaningless in the overall context of the allocation. + + Because every signaled adjustment increases overhead and + implementation complexity, none were included speculatively: the + reference encoder makes use of all of these mechanisms. While the + decision logic in the reference was found to be effective enough to + justify the overhead and complexity, further analysis techniques may + be discovered that increase the effectiveness of these parameters. + As with other signaled parameters, an encoder is free to choose the + values in any manner, but, unless a technique is known to deliver + superior perceptual results, the methods used by the reference + implementation should be used. + + The allocation process consists of the following steps: determining + the per-band maximum allocation vector, decoding the boosts, decoding + the tilt, determining the remaining capacity of the frame, searching + the mode table for the entry nearest but not exceeding the available + space (subject to the tilt, boosts, band maximums, and band + minimums), linear interpolation, reallocation of unused bits with + concurrent skip decoding, determination of the fine-energy vs. shape + split, and final reallocation. This process results in a per-band + shape allocation (in 1/8th-bit units), a per-band fine-energy + allocation (in 1 bit per channel units), a set of band priorities for + controlling the use of remaining bits at the end of the frame, and a + remaining balance of unallocated space, which is usually zero except + at very high rates. + + + +Valin, et al. Standards Track [Page 111] + +RFC 6716 Interactive Audio Codec September 2012 + + + The "static" bit allocation (in 1/8 bits) for a quality q, excluding + the minimums, maximums, tilt and boosts, is equal to + channels*N*alloc[band][q]<>2, where alloc[][] is given in + Table 57 and LM=log2(frame_size/120).

The default coding cost for a boost starts out at + six bits (probability p=1/64), but subsequent boosts in a band cost + only a single bit and every time a band is boosted the initial cost + is reduced (down to a minimum of two bits, or p=1/4). Since the + + + + +Valin, et al. Standards Track [Page 113] + +RFC 6716 Interactive Audio Codec September 2012 + + + initial cost of coding a boost is 6 bits, the coding cost of the + boost symbols when completely unused is 0.48 bits/frame for a 21 band + mode (21*-log2(1-1/2**6)). + + To decode the band boosts: First, set 'dynalloc_logp' to 6, the + initial amount of storage required to signal a boost in bits, + 'total_bits' to the size of the frame in 8th bits, 'total_boost' to + zero, and 'tell' to the total number of 8th bits decoded so far. For + each band from the coding start (0 normally, but 17 in Hybrid mode) + to the coding end (which changes depending on the signaled + bandwidth), the boost quanta in units of 1/8 bit is calculated as + quanta = min(8*N, max(48, N)). This represents a boost step size of + six bits, subject to a lower limit of 1/8th bit/sample and an upper + limit of 1 bit/sample. Set 'boost' to zero and 'dynalloc_loop_logp' + to dynalloc_logp. While dynalloc_loop_log (the current worst case + symbol cost) in 8th bits plus tell is less than total_bits plus + total_boost and boost is less than cap[] for this band: Decode a bit + from the bitstream with dynalloc_loop_logp as the cost of a one and + update tell to reflect the current used capacity. If the decoded + value is zero break the loop. Otherwise, add quanta to boost and + total_boost, subtract quanta from total_bits, and set + dynalloc_loop_log to 1. When the loop finishes 'boost' contains the + bit allocation boost for this band. If boost is non-zero and + dynalloc_logp is greater than 2, decrease dynalloc_logp. Once this + process has been executed on all bands, the band boosts have been + decoded. This procedure is implemented around line 2474 of celt.c. + + At very low rates, it is possible that there won't be enough + available space to execute the inner loop even once. In these cases, + band boost is not possible, but its overhead is completely + eliminated.

Following this, one + bit is reserved for dual stereo if available. + + The allocation computation begins by setting up some initial + conditions.

For each coded band take the + alloc_trim and subtract 5 and LM. Then, multiply the result by the + number of channels, the number of MDCT bins in the shortest frame + size for this mode, the number of remaining bands, 2**LM, and 8. + Next, divide this value by 64. Finally, if the number of MDCT bins + in the band per channel is only one, 8 times the number of channels + is subtracted in order to diminish the allocation by one bit, because + width 1 bands receive greater benefit from the coarse energy coding. + +4.3.4. Shape Decoding + + In each band, the normalized "shape" is encoded using Pyramid Vector + Quantizer. + + In the simplest case, the number of bits allocated in Section 4.3.3 + is converted to a number of pulses as described by Section 4.3.4.1. + Knowing the number of pulses and the number of samples in the band, + the decoder calculates the size of the codebook as detailed in + Section 4.3.4.2. The size is used to decode an unsigned integer + (uniform probability model), which is the codeword index. This index + is converted into the corresponding vector as explained in + Section 4.3.4.2. This vector is then scaled to unit norm. + +4.3.4.1. Bits to Pulses + + Although the allocation is performed in 1/8th bit units, the + quantization requires an integer number of pulses K. To do this, the + encoder searches for the value of K that produces the number of bits + nearest to the allocated value (rounding down if exactly halfway + between two values), not to exceed the total number of bits + available. For efficiency reasons, the search is performed against a + precomputed allocation table that only permits some K values for each + N. The number of codebook entries can be computed as explained in + Section 4.3.4.2. The difference between the number of bits allocated + and the number of bits used is accumulated to a "balance" + (initialized to zero) that helps adjust the allocation for the next + bands. One third of the balance is applied to the bit allocation of + each band to help achieve the target allocation. The only exceptions + are the band before the last and the last band, for which half the + balance and the whole balance are applied, respectively. + + + + + +Valin, et al.

PVQ Decoding + + Decoding of PVQ vectors is implemented in decode_pulses() (cwrs.c). + The unique codeword index is decoded as a uniformly distributed + integer value between 0 and V(N,K)-1, where V(N,K) is the number of + possible combinations of K pulses in N samples. The index is then + converted to a vector in the same way specified in [PVQ]. The + indexing is based on the calculation of V(N,K) (denoted N(L,K) in + [PVQ]). + + The number of combinations can be computed recursively as V(N,K) = + V(N-1,K) + V(N,K-1) + V(N-1,K-1), with V(N,0) = 1 and V(0,K) = 0, K + != 0. There are many different ways to compute V(N,K), including + precomputed tables and direct use of the recursive formulation. The + reference implementation applies the recursive formulation one line + (or column) at a time to save on memory use, along with an alternate, + univariate recurrence to initialize an arbitrary line, and direct + polynomial solutions for small N. All of these methods are + equivalent, and have different trade-offs in speed, memory usage, and + code size. Implementations MAY use any methods they like, as long as + they are equivalent to the mathematical definition. + + The decoded vector X is recovered as follows. Let i be the index + decoded with the procedure in Section 4.1.5 with ft = V(N,K), so that + 0 <= i < V(N,K). Let k = K. Then, for j = 0 to (N - 1), inclusive, + do: + + 1.

Anti-collapse Processing + + The anti-collapse feature is designed to avoid the situation where + the use of multiple short MDCTs causes the energy in one or more of + the MDCTs to be zero for some bands, causing unpleasant artifacts. + When the frame has the transient bit set, an anti-collapse bit is + decoded. When anti-collapse is set, the energy in each small MDCT is + prevented from collapsing to zero. For each band of each MDCT where + a collapse is detected, a pseudo-random signal is inserted with an + + + +Valin, et al. Standards Track [Page 120] + +RFC 6716 Interactive Audio Codec September 2012 + + + energy corresponding to the minimum energy over the two previous + frames. A renormalization step is then required to ensure that the + anti-collapse step did not alter the energy preservation property. + +4.3.6. Denormalization + + Just as each band was normalized in the encoder, the last step of the + decoder before the inverse MDCT is to denormalize the bands. Each + decoded normalized band is multiplied by the square root of the + decoded energy. This is done by denormalise_bands() (bands.c). + +4.3.7. Inverse MDCT + + The inverse MDCT implementation has no special characteristics. The + input is N frequency-domain samples and the output is 2*N time-domain + samples, while scaling by 1/2. A "low-overlap" window reduces the + algorithmic delay. It is derived from a basic (full-overlap) 240- + sample version of the window used by the Vorbis codec: + + 2 + / /pi /pi n + 1/2\ \ \ + W(n) = |sin|-- * sin|-- * -------| | | + \ \2 \2 L / / / + + The low-overlap window is created by zero-padding the basic window + and inserting ones in the middle, such that the resulting window + still satisfies power complementarity [PRINCEN86]. The IMDCT and + windowing are performed by mdct_backward (mdct.c). + +4.3.7.1. Post-Filter + + The output of the inverse MDCT (after weighted overlap-add) is sent + to the post-filter. Although the post-filter is applied at the end, + the post-filter parameters are encoded at the beginning, just after + the silence flag. The post-filter can be switched on or off using + one bit (logp=1). If the post-filter is enabled, then the octave is + decoded as an integer value between 0 and 6 of uniform probability. + Once the octave is known, the fine pitch within the octave is decoded + using 4+octave raw bits.

