Cota
Loudness metering, but beautiful.
ITU-R BS.1770-4 · stereo to 9.1.6 · plugin + standalone

Beautiful metering.
And f***ing accurate.
EBU R128 allows ±0.1 LU of measurement error. Cota lands within 0.04 LU — every metric sitting well inside the published ITU-R BS.1770-4 tolerance, on every release.
Bars show worst-case error as a fraction of the EBU tolerance (dashed = limit). Less is better — every measure lands far inside spec.
When Cota reads −14 LUFS, you're at −14 LUFS — on Spotify, Apple, YouTube or broadcast. Measured against the published EBU R128 tolerances, every metric, every release.
Gauge
Integrated, short-term and momentary LUFS, loudness range and true peak — with an over-target warning.
Spectral terrain
A real-time spectral analyser in four luminous styles — Aurora, Topo, Bars and Neon.
Spatial
See your mix in space — 3D spatial metering from stereo all the way to 9.1.6.
Dashboard
Gauge, history, spectrogram, goniometer and per-channel true-peak together on one screen.
Remote view
Live meters served over your network — open Cota on a phone, tablet or any browser.
Plugin + standalone
Runs as a CLAP, AU and VST3 plugin in your DAW, or as a standalone app on files and live input.
Read your loudness at a glance
A 300° contour gauge with integrated, short-term and momentary LUFS, loudness range and true peak — and a glowing over-target warning the moment you cross the line.
Your whole mix, on one screen
Gauge, loudness history, spectrogram, goniometer and per-channel true-peak together — everything you need to sign off a master without switching views.
- Per-channel true-peak metering

Any screen is a monitoring station
Cota serves its meters over your network, so you can watch loudness from a phone, tablet or any browser in the room — the identical bytes the app renders.
