NAME

       aubiomfcc - a command line tool to compute Mel-Frequency Cepstrum Coefficients

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 coefficients 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 options starting with two dashes (--).
       A summary of options is included below.

       -i, --input source
              Run analysis on this audio file. Most uncompressed and compressed 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.  Defaults 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
