When it comes to audio processing, there are numerous techniques that can help enhance and transform your sound. One such technique that’s become increasingly popular is sidechaining. But what does sidechaining mean, and how can it be used to elevate your music productions? In this article, we’ll delve into the world of sidechaining, exploring its concept, applications, and benefits, as well as provide practical tips for implementing it in your own productions.
What is Sidechaining?
At its core, sidechaining is a dynamic audio processing technique that allows you to control the volume of one audio signal (the “slave” signal) based on the level of another audio signal (the “master” signal). This process is often used in music production, particularly in genres like electronic dance music (EDM), hip-hop, and pop, where it’s essential to create dynamic, engaging, and attention-grabbing soundscapes.
In a sidechaining setup, the master signal is typically the main element of your track, such as the kick drum or bassline. The slave signal, on the other hand, is typically an auxiliary track that contains an effect, like a compressor or reverb, which is used to enhance or modify the master signal. By linking the two signals together, you can create a dynamic relationship between them, where the level of the slave signal responds to the level of the master signal.
How Does Sidechaining Work?
To illustrate how sidechaining works, let’s consider a common scenario: you’re producing an EDM track, and you want to create a massive, pumping bass sound. You’ve set up a compressor on your bass track, but you want the compressor to respond to the kick drum’s level, so that when the kick drum hits, the bass compressor pumps and reduces the volume of the bass.
Here’s how you would set up the sidechaining process:
- The kick drum track is the master signal, feeding into the compressor’s sidechain input.
- The bass track is the slave signal, feeding into the compressor’s main input.
- The compressor is set to respond to the level of the kick drum, reducing the volume of the bass when the kick drum reaches a certain threshold.
As the kick drum hits, the compressor reduces the volume of the bass, creating a Dynamic, pulsing effect that adds energy and movement to your track. This is just one example of how sidechaining can be used to create exciting and engaging soundscapes.
Key Benefits of Sidechaining
Sidechaining offers several key benefits that make it an essential technique in music production:
Creates dynamic interest: By linking two audio signals together, sidechaining can create dynamic, interactive relationships between different elements of your track, adding movement and energy to your sound.
Enhances rhythm and groove: Sidechaining can be used to create a sense of rhythmic tension and release, adding a sense of groove and momentum to your track.
Opens up creative possibilities: With sidechaining, you can experiment with a wide range of creative possibilities, from subtle nuances to dramatic, over-the-top effects.
Common Applications of Sidechaining
Sidechaining is an incredibly versatile technique that can be applied in a wide range of musical contexts. Here are some common applications of sidechaining:
Rhythmic Ducking
One of the most common applications of sidechaining is rhythmic ducking, where the level of a secondary element (like a synth pad or percussion track) is reduced in response to the level of a primary element (like a kick drum or snare). This creates a sense of rhythmic tension and release, adding energy and movement to your track.
Pumping Bass
As we mentioned earlier, sidechaining is often used to create pumping bass sounds in EDM and dance music. By linking the bass compressor to the kick drum’s level, you can create a dynamic, interactive relationship between the two elements, adding weight and energy to your low end.
Automating FX
Sidechaining can also be used to automate the level of effects like reverb, delay, or distortion. By linking the effect to the level of a specific track or instrument, you can create dynamic, interactive relationships that add depth and interest to your sound.
Tips and Tricks for Implementing Sidechaining in Your Productions
Now that we’ve explored the concept and applications of sidechaining, let’s dive into some practical tips and tricks for implementing it in your own productions:
Choose the Right Compressor
When it comes to sidechaining, the compressor you choose can make a big difference. Look for a compressor with a sidechain input and a strong, responsive attack and release. Some popular compressors for sidechaining include the FabFilter Pro-C2, the LA-2A, and the 1176.
Experiment with Threshold and Ratio
The threshold and ratio settings on your compressor will determine how aggressively the compressor responds to the master signal. Experiment with different threshold and ratio settings to find the right balance for your track.
Use Makeup Gain to Compensate
When sidechaining, it’s common for the compressor to reduce the overall level of the slave signal. To compensate, use makeup gain to bring the level back up to where you want it. This will ensure that your track stays loud and vibrant.
Sidechain Multiple Tracks
Why stop at just one sidechain? Experiment with sidechaining multiple tracks to create complex, interactive relationships between different elements of your track.
