Re: .wav files.
Sorry, probably should have been more specific.
What I am trying to attempt is to overlay two or more wave tracks for a music recording and playback project I am coding.
For example a user would be able to record a guitar line on one track, vocals on another, bass on a third and drums (in theory!) on a forth and then combine these wavs to form one wave file so that the user can burn their creation to a cd.
Hope this clears up my intentions!
