Get correlation value between two .wav files

I need to compare the similarity between two audio files saved in .wav format. For that how can I take the correlation between two .wav files as a percentage in matlab?

Did you get your answer?? I also needed that

Use audioread to read in the two wav files. Make sure they are at the same sampling rate (otherwise adjust one to match the other). If you'd like the correlation between those two sample data, use corrcoef().

[y,Fs] = audioread(filename)

R = corrcoef(A,B)
