Sidechain

In beatmaking and music production, a sidechain is a technique where the output of one audio track or signal is used to control or influence the behavior of another track or effect. This technique is commonly used to create rhythmic pumping effects, improve mix clarity, or add dynamic interest to a track. Here’s a more detailed explanation:

What is Sidechaining?

Sidechaining is a process where an audio signal (the “sidechain input”) is used to trigger or modulate an effect on another audio track. The most common use of sidechaining in beatmaking is with a compressor, but it can also be applied to other effects like gates, EQs, or even volume automation.

Common Applications in Beatmaking

1. Sidechain Compression

This is the most well-known use of sidechaining in modern music production:

• Typically, the kick drum is used as the sidechain input.
• When the kick hits, it causes a compressor on another track (often the bass or synth) to reduce its volume momentarily.
• This creates a pumping effect that’s characteristic of many electronic dance music genres.

2. Creating Space in the Mix

• Sidechaining can help create space for important elements in a dense mix.
• For example, ducking the volume of a pad or background element when the vocal comes in.

3. Rhythmic Effects

• Producers use sidechaining to create interesting rhythmic patterns and grooves.
• This can be done by sidechaining various elements to different rhythm sources.

4. Gating and Keying

• A gate effect can be sidechained to open only when a specific sound plays.
• This technique is often used for creative sound design or to tighten up rhythmic elements.

Benefits of Sidechaining

1. Improves mix clarity by reducing frequency masking
2. Adds groove and movement to static sounds
3. Creates a sense of cohesion between different elements of a track
4. Allows for creative sound design possibilities

Sidechaining has become an essential technique in modern music production, particularly in electronic genres, but it’s also used across many other styles to create dynamic and interesting mixes.
