Hi
i have recorded my voice from two mics at the same time in two different tracks in the same file. Now inorder to correlate them, i have to read them separately from the tracks. could someone please tell me how to do that in matlab?
thanks in advance

You can use software like audacity to split the single audio file with two into two audio files. Then you can import them into matlab separately and correlate.
Not aware of MATLAB's audio editing capabilities :).

One thing you could try while recording from now on is pan 1 track to the left and the other to the right so that it will be easy to split it later.

I assume this is similar to a stereo signal. If that's the case, then you can still use wavread to read in the file.
[y,fs] = wavread(FILENAME)
The variable y in this case should have two columns and each one corresponds to a track.

But that will retrieve all of the tracks simultaneously, which (for whatever reason) Padma does not wish to do.
There is, as far as I know, no provided mechanism to return one track at a time.
