LimiterΒΆ
Limiter is a brickwall limiter that prevents signals from exceeding 0 dBFS. By default a limiter is placed on the output FX chain to prevent clipping.

input sets the input gain.
release sets the time it takes for gain reduction to dissapear after peaks.
Tip
A low release results in quicker recovery of the original volume after peaks, while a higher release means peaks result in longer volume reduction. Low release settings tends to result more artifacts during limiting while a higher release can sound more transparent.
output sets the output gain of the limited signal.
algo switches between limiter algorithms: fast and clean.
Note
The fast limiter algorithm uses less CPU than clean and will be in most cases the best choice. When pushed very hard however, fast might occasionally not be able to catch transients and cause clipping. In these situations clean will perform better and limit more transparently at the cost of about 2.5x more CPU usage compared to fast.
