Sound Pattern Recognition in Objective C / C (Mac)

Is there any C or Objective-C library that I can use to detect sound patterns on the Mac (e.g. clap of开发者_StackOverflow hands)?

Well, if you use CoreAudio, it has a few libraries hidden inside that do some pattern recognition.

But in any case, if you have no previous samples to go by, I would recommend something where you sample a clap, and then compare the questionable samples with your samples, allowing some deviation in both the x and y, and then add any successful detections to your sample list and decrease the allowable deviation.

This is a very slow method, but, in my experience, one of the most reliable for recognizing any sound, especially with a large number of starting samples.
