[aubio-user] Different nubmber componets in MFCC vector

[Paul Brossier]

Hi Malintha,

For now the number of coefficients and the number of filters are
hard-coded in examples/aubiomfcc.c:

uint_t n_filters = 40;
uint_t n_coefs = 13;

These defaults correspond to Malcom Slaney's Auditory Toolbox:

For now you can just change that number and recompile. I will try to add
a an option to pass it from the command line.

Best, Paul
