Analyzing Audio Data

Name: Anonymous 2007-03-09 19:28 ID:y4On30GM

I'm working on a little project in my spare time. My aim is to analyze tiny chunks of audio data in near-real-time and to use the data in an application (lol game). I have some knowledge of audio but can't think of ways to analyze the data aside from discerning the different wavelengths in a given unit of audio. While it would work, there's no guarantee that there will be enough different wavelengths to provide enough variables.

for tl;dr
How the fuck do I get a few dozen variables from a millsecond or less of audio without implementing an easily abused system?

Spectrum analysis, and some kind of memory from previous chunks. For example, group variables in sets of 12; in each step, you shift them 12 by 12, and fill the new 12 with new spectrum analysis. Variables could be intensity values for different frequencies.
