AVAudioRecorder - Continue recording to file after user stops recording by leaving the application and then re-opens it

Question

Can this be done? And if not, how far down towards Core Audio do I need to go (what method of recording should I be using instead)?

I've noticed the behavior of AVAudioRecorder is to overwrite a file if it finds one at the path provided when you request that it record again, so I know that's not going to work. I'm also curious about file format restriction with this idea. Can you effectively resume an AAC or IMA4 encoding (the length of the files I want to record make WAV and probably even Apple Lossless prohibitive)?

Thanks.

Answer 1

As it stands right now, it appears AVAudioRecorder cannot do this.

Answer 2

As Tegeril says, AVAudioRecorder can't do. What you might be able to do though is record as separate files then concatenate using this answer:
