A brickwall limiter is designed to stop peaks at a defined output ceiling.
A brickwall limiter is a dynamics processor that prevents signal from exceeding a set ceiling. It uses very high ratios, fast timing, and often lookahead to control peaks.
It is commonly used at the end of a mastering or mix bus chain to manage peak safety and final loudness.
Pushing a limiter harder can raise average loudness, but it can also flatten transients, add distortion, smear groove, and trigger streaming normalization.
True peak behavior matters because samples that stay below the ceiling can still reconstruct above it during conversion.
Set the ceiling with delivery in mind, then increase input only until the limiter supports the mix instead of reshaping it. Compare at matched loudness.
Meter Core helps separate integrated loudness, sample peak, and true peak so the limiter is not judged by one number alone.
