LUMEN — Loudness Meter

LUMEN is a broadcast-grade loudness meter that fits in your pocket — and a second screen for your studio. LIVE: point your phone at the speakers and read LUFS (momentary, short-term, integrated), true peak, loudness range, PSR, PLR, correlation and a live spectrum, with targets for streaming, Apple, club and EBU R128. Mic-distance compensation keeps room readings honest. INSTRUMENTS: thirteen full-screen meters that count — spectrum analyser with peak hold and pink reference, loudness with target band and 30-second history, true peak with headroom, goniometer and correlation, dynamics (PSR) with zones, tonal balance by band, spectrogram, level history, crest factor, a VU with real ballistics, stereo width and balance, and a loudness histogram. Thirteen palettes. Freeze, reset, full screen. LUMEN PRO (one-time purchase) adds: LINK: run the LUMEN plugin in your DAW and the app becomes the session's big meter display over Wi-Fi — no cables, no setup, and nothing leaves your network. SCENES: fourteen line-drawn, audio-reactive worlds driven by the real analysis — terrain, radial, orbits, halo, aurora and more. Built for the iPad on the desk and the wall across the room. MY SCREEN: build your own meter wall of 1 to 6 tiles, any instrument or scene in each, each in its own colour. FILE: analyse any track from Files or iCloud for the definitive numbers.
