It applies compression to the track it's on, and is controlled by an incoming audio signal (sidechain input). Sidechain compression can be achieved with any compressor that has a sidechain input. Sidechain plugins use volume automation and envelopes to create a sidechain-like effect. What's The Difference Between Sidechain Compression & Sidechain Plugins? You can use sidechain compression for a pumping effect, to duck instruments out of the way, or on dynamic resonance suppression plugins/multiband compressors, to duck certain ranges of the problem the spectrum that is clashing. If you have instruments that are clashing with each other, you can use a sidechain to duck one slightly out of the way, creating space for the other.

Sidechain compression is an extremely useful effect to have for mixing. Volume automation – creating the sidechain effect without compression, often using a sidechain VST.Creating space in specific frequency ranges – using multiband/dynamic resonance suppressors to sidechain problem frequencies.Snare & entire mix – gives a short pocket of space for the Snare to cut through.Vocals and Reverb – providing more clarity for the Vocals.

Vocals and Instruments – ducking the instrumentation out of the vocals creating more space.Pumping effect – for EDM, RnB, Hip Hop & other genres.Kick & Bass – ducking the bass out of the way of the kick to create low end space.Here are some examples of where you can use sidechain compression in a mix:
