Does this gain control occur before or after the compressor if it
is engaged?

Might be more appropriate for a long decay gain control loop to
FOLLOW the compressor (clipper). IIRC, that is the order in most

By the same reasoning, we might obtain improvement to our analog solid

You are absolutely right. While much of the pro-audio equipment is

the expensive of many analog stages, we are seeing requests for adding

That is, a way to control analog dynamic range at the
input of the RF Clipper section of the DSP audio chain.

Never heard of him.
The best way to fix audio ambient noise issues is through
your environment's acoustics instead of fixing it in the
mix with processing and gating.
and the neighbors on either side of your
frequency will appreciate your efforts.

And do remember, more compression brings up background noise between
words by the amount of the compression value. Hence with 10 dB of
compression, a background noise level that would normally produce and
