Sailor LUFS

• The measurement was validated at 48 kHz with −153 dB of distortion on the test bench. Across the full 36-case matrix (3 sample rates × 4 tones × 3 levels), the worst case is −124 dB. An automatic guard fails the build if it ever gets worse than that.
• The clip guard holds under attack: pushing the manual helm +18 dB straight at the ceiling, output stays at −0.85 dBTP with the ceiling set to −1.0.
• Loudness detection uses ITU-R BS.1770-4 K-weighting. Sailor responds to measured loudness rather than relying only on raw peak or RMS level.
• Destination presets provide loudness and peak settings as starting points, not mandatory mastering levels. Choose the target for the actual delivery requirements.
• It moves ONE full-band gain — never an EQ — with asymmetric ballistics and a silence gate, so it never chases noise.
• A ±18 dB helm sits on top of the autopilot: your hand adds to the riding instead of fighting it, and it automates from the DAW.
• Gain Match A/Bs against bypass at equal loudness, so louder never tricks you into 'better'.
• Nothing on screen moves without a real measurement behind it: the captain only appears when the autopilot is on, and the sea gets rough because the signal really is unstable.
