Frame based filter bank and cepstral analysis

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

These functions are Frame based signal processing functions.
