How do I record audio on iPhone with AVAudioRecorder?

For Playing the sound you have option to use AVAudioRecorder.

Hope this helps.

The best way to do it - and I am talking from painful experience here - is with the RemoteIO audio unit. You can also do it with AudioQueue, but it has a higher latency, and the queue type approach becomes very problematic.

So, I think that they are really different tools for different jobs. Note that you won't play a sound file as such. You will play the contents of a buffer held in memory. As long as the buffer is not too large, this should not be an issue.

So, going with RemoteIO, you will find this blog and tutorial very useful. It includes code samples.
