IPhone App to record Any Audio that's playing
===

I'm looking for an app in the app store which may not exist but I certainly have not had success finding which is I'd like to record any audio that's being played on my iphone no matter the source.  I want to record what the IPhone sound card is playing at any time but not interrupt any app that's the player playing it (browser, another iphone app, whatever is playing the stream).

Anyone find an app that does specifically this?
