By default, 13 + coefficents 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. + + -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 following + url: + + http://cobweb.ecn.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). + +AUTHOR + + This manual page was written by Paul Brossier <piem@aubio.org>.