Opus Encoder + + Just like the decoder, the Opus encoder also normally consists of two + main blocks: the SILK encoder and the CELT encoder. However, unlike + the case of the decoder, a valid (though potentially suboptimal) Opus + encoder is not required to support all modes and may thus only + include a SILK encoder module or a CELT encoder module. The output + bitstream of the Opus encoding contains bits from the SILK and CELT + encoders, though these are not separable due to the use of a range + coder. A block diagram of the encoder is illustrated below. + + +------------+ +---------+ + | Sample | | SILK |------+ + +->| Rate |--->| Encoder | V + +-----------+ | | Conversion | | | +---------+ + | Optional | | +------------+ +---------+ | Range | + ->| High-pass |--+ | Encoder |----> + | Filter | | +--------------+ +---------+ | | Bit- + +-----------+ | | Delay | | CELT | +---------+ stream + +->| Compensation |->| Encoder | ^ + | | | |------+ + +--------------+ +---------+ + + Figure 20: Opus Encoder + + For a normal encoder where both the SILK and the CELT modules are + included, an optimal encoder should select which coding mode to use + at run-time depending on the conditions. In the reference + implementation, the frame size is selected by the application, but + the other configuration parameters (number of channels, bandwidth, + mode) are automatically selected (unless explicitly overridden by the + application) depending on the following: + + o Requested bitrate + + o Input sampling rate + + o Type of signal (speech vs. music) + + o Frame size in use + + The type of signal currently needs to be provided by the application + (though it can be changed in real-time). An Opus encoder + implementation could also do automatic detection, but since Opus is + an interactive codec, such an implementation would likely have to + either delay the signal (for non-interactive applications) or delay + the mode switching decisions (for interactive applications). + + + + +Valin, et al. Standards Track [Page 131] + +RFC 6716 Interactive Audio Codec September 2012 + + + When the encoder is configured for voice over IP applications, the + input signal is filtered by a high-pass filter to remove the lowest + part of the spectrum that contains little speech energy and may + contain background noise. This is a second order Auto Regressive + Moving Average (i.e., with poles and zeros) filter with a cut-off + frequency around 50 Hz. In the future, a music detector may also be + used to lower the cut-off frequency when the input signal is detected + to be music rather than speech. + +5.1. Range Encoder + + The range coder acts as the bit-packer for Opus. It is used in three + different ways: to encode + + o Entropy-coded symbols with a fixed probability model using + ec_encode() (entenc.c), + + o Integers from 0 to (2**M - 1) using ec_enc_uint() or ec_enc_bits() + (entenc.c), + + o Integers from 0 to (ft - 1) (where ft is not a power of two) using + ec_enc_uint() (entenc.c). + + The range encoder maintains an internal state vector composed of the + four-tuple (val, rng, rem, ext) representing the low end of the + current range, the size of the current range, a single buffered + output byte, and a count of additional carry-propagating output + bytes. Both val and rng are 32-bit unsigned integer values, rem is a + byte value or less than 255 or the special value -1, and ext is an + unsigned integer with at least 11 bits. This state vector is + initialized at the start of each frame to the value + (0, 2**31, -1, 0). After encoding a sequence of symbols, the value + of rng in the encoder should exactly match the value of rng in the + decoder after decoding the same sequence of symbols. This is a + powerful tool for detecting errors in either an encoder or decoder + implementation. The value of val, on the other hand, represents + different things in the encoder and decoder, and is not expected to + match. + + The decoder has no analog for rem and ext. These are used to perform + carry propagation in the renormalization loop below. Each iteration + of this loop produces 9 bits of output, consisting of 8 data bits and + a carry flag. The encoder cannot determine the final value of the + output bytes until it propagates these carry flags. Therefore, the + reference implementation buffers a single non-propagating output byte + (i.e., one less than 255) in rem and keeps a count of additional + + + + + +Valin, et al. Standards Track [Page 132] + +RFC 6716 Interactive Audio Codec September 2012 + + + propagating (i.e., 255) output bytes in ext. An implementation may + choose to use any mathematically equivalent scheme to perform carry + propagation. + +5.1.1. Encoding Symbols + + The main encoding function is ec_encode() (entenc.c), which encodes + symbol k in the current context using the same three-tuple + (fl[k], fh[k], ft) as the decoder to describe the range of the symbol + (see Section 4.1). + + ec_encode() updates the state of the encoder as follows. If fl[k] is + greater than zero, then + + rng + val = val + rng - --- * (ft - fl) + ft + + rng + rng = --- * (fh - fl) + ft + + Otherwise, val is unchanged and + + rng + rng = rng - --- * (fh - fl) + ft + + The divisions here are integer division. + +5.1.1.1. Renormalization + + After this update, the range is normalized using a procedure very + similar to that of Section 4.1.2.1, implemented by ec_enc_normalize() + (entenc.c). The following process is repeated until rng > 2**23. + First, the top 9 bits of val, (val>>23), are sent to the carry + buffer, described in Section 5.1.1.2. Then, the encoder sets + + val = (val<<8) & 0x7FFFFFFF + + rng = rng<<8 + +5.1.1.2. Carry Propagation and Output Buffering + + The function ec_enc_carry_out() (entenc.c) implements carry + propagation and output buffering. It takes, as input, a 9-bit + unsigned value, c, consisting of 8 data bits and an additional carry + + + + +Valin, et al. Standards Track [Page 133] + +RFC 6716 Interactive Audio Codec September 2012 + + + bit. If c is equal to the value 255, then ext is simply incremented, + and no other state updates are performed. Otherwise, let b = (c>>8) + be the carry bit. Then, + + o If the buffered byte rem contains a value other than -1, the + encoder outputs the byte (rem + b). Otherwise, if rem is -1, no + byte is output. + + o If ext is non-zero, then the encoder outputs ext bytes -- all with + a value of 0 if b is set, or 255 if b is unset -- and sets ext to + 0. + + o rem is set to the 8 data bits: + + rem = c & 255 + +5.1.2. Alternate Encoding Methods + + The reference implementation uses three additional encoding methods + that are exactly equivalent to the above, but make assumptions and + simplifications that allow for a more efficient implementation. + +5.1.2.1. ec_encode_bin() + + The first is ec_encode_bin() (entenc.c), defined using the parameter + ftb instead of ft. It is mathematically equivalent to calling + ec_encode() with ft = (1<>(ftb - 8), (t>>(ftb - 8)) + 1, + ((ft - 1)>>(ftb - 8)) + 1), and the remaining bits, + (t & ((1<<(ftb - 8)) - 1), are encoded as raw bits with + ec_enc_bits(). + +5.1.5. Finalizing the Stream + + After all symbols are encoded, the stream must be finalized by + outputting a value inside the current range. Let end be the unsigned + integer in the interval [val, val + rng) with the largest number of + trailing zero bits, b, such that (end + (1<>23), + are passed to the carry buffer in accordance with the procedure in + Section 5.1.1.2, and end is updated via + + end = (end<<8) & 0x7FFFFFFF + + Finally, if the buffered output byte, rem, is neither zero nor the + special value -1, or the carry count, ext, is greater than zero, then + 9 zero bits are sent to the carry buffer to flush it to the output + buffer. When outputting the final byte from the range coder, if it + would overlap any raw bits already packed into the end of the output + buffer, they should be ORed into the same byte. The bit allocation + routines in the CELT layer should ensure that this can be done + without corrupting the range coder data so long as end is chosen as + described above. If there is any space between the end of the range + coder data and the end of the raw bits, it is padded with zero bits. + This entire process is implemented by ec_enc_done() (entenc.c). + +5.1.6. Current Bit Usage + + The bit allocation routines in Opus need to be able to determine a + conservative upper bound on the number of bits that have been used to + encode the current frame thus far. This drives allocation decisions + and ensures that the range coder and raw bits will not overflow the + output buffer. This is computed in the reference implementation to + whole-bit precision by the function ec_tell() (entcode.h) and to + fractional 1/8th bit precision by the function ec_tell_frac() + (entcode.c). Like all operations in the range coder, it must be + implemented in a bit-exact manner, and it must produce exactly the + same value returned by the same functions in the decoder after + decoding the same symbols. + +5.2. SILK Encoder + + In many respects, the SILK encoder mirrors the SILK decoder described + in Section 4.2. Details such as the quantization and range coder + tables can be found there, while this section describes the high- + level design choices that were made. The diagram below shows the + basic modules of the SILK encoder. + + +----------+ +--------+ +---------+ + | Sample | | Stereo | | SILK | + ------>| Rate |--->| Mixing |--->| Core |----------> + Input |Conversion| | | | Encoder | Bitstream + +----------+ +--------+ +---------+ + + Figure 21: SILK Encoder + + + + +Valin, et al. Standards Track [Page 136] + +RFC 6716 Interactive Audio Codec September 2012 + + +5.2.1. Sample Rate Conversion + + The input signal's sampling rate is adjusted by a sample rate + conversion module so that it matches the SILK internal sampling rate. + The input to the sample rate converter is delayed by a number of + samples depending on the sample rate ratio, such that the overall + delay is constant for all input and output sample rates. + +5.2.2. Stereo Mixing + + The stereo mixer is only used for stereo input signals. It converts + a stereo left-right signal into an adaptive mid-side representation. + The first step is to compute non-adaptive mid-side signals as half + the sum and difference between left and right signals. The side + signal is then minimized in energy by subtracting a prediction of it + based on the mid signal. This prediction works well when the left + and right signals exhibit linear dependency, for instance, for an + amplitude-panned input signal. Like in the decoder, the prediction + coefficients are linearly interpolated during the first 8 ms of the + frame. The mid signal is always encoded, whereas the residual side + signal is only encoded if it has sufficient energy compared to the + mid signal's energy. If it has not, the "mid_only_flag" is set + without encoding the side signal. + + The predictor coefficients are coded regardless of whether the side + signal is encoded. For each frame, two predictor coefficients are + computed, one that predicts between low-passed mid and side channels, + and one that predicts between high-passed mid and side channels. The + low-pass filter is a simple three-tap filter and creates a delay of + one sample. The high-pass filtered signal is the difference between + the mid signal delayed by one sample and the low-passed signal. + Instead of explicitly computing the high-passed signal, it is + computationally more efficient to transform the prediction + coefficients before applying them to the filtered mid signal, as + follows: + + pred(n) = LP(n) * w0 + HP(n) * w1 + = LP(n) * w0 + (mid(n-1) - LP(n)) * w1 + = LP(n) * (w0 - w1) + mid(n-1) * w1 + + + where w0 and w1 are the low-pass and high-pass prediction + coefficients, mid(n-1) is the mid signal delayed by one sample, LP(n) + and HP(n) are the low-passed and high-passed signals and pred(n) is + the prediction signal that is subtracted from the side signal. + + + + + + +Valin, et al.

