Sidechain Compression: How to Get That Pumping Effect

Sidechain compression is a powerful mixing technique that creates the signature “pumping” effect heard in many EDM tracks. By dynamically lowering the volume of one sound based on the presence of another, this method allows kick drums to cut through the mix while keeping other elements controlled and energetic. Another common use of sidechain compression is to use one audio signal to control the level of another, a process known as “ducking.” This is often used in scenarios such as using a kick drum to control the level of a bass track or ducking a music track from a narration source when working on video. In this guide, we’ll explore how sidechain compression works, why it’s essential in EDM mixing, and how to achieve the perfect pumping effect.

What Is Sidechain Compression?

Sidechain compression is a process where the level of one track is automatically reduced when another track plays. The most common use case is in EDM and dance music, where the bass or synths duck in volume every time the kick drum hits, creating a rhythmic, breathing motion.

Why Use Sidechain Compression?

• Clarity in the Mix – It ensures that the kick drum remains dominant without clashing with bass-heavy elements.
• Rhythmic Groove – The pumping effect adds movement and makes the track feel more dynamic.
• Space Management – Helps create separation between competing frequencies, particularly in low-end-heavy mixes.

How to Set Up Sidechain Compression

Most modern digital audio workstations (DAWs) support sidechaining, but the exact method varies depending on the software you are using. Be sure to check your DAW’s manual or online resources to learn the specific steps required for your setup.

Many stock compressors in DAWs like Ableton Live, FL Studio, Logic Pro, and Cubase support sidechaining. Additionally, third-party plugins such as Wave Arts TrackPlug 7, FabFilter Pro-C 2, and Xfer OTT offer advanced sidechain compression features for more precise control over your mix.

1. Load a Compressor on the Target Track – Insert a compressor on the track you want to duck, such as a bass or pad.
2. Enable Sidechain Input – Most modern compressors have a sidechain option. Activate it and choose the kick drum as the sidechain source. Be sure to read the documentation for your favorite compressor plugin and DAW to learn how to properly route the source signal to the sidechain input of the plugin.
3. Adjust Threshold and Ratio – Lower the threshold until the compression is noticeable. A ratio of 4:1 or higher is common for pronounced pumping.
4. Tweak Attack and Release – A fast attack ensures immediate ducking, while a short-to-medium release (50-200ms) controls how quickly the sound recovers.

Additional Tips for a Clean Pumping Effect

• Use Volume Shaping – If sidechain compression alone doesn’t provide the desired effect, consider using volume automation or plugins like Xfer LFO Tool or Cableguys ShaperBox for precision control.
• Multiband Sidechain Compression – Instead of ducking the entire frequency range, apply sidechain compression only to the low end to keep high frequencies intact.
• Experiment with Groove – Instead of sidechaining strictly to every kick, try different rhythmic patterns to add unique movement to your mix.

Conclusion

Sidechain compression is an essential technique for achieving a professional and polished EDM mix. By using it effectively, you can enhance clarity, create engaging movement, and ensure that your kick drum remains the driving force of your track. Whether you’re producing house, trance, or future bass, mastering this technique will take your music to the next level.
