Limiters are devices or software used in audio processing to control the maximum level of a sound signal. They prevent distortion by ensuring that the audio does not exceed a specified threshold, which is particularly important in music production and broadcasting. By automatically reducing the volume of loud sounds, limiters help maintain a consistent audio level. In addition to music, limiters are also used in various fields such as telecommunications and broadcasting to protect equipment from overload. They can be found in mixing consoles, recording software, and live sound systems, ensuring that audio remains clear and undistorted during playback or transmission.
