Hi Micheal, Thanks again,
I now have it recording in PCM format from the mic and saving it to the sd card and then playing it back through the ear piece. So I just have to look into how to into piping the AudioRecord straight into the AuditTrack. So with the AudioRecord instead of creating a file to save to what should I look into doing? And with the AudioTrack, instead of looking for a file to read in what should I look into doing?
