Simple compressor

PeteMcK · 25th August 2009, 01:12 AM

I once built a simple compressor from Elektor, lost the schematic aeons ago.
It looked something like the attached pic.
Would it work as drawn, and if so, any suggestions for component values?

I think for -ve DC it works, the diode is inverted.
As the cap voltage increases the FET turns off, increasing the attenuation.

But what happens with +DC and more importantly with an AC signal?
