Audio processors are devices or software that manipulate audio signals to enhance sound quality or achieve specific effects. They can adjust volume, equalization, and dynamics, making audio clearer and more balanced. Common types include equalizers, compressors, and reverb units, each serving different purposes in audio production. These processors are widely used in various fields, including music production, broadcasting, and live sound reinforcement. They can be found in digital audio workstations (DAWs), mixing consoles, and even in consumer devices like smartphones and home theater systems. Their role is crucial in delivering high-quality audio experiences.
