I would like to be able to detect a clapping sound. Being pretty new to any form of sound recognition, is there simple any way to do this? If not, any good resources for C# sound recognition/detection?
My goal is to automate a clients media center with some basic clap-based controls.
There was a similar question asked in the past:
Given an audio stream, find when a door slams (sound pressure level calculation?)
Although the question was not specific to C#, it does have some ideas for algorithms to use. (Disclosure: Yes, I did answer that question.)
Not sure whether this will be of any help, but still: MERL - Sound Recognition. Or better yet, Clap detection, with microphone.
I wouldnt focus on the language as such, but on the algorithm.
What characteristics of a sound allow you to identify it as a clap? Duration? Intensity? Variation of intensity over time?
Once you've got an algorithm, then decide the best way to implement it.
It seems like a problem you can solve using a so called Principal Component Analysis. Try to google it. Also other solutions for the famous Cocktail Party Problem may help. But I am sure there are already some libraries out there.
Check out Audio Zone Trigger for $25 it looks like it will do exactly what you want.
