Envelope follower synth

Here is a little digital instrument for you which combines concepts we have learned early in the course about synthesis with our recordings. What the program does, is transfer the amplitude ie. loudness.of a field recordings to the pitch of a synthesizer. Can you still recognize the original sound? Can make a copy of the program and use your own recordings to drive the sound? Could you imagine some other computer program which takes data from one source and uses it to generate something new in some other context?
