What Is Sidechain Compression? And How To Use It

What Is Sidechain Compression? And How To Use It

by Nick Messitte, iZotope Contributor August 20, 2021

In mixing, you may have come across a form of compression called “sidechain compression” and had no idea what it meant. What is it and why is it useful? In this piece, we’re going to define sidechain compression for you in simple terms. We’ll show you some common uses, and point you to some examples of sidechain compression in the wild, so you can train your ears to recognize sidechain compression in action.

This discussion points out the detection circuits for the compressor in Neutron. Recently posted about the detection circuit in Ozone 9 as well.

Good things to know.

iZotope Ozone Pro is one of the most popular and powerful mastering plug-ins in the world. It’s been around for almost 20 years, but whether you’re new to it or even a longtime power-user, there are features in the tool that you probably don’t even know about.

The detection filter is important to know about.

Dynamics – Ozone 9 Help Documentation

The Dynamics module can be used to shape the dynamics of your master, with up to four bands of analog-modeled compression, limiting, and expansion.

11 Creative Sidechain Compression Techniques

My friend and fellow contributor Phillip Nichols has already covered some common applications for sidechain compression. In this article, we’re going to explore some esoteric, creative, and all-around fun uses for the practice. Many of these tactics will involve the use of a dummy track, so let’s define that term quickly:

Some people refer to “mixing tricks” but are they really tricks? When is a technique just a technique? Julian looks at some common examples and decides.

I put an EQ as the first insert on my reverb AUX channels. When I insert reverbs I try to make sure that I adjust the filters that are built in to most of my reverbs. I think it’s better to be able to “see” the filter on the AUX channels.

My colleague Steve DeMott did an article on 2-Buss compression recently. He describes various practical compression techniques and approaches when applying compression to a full mix on the stereo bus.  In this video, I take some of his ideas and develop them using Logic’s powerful and flexible built-in compressor plug-in. There is a lot more to this plug-in than initially meets the eye, especially when it comes to “glue” style bus processing.
