Microphone question in iPhone SDK

Question

I am trying to do an app, to where when it launches, it will detect audio, and then play it back automatically. NO BUTTONS, nothing to press. Just a picture of something then, it listens for audio, then plays it back. Similar to the Talking Carl app in the App Store. Any ideas/help? Would appreciate it, if i could use the code with IB.

Apple has released a document named Audio & Video Coding How-To's. I’d suggest you start with “How do I record audio from the built-in microphone?”, read “How do I record and play back audio at the same time?”, and, finally, check out the aurioTouch project. Good luck!
