audio event detection

Question

Is there an (easy?) way to detect an audio event like a finger snap or hand clap with the Kinect Audio SDK?

Answer 1

There is no automated way to identify a finger snap or a hand clap.  The Kinect Audio SDK will let you get access to the underlying audio data, but you would need to do your own processing to recognize these sounds. 

If you're just looking for sharp percussive sounds, you could just look for "edges" in the audio data where it goes from relatively quiet to relatively loud very quickly.  However, this would not distinguish between loud percussive events.  (For example, it would be hard to distinguish between a finger snap and hitting a keyboard key loudly).

Can you share a little bit about what your scenario is? 

Answer 2

thanks. That's what I figured.

I'm working on a gestural interface. Keyboard interference is unlikely. Music or ambient noise is more probable, but would, in my mind, be tolerable interference.
