[sdiy] Simple compressor, agc, ?

[Peter Cornell]

Hi Toby

I built a very nice optical compressor which is detailed over at my site :

http://1176neve.tripod.com/id5.html

It might be a bit too subtle in it's present form but can be bade to limit a 
bit more radically with a small mod.

Or else, the SSL 4000 talkback compressor is very much a brickwall 
compressor. Have a look here :

http://www.gyraf.dk/index.html > to Resources & scroll down.
Or even the SSL compressor at the Gyraf site, look in the DIY projects area.

Regards
Peter
