I believe the words "Side-chain" aren't used correctly here. The way it's defined right now is what I would call "Ducking" (there's a quick note about this alternate name). The page goes on to define "Parallel compression" as what I would call a "Side-chain effect." This page backs up my definition of Side-Chain:[1]I would define the three terms like this:
Side-Chain - using two copies of the same signal (only one with an effect applied), and mixing the two together.
Ducking - Using the amplitude of one signal to control the gain of another. The example of having background music fade out while someone is talking and fade back in when they finish talking is perfect.
Is it really necessary? I don't think it adds anything to the article and just has the ability to offend, but as a newbie to editing Wikipedia, I'll leave it to this article's regulars. 65.107.212.130 (talk) 22:23, 14 January 2008 (UTC)
I laughed when I read that, and it's a very apt description. Keep it. —Preceding unsigned comment added by 75.164.238.106 (talk) 01:02, 31 May 2009 (UTC)
This article is a good introduction to the topic, but it could use some editing. For example, its definition of a compressor would more-accurately describe a limiter.
