iPhone app sound recognition?

Question

I'm trying to get an app to record microphone input, and respond to certain sounds. These sounds would be pre-recorded and played on a different device-- like website or TV.

So I'm guessing it'd be a matter of comparing the audio data. Any idea about a good place to get started?

Answer 1

Recording sound should be easy. Check the Speak Here code sample from apple. For comparing two sound files, see this question.
