The compressor is one of the most ubiquitous tools used in music production. It is in the family of audio devices known as dynamics processors. So to understand the compressor, it’s helpful to first look at what we mean by dynamics in the context of audio.

Dynamics is the variation of amplitude (sound level) over time. A recording of a drum kit will be very dynamic, with loud snare and kick peaks, plus subtle ghost notes and room reverb making up the totality of the sound. Its dynamic range (the distance between the quietest part and the loudest part)is high. On the other hand, a synth pad — a long ambient texture with little variation in volume — is less dynamic. Its dynamic range is low.

Managing dynamics is important in the music production process, because we need to constantly balance the desire to have a punchy and impressive mix, with the reality that there’s only so much you can cram into your mix before you enter ‘too loud’ territory. So with this baseline understanding of dynamics, back to the compressor.

What does a compressor do?

As its name suggests, a compressor compresses audio. More specifically, it reduces its dynamic range by turning down the loudest parts of the audio and then raising the level of the overall signal — using makeup gain — to make the quiet parts more present in the mix.

The compressor in Suno Studio has all the common parameters for limiting dynamic range. A real-time meter shows the signal's position on the dynamics processing curve.

Compressor settings

The level at which the signal starts being compressed is set by a control called the threshold — a knob you will find on practically every compressor, hardware or software. The amount by which the gain is reduced is controlled by the ratio. For example, a ratio of 4:1 reduces a 4dB peak over the threshold to 1dB over. Other common compressor controls such as attack and release allow you to control how fast the compressor responds and how quickly it recovers after the signal drops below threshold.

But why on earth would you want to squash audio like this? Well, compressed audio is perceived as sounding louder, because the makeup gain is “turning up the quiet” even if the peaks remain the same. And a lot of the time, this is exactly why you would use a compressor; to make things sound louder or at least more consistent when there are other instruments in the mix.

One of the perennial jobs you will face as a music producer is to manage dynamic range as you are mixing your music. A compressor allows you to bring the loudest and quietest parts of your song into that same range, so everything captured is audible against other instruments and vocals. There is the risk of overcompression, where you squeeze the life out of your audio, though this can be used to creative effect. So the trick to using a compressor is to bring out the detail in your tracks so they sit well in the mix, while maintaining some of the dynamic range that gives them character and feeling. A great tip is to mix with your ears, not your eyes, so listen first and stop tweaking when it sounds good!

The Compressor plugin in Suno Studio

All this is relevant to us at Suno because Studio, our browser based DAW now has a suite of audio effects, compression included. You can use these effects to dial in your mix and make your project sound exactly the way you want it to.

The compressor in Studio is especially useful when you want to bring your own audio into Suno — either by uploading it or recording on to the timeline. With this raw audio, you’re definitely going to want to control dynamic range, to bring out the detail that might otherwise get lost.

Using the compressor in Suno Studio, you can employ other pro audio tricks like sidechaining, where you make the sound pump to the beat... more on this in another blog post.

Try it for yourself

If you already have songs on Suno, open up Studio to give compression a shot. If you’re new to music creation, Suno Studio is a great way to get started. It’s browser-based and all your files live in the cloud so you can access your music wherever you have a computer and a web connection. Studio is also simple to use, and comes free with every Suno Premier subscription.
