Audio signal processing, sometimes referred to as audio processing, is the intentional alteration of auditory signals, or sound, often through an audio effect or effects unit.

Audio processing was necessary for early radio broadcasting, as there were many problems with studio to transmitter links.

Audio broadcasting ( be it for television or audio broadcasting ) is perhaps the biggest market segment ( and user area ) for audio processing products — globally.
