Given a Mel filter bank description, bin the FFT coefficients to compute the output of the filters.

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.
