NAME
       aubiomfcc - a command line tool to compute Mel-Frequency	Cepstrum Coef-
       ficients

SYNOPSIS
       aubiomfcc source
       aubiomfcc [[-i] source]
		 [-r rate] [-B win] [-H	hop]
		 [-T time-format]
		 [-v] [-h]

DESCRIPTION
       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.

OPTIONS
       This  program  follows the usual	GNU command line syntax, with long op-
       tions starting with two dashes (--). A summary of options  is  included
       below.

       -i, --input source
	      Run  analysis  on	 this  audio  file. Most uncompressed and com-
	      pressed are supported, depending on how aubio was	built.

       -r, --samplerate	rate
	      Fetch the	input source, resampled	at the	given  sampling	 rate.
	      The  rate	 should	be specified in	Hertz as an integer. If	0, the
	      sampling rate of the original source will	be used.  Defaults  to
	      0.

       -B, --bufsize win
	      The  size	 of  the  buffer to analyze, that is the length	of the
	      window used for spectral and temporal computations. Defaults  to
	      512.

       -H, --hopsize hop
	      The  number  of  samples	between	two consecutive	analysis.  De-
	      faults to	256.

       -T, --timeformat	format
	      Set time format (samples,	ms, seconds). Defaults to seconds.

       -h, --help
	      Print a short help message and exit.

       -v, --verbose
	      Be verbose.

REFERENCES
       Using the default parameters, the filter	coefficients will be  computed
       according  to  Malcolm Slaney's Auditory	Toolbox, available at the fol-
       lowing url:

       mfcc.m)
