AUBIOMFCC(1) aubio User's manual AUBIOMFCC(1)NAMEaubiomfcc - a command line tool to compute Mel-frequency Cepstrum Coef‐
ficients
SYNOPSISaubiomfcc source
aubiomfcc [[-i] source]
[-r rate] [-B win] [-H hop]
[-v] [-h]
DESCRIPTIONaubiomfcc compute the Mel Frequency Cepstrum Coefficients (MFCC).
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 com‐
pressed 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.
-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 Auditory Toolbox, available at the fol‐
lowing url:
