I looked in the Core Audio docs and found a that there's a pre-built audio unit,
kAudioUnitSubType_TimePitch, which I think will work. I just hope its available on the iPhone and can be used to alter the playback speed of a track in real time...

The way I see it, playback rate change is the same as speed/tempo and
pitch change, unless you are talking about doing something more
elaborate like time stretching and pitch shifting.
