2@peter or you could keep it always on, which would eat battery up and kill the phone sooner than you could start clapping. – cregox Jan 06 '11 at 13:17

If you're talking about recognizing the sound of a clap, SCListener is a great and easy-to-use class that gives you simple audio levels. Then it's just a question of measuring peaks or even just high values.

2user553239: It's a class of object that listens on the microphone and lets you retrieve the peak and average sound level. A clap will be a high peak that then drops back down to background-noise level. Use of the class is described in the readme at the bottom of the page Luke linked you to. – Peter Hosey Dec 28 '10 at 08:54
