I have this app that plays binaural waves underneath background noise of a white noise of some sort. I'm trying to get it so I can have the waves playing in the background of my ipod. I know it's possible with this other binaural wave app, but it also plays some nonsense in addition to the wave. I'm trying to get the app that I have to be able to play in the background while my ipod is going. Is that possible? Do I need to edit a plist of some sort? I tried backgrounder, but no dice.

I have: Iphone 3gs on 4.0.1
