ABSTRACT
A true limiter has one critical task: to ensure that signals do not overshoot the threshold. May I add, no matter what. Often it is sudden transients and peaks that we limit. Limiters have many applications outside mixing: they are necessary to protect PA systems, to prevent one FM radio station from intruding on the frequency band of an adjacent station and in mastering, limiters help maximize loudness. In mixing, the task of limiting peaks is essential when the final mix is printed, where signals must not exceed 0 dB before being converted to digital or bounced to integer-based files (or any other digital media).
