I have a block of audio and I have performed an FFT on it. Now what I want to do is convert this FFT into a set of MFCCs, however while I know I need to do something with weighting the FFT samples based upon a set f triangular filters I haven't really got a clue what this involves.
Can anyone go into some good detail on it? If you are going to give me a matlab example please explain each step well as matlab allows you to cut quite a few corners and I'm trying to implement MFCC extraction on iPhone.
