At the moment I am experimenting with an opto compressor.
My prototype sounds good, especially when the ratio is not very high (say 2:1 and the threshold is low).
But...the problem is that my opto compressor is slow. And this is probably why it sounds pretty good!
I used VTL5C1 and VTL5C2 vactrols, without a very big audible difference.
Now, looking at the specifications of the vactrols I use, I see reaction times of a couple of milliseconds.
But some manufacturers of opto compressors claim attack times of 0.5 mSec!
How do they do this? As far as i know the cadmium sulfide cell usually needs time to get to the new resistance value.
Who knows more about this subject?
