An audio & video processor is an integrated chip that has been designed to enhance and clean up audio and video signals before they are transmitted.
Audio processing is available in both digital and analogue. Analog converts a sound wave into an electrical signal. The signal looks like a sound wave and is processed with the least distortion. Digital audio processing converts an analogue audio signal into digital form. This is normally a binary code that can be interpreted by a computer. Digital alters the sound from a continuous wave to other information meaning the ear hears no difference in the sound.
Video processing uses signal processing to optimise video signals for a clear video stream. It has a variety of functions, including:
Audio processors are widely used in applications such as:
Video processors have a variety of use in applications such as:
