## void fft2fbank | ## (const EST_FVector &fft_frame, EST_FVector &fbank_vec, const float Hz_per_fft_coeff, const EST_FVector &mel_fbank_frequencies)

## Documentation

> Given a Mel filter bank description, bin the FFT coefficients to compute the output of the filters. The first and last elements of `mel_fbank_frequencies` define the lower and upper bound of the first and last filters respectively and the intervening elements give the filter centre frequencies. That is, `mel_fbank_frequencies` has two more elements than `fbank_vec`.
