Compressors are audio processing tools used to control the dynamic range of a sound signal. Their main function is to reduce the difference between the loudest and softest parts of a track, making the audio more balanced and consistent. Compressors also help make music sound fuller, clearer, and more polished during mixing and mastering. They are widely used across all music genres, from live recordings to studio productions, and are suitable for producers, audio engineers, musicians, and students at any level. Compressors are typically used within Digital Audio Workstations (DAWs) to shape the volume, dynamics, and overall sound quality of individual tracks or full mixes.
