I agree with Larry's general point here. "perfect" pitch isn't so useful as relative pitching. An absolute pitch without context isn't strictly speaking musical information. It also generally assumes that "middle" A = 440Hz and equal temperament are somehow "right" and good, I find it somewhat discordant. The important point is that you would need some sort of pitch and timbre reference in order to make sense of the incoming information. My first thought would be to see what pd can do, but I'm very much a beginner with it. cheers tim hall
