I have to do cross correlation of two audio file to prove they are similar. I have done FFT of two audio files and have the power spectrum value of both the audio file in a separate array.how should i proceed further to do cross correlation to prove they are similar.Any basic ideas will be helpful for me to learn and apply it.Thanks.
