High School Physics......

I feel like I may need a high school physics book but can someone point me to a resource on the web (or a good book) on the basics of sound, the wavform, frequencies, amplitude, etc.....?

Some of the things I wonder about... When I look close at a wav in Soundforge, just what am I looking at? I believe the frequency is determined by how many times it crosses above the line to below in a second. How are all the instruments, or frequencies I guess, represented in a single line? How do you determine what sounds are at what frequencies if you want to 'highten' or 'reduce' with an equalizer?

Any help would be appreciated. (remember, you promised not to laugh.....)
 
As simply as I can manage; you're looking at a time vs. amplitude graph across <all> frequencies. So the main sort of information you can get out of this is 'scrub' info to help you locate a point in a recording. Sure there is other info extractable from this picture of the wave. Compressed .wav files have a particular look to them, etc.
 
Thanks for the info so far. I've checked out www.silcom.com/~aludwig and, getting several pages in, looks like a great primer on sound. Just what I was looking for. Lot's more reading to do there. I just hope he takes it into the world of digial Wavs at some point. Anyone have more info on that aspect, I'm still interested.

Thanks again.
