Audio processing or audio signal processing is the intentional alteration of sound using an audio effect or effects unit. In broadcasting applications, the most important audio processing takes place just before the transmitter. When working on an on-air broadcast, timely and complete audio signal processing is critical to the overall success of the live streaming audio content. Ideally, an audio processor used for broadcast should: prevent or minimize overmodulation, compensate for non-linear transmitters, adjust overall loudness, and correct errors in audio levels.
