What Is Side Chain Compression?
When people refer to side chain compression they usually mean external side chain compression. All compression uses a side chain. the side chain is the signal which is being monitored by the detector i.e. the signal which is controlling the gain reduction. This is usually the signal, which is having the gain reduction applied to it but it doesn’t have to be. When an external signal is controlling the compressor it is referred to as side chain compression..
In this simple example an Avid Channel Strip is reducing the gain each time the kick drum hits, giving the familiar, rather over-used pumping effect. Side chain compression can be used much more subtly than this but in all cases the method is the same.