Voice Activity Detection + + The input signal is processed by a Voice Activity Detection (VAD) + algorithm to produce a measure of voice activity, spectral tilt, and + signal-to-noise estimates for each frame. The VAD uses a sequence of + half-band filterbanks to split the signal into four subbands: + 0...Fs/16, Fs/16...Fs/8, Fs/8...Fs/4, and Fs/4...Fs/2, where Fs is + the sampling frequency (8, 12, 16, or 24 kHz). The lowest subband, + from 0 - Fs/16, is high-pass filtered with a first-order moving + average (MA) filter (with transfer function H(z) = 1-z**(-1)) to + reduce the energy at the lowest frequencies. For each frame, the + signal energy per subband is computed. In each subband, a noise + level estimator tracks the background noise level and a Signal-to- + Noise Ratio (SNR) value is computed as the logarithm of the ratio of + energy-to-noise level. Using these intermediate variables, the + following parameters are calculated for use in other SILK modules: + + o Average SNR. The average of the subband SNR values. + + o Smoothed subband SNRs.

The analysis consists of three stages for + reducing the complexity: + + + + + +Valin, et al. Standards Track [Page 140] + +RFC 6716 Interactive Audio Codec September 2012 + + + o In the first stage, the whitened signal is downsampled to 4 kHz + (from 8 kHz), and the current frame is correlated to a signal + delayed by a range of lags, starting from a shortest lag + corresponding to 500 Hz, to a longest lag corresponding to 56 Hz. + + o The second stage operates on an 8 kHz signal (downsampled from 12, + 16, or 24 kHz) and measures time correlations only near the lags + corresponding to those that had sufficiently high correlations in + the first stage. The resulting correlations are adjusted for a + small bias towards short lags to avoid ending up with a multiple + of the true pitch lag. The highest adjusted correlation is + compared to a threshold depending on: + + * Whether the previous frame was classified as voiced. + + * The speech activity level. + + * The spectral tilt. + + If the threshold is exceeded, the current frame is classified as + voiced and the lag with the highest adjusted correlation is stored + for a final pitch analysis of the highest precision in the third + stage. + + o The last stage operates directly on the whitened input signal to + compute time correlations for each of the four subframes + independently in a narrow range around the lag with highest + correlation from the second stage. + +5.2.3.3. Noise Shaping Analysis + + The noise shaping analysis finds gains and filter coefficients used + in the pre-filter and noise shaping quantizer. These parameters are + chosen such that they will fulfill several requirements: + + o Balancing quantization noise and bitrate. The quantization gains + determine the step size between reconstruction levels of the + excitation signal. Therefore, increasing the quantization gain + amplifies quantization noise, but also reduces the bitrate by + lowering the entropy of the quantization indices. + + o Spectral shaping of the quantization noise; the noise shaping + quantizer is capable of reducing quantization noise in some parts + of the spectrum at the cost of increased noise in other parts + without substantially changing the bitrate. By shaping the noise + such that it follows the signal spectrum, it becomes less audible. + In practice, best results are obtained by making the shape of the + noise spectrum slightly flatter than the signal spectrum. + + + +Valin, et al. Standards Track [Page 141] + +RFC 6716 Interactive Audio Codec September 2012 + + + o De-emphasizing spectral valleys; by using different coefficients + in the analysis and synthesis part of the pre-filter and noise + shaping quantizer, the levels of the spectral valleys can be + decreased relative to the levels of the spectral peaks such as + speech formants and harmonics. This reduces the entropy of the + signal, which is the difference between the coded signal and the + quantization noise, thus lowering the bitrate. + + o Matching the levels of the decoded speech formants to the levels + of the original speech formants; an adjustment gain and a first + order tilt coefficient are computed to compensate for the effect + of the noise shaping quantization on the level and spectral tilt. + + / \ ___ + | // \\ + | // \\ ____ + |_// \\___// \\ ____ + | / ___ \ / \\ // \\ + P |/ / \ \_/ \\_____// \\ + o | / \ ____ \ / \\ + w | / \___/ \ \___/ ____ \\___ 1 + e |/ \ / \ \ + r | \_____/ \ \__ 2 + | \ + | \___ 3 + | + +----------------------------------------> + Frequency + + 1: Input signal spectrum + 2: De-emphasized and level matched spectrum + 3: Quantization noise spectrum + + Figure 24: Noise Shaping and Spectral De-emphasis Illustration + + Figure 24 shows an example of an input signal spectrum (1).

