Hit your streaming loudness target with confidence.
Gaugex Raw is a dead-simple LUFS meter: pick your streaming target, then watch a big integrated-LUFS readout with a green/amber/red on-target light. It measures only — your audio passes through completely unchanged, bit-transparent with zero added latency.
Fully signed and notarized for macOS as AU, VST3, and Standalone.

Gaugex Raw is a loudness meter built on the ITU-R BS.1770-4 / EBU R128 standard.
- Integrated LUFS — the big, central readout: your overall program loudness, measured with proper BS.1770-4 gating (−70 LUFS absolute gate, −10 LU relative gate).
- Momentary LUFS — 400 ms sliding-window loudness.
- Short-Term LUFS — 3-second sliding-window loudness.
- True Peak (dBTP) — inter-sample peak, measured with 4× oversampling to catch peaks that a normal sample meter misses.
Pick where your track is headed and the on-target light tells you if you're there:
- Spotify — −14 LUFS
- YouTube — −14 LUFS
- Apple Music — −16 LUFS
- Club — −6 LUFS
- Custom — dial in any target from −24 to −6 LUFS
The on-target light reads green when you're within 1 LU of target, amber within 3 LU, and red beyond that, with a live delta showing exactly how far off you are. The Fire Head rides the loudness as a living needle — a dim ember under target, a calm glow on target, a white-hot flicker when you're too loud.
Gaugex Raw does not process, shape, or colour your sound. The signal passes through bit-transparent, and it reports zero latency to the host — so you can leave it inserted anywhere in your chain without affecting playback or timing. A Reset button clears the integrated measurement so you can start a fresh reading.
No factory presets — the streaming target selector is all you need.
