What is the primary function of a compressor in audio technology?

The primary function of a compressor in audio technology is to reduce the dynamic range of an audio signal. This process effectively controls the volume levels in a recording or live performance by automatically lowering the volume of the loudest parts and raising the volume of the quieter sections.

Dynamic range refers to the difference between the loudest and softest sounds within an audio signal. By compressing this range, the compressor allows for a more consistent sound level, ensuring that quieter sounds are more audible without making the loud sounds overwhelmingly intense. This is especially useful in various audio applications, such as music production, broadcasting, and live sound reinforcement, where maintaining an even audio level can greatly enhance the listening experience.

Using a compressor, audio engineers can achieve a more polished sound, making it a vital tool in professional audio production.
