Limiter & True Peak

The last device on every master.

Brick-wall ceiling. The last device on every master.

// WHAT IT DOES

A Limiter is a hard ceiling: nothing crosses it. You set a Ceiling (the max output level) and a Gain (how much to push the input up), and the Limiter clamps anything that would exceed the ceiling.

On a master, the Limiter's job is loudness control without clipping. Keep ceiling around -1 dBTP for streaming services — that leaves headroom for codec encoding artifacts.

Think of it like → Like a height limiter at a parking garage — anything taller than the bar gets squashed flat.
▸ WHY YOU CARE
  • Final loudness for streaming/release.
  • Catches peaks that would clip your converter.

WHAT CHANGED
  • Defaults — toggle A/B or load a preset to hear the device.
WHAT TO LISTEN FOR
  • Push input gain — track gets louder until distortion appears.
  • Compare commercial mix loudness with and without limiter.
  • Too much = lifeless, pumping wall of sound.
HOW TO USE
Press PLAY → tap a PRESET → toggle A/B to compare dry vs processed. Twist knobs to hear how each parameter changes the sound.

▸ HOW IT WORKS

Input → look-ahead delay → peak detector → gain reduction → ceiling clamp → output.

▸ LISTEN FOR
  • Transparent peak control at low GR.
  • Pumping/breathing as GR increases.
▸ WALKTHROUGH (3 steps)
  1. 1. DO: Drop Limiter on master. Ceiling -1 dB, Gain 0 dB, Lookahead 3 ms.
    ▸ LISTEN: Master sounds the same; ceiling protected.
  2. 2. DO: Push Gain +3 dB.
    ▸ LISTEN: Mix loudens; tiny GR on transient peaks.
  3. 3. DO: Push Gain +6 dB.
    ▸ LISTEN: Pumping on kick/bass — too much.
▸ COMMON MISTAKES
  • Using Limiter to fix mix problems instead of polish.
  • Ignoring True Peak then blaming the codec.
