I am looking to record and save a music/song file with one or more audio track(s) let's say a max of two tracks playing simultaneously while recording my vocals via the headset or the microphone. The finished product will be a single song file(mp3 or other format).

Also, the code should have the ability to filter out outside noise/interferance and add basic effects.

Appreciate any and all Xcode help!
