Default Simple compressor

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?

Impedance varies with frequency, use impedance plots of your drivers and make crossover calculations using the actual impedance of the driver at the crossover frequency

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?
