True-peak limiter · loudness finisher

Loud where it counts.
Transparent everywhere else.

PEAK finishes your master at the ceiling, keeps the transients breathing, and proves the peaks survive the codec before you ship.

5-day trial, no account. Audio passes through bit-exact until you activate.

The PEAK plugin interface: machined graphite panels, onyx knurled knobs, gold readouts, twin true-peak meters and the codec reference panel.

The idea, live

A ceiling nothing gets past. Not even the codec.

Most limiters guard the sample peak. Your DAC, and every lossy codec, reconstruct a signal that rides higher between the samples, so a bounce that looked safe clips on Spotify. Drag the ceiling. Switch a codec on. Watch the difference.

No codec. The gold trace is PEAK holding the output under the ceiling. The dim trace is your raw input.

What's under the hood

One finisher. Every decision it makes, shown to you.

Drive · Ceiling

Loud, honestly

Drive gain into the limiter, set the true-peak ceiling once. PEAK measures the way DACs actually reconstruct, 4× oversampled, so peaks survive your DAW, the codec and the listener's speakers.

Codec Shield · SURVIVE

Proof it ships clean

Pick a target, Apple, Spotify, YouTube, Tidal, Club, and PEAK encodes ahead of you. SURVIVE hands you a receipt: the exact true-peak your listeners get after AAC, Opus or MP3.

If You Insist

LOUD · COLOUR · EXTRA

Need more than clean? A soft/cubic/hard clip stage, an odd-harmonic COLOUR for air, and EXTRA, a single knob that cascades the loudness levers so you push once, not five times.

Match Ref · Drive Cmp

Land on a reference

Drop a reference master and PEAK solves its own knobs on-device so your output measures like it. No reference? DRIVE CMP maps every Drive setting's trade-off in one table.

Transparency

Know what you spent

A live transparency score with the cause named, the band, the moment, the punch you traded for loudness. When you're overcooking it, PEAK says so before the client does.

Delta · Dither

Trust, then verify

Delta-listen every change PEAK makes, silence means perfect transparency. Proper truncation dither for 16 and 24-bit delivery, and A/B/C/D snapshots to compare moves.

Post-limiter forensics

The analysis panel that keeps you honest.

  • Transparency score, session-tracked, with the dominant cause called out by band and frequency.
  • Punch loss per band, so you see exactly where crest reduction ate the groove.
  • Codec ISP headroom and ΔPSR retained, the two numbers that decide whether it survives delivery.
  • Cause replay, jump straight to the worst moment and hear it, then a one-click deliver target with APPLY.
Get PEAK
PEAK's analysis panel: tonal and width shift, a transparency score of 92, per-metric grades, punch loss by band, a 60-second history graph of LUFS, gain reduction and transparency, cause replay and delivery targets.
