# aubiomfcc man page

**aubiomfcc** — a command line tool to compute Mel-frequency Cepstrum Coefficients

## Synopsis

**aubiomfcc** *source*
**aubiomfcc** [[**-i**] *source*]
[**-r** *rate*] [**-B** *win*] [**-H** *hop*]
[**-v**] [**-h**]

## Description

**aubiomfcc** 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 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 256.
**-h, --help**- Print a short help message and exit.
**-v, --verbose**- Be verbose.

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