Write .wav file , from buffer ?

Asked by I Made on 15 Mar 2013

How to convert back after using buffer function on a signal, e.g i have code

    f=wavread('example.wav',native);
    leftchanel=f(1:size(f),1);
    rightchanel=f(1:size(f),2);
    segment=buffer(leftchanel,512);

how do i convert back "segment" into "leftchanel" ? then what to do to combine the "leftchanel" and "rightchanel" back and rewrite it back to .wav file again? because :

    wavwrite(y,filename);

only above write to wav code i can find, there is no chanel parameter in it? am i supposed to combine "rightchanel" and "leftchanel" into "f" first?

I actually figured it out myself a little different using for loop to combine it, but yours work great too. Thanks :D
