iPhone: Access voice memos programmatically

I am writing an app that plays some simple voices and sounds using AVAudioPlayer. However, in order to really make the app "killer", it would need to access the users' own voice memos so that they can play back their own memos using my app (my app actually does something cool with the memos, so there is actually a point to using it! :p).

I haven't been able to find any documentation on this, nor any guides (here or out in the cloud).

Is this even possible or do I have to add a little guide asking the user to record a sound, import to iTunes, sync with device, then access it via the music library? Or perhaps another solution of recording in-app?
