yes I did, this is my code..
clear all;
clc;
[A, Fs] = wavread('D:\TESTING SOFTWARE\matlab\1a.wav');
[B, Fs] = wavread('D:\TESTING SOFTWARE\matlab\1aa.wav');
maxlags = length(B);
[c,lag]=xcorr(A,B,maxlags);
I have taken one wave length from each 1a.wav and 1aa.wav signals. In here length(B) was larger than length(A) so no need to resample and xcorr will zero padded to A data. and then how can judge by looking the data whether those are approximately same wave shapes. please help..