This + bandwidth expansion moves the roots of the LPC polynomial towards the + origin, using the formulas + + k + a_ana(k) = a(k)*g_ana and + + k + a_syn(k) = a(k)*g_syn + + where a(k) is the k'th LPC coefficient, and the bandwidth expansion + factors g_ana and g_syn are calculated as + + g_ana = 0.95 - 0.01*C and + + g_syn = 0.95 + 0.01*C + + where C is the coding quality control parameter between 0 and 1. + Applying more bandwidth expansion to the analysis part than to the + synthesis part gives the desired de-emphasis of spectral valleys in + between formants. + + The long-term shaping is applied only during voiced frames. It uses + a three-tap filter, described by + + b_ana = F_ana * [0.25, 0.5, 0.25] and + + b_syn = F_syn * [0.25, 0.5, 0.25]. + + For unvoiced frames, these coefficients are set to 0. The + multiplication factors F_ana and F_syn are chosen between 0 and 1, + depending on the coding quality control parameter, as well as the + calculated pitch correlation and smoothed subband SNR of the lowest + subband. By having F_ana less than F_syn, the pitch harmonics are + emphasized relative to the valleys in between the harmonics. + + The tilt coefficient c_tilt is for unvoiced frames chosen as + + c_tilt = 0.25 + + and as + + c_tilt = 0.25 + 0.2625 * V + + for voiced frames, where V is the voice activity level between 0 and + 1. + + + +Valin, et al. Standards Track [Page 144] + +RFC 6716 Interactive Audio Codec September 2012 + + + The adjustment gain G serves to correct any level mismatch between + the original and decoded signals that might arise from the noise + shaping and de-emphasis. This gain is computed as the ratio of the + prediction gain of the short-term analysis and synthesis filter + coefficients. The prediction gain of an LPC synthesis filter is the + square root of the output energy when the filter is excited by a + unit-energy impulse on the input. An efficient way to compute the + prediction gain is by first computing the reflection coefficients + from the LPC coefficients through the step-down algorithm, and + extracting the prediction gain from the reflection coefficients as + + K + ___ 2 -0.5 + predGain = ( | | 1 - (r_k) ) + k=1 + + where r_k is the k'th reflection coefficient. + + Initial values for the quantization gains are computed as the square + root of the residual energy of the LPC analysis, adjusted by the + coding quality control parameter. These quantization gains are later + adjusted based on the results of the prediction analysis. + +5.2.3.4. Prediction Analysis + + The prediction analysis is performed in one of two ways depending on + how the pitch estimator classified the frame. The processing for + voiced and unvoiced speech is described in Section 5.2.3.4.1 and + Section 5.2.3.4.2, respectively. Inputs to this function include the + pre-whitened signal from the pitch estimator (see Section 5.2.3.2). + +5.2.3.4.1. Voiced Speech + + For a frame of voiced speech, the pitch pulses will remain dominant + in the pre-whitened input signal. Further whitening is desirable as + it leads to higher quality at the same available bitrate. To achieve + this, a Long-Term Prediction (LTP) analysis is carried out to + estimate the coefficients of a fifth-order LTP filter for each of + four subframes. The LTP coefficients are quantized using the method + described in Section 5.2.3.6, and the quantized LTP coefficients are + used to compute the LTP residual signal. This LTP residual signal is + the input to an LPC analysis where the LPC coefficients are estimated + using Burg's method [BURG], such that the residual energy is + minimized. The estimated LPC coefficients are converted to a Line + Spectral Frequency (LSF) vector and quantized as described in + Section 5.2.3.5. After quantization, the quantized LSF vector is + converted back to LPC coefficients using the full procedure in + Section 4.2.7.5. By using quantized LTP coefficients and LPC + + + +Valin, et al. Standards Track [Page 145] + +RFC 6716 Interactive Audio Codec September 2012 + + + coefficients derived from the quantized LSF coefficients, the encoder + remains fully synchronized with the decoder. The quantized LPC and + LTP coefficients are also used to filter the input signal and measure + residual energy for each of the four subframes. + +5.2.3.4.2. Unvoiced Speech + + For a speech signal that has been classified as unvoiced, there is no + need for LTP filtering, as it has already been determined that the + pre-whitened input signal is not periodic enough within the allowed + pitch period range for LTP analysis to be worth the cost in terms of + complexity and bitrate. The pre-whitened input signal is therefore + discarded, and, instead, the input signal is used for LPC analysis + using Burg's method. The resulting LPC coefficients are converted to + an LSF vector and quantized as described in the following section. + They are then transformed back to obtain quantized LPC coefficients, + which are then used to filter the input signal and measure residual + energy for each of the four subframes. + +5.2.3.4.2.1. Burg's Method + + The main purpose of linear prediction in SILK is to reduce the + bitrate by minimizing the residual energy. At least at high + bitrates, perceptual aspects are handled independently by the noise + shaping filter. Burg's method is used because it provides higher + prediction gain than the autocorrelation method and, unlike the + covariance method, produces stable filters (assuming numerical errors + don't spoil that). SILK's implementation of Burg's method is also + computationally faster than the autocovariance method. The + implementation of Burg's method differs from traditional + implementations in two aspects. The first difference is that it + operates on autocorrelations, similar to the Schur algorithm [SCHUR], + but with a simple update to the autocorrelations after finding each + reflection coefficient to make the result identical to Burg's method. + This brings down the complexity of Burg's method to near that of the + autocorrelation method. The second difference is that the signal in + each subframe is scaled by the inverse of the residual quantization + step size. Subframes with a small quantization step size will, on + average, spend more bits for a given amount of residual energy than + subframes with a large step size. Without scaling, Burg's method + minimizes the total residual energy in all subframes, which doesn't + necessarily minimize the total number of bits needed for coding the + quantized residual. The residual energy of the scaled subframes is a + better measure for that number of bits. + + + + + + + +Valin, et al. Standards Track [Page 146] + +RFC 6716 Interactive Audio Codec September 2012 + + +5.2.3.5. LSF Quantization + + Unlike many other speech codecs, SILK uses variable bitrate coding + for the LSFs. This improves the average rate-distortion (R-D) trade- + off and reduces outliers. The variable bitrate coding minimizes a + linear combination of the weighted quantization errors and the + bitrate. The weights for the quantization errors are the Inverse + Harmonic Mean Weighting (IHMW) function proposed by Laroia et al. + (see [LAROIA-ICASSP]). These weights are referred to here as Laroia + weights. + + The LSF quantizer consists of two stages. The first stage is an + (unweighted) vector quantizer (VQ), with a codebook size of 32 + vectors. The quantization errors for the codebook vector are sorted, + and for the N best vectors a second stage quantizer is run. By + varying the number N, a trade-off is made between R-D performance and + computational efficiency. For each of the N codebook vectors, the + Laroia weights corresponding to that vector (and not to the input + vector) are calculated. Then, the residual between the input LSF + vector and the codebook vector is scaled by the square roots of these + Laroia weights. This scaling partially normalizes error sensitivity + for the residual vector so that a uniform quantizer with fixed step + sizes can be used in the second stage without too much performance + loss. Additionally, by scaling with Laroia weights determined from + the first-stage codebook vector, the process can be reversed in the + decoder. + + The second stage uses predictive delayed decision scalar + quantization. The quantization error is weighted by Laroia weights + determined from the LSF input vector. The predictor multiplies the + previous quantized residual value by a prediction coefficient that + depends on the vector index from the first stage VQ and on the + location in the LSF vector. The prediction is subtracted from the + LSF residual value before quantizing the result and is added back + afterwards. This subtraction can be interpreted as shifting the + quantization levels of the scalar quantizer, and as a result the + quantization error of each value depends on the quantization decision + of the previous value. This dependency is exploited by the delayed + decision mechanism to search for a quantization sequency with best + R-D performance with a Viterbi-like algorithm [VITERBI]. The + quantizer processes the residual LSF vector in reverse order (i.e., + it starts with the highest residual LSF value). This is done because + the prediction works slightly better in the reverse direction. + + + + + + + + +Valin, et al. Standards Track [Page 147] + +RFC 6716 Interactive Audio Codec September 2012 + + + The quantization index of the first stage is entropy coded. The + quantization sequence from the second stage is also entropy coded, + where for each element the probability table is chosen depending on + the vector index from the first stage and the location of that + element in the LSF vector. + +5.2.3.5.1. LSF Stabilization + + If the input is stable, finding the best candidate usually results in + a quantized vector that is also stable. Because of the two-stage + approach, however, it is possible that the best quantization + candidate is unstable. The encoder applies the same stabilization + procedure applied by the decoder (see Section 4.2.7.5.4) to ensure + the LSF parameters are within their valid range, increasingly sorted, + and have minimum distances between each other and the border values. + +5.2.3.6. LTP Quantization + + For voiced frames, the prediction analysis described in + Section 5.2.3.4.1 resulted in four sets (one set per subframe) of + five LTP coefficients, plus four weighting matrices. The LTP + coefficients for each subframe are quantized using entropy + constrained vector quantization. A total of three vector codebooks + are available for quantization, with different rate-distortion trade- + offs. The three codebooks have 10, 20, and 40 vectors and average + rates of about 3, 4, and 5 bits per vector, respectively. + Consequently, the first codebook has larger average quantization + distortion at a lower rate, whereas the last codebook has smaller + average quantization distortion at a higher rate. Given the + weighting matrix W_ltp and LTP vector b, the weighted rate-distortion + measure for a codebook vector cb_i with rate r_i is give by + + RD = u * (b - cb_i)' * W_ltp * (b - cb_i) + r_i + + where u is a fixed, heuristically determined parameter balancing the + distortion and rate. Which codebook gives the best performance for a + given LTP vector depends on the weighting matrix for that LTP vector. + For example, for a low valued W_ltp, it is advantageous to use the + codebook with 10 vectors as it has a lower average rate. For a large + W_ltp, on the other hand, it is often better to use the codebook with + 40 vectors, as it is more likely to contain the best codebook vector. + The weighting matrix W_ltp depends mostly on two aspects of the input + signal. The first is the periodicity of the signal; the more + periodic, the larger W_ltp. The second is the change in signal + energy in the current subframe, relative to the signal one pitch lag + earlier. A decaying energy leads to a larger W_ltp than an + increasing energy. Both aspects fluctuate relatively slowly, which + causes the W_ltp matrices for different subframes of one frame often + + + +Valin, et al. Standards Track [Page 148] + +RFC 6716 Interactive Audio Codec September 2012 + + + to be similar. Because of this, one of the three codebooks typically + gives good performance for all subframes. Therefore, the codebook + search for the subframe LTP vectors is constrained to only allow + codebook vectors to be chosen from the same codebook, resulting in a + rate reduction. + + To find the best codebook, each of the three vector codebooks is used + to quantize all subframe LTP vectors and produce a combined weighted + rate-distortion measure for each vector codebook. The vector + codebook with the lowest combined rate-distortion over all subframes + is chosen. The quantized LTP vectors are used in the noise shaping + quantizer, and the index of the codebook plus the four indices for + the four subframe codebook vectors are passed on to the range + encoder. + +5.2.3.7. Pre-filter + + In the pre-filter, the input signal is filtered using the spectral + valley de-emphasis filter coefficients from the noise shaping + analysis (see Section 5.2.3.3). By applying only the noise shaping + analysis filter to the input signal, it provides the input to the + noise shaping quantizer. + +5.2.3.8. Noise Shaping Quantizer + + The noise shaping quantizer independently shapes the signal and + coding noise spectra to obtain a perceptually higher quality at the + same bitrate. + + The pre-filter output signal is multiplied with a compensation gain G + computed in the noise shaping analysis. Then, the output of a + synthesis shaping filter is added, and the output of a prediction + filter is subtracted to create a residual signal. The residual + signal is multiplied by the inverse quantized quantization gain from + the noise shaping analysis and input to a scalar quantizer. The + quantization indices of the scalar quantizer represent a signal of + pulses that is input to the pyramid range encoder. The scalar + quantizer also outputs a quantization signal, which is multiplied by + the quantized quantization gain from the noise shaping analysis to + create an excitation signal. The output of the prediction filter is + added to the excitation signal to form the quantized output signal + y(n). The quantized output signal y(n) is input to the synthesis + shaping and prediction filters. + + + + + + + + +Valin, et al. Standards Track [Page 149] + +RFC 6716 Interactive Audio Codec September 2012 + + + Optionally, the noise shaping quantizer operates in a delayed + decision mode. In this mode, it uses a Viterbi algorithm to keep + track of multiple rounding choices in the quantizer and select the + best one after a delay of 32 samples. This improves the rate/ + distortion performance of the quantizer. + +5.2.3.9. Constant Bitrate Mode + + SILK was designed to run in variable bitrate (VBR) mode. However, + the reference implementation also has a constant bitrate (CBR) mode + for SILK. In CBR mode, SILK will attempt to encode each packet with + no more than the allowed number of bits. The Opus wrapper code then + pads the bitstream if any unused bits are left in SILK mode, or it + encodes the high band with the remaining number of bits in Hybrid + mode. The number of payload bits is adjusted by changing the + quantization gains and the rate/distortion trade-off in the noise + shaping quantizer, in an iterative loop around the noise shaping + quantizer and entropy coding. Compared to the SILK VBR mode, the CBR + mode has lower audio quality at a given average bitrate and has + higher computational complexity. + +5.3. CELT Encoder + + Most of the aspects of the CELT encoder can be directly derived from + the description of the decoder. For example, the filters and + rotations in the encoder are simply the inverse of the operation + performed by the decoder. Similarly, the quantizers generally + optimize for the mean square error (because noise shaping is part of + the bitstream itself), so no special search is required. For this + reason, only the less straightforward aspects of the encoder are + described here. + +5.3.1. Pitch Pre-filter + + The pitch pre-filter is applied after the pre-emphasis. It is + applied in such a way as to be the inverse of the decoder's post- + filter. The main non-obvious aspect of the pre-filter is the + selection of the pitch period. The pitch search should be optimized + for the following criteria: + + o continuity: it is important that the pitch period does not change + abruptly between frames; and + + o avoidance of pitch multiples: when the period used is a multiple + of the real period (lower frequency fundamental), the post-filter + loses most of its ability to reduce noise + + + + + +Valin, et al. Standards Track [Page 150] + +RFC 6716 Interactive Audio Codec September 2012 + + +5.3.2. Bands and Normalization + + The MDCT output is divided into bands that are designed to match the + ear's critical bands for the smallest (2.5 ms) frame size. The + larger frame sizes use integer multiples of the 2.5 ms layout. For + each band, the encoder computes the energy that will later be + encoded. Each band is then normalized by the square root of the + *unquantized* energy, such that each band now forms a unit vector X. + The energy and the normalization are computed by + compute_band_energies() and normalise_bands() (bands.c), + respectively. + +5.3.3. Energy Envelope Quantization + + Energy quantization (both coarse and fine) can be easily understood + from the decoding process. For all useful bitrates, the coarse + quantizer always chooses the quantized log energy value that + minimizes the error for each band. Only at very low rate does the + encoder allow larger errors to minimize the rate and avoid using more + bits than are available. When the available CPU requirements allow + it, it is best to try encoding the coarse energy both with and + without inter-frame prediction such that the best prediction mode can + be selected. The optimal mode depends on the coding rate, the + available bitrate, and the current rate of packet loss. + + The fine energy quantizer always chooses the quantized log energy + value that minimizes the error for each band because the rate of the + fine quantization depends only on the bit allocation and not on the + values that are coded. + +5.3.4. Bit Allocation + + The encoder must use exactly the same bit allocation process as used + by the decoder and described in Section 4.3.3. The three mechanisms + that can be used by the encoder to adjust the bitrate on a frame-by- + frame basis are band boost, allocation trim, and band skipping. + +5.3.4.1. Band Boost + + The reference encoder makes a decision to boost a band when the + energy of that band is significantly higher than that of the + neighboring bands. Let E_j be the log-energy of band j, we define + + D_j = 2*E_j - E_j-1 - E_j+1 + + The allocation of band j is boosted once if D_j > t1 and twice if D_j + > t2. For LM>=1, t1=2 and t2=4, while for LM<1, t1=3 and t2=5. + + + + +Valin, et al. Standards Track [Page 151] + +RFC 6716 Interactive Audio Codec September 2012 + + +5.3.4.2. Allocation Trim + + The allocation trim is a value between 0 and 10 (inclusively) that + controls the allocation balance between the low and high frequencies. + The encoder starts with a safe "default" of 5 and deviates from that + default in two different ways. First, the trim can deviate by +/- 2 + depending on the spectral tilt of the input signal. For signals with + more low frequencies, the trim is increased by up to 2, while for + signals with more high frequencies, the trim is decreased by up to 2. + For stereo inputs, the trim value can be decreased by up to 4 when + the inter-channel correlation at low frequency (first 8 bands) is + high. + +5.3.4.3. Band Skipping + + The encoder uses band skipping to ensure that the shape of the bands + is only coded if there is at least 1/2 bit per sample available for + the PVQ. If not, then no bit is allocated and folding is used + instead. To ensure continuity in the allocation, some amount of + hysteresis is added to the process, such that a band that received + PVQ bits in the previous frame only needs 7/16 bit/sample to be coded + for the current frame, while a band that did not receive PVQ bits in + the previous frames needs at least 9/16 bit/sample to be coded. + +5.3.5. Stereo Decisions + + Because CELT applies mid-side stereo coupling in the normalized + domain, it does not suffer from important stereo image problems even + when the two channels are completely uncorrelated. For this reason, + it is always safe to use stereo coupling on any audio frame. That + being said, there are some frames for which dual (independent) stereo + is still more efficient. This decision is made by comparing the + estimated entropy with and without coupling over the first 13 bands, + taking into account the fact that all bands with more than two MDCT + bins require one extra degree of freedom when coded in mid-side. Let + L1_ms and L1_lr be the L1-norm of the mid-side vector and the L1-norm + of the left-right vector, respectively. The decision to use mid-side + is made if and only if + + L1_ms L1_lr + -------- < ----- + bins + E bins + + where bins is the number of MDCT bins in the first 13 bands and E is + the number of extra degrees of freedom for mid-side coding. For + LM>1, E=13, otherwise E=5. + + + + + +Valin, et al. Standards Track [Page 152] + +RFC 6716 Interactive Audio Codec September 2012 + + + The reference encoder decides on the intensity stereo threshold based + on the bitrate alone. After taking into account the frame size by + subtracting 80 bits per frame for coarse energy, the first band using + intensity coding is as follows: + + +------------------+------------+ + | bitrate (kbit/s) | start band | + +------------------+------------+ + | <35 | 8 | + | | | + | 35-50 | 12 | + | | | + | 50-68 | 16 | + | | | + | 84-84 | 18 | + | | | + | 84-102 | 19 | + | | | + | 102-130 | 20 | + | | | + | >130 | disabled | + +------------------+------------+ + + Table 66: Thresholds for Intensity Stereo + +5.3.6. Time-Frequency Decision + + The choice of time-frequency resolution used in Section 4.3.4.5 is + based on R-D optimization. The distortion is the L1-norm (sum of + absolute values) of each band after each TF resolution under + consideration. The L1 norm is used because it represents the entropy + for a Laplacian source. The number of bits required to code a change + in TF resolution between two bands is higher than the cost of having + those two bands use the same resolution, which is what requires the + R-D optimization. The optimal decision is computed using the Viterbi + algorithm. See tf_analysis() in celt/celt.c. + +5.3.7. Spreading Values Decision + + The choice of the spreading value in Table 59 has an impact on the + nature of the coding noise introduced by CELT. The larger the f_r + value, the lower the impact of the rotation, and the more tonal the + coding noise. The more tonal the signal, the more tonal the noise + should be, so the CELT encoder determines the optimal value for f_r + by estimating how tonal the signal is. The tonality estimate is + based on discrete pdf (4-bin histogram) of each band. Bands that + + + + + +Valin, et al. Standards Track [Page 153] + +RFC 6716 Interactive Audio Codec September 2012 + + + have a large number of small values are considered more tonal and a + decision is made by combining all bands with more than 8 samples. + See spreading_decision() in celt/bands.c. + +5.3.8. Spherical Vector Quantization + + CELT uses a Pyramid Vector Quantizer (PVQ) [PVQ] for quantizing the + details of the spectrum in each band that have not been predicted by + the pitch predictor. The PVQ codebook consists of all sums of K + signed pulses in a vector of N samples, where two pulses at the same + position are required to have the same sign. Thus, the codebook + includes all integer codevectors y of N dimensions that satisfy + sum(abs(y(j))) = K. + + In bands where there are sufficient bits allocated, PVQ is used to + encode the unit vector that results from the normalization in + Section 5.3.2 directly. Given a PVQ codevector y, the unit vector X + is obtained as X = y/||y||, where ||.|| denotes the L2 norm. + +5.3.8.1. PVQ Search + + The search for the best codevector y is performed by alg_quant() + (vq.c). There are several possible approaches to the search, with a + trade-off between quality and complexity. The method used in the + reference implementation computes an initial codeword y1 by + projecting the normalized spectrum X onto the codebook pyramid of K-1 + pulses: + + y0 = truncate_towards_zero( (K-1) * X / sum(abs(X))) + + Depending on N, K and the input data, the initial codeword y0 may + contain from 0 to K-1 non-zero values. All the remaining pulses, + with the exception of the last one, are found iteratively with a + greedy search that minimizes the normalized correlation between y and + X: + + T + J = -X * y / ||y|| + + The search described above is considered to be a good trade-off + between quality and computational cost. However, there are other + possible ways to search the PVQ codebook and the implementers MAY use + any other search methods. See alg_quant() in celt/vq.c. + + + + + + + + +Valin, et al. Standards Track [Page 154] + +RFC 6716 Interactive Audio Codec September 2012 + + +5.3.8.2. PVQ Encoding + + The vector to encode, X, is converted into an index i such that + 0 <= i < V(N,K) as follows. Let i = 0 and k = 0. Then, for + j = (N - 1) down to 0, inclusive, do: + + 1. If k > 0, set i = i + (V(N-j-1,k-1) + V(N-j,k-1))/2. + + 2. Set k = k + abs(X[j]). + + 3. If X[j] < 0, set i = i + (V(N-j-1,k) + V(N-j,k))/2. + + The index i is then encoded using the procedure in Section 5.1.4 with + ft = V(N,K). + +6. Conformance + + It is our intention to allow the greatest possible choice of freedom + in implementing the specification. For this reason, outside of the + exceptions noted in this section, conformance is defined through the + reference implementation of the decoder provided in Appendix A. + Although this document includes a prose description of the codec, + should the description contradict the source code of the reference + implementation, the latter shall take precedence. + + Compliance with this specification means that, in addition to + following the normative keywords in this document, a decoder's output + MUST also be within the thresholds specified by the opus_compare.c + tool (included with the code) when compared to the reference + implementation for each of the test vectors provided (see + Appendix A.4) and for each output sampling rate and channel count + supported. In addition, a compliant decoder implementation MUST have + the same final range decoder state as that of the reference decoder. + It is therefore RECOMMENDED that the decoder implement the same + functional behavior as the reference. A decoder implementation is + not required to support all output sampling rates or all output + channel counts. + +6.1. Testing + + Using the reference code provided in Appendix A, a test vector can be + decoded with + + opus_demo -d testvectorX.bit testX.out + + where is the sampling rate and can be 8000, 12000, 16000, + 24000, or 48000, and is 1 for mono or 2 for stereo. + + + + +Valin, et al. Standards Track [Page 155] + +RFC 6716 Interactive Audio Codec September 2012 + + + If the range decoder state is incorrect for one of the frames, the + decoder will exit with "Error: Range coder state mismatch between + encoder and decoder". If the decoder succeeds, then the output can + be compared with the "reference" output with + + opus_compare -s -r testvectorX.dec testX.out + + for stereo or + + opus_compare -r testvectorX.dec testX.out + + for mono. + + In addition to indicating whether the test vector comparison passes, + the opus_compare tool outputs an "Opus quality metric" that indicates + how well the tested decoder matches the reference implementation. A + quality of 0 corresponds to the passing threshold, while a quality of + 100 is the highest possible value and means that the output of the + tested decoder is identical to the reference implementation. The + passing threshold (quality 0) was calibrated in such a way that it + corresponds to additive white noise with a 48 dB SNR (similar to what + can be obtained on a cassette deck). It is still possible for an + implementation to sound very good with such a low quality measure + (e.g., if the deviation is due to inaudible phase distortion), but + unless this is verified by listening tests, it is RECOMMENDED that + implementations achieve a quality above 90 for 48 kHz decoding. For + other sampling rates, it is normal for the quality metric to be lower + (typically, as low as 50 even for a good implementation) because of + harmless mismatch with the delay and phase of the internal sampling + rate conversion. + + On POSIX environments, the run_vectors.sh script can be used to + verify all test vectors. This can be done with + + run_vectors.sh + + where is the directory where the opus_demo and + opus_compare executables are built and is the directory + containing the test vectors. + +6.2. Opus Custom + + Opus Custom is an OPTIONAL part of the specification that is defined + to handle special sample rates and frame rates that are not supported + by the main Opus specification. Use of Opus Custom is discouraged + for all but very special applications for which a frame size + different from 2.5, 5, 10, or 20 ms is needed (for either complexity + or latency reasons). Because Opus Custom is optional, streams + + + +Valin, et al. Standards Track [Page 156] + +RFC 6716 Interactive Audio Codec September 2012 + + + encoded using Opus Custom cannot be expected to be decodable by all + Opus implementations. Also, because no in-band mechanism exists for + specifying the sampling rate and frame size of Opus Custom streams, + out-of-band signaling is required. In Opus Custom operation, only + the CELT layer is available, using the opus_custom_* function calls + in opus_custom.h. + +7. Security Considerations + + Like any other audio codec, Opus should not be used with insecure + ciphers or cipher-modes that are vulnerable to known plaintext + attacks. In addition to the zeros used in Opus padding, digital + silence frames generate predictable compressed results and the TOC + byte may have an easily predictable value. + + Implementations of the Opus codec need to take appropriate security + considerations into account, as outlined in [DOS]. It is extremely + important for the decoder to be robust against malicious payloads. + Malicious payloads must not cause the decoder to overrun its + allocated memory or to take an excessive amount of resources to + decode. Although problems in encoders are typically rarer, the same + applies to the encoder. Malicious audio streams must not cause the + encoder to misbehave because this would allow an attacker to attack + transcoding gateways. + + The reference implementation contains no known buffer overflow or + cases where a specially crafted packet or audio segment could cause a + significant increase in CPU load. However, on certain CPU + architectures where denormalized floating-point operations are much + slower than normal floating-point operations, it is possible for some + audio content (e.g., silence or near silence) to cause an increase in + CPU load. Denormals can be introduced by reordering operations in + the compiler and depend on the target architecture, so it is + difficult to guarantee that an implementation avoids them. For + architectures on which denormals are problematic, adding very small + floating-point offsets to the affected signals to prevent significant + numbers of denormalized operations is RECOMMENDED. Alternatively, it + is often possible to configure the hardware to treat denormals as + zero (DAZ). No such issue exists for the fixed-point reference + implementation. + + The reference implementation was validated in the following + conditions: + + 1. Sending the decoder valid packets generated by the reference + encoder and verifying that the decoder's final range coder state + matches that of the encoder. + + + + +Valin, et al. Standards Track [Page 157] + +RFC 6716 Interactive Audio Codec September 2012 + + + 2. Sending the decoder packets generated by the reference encoder + and then subjected to random corruption. + + 3. Sending the decoder random packets. + + 4. Sending the decoder packets generated by a version of the + reference encoder modified to make random coding decisions + (internal fuzzing), including mode switching, and verifying that + the range coder final states match. + + In all of the conditions above, both the encoder and the decoder were + run inside the Valgrind [VALGRIND] memory debugger, which tracks + reads and writes to invalid memory regions as well as the use of + uninitialized memory. There were no errors reported on any of the + tested conditions. + +8.

