A compressor effect is one of the most commonly used and effective effects in music production. It is the ability to change the sound of a track by the use of one or more compressors (all the famous compressors from different manufacturers have compressors). A compressor can make a track louder, softer, clearer, wetter, cleaner, darker, crunchier, etc. The ability to take advantage of all these characteristics can help you achieve a completely different musical sound.
The typical compressors use linear controls which are available on both rotary and ring modulators (SRR). On ring modulators, the input level changes as the amount of modulator is turned on and off. On the other hand, on rotary controllers the control knob is changed in either direction. On some types of compressors, the level is reduced or increased to either increase or decrease the perceived volume level. Some compressors have multiple frequencies, while others do not.
There are many presets that allow you to quickly experiment with different types of compressors and start to understand how to use a compressor effect to your advantage. By experimenting with different types of compressors you will soon be able to understand how a compressor can be used for a variety of uses. A compressor effect can help you achieve one or more desired objectives by using different aspects of the audio spectrum. For example, if you wish to increase the volume of a track and you have used a compressor with a high output level, you may then want to attempt to lower the level of the other frequencies, to balance out the volume of the high output. Another possibility would be to use a compressor to brighten a track, since it is known that low level sounds tend to be enhanced by high level sounds. Using a compressor with a high threshold and low pass is known to be beneficial when trying to set up your audio processing into a mono audio channel.
