Isn't it strange that all those mathematicians, physicists, and engineers have been going around using Fourier analysis for the last 150 years? Gee, I guess they were too stupid to realize that sounds are "a combination of many frequencies all occurring at the same time", and that invalidates everything they were doing! What a revelation! Sorry Patrick, but that just ain't the way it works. In fact, as most of us learned in high school, any sound can be decomposed into a sum of pure tones, which add *linearly*, period, end of story. If the frequency response of an amp and speakers is flat, so is the response to music. (We could talk about distortion, but that's not what you said.) Now, I don't mind if you don't understand that - I don't really care at all, actually. But when you go around spreading false information in order to hawk your products, that kind of gets under my skin.
