Koko Meter

Loudness, Dynamic range, Peak, Spectral balance and panorama at a glance!

Koko Meter Bridge is a compact JSFX metering plugin for REAPER, designed to embed directly in the TCP (track control panel) for always-on monitoring during mixing and mastering.

It displays three key loudness metrics — Integrated LUFS (ITU-R BS.1770-4 compliant with two-stage gating), Loudness Range (LRA), and True Peak — alongside a unique spectral cross display that shows stereo balance and frequency distribution at a glance.

A horizontal curve reveals spectral tilt deviations across 7 frequency bands (60 Hz – 14.6 kHz), while a vertical curve shows left/right balance per band — making mix imbalances immediately visible without opening a full analyzer. Click to reset all readings.
