AUBIOMFCC(1) aubio User's manual AUBIOMFCC(1) NAME aubiomfcc - a command line tool to compute Mel-Frequency Cepstrum Coeffi- cients SYNOPSIS aubiomfcc source aubiomfcc [[-i] source] [-r rate] [-B win] [-H hop] [-T time-format] [-v] [-h] DESCRIPTION aubiomfcc compute the Mel-Frequency Cepstrum Coefficients (MFCC). MFCCs are coefficients that make up for the mel-frequency spectrum, a rep- resentation of the short-term power spectrum of a sound. By default, 13 co- efficients 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. 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. -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. REFERENCES Using the default parameters, the filter coefficients will be computed ac- cording to Malcolm Slaney's Auditory Toolbox, available at the following url: https://engineering.purdue.edu/~malcolm/interval/1998-010/ (see file mfcc.m) SEE ALSO aubioonset(1), aubiopitch(1), aubiotrack(1), aubionotes(1), aubioquiet(1), and aubiocut(1).
