aubiomfcc - a command line tool to compute Mel-Frequency Cepstrum
aubiomfcc [[-i] source]
[-r rate] [-B win] [-H hop]
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.
This program follows the usual GNU command line syntax, with long options
starting with two dashes (--). A summary of options is included below.
Using the default parameters, the filter coefficients will be computed according
to Malcolm Slaney's Auditory Toolbox, available at the following url:
- -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
- -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.
