A Compressor controls the dynamic range of a sound.  Compression prevents and restricts a sound from reaching volumes above a set threshold.

When the loudest part of a sound is reduced (compressed), it becomes closer in volume to the quietest part of the sound; this is how the dynamic range is reduced.

There will also be a reduction in output volume, but this can be restored by using the Make-up Gain. 

A compressor can also be set to react at certain times by using the Attack and Release controls. This means that only certain portions of the sound will be effected. Equally the strength of compression can be adjusted by using the Ratio Control.  These parameters can be used in combination to produce different effects like "pumping" and increasing the "punch" of a sound etc.
