soundA = Path_of_soundA.wav;
soundB = Path_of_soundB.wav; %%soundA and soundB have not the same length
[C1,lag1] = xcorr(soundA,soundB);
avv = max(xcorr(soundA,soundB));
fprintf(['\n avv = ', num2str(avv)]);  %%I want something between 0 and 1. Something that I 
%%know the limit

You can try

xcorr(soundA,soundB,'coeff')

It doesn't work.

It works only if soundA and soundB have the same length.
