Limiter

Limiter are the same as compressor except that signals exceeding the threshold level are reduced at ratios of 10:1 or greater. Limiter can be set to prevent all signal from going above the given amplitude. Prevent the audio signal from being too intense, causing distortion or damage to the loudspeakers.

An example showing the use of a limiter:
The sound of a dropped microphone may be too intense, and cause damage to the audio system's loudspeaker.
