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 When started with an input source (-i/--input), the coefficients are given on
16 the console, prefixed by their timestamps in seconds.
20 This program follows the usual GNU command line syntax, with long options
21 starting with two dashes (--). A summary of options is included below.
23 -i, --input source Run analysis on this audio file. Most uncompressed and
24 compressed are supported, depending on how aubio was built.
26 -r, --samplerate rate Fetch the input source, resampled at the given
27 sampling rate. The rate should be specified in Hertz as an integer. If 0,
28 the sampling rate of the original source will be used. Defaults to 0.
30 -B, --bufsize win The size of the buffer to analyze, that is the length
31 of the window used for spectral and temporal computations. Defaults to 512.
33 -H, --hopsize hop The number of samples between two consecutive analysis.
36 -h, --help Print a short help message and exit.
38 -v, --verbose Be verbose.
42 Using the default parameters, the filter coefficients will be computed
43 according to Malcolm Slaney's Auditory Toolbox, available at the following