Automate the Sidechain
Take your sidechaining to the next level by automating the sidechain input. This can create a sense of dynamic interest and movement, adding depth and complexity to your track.

What is sidechaining and how does it work?
Sidechaining is an audio processing technique used to dynamically control the level of one audio signal based on the level of another audio signal. It’s commonly used in music production, post-production, and live sound to create interesting effects, enhance mixes, and even create entire genres of music. The process involves using a compressor plugin or hardware unit, which has a built-in sidechain input that receives the audio signal from another track or source.
In a sidechaining setup, the compressor reduces the volume of the main audio signal (the “target” track) when the level of the sidechain input signal exceeds a certain threshold. This allows the target track to “duck” or make way for the sidechain signal, creating a dynamic and interactive effect. For example, in a dance track, the kick drum might be used as the sidechain signal to duck the level of the bass guitar, creating a pumping effect that emphasizes the kick.
What are the key components of a sidechaining setup?
The key components of a sidechaining setup include a compressor plugin or hardware unit, a target track, and a sidechain source track. The compressor is the device that performs the dynamic volume reduction, and it’s typically set up to respond to the level of the sidechain signal. The target track is the audio signal that’s being processed and volume-reduced, while the sidechain source track provides the signal that triggers the compression.
The compressor’s threshold, ratio, attack, and release settings all play important roles in shaping the sidechaining effect. The threshold determines how loud the sidechain signal needs to be to trigger compression, the ratio determines how much compression is applied, the attack determines how quickly the compression kicks in, and the release determines how quickly the compression returns to its normal state.
What are some common applications of sidechaining?
Sidechaining has a wide range of applications in music production, post-production, and live sound. One of the most common uses is to create a “pumping” or “breathing” effect, where the level of one track is dynamically reduced to make way for another track. This is often used in electronic dance music to create a sense of energy and tension. Sidechaining is also used to create vocal ducking, where the level of a vocal track is reduced when a backing vocal or instrumental element is playing.
Another common application of sidechaining is in film and television post-production, where it’s used to create dynamic and immersive sound design elements, such as gunfire or explosion sounds that duck the level of the dialog or music tracks. Sidechaining can also be used in live sound to create a more dynamic and engaging mix, such as by using the level of the lead vocal to duck the level of the backing vocals or instruments.
Can I use sidechaining with any type of audio signal?
While sidechaining can be used with any type of audio signal, the effectiveness of the technique depends on the type of signal being used and the desired outcome. In general, sidechaining works best with signals that have a clear and defined attack, such as drums, percussion, or vocal phrases. This is because the compressor is able to quickly respond to the transient peaks in the sidechain signal and apply compression accordingly.
In contrast, sidechaining may not be as effective with signals that have a more even or sustained level, such as ambient pads or atmospheric textures. In these cases, the compressor may not be able to respond quickly enough to the changes in the sidechain signal, resulting in a less dynamic and interactive effect. However, with careful setting of the compressor’s attack and release times, sidechaining can still be used with these types of signals to create interesting and creative effects.
What are some common mistakes to avoid when using sidechaining?
One of the most common mistakes to avoid when using sidechaining is over-compression, which can result in an unnatural and fatiguing sound. This can happen when the compressor is set too aggressively, causing the target track to be reduced to an unnatural level. To avoid this, it’s essential to set the compressor’s threshold, ratio, and gain makeup levels carefully, and to listen critically to the processed signal.
Another common mistake is not setting the attack and release times of the compressor correctly, which can result in an uneven or “pumpy” sound. It’s also important to ensure that the sidechain source track is properly gain-staged and EQ’d to ensure that the compressor is responding to the correct frequency range and level.
Can I use sidechaining with other types of processing besides compression?
While compression is the most common type of processing used in sidechaining, it’s not the only option. In fact, sidechaining can be used with a wide range of processing types, including reverb, delay, distortion, and EQ. For example, sidechaining can be used to create a dynamic reverb effect, where the level of the reverb tail is reduced when the level of the dry signal increases.
In this way, sidechaining can be used to create a more subtle and nuanced sound, where the processing is tailored to the specific needs of the mix. By using sidechaining with different types of processing, producers and engineers can create more complex and interesting effects that enhance the overall sound and texture of the music.
