aubiomfcc compute the Mel-Frequency Cepstrum Coefficients (MFCC).
MFCCs are coefficients that make up for the mel-frequency spectrum, a representation of the short-term power spectrum of a sound. By default, 13 coefficents are computed using 40 filters.
When started with an input source (-i/--input), the coefficients are given on the console, prefixed by their timestamps in seconds.
This program follows the usual GNU command line syntax, with long options starting with two dashes (--). A summary of options is included below.
Using the default parameters, the filter coefficients will be computed according to Malcolm Slaney's Auditory Toolbox, available at the following url:

aubioonset(1), aubiopitch(1), aubiotrack(1), aubionotes(1), aubioquiet(1), and aubiocut(1).
