Compression and decompression

A compressor is sometimes used to reduce the dynamic range of a signal for transmission, to be expanded afterwards. This reduces the effects of a channel with limited dynamic range.

Compression as an effect

Gain Pumping, where a regular amplitude peak (such as a kick drum) causes the rest of the mix to change in volume due to the compressor, is generally avoided in music production. However, many dance musicians use this phenomenon in a creative way, causing the mix to 'pump' rhythmically in time with the beat.
