So if you give a computer a list of all the characteristics of the letter 'A' (a dubious concept in itself) it's no problem getting it to recognize various A's? Tell that to the visual perception people! I kinda doubt that it's purely processing power. Maybe recognizing individual songs could be done by some kind of wave-form pattern matching but this obviously wouldn't work for identifying the type of music. How do you list all the "types" of music? I don't think you really can. I mean we classify things like music with new concepts all the time. e.g. "Gee that song has sort of a Jetson's feel to it" etc. I'm sure the original poster didn't mean simply inputting a song and having the computer spit out one of rap, pop, rock, jazz, classical, etc. This wouldn't satisfy me at all. (Although I imagine it's a pretty difficult problem.) However if the program were able to take a song like Faith No More's Epic and tell me that it's an interesting blend of contemporary rock styles combining rap, thrash, and a funk sound; I'd be pretty impressed. Perception definitely cuts to the core of intelligence in my book. Chris Weyand, weyand@cs.uoregon.edu weyand@csli.stanford.edu
