You can use a compressor to bring out some of the quieter elements of the synth, or make it more even-sounding.You can compress a synth sound with a slow attack compressor, to give a sharper attack or “pluck” sound on a synthesizer.The “sucking” sound you hear with each kick drum is the result of sidechain compression. This sound might be viewed as a bit dated by some, but sidechaining can be used more subtly. The prime example of a sidechained sound would be “Call On Me” by Eric Prydz. This means using an audio input to control the compressor, so that the sound “ducks” as another sound comes in. Some of the uses of compression for synths include: A compressor on a synth won’t drastically alter the sound but it will make some changes to the audio properties. This is what a lot of people love about music production – the chance to experiment. Below that is an image of a soundwave that has been compressed and you can see the difference between quietest and loudest notes is much less. In the screenshots below of two sound waves you will see the first uncompressed signal which has a large dynamic range (difference between quietest and loudest notes). It “compresses” the audio range so that the sound is far more consistent. It puts all of the audio on a more even keel, either by attenuating the audio when it creeps over a certain volume, or by boosting the volume when it dips too low.
But it turns out what a compressor does is really quite straight forward.Ī compressor will impact the ‘dynamic range’ of audio, this means how loud and quiet the different sections get. I remember before I learned what a compressor did I was very daunted, it sounded complicated and a tool saved for use only by experienced producers.
You don’t even have to fully understand how it works, just how it is likely to make affect your audio. To understand why it might be used on a recording of a synthesizer, it is important to understand what a compressor does to the sound. Compressors can either be post-production tools in your digital audio workstation, or they can be physical pieces of hardware in a studio or in a guitar rig.
