My goal is to create program on octave that loads audio file (wav, flac), calculates its mfcc features and serve them as output. The problem is that I do not have much experience with octave and cannot get octave load the audio file and that is why I am not sure if the extraction algorithms is correct. Is there simple way of loading the file and getting its features?
You can run mfcc code from RASTAMAT in octave, you only need to fix few things, the fixed version is available for download here.
The changes are to properly set windows in powspec.m
WINDOW = hanning(winpts);
and to fix the bug in specgram function which is not compatible with Matlab.