Reference Implementation + + This appendix contains the complete source code for the reference + implementation of the Opus codec written in C. By default, this + implementation relies on floating-point arithmetic, but it can be + compiled to use only fixed-point arithmetic by defining the + FIXED_POINT macro. The normative behavior is defined as the output + using the floating-point configuration. Information on building and + using the reference implementation is available in the README file. + + The implementation can be compiled with either a C89 or a C99 + compiler. It is reasonably optimized for most platforms such that + only architecture-specific optimizations are likely to be useful. + The Fast Fourier Transform (FFT) [FFT] used is a slightly modified + version of the KISS-FFT library, but it is easy to substitute any + other FFT library. + + While the reference implementation does not rely on any _undefined + behavior_ as defined by C89 or C99, it relies on common + _implementation-defined behavior_ for two's complement architectures: + + o Right shifts of negative values are consistent with two's + complement arithmetic, so that a>>b is equivalent to + floor(a/(2**b)), + + o For conversion to a signed integer of N bits, the value is reduced + modulo 2**N to be within range of the type, + + o The result of integer division of a negative value is truncated + towards zero, and + + o The compiler provides a 64-bit integer type (a C99 requirement + which is supported by most C89 compilers). + + In its current form, the reference implementation also requires the + following architectural characteristics to obtain acceptable + performance: + + o Two's complement arithmetic, + + o At least a 16 bit by 16 bit integer multiplier (32-bit result), + and + + o At least a 32-bit adder/accumulator. + + + + + + + +Valin, et al.

Self-Delimiting Framing + + To use the internal framing described in Section 3, the decoder must + know the total length of the Opus packet, in bytes. This section + describes a simple variation of that framing that can be used when + the total length of the packet is not known.

It is RECOMMENDED + that a transport layer choose exactly one framing scheme, rather than + allowing an encoder to signal which one it wants to use. + + For example, although a regular Opus stream does not support more + than two channels, a multi-channel Opus stream may be formed from + several one- and two-channel streams. To pack an Opus packet from + each of these streams together in a single packet at the transport + layer, one could use the self-delimiting framing for all but the last + stream, and then the regular, undelimited framing for the last one. + Reverting to the undelimited framing for the last stream saves + overhead (because the total size of the transport-layer packet will + still be known), and ensures that a "multi-channel" stream that only + has a single Opus stream uses the same framing as a regular Opus + stream does. This avoids the need for signaling to distinguish these + two cases. + + The self-delimiting framing is identical to the regular, undelimited + framing from Section 3, except that each Opus packet contains one + extra length field, encoded using the same one- or two-byte scheme + from Section 3.2.1. This extra length immediately precedes the + compressed data of the first Opus frame in the packet, and is + interpreted in the various modes as follows: + + o Code 0 packets: It is the length of the single Opus frame (see + Figure 25). + + o Code 1 packets: It is the length used for both of the Opus frames + (see Figure 26). + + o Code 2 packets: It is the length of the second Opus frame (see + Figure 27). + + o CBR Code 3 packets: It is the length used for all of the Opus + frames (see Figure 28). + + o VBR Code 3 packets: It is the length of the last Opus frame (see + Figure 29). + + + + + + + + + + + + + +Valin, et al.

Introduction + + This document addresses minor issues that were discovered in the + reference implementation of the Opus codec. Unlike most IETF + specifications, RFC 6716 [RFC6716] defines Opus in terms of a + normative reference decoder implementation rather than from the + associated text description. Appendix A of that RFC includes the + reference decoder implementation, which is why only issues affecting + the decoder are listed here. An up-to-date implementation of the + Opus encoder can be found at . + + Some of the changes in this document update normative behavior in a + way that requires new test vectors. Only the C implementation is + affected, not the English text of the specification. This + specification remains fully compatible with RFC 6716 [RFC6716]. + + Note: Due to RFC formatting conventions, lines exceeding the column + width in the patch are split using a backslash character. The + backslashes at the end of a line and the white space at the beginning + of the following line are not part of the patch. Referenced line + numbers are approximations. A properly formatted patch including all + changes is available at and has a SHA-1 hash of + 029e3aa88fc342c91e67a21e7bfbc9458661cd5f. + + + + + + + + +Valin & Vos Standards Track [Page 2] + +RFC 8251 Opus Update October 2017 + + +2. Terminology + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and + "OPTIONAL" in this document are to be interpreted as described in + BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all + capitals, as shown here. + +3. Stereo State Reset in SILK + + The reference implementation does not reinitialize the stereo state + during a mode switch. The old stereo memory can produce a brief + impulse (i.e., single sample) in the decoded audio. This can be + fixed by changing silk/dec_API.c around line 72: + + + for( n = 0; n < DECODER_NUM_CHANNELS; n++ ) { + ret = silk_init_decoder( &channel_state[ n ] ); + } + + silk_memset(&((silk_decoder *)decState)->sStereo, 0, + + sizeof(((silk_decoder *)decState)->sStereo)); + + /* Not strictly needed, but it's cleaner that way */ + + ((silk_decoder *)decState)->prev_decode_only_middle = 0; + + return ret; + } + + + This change affects the normative output of the decoder, but the + amount of change is within the tolerance and is too small to make the + test vector check fail. + + + + + + + + + + + + + + + + + + + + +Valin & Vos Standards Track [Page 3] + +RFC 8251 Opus Update October 2017 + + +4. Parsing of the Opus Packet Padding + + It was discovered that some invalid packets of a very large size + could trigger an out-of-bounds read in the Opus packet parsing code + responsible for padding. This is due to an integer overflow if the + signaled padding exceeds 2^31-1 bytes (the actual packet may be + smaller). The code can be fixed by decrementing the (signed) len + value, instead of incrementing a separate padding counter. This is + done by applying the following changes around line 596 of + src/opus_decoder.c: + + + /* Padding flag is bit 6 */ + if (ch&0x40) + { + - int padding=0; + int p; + do { + if (len<=0) + return OPUS_INVALID_PACKET; + p = *data++; + len--; + - padding += p==255 ? 254: p; + + len -= p==255 ? 254: p; + } while (p==255); + - len -= padding; + } + + + This packet-parsing issue is limited to reading memory up to about 60 + KB beyond the compressed buffer. This can only be triggered by a + compressed packet more than about 16 MB long, so it's not a problem + for RTP. In theory, it could crash a file decoder (e.g., Opus in + Ogg) if the memory just after the incoming packet is out of range, + but our attempts to trigger such a crash in a production application + built using an affected version of the Opus decoder failed. + +5. Resampler Buffer + + The SILK resampler had the following issues: + + 1. The calls to memcpy() were using sizeof(opus_int32), but the type + of the local buffer was opus_int16. + + + + + + + + +Valin & Vos Standards Track [Page 4] + +RFC 8251 Opus Update October 2017 + + + 2. Because the size was wrong, this potentially allowed the source + and destination regions of the memcpy() to overlap on the copy + from "buf" to "buf". We believe that nSamplesIn (number of input + samples) is at least fs_in_khZ (sampling rate in kHz), which is + at least 8. Since RESAMPLER_ORDER_FIR_12 is only 8, that should + not be a problem once the type size is fixed. + + 3. The size of the buffer used RESAMPLER_MAX_BATCH_SIZE_IN, but the + data stored in it was actually twice the input batch