Clampit
Mastering Limiter
"A clean, loud, streaming-ready ceiling for your master bus — with three knee characters, LUFS metering, and program-dependent auto release."
Clampit is a lookahead true-peak limiter built to sit last on your master or bus. Set a ceiling your audio can't cross, dial in the release and knee character you want, and check your work with delta monitoring and built-in loudness metering. Signed and notarized for macOS as AU, VST3, and Standalone — it installs cleanly and gets out of your way.

FEATURES
Three Knee Characters
◆KNOCK (hard knee) — transparent and surgical for clean limiting
◆GLUE (6 dB soft knee) — smooth quadratic curve for musical limiting
◆CLOBBER (hard + tanh saturation) — aggressive character for heavy limiting with harmonic color
◆~20ms anti-pop crossfade on knee mode changes — no clicks during live transitions
Core Limiter
◆Input gain 0–24 dB, ceiling −6.0 to 0.0 dB, release 1–1000ms with skewed range
◆Lookahead 0–5ms with automatic DAW latency compensation
◆Stereo link 0–100% blend between independent L/R and fully linked stereo limiting
◆4x polyphase IIR oversampling for true peak inter-sample peak detection
LUFS Metering & Analysis
◆Full BS.1770 K-weighted LUFS-M (400ms), LUFS-S (3s), and LUFS-I (integrated, gated) metering
◆Crest factor readout (color-coded: green 6–8 dB, yellow 4–6 dB, red <4 dB)
◆GR waveform trace: 256-sample scrolling history with peak hold line
◆Clip counter, mono check, TPDF dithering (16-bit and 24-bit modes)
Workflow
◆Dual-stage program-dependent auto release adapts to crest factor and GR depth
◆Constant Loudness (LINK) — applies inverse of input gain for bias-free A/B comparison
◆Delta monitor — isolate exactly what the limiter removes, with 5 Hz DC blocker
◆Loudness-matched bypass, A/B comparison, and 15 factory presets
