Hi there! I am planning to extract the timbre fearture of audio using MFCC function in Matlab. there is 1s silence at the beginingand and the end of the targeted audio(4s in total).The function goes well except for that the silence period also get specific values for each coefficients which I suppose should be 0. I don’t know the reason and resolution for this.
I know that I could just delete the silence area before carring out MFCC, but the 300 audio files I’m going to deal with have different length with each other. Some of them have 0.5s silence period at the end, some have 0.7s, etc.
So I am wondering whether there are better solutions for this problem.

Thanks very much!Hi there!
