2 aubiomfcc - a command line tool to compute Mel-Frequency Cepstrum Coefficients
7 aubiomfcc [[-i] source]
8 [-r rate] [-B win] [-H hop]
13 aubiomfcc compute the Mel-Frequency Cepstrum Coefficients (MFCC).
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.
19 When started with an input source (-i/--input), the coefficients are given on
20 the console, prefixed by their timestamps in seconds.
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.
27 -i, --input source Run analysis on this audio file. Most uncompressed and
28 compressed are supported, depending on how aubio was built.
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.
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.
37 -H, --hopsize hop The number of samples between two consecutive analysis.
40 -h, --help Print a short help message and exit.
42 -v, --verbose Be verbose.
46 Using the default parameters, the filter coefficients will be computed
47 according to Malcolm Slaney's Auditory Toolbox, available at the following
