|  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.
