Can you name names? Google isn’t hitting.
The usual “wide” has two knees, one just above soft and one at loud. Maybe they count knees?
The next step past a simple compressor is separate compression for lows and highs. Allows less compromise with attack/release times.This was state of the art in radio broadcast, oh, 45 years ago. I have the impression that recent top-tier HA processors “can” compress each of 20 frequency bands separately (though probably linked with a big Slinky so bands don’t pop in and out).
If they are lower-tech makers, it may mean as much as Dual Exhaust on cars. You can put 1,000HP (and more) through a single exhaust, but dual pipes under the bumper lets everybody know you got a hot ride.
But if you got a link I will look at it.
