Well, it might be possible, but you would need an adapter that allows for three, and personally I have yet to see one that works with more than two. Also you would need an app for this, as a regular recording app will just record it all together. Which, in the end, would not be the best idea if you are wanting to be able to alter any specifics. That would need a way to have them separated/tracks. If not, then it may work. I would still consider looking into an app that is for music recording specifically rather than using the phones general recording app.
