Sidechaining is a popular audio mixing technique used in music production to create space and dynamics between instruments. If you’ve ever heard that classic pumping effect in EDM, hip-hop, or pop tracks, that’s sidechaining in action.
Learning how to sidechain allows you to control the volume of one track based on the level of another. This helps important elements, like vocals or kick drums, stand out while keeping your mix clean and professional.
What Is Sidechain Compression?
Sidechain compression is a process where the level of one audio signal (the “sidechain input”) controls the compression applied to another signal.
Example:
- You have a bassline and a kick drum.
- You set the bassline to be sidechained to the kick drum.
- Every time the kick hits, the bass volume ducks slightly, letting the kick punch through the mix.
This technique is commonly used for:
- Making kick drums more prominent
- Creating that “pumping” effect in electronic music
- Preventing competing frequencies from clashing
How to Sidechain in Your DAW
Here’s a simple step-by-step guide for how to sidechain in most digital audio workstations (DAWs):
1. Insert a Compressor on the Track You Want to Duck
- Usually, this is the bassline, pad, or synth.
2. Enable Sidechain Input
- Most compressors have a sidechain or key input option.
- Choose the track that will trigger the compression (like the kick drum).
3. Adjust Compressor Settings
- Threshold: Set how loud the trigger signal must be before compression starts.
- Ratio: Determines how much the volume is reduced.
- Attack: Controls how quickly the compression starts.
- Release: Controls how quickly the sound returns to normal after the trigger.
4. Fine-Tune by Listening
- Play your track and adjust settings until you hear the desired pumping or ducking effect.
5. Experiment with Creative Sidechaining
- Try sidechaining vocals, hi-hats, or even entire drum buses for dynamic effects.
Tips for Effective Sidechaining
- Don’t overdo it — too much ducking can make your track sound unnatural.
- Use sidechaining to create space, not just for effect.
- Combine sidechain compression with EQ to carve out frequency space.
- Try using a dedicated sidechain plugin for more precise control.
