Sailor LUFS

Your level, locked. Hands off the fader.

PRIVATE BETA VST3 · WINDOWS x64
Sailor LUFS — the real plugin interface
The interface is a character

Its interface is a helm: your audio is the sea, the boat rocks while the signal is unstable and settles when the level locks on target. A golden buoy marks the recommended spot — and reaching it is rewarded. Everything on screen is fed by the real engine, not decoration.

Nothing on screen is decoration: every meter and every reaction is fed by the real engine.

What it actually does

Measures loudness the broadcast way: momentary, short-term and integrated LUFS (ITU-R BS.1770-4 K-weighting) plus true peak with 4× oversampling.

Moves ONE full-band gain — never an EQ — to converge on your target LUFS, with asymmetric speed and a silence gate so it never chases noise.

Predictive clip-guard: gain never rises past the point that would eat your headroom — it backs off before the peak happens, not after.

Collision Guard with lookahead guarantees a real dBTP ceiling (4× oversampled detection), with soft-knee so sustained tones stay clean.

"Leveling" strength rides harder only on sources that jump around (vocals, live instruments) and stays transparent on stable material.

12 real streaming/broadcast presets, each with its own LUFS target, true-peak ceiling and boost policy.

Ride Fader ±18 dB: your hand on top of the autopilot — it adds to the riding and can be automated from the DAW.

Gain Match: A/B against bypass at equal loudness, so louder never tricks you into 'better'.

Honest ceiling advisor: it tells you when the true-peak ceiling makes your target unreachable — telemetry only, it never touches the audio.

Every claim above is backed by the shipping code — how we measure is documented in the methodology. Methodology →

Included Se7en Audio Server — the engine that runs the DSP outside your DAW when it's on; zero setup, automatic fallback to local.

Part of the line

The heavy engine, outside your DAW.

Every Se7en plugin can hand its heavy DSP to the Se7en Audio Server — a separate process, outside your DAW's audio thread — and the plugins can feed each other through internal sidechain groups, no DAW buses. No server? It always sounds: local processing is instant fallback.

How the engine works

Private beta

Get it first

Sailor LUFS is in private beta. The list hears about the release — and the launch price — before anyone else. No spam.

Straight answers

Does it replace a limiter on my master?
No. It levels program material toward a loudness target with a true-peak safety ceiling. Your creative limiter/mastering chain is still yours — Sailor LUFS keeps the level honest before and between those stages.
Will it pump like a compressor?
It moves one wideband gain with slow asymmetric ballistics and a silence gate — designed for transparency, not pumping. It is a leveler, not a dynamics effect.
Do I need the Se7en Audio Server?
No. The plugin always works: it processes locally by default and can delegate the heavy DSP to the server when it's running. If the server disappears, it falls back instantly.

Who builds this

These tools come out of a working studio — built by a producer with 25 years at the craft, for his own sessions first. If you make music and already have an audience, the studio also takes collaborations.
