Brickwall Limiter

What it is

A true-peak brickwall limiter following the ITU-R BS.1770-4 broadcast standard. 4× oversampling internally detects inter-sample peaks, the kind of overshoots that read as "under 0 dBFS" on a sample-peak meter but turn into clipping after streaming-platform encoding. Pick a ceiling, set a release, and the limiter keeps the output below that line — including after lossy encoding.

How to use it

• Pick a ceiling — -1 dBTP is the standard for streaming, -0.3 dBTP is acceptable on CD masters
• Set release — short releases (50-100 ms) for transparent loudness, longer (200-500 ms) for character
• Choose the limiter algorithm if multiple are exposed (transparent vs character)
• Pair with the export panel's LUFS Normalize for precise target loudness

What it affects

The last stage before output. The limiter catches every transient overshoot and prevents inter-sample clipping at the chosen ceiling. Because it works on 4× oversampled audio internally, it's safe for any streaming target. Pairs with LUFS Normalize: pick a LUFS target on export, the limiter ensures the file gets there without clipping the ceiling.
