**NAME**

aubiomfcc- a command line tool to compute Mel-Frequency Cepstrum Coefficients

**SYNOPSIS**

aubiomfccsourceaubiomfcc[[-i]source] [-rrate] [-Bwin] [-Hhop] [-Ttime-format] [-v] [-h]

**DESCRIPTION**

aubiomfcccompute 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 inputsource(-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,--inputsourceRun analysis on this audio file. Most uncompressed and compressed are supported, depending on how aubio was built.-r,--sampleraterateFetch the inputsource, resampled at the given samplingrate. Therateshould be specified in Hertz as an integer. If 0, the samplingrateof the originalsourcewill be used. Defaults to 0.-B,--bufsizewinThe size of the buffer to analyze, that is the length of the window used for spectral and temporal computations. Defaults to 512.-H,--hopsizehopThe number of samples between two consecutive analysis. Defaults to 256.-T,--timeformatformatSet time format (samples, ms, seconds). Defaults to seconds.-h,--helpPrint a short help message and exit.-v,--verboseBe verbose.

**REFERENCES**

Using the default parameters, the filter coefficients will be computed according to Malcolm Slaney's Auditory Toolbox, available at the following url: https://engineering.purdue.edu/~malcolm/interval/1998-010/ (see file mfcc.m)
