## Frame based filter bank and cepstral analysis

sig2fbank | Calculate the (log) energy (or power) in each channel of a Mel scale filter bank for a frame of speech.
sig2fft | Calculate the energy (or power) spectrum of a frame of speech.
fft2fbank | Given a Mel filter bank description, bin the FFT coefficients to compute the output of the filters.
fbank2melcep | Compute the dicrete cosine transform of log Mel-scale filter bank output to get the Mel cepstral coeffecients for a frame of speech.
make_mel_triangular_filter | Make a triangular Mel scale filter.
Frequency conversion functions |

> These functions are Frame based signal processing functions.
