Gaugex Raw

Gaugex Raw is a free loudness meter for macOS. Instead of a knob it centers on a single target selector — Spotify −14, YouTube −14, Apple Music −16, Club −6, or Custom — with a big integrated-LUFS readout and a green/amber/red on-target light, plus momentary, short-term, and true-peak readouts. It measures only: your audio passes through bit-transparent with zero latency.

Simple and lightweight by design, it's built for fast workflows — leave it on any channel to hone in on your loudness at a glance and keep the session moving, with no menu-diving and nothing to set up.

Formats: AU, VST3, and Standalone — Universal Binary (Apple Silicon + Intel), code-signed and notarized by Apple, so it installs cleanly on macOS. Free to download.
