I wrote a program that analysis a stereo voice file when I am trying to analysis a new voice file I have found error due to Mono file.
How can I change a stereo voice file to mono ?

If the stereo voice file is Nx2, then just extract 1 column
X = randn(2e4,2);
Y = X(:,1);

Or, since he already has his stereo analysis program written and done, just use repmat() to convert the new "Mono file" into a stereo file. This would make sure it doesn't break anything in his existing program that depends on the signal being stereo.

I have to analysis different voice files with one program,can I write something in the codes that I don't want to change the codes every time?
