Less Limiter

A brickwall whose ceiling is a mathematical property, held in true peak.

macOS: AU and VST3, Apple silicon · Windows: VST3, 64 bit

Overview

Less Limiter's gain computer is built so the ceiling is a mathematical property of the chain, not a target it usually hits: release, sliding maximum, then smoothing, in that order. Say -1 dBTP and it is still -1 dBTP after the encoder.

Installation

Run the installer for your platform. On macOS the AU and VST3 versions install for all users; on Windows the VST3 installs under Common Files. Factory presets install into your user preset folder and are never overwritten: presets you save land in the same folder and stay yours.

Controls

GAINGain: drive into the limiter. More gain = louder and more limiting
CEILINGCeiling: the output never passes this level (-1 dBTP is a safe release value)
RELEASERelease: how fast gain comes back after limiting. Too fast distorts lows
LOOKAHEADLookahead: catches transients cleanly ahead of time. Adds that much latency
TRUE PEAKTRUE PEAK: limit inter-sample (oversampled) peaks, not just sample peaks
TP RESETReset the output true-peak hold readout

Workflows

Set a streaming-safe ceiling

Set Ceiling to -1 dBTP with True Peak on. Raise Gain until the loudness sits where you want it; the ceiling holds, including after encoding.

Catch peaks transparently

Use the Transparent Catch preset. With the ceiling just below the peaks, only the loudest moments are touched; everything else passes unchanged, and a test asserts that on every build.

Push loudness deliberately

Raise Gain past the ceiling and listen as density grows. The release control trades punch against loudness; the meter shows exactly how much reduction you are buying.

Tips

The ceiling is a guarantee: output true peak never exceeds it in test.
True Peak mode measures inter-sample peaks per BS.1770, so the level survives encoders.
Below the ceiling the limiter is a straight wire.
