11DESCRIPTION
12
13  aubiomfcc compute the Mel-Frequency Cepstrum Coefficients (MFCC).
14
15  MFCCs are coefficients that make up for the mel-frequency spectrum, a
16  representation of the short-term power spectrum of a sound. By default, 13
17  coefficents are computed using 40 filters.
18
19  When started with an input source (-i/--input), the coefficients are given on
20  the console, prefixed by their timestamps in seconds.
21
22OPTIONS
23
24  This program follows the usual GNU command line syntax, with long options
25  starting with two dashes (--). A summary of options is included below.
26
27  -i, --input source  Run analysis on this audio file. Most uncompressed and
28  compressed are supported, depending on how aubio was built.
29
30  -r, --samplerate rate  Fetch the input source, resampled at the given
31  sampling rate. The rate should be specified in Hertz as an integer. If 0,
32  the sampling rate of the original source will be used. Defaults to 0.
33
34  -B, --bufsize win  The size of the buffer to analyze, that is the length
35  of the window used for spectral and temporal computations. Defaults to 512.
36
37  -H, --hopsize hop  The number of samples between two consecutive analysis.
38  Defaults to 256.
39
40  -h, --help  Print a short help message and exit.
41
42  -v, --verbose  Be verbose.
43
44REFERENCES

46  Using the default parameters, the filter coefficients will be computed
47  according to Malcolm Slaney's Auditory Toolbox, available at the following
