This article is for you, if you're unfamiliar with the princliples of using compression, or would like a reminder of how to approach this aspect of music recording. We'll touch on various settings - threshold, compression ratio, attack and release times, and of course, the knee, as well as where to place the unit in your signal paths.

Compressors are a type of signal processor used by recording engineers. They can be thought of as a kind of "automatic fader". They are used either to fix problems, for example, too great a dynamic range in the recording; or to enable creative mixing for example, by adding presence to the sound track.
