Anyone familar with DSP knows about convolution, even if it's just related to it's uses for reverb. It seems like it's slowly being used for many different purposes now from reverb to effects processing. Well, one of my teachers claims to have invented the use of convolution for audio in his thesis and was approached by Yamaha (I think it was) to use it in one of their products. I have been looking, but can't find, who discovered the audio use of convolution? What was is it's first commerical use? I believe him, but I want to confirm it, so I won't mention his name . . .
