compress opcode

	I am using the compress opcode. I have noticed that when the sidechained signal (acsig) is 0, it mutes the carrier signal (aasig). I discovered this by initalising an a-rate signal to 0 and using it as acsig. If I instead init acsig to 1, it lets the audio through. Why is this? Surely it should be the other way round.

	I've just noticed that it works with a very low signal. So I'm guessing there is some kind of exponential/logorithmic maths going on behind the scenes that doesn't work with 0 carrier input. Could that be right? On Wed, Dec 16, 2015 at 3:34 PM, Peter Burgess <pete.soundtechnician@gmail.com> wrote: I am using the compress opcode.