size + (nSamplesIn<<1). + + The code can be fixed by applying the following changes around line + 78 of silk/resampler_private_IIR_FIR.c: + + + + ) + { + silk_resampler_state_struct *S = \ + (silk_resampler_state_struct *)SS; + opus_int32 nSamplesIn; + opus_int32 max_index_Q16, index_increment_Q16; + - opus_int16 buf[ RESAMPLER_MAX_BATCH_SIZE_IN + \ + RESAMPLER_ORDER_FIR_12 ]; + + opus_int16 buf[ 2*RESAMPLER_MAX_BATCH_SIZE_IN + \ + RESAMPLER_ORDER_FIR_12 ]; + + /* Copy buffered samples to start of buffer */ + - silk_memcpy( buf, S->sFIR, RESAMPLER_ORDER_FIR_12 \ + * sizeof( opus_int32 ) ); + + silk_memcpy( buf, S->sFIR, RESAMPLER_ORDER_FIR_12 \ + * sizeof( opus_int16 ) ); + + /* Iterate over blocks of frameSizeIn input samples */ + index_increment_Q16 = S->invRatio_Q16; + while( 1 ) { + nSamplesIn = silk_min( inLen, S->batchSize ); + + /* Upsample 2x */ + silk_resampler_private_up2_HQ( S->sIIR, &buf[ \ + RESAMPLER_ORDER_FIR_12 ], in, nSamplesIn ); + + max_index_Q16 = silk_LSHIFT32( nSamplesIn, 16 + 1 \ + ); /* + 1 because 2x upsampling */ + out = silk_resampler_private_IIR_FIR_INTERPOL( out, \ + buf, max_index_Q16, index_increment_Q16 ); + in += nSamplesIn; + inLen -= nSamplesIn; + + + +Valin & Vos Standards Track [Page 5] + +RFC 8251 Opus Update October 2017 + + + if( inLen > 0 ) { + /* More iterations to do; copy last part of \ + filtered signal to beginning of buffer */ + - silk_memcpy( buf, &buf[ nSamplesIn << 1 ], \ + RESAMPLER_ORDER_FIR_12 * sizeof( opus_int32 ) ); + + silk_memmove( buf, &buf[ nSamplesIn << 1 ], \ + RESAMPLER_ORDER_FIR_12 * sizeof( opus_int16 ) ); + } else { + break; + } + } + + /* Copy last part of filtered signal to the state for \ + the next call */ + - silk_memcpy( S->sFIR, &buf[ nSamplesIn << 1 ], \ + RESAMPLER_ORDER_FIR_12 * sizeof( opus_int32 ) ); + + silk_memcpy( S->sFIR, &buf[ nSamplesIn << 1 ], \ + RESAMPLER_ORDER_FIR_12 * sizeof( opus_int16 ) ); + } + + +6. Integer Wrap-Around in Inverse Gain Computation + + It was discovered through decoder fuzzing that some bitstreams could + produce integer values exceeding 32 bits in + LPC_inverse_pred_gain_QA(), causing a wrap-around. The C standard + considers this behavior as undefined. The following patch around + line 87 of silk/LPC_inv_pred_gain.c detects values that do not fit in + a 32-bit integer and considers the corresponding filters unstable: + + + /* Update AR coefficient */ + for( n = 0; n < k; n++ ) { + - tmp_QA = Aold_QA[ n ] - MUL32_FRAC_Q( \ + Aold_QA[ k - n - 1 ], rc_Q31, 31 ); + - Anew_QA[ n ] = MUL32_FRAC_Q( tmp_QA, rc_mult2 , mult2Q ); + + opus_int64 tmp64; + + tmp_QA = silk_SUB_SAT32( Aold_QA[ n ], MUL32_FRAC_Q( \ + Aold_QA[ k - n - 1 ], rc_Q31, 31 ) ); + + tmp64 = silk_RSHIFT_ROUND64( silk_SMULL( tmp_QA, \ + rc_mult2 ), mult2Q); + + if( tmp64 > silk_int32_MAX || tmp64 < silk_int32_MIN ) { + + return 0; + + } + + Anew_QA[ n ] = ( opus_int32 )tmp64; + } + + + + + +Valin & Vos Standards Track [Page 6] + +RFC 8251 Opus Update October 2017 + + +7. Integer Wrap-Around in LSF Decoding + + It was discovered -- also from decoder fuzzing -- that an integer + wrap-around could occur when decoding bitstreams with extremely large + values for the high Line Spectral Frequency (LSF) parameters. The + end result of the wrap-around is an illegal read access on the stack, + which the authors do not believe is exploitable but should + nonetheless be fixed. The following patch around line 137 of silk/ + NLSF_stabilize.c prevents the problem: + + + /* Keep delta_min distance between the NLSFs */ + for( i = 1; i < L; i++ ) + - NLSF_Q15[i] = silk_max_int( NLSF_Q15[i], \ + NLSF_Q15[i-1] + NDeltaMin_Q15[i] ); + + NLSF_Q15[i] = silk_max_int( NLSF_Q15[i], \ + silk_ADD_SAT16( NLSF_Q15[i-1], NDeltaMin_Q15[i] ) ); + + /* Last NLSF should be no higher than 1 - NDeltaMin[L] */ + + +8. Cap on Band Energy + + On extreme bitstreams, it is possible for log-domain band energy + levels to exceed the maximum single-precision floating point value + once converted to a linear scale. This would later cause the decoded + values to be NaN (not a number), possibly causing problems in the + software using the PCM values. This can be avoided with the + following patch around line 552 of celt/quant_bands.c: + + + { + opus_val16 lg = ADD16(oldEBands[i+c*m->nbEBands], + SHL16((opus_val16)eMeans[i],6)); + + lg = MIN32(QCONST32(32.f, 16), lg); + eBands[i+c*m->nbEBands] = PSHR32(celt_exp2(lg),4); + } + for (;inbEBands;i++) + + + + + + + + + + + + + +Valin & Vos Standards Track [Page 7] + +RFC 8251 Opus Update October 2017 + + +9. Hybrid Folding + + When encoding in hybrid mode at low bitrate, we sometimes only have + enough bits to code a single Constrained-Energy Lapped Transform + (CELT) band (8 - 9.6 kHz). When that happens, the second band (CELT + band 18, from 9.6 - 12 kHz) cannot use folding because it is wider + than the amount already coded and falls back to white noise. Because + it can also happen on transients (e.g., stops), it can cause audible + pre-echo. + + To address the issue, we change the folding behavior so that it is + never forced to fall back to Linear Congruential Generator (LCG) due + to the first band not containing enough coefficients to fold onto the + second band. This is achieved by simply repeating part of the first + band in the folding of the second band. This changes the code in + celt/bands.c around line 1237: + + + b = 0; + } + + - if (resynth && M*eBands[i]-N >= M*eBands[start] && \ + (update_lowband || lowband_offset==0)) + + if (resynth && (M*eBands[i]-N >= M*eBands[start] || \ + i==start+1) && (update_lowband || lowband_offset==0)) + lowband_offset = i; + + + if (i == start+1) + + { + + int n1, n2; + + int offset; + + n1 = M*(eBands[start+1]-eBands[start]); + + n2 = M*(eBands[start+2]-eBands[start+1]); + + offset = M*eBands[start]; + + /* Duplicate enough of the first band folding data to \ + be able to fold the second band. + + Copies no data for CELT-only mode. */ + + OPUS_COPY(&norm[offset+n1], &norm[offset+2*n1 - n2], n2-n1); + + if (C==2) + + OPUS_COPY(&norm2[offset+n1], &norm2[offset+2*n1 - n2], \ + n2-n1); + + } + + + tf_change = tf_res[i]; + if (i>=m->effEBands) + { + + + + + +Valin & Vos Standards Track [Page 8] + +RFC 8251 Opus Update October 2017 + + + as well as around line 1260: + + + fold_start = lowband_offset; + while(M*eBands[--fold_start] > effective_lowband); + fold_end = lowband_offset-1; + - while(M*eBands[++fold_end] < effective_lowband+N); + + while(++fold_end < i && M*eBands[fold_end] < \ + effective_lowband+N); + x_cm = y_cm = 0; + fold_i = fold_start; do { + x_cm |= collapse_masks[fold_i*C+0]; + + + + The fix does not impact compatibility, because the improvement does + not depend on the encoder doing anything special. There is also no + reasonable way for an encoder to use the original behavior to improve + quality over the proposed change. + +10. Downmix to Mono + + The last issue is not strictly a bug, but it is an issue that has + been reported when downmixing an Opus decoded stream to mono, whether + this is done inside the decoder or as a post-processing step on the + stereo decoder output. Opus intensity stereo allows optionally + coding the two channels 180 degrees out of phase on a per-band basis. + This provides better stereo quality than forcing the two channels to + be in phase, but when the output is downmixed to mono, the energy in + the affected bands is canceled, sometimes resulting in audible + artifacts. + + As a work-around for this issue, the decoder MAY choose not to apply + the 180-degree phase shift. This can be useful when downmixing to + mono inside or outside of the decoder (e.g., requested explicitly + from an API). + +11. New Test Vectors + + Changes in Sections 9 and 10 have sufficient impact on the test + vectors to make them fail. For this reason, this document also + updates the Opus test vectors. The new test vectors now include two + decoded outputs for the same bitstream. The outputs with suffix 'm' + do not apply the CELT 180-degree phase shift as allowed in + Section 10, while the outputs without the suffix do.

CVE-2013-0899 + theoretically could have caused an information leak. The leaked + information would have gone through the decoder process before being + accessible to the attacker. The update in Section 4 fixes this. + CVE-2017-0381 could have resulted in a 16-bit out-of-bounds read from + a fixed location. The update in Section 7 fixes this.
