Documentation

Calculate the (log) energy (or power) in each channel of a Mel scale filter bank for a frame of speech. The filters are triangular, are evenly spaced and are all of equal width, on a Mel scale. The upper and lower cutoffs of each filter are at the centre frequencies of the adjacent filters. The Mel scale is described under Hz2Mel.
