[edit]I don't agree with merging this, as it would be useful to have a full technical description on the page like the one that appears in one of the references that was removed by a previous edit. 203.144.32.165 03:55, 26 January 2007 (UTC)
Does parallell compression have any other effect, than reducing the ratio of the compressor used? 80.98.84.149 17:06, 22 May 2007 (UTC)
Parallel compression doesn't reduce the RATIO of the compressor used, for starters. What it does is keeps a similar ratio while minimally impacting the sound quality. Quite a fun little trick, that. Fun for mastering. And no, we shouldn't merge it. We need someone who really knows their stuff in this regard to expand this into a tutorial, since it is a useful tool not likely to soon become a unified device.
The question above was mine. What I was thinking about:
If we add the dry signal:
To a compressor that looks like this:

Wouldn't we get a compressor that looks like this?

Parallel compression does not keep the same ratio - the combination of the direct path and the compressed path give generate a derived ratio (transfer characteristic) that is always less than that set on the compressor. I'd be willing to expand this article into something with a lot more detail.
