I'm bored and I want something to happen when I snap my fingers or clap my hands. I've been googling for some kind of sound recognition software, but all I can find is speech recognition.
Any idea what I should google for? Or if someone knows a software that can run commands on certain recognized sound.
Im no expert, never done this before, but cant you record a sound, and then check to see if the mic picks up a simuler sound?
There must be some libarys out there for this kind of thing to...

Looking up, he asks the Lord...
"God, what does a million years mean to you?"
The Lord replies, "A minute."

The Lord replies, "A penny."
There are some good explanations floating around of how speech recognition uses pitch and frequency to match up to known phonemes. However, this doesn't help as they don't explain the process of sampling and capturing the sounds in the first place. Searching "sound recognition open source" brought me to the above framework, and it looks like most of them like to refer to themselves as "audio recognition"... so, you'd probably have better luck hunting down information with that.

Do you want something to happen only when you clap your hands or something like that, or is any sound good enough? Would be quite annoying when talking though, but if you wouldn't mind, you could just use an analog 0-5V sound sensor. You can get those at many places and they're not that expensive at all. The ones we have at our school have a measuring range between -45 and 45 Pa, where p0 = 2.5x10^-5 Pa. Can be used for measuring decibels, speed of sound, short pressure pulses, etc. Perhaps you could write your own software that analyses all the sounds and searches for certain patterns which correspond with a certain sound.
