Simple compressor

[PeteMcK]

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?

Hi,

i know this is an old thread, but did you get this working ?

Thanks,

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?
