My audio files (.wav) are converted to MFCC (.mfc) by running the sphinx_fe.exe. The input is run thru an FFT and then the output frequencies are input into a MEL filter bank. How many filters are used in this filter bank. Is it possible to vary the number of filters used in this program?
Thank you.
