The ceiling is the maximum output level in dBFS: ceilingDb defaults to -0.2 dB and the limiter clamps the signal to it on export.

What this tool actually does
Control peaks with the ceiling and limiter behavior actually implemented, without claiming true-peak protection unless verified.
The threshold, thresholdDb (default -2.0 dB), sets where limiting begins, so peaks below it pass untouched and only what crosses it is held down.
Lookahead, lookaheadSec (default 3 ms, taken from limiterParams.lookaheadMs / 1000), opens a short delay so a peak is caught before it reaches the ceiling instead of being clipped.
Release, releaseSec (default 50 ms, taken from limiterParams.releaseMs / 1000), sets how quickly gain returns to unity after a peak is controlled.
The limited render is written as WAV, MP3 or AIFF and downloaded in the browser from the plugin export button, while bypass returns the untouched buffer.
Real-world use cases
What people actually solve with this converter before they play live.
Prepare tracks before a DJ set.
Fix or process files without opening a full DAW.
Keep the workflow focused on the specific task instead of a general-purpose editor.
