Sound recognition in Android

Question

I want my Android app to recognize sound. For example I want to know if the sound from microphone is a clapping or knocking or something else.

Do I need to use math,

Answer 1

I realize this is a year old, but I stumbled across it. I'm pretty sure that general, open domain sound recognition is not a solved problem. So, no, you're not going to find any kind of library to do what you want on Android, because such code doesn't exist anywhere yet. If you pick some restricted domain, you could train a classifier to recognize the kinds of sounds your interested in, but that would require lots of math, and lots of examples of each of the potential sounds. It would be pretty cool if the library you wanted existed, but as far as I know, the technology just isn't there yet.
