whizkid said:What I want to do, is say you play an A note on the piano. The microphone will pick this up, and the circuit will be able to output 440Hz or whatever. That's the basics of it....

hotwaterwizard said:Where does it say he needs to know what frequency it is?
I read it as he needs to put out the same frequency.
