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.

       Using  the  default  parameters,  the  filter  coefficients  will be computed according to
