To encode and decode video files

To manipulate and improve the quality of audio and video signals

The role of a signal processor in an AV system is primarily focused on manipulating and improving the quality of both audio and video signals. Signal processors are designed to enhance signal fidelity, control various aspects such as equalization, compression, or effects, and ultimately ensure that the output is of the highest possible quality. This includes tasks such as noise reduction, dynamic range control, and other enhancements that contribute to a superior audio and visual experience.

In the context of audiovisual systems, a signal processor takes raw signals and refines them, making it essential for applications that require high-quality sound and image fidelity, such as in professional audio production, broadcasting, and live sound reinforcement. Therefore, the contribution of signal processors is crucial for optimizing the user experience in AV environments.
