Real-Time RMS & True Peak Monitoring

Overview

RMScope is a lightweight RMS and true peak meter that provides real-time visual feedback of RMS levels and true peak values. The plugin features a VU-style horizontal meter with gradient fill, numeric overlays for RMS and True Peak, input/output side meters/clip indicators, and low CPU usage for precise monitoring. RMScope uses VU-style smoothing to approximate human-perceived loudness while also displaying true peak values.

Key Features

RMS & True Peak Metering

Displays smoothed RMS values using per-sample VU smoothing.
Shows True Peak numeric overlay with peak hold (0.5s) and fade-out.
Central horizontal VU meter with gradient fill (green yellow red) and side input/output meters for fast monitoring.

Peak Hold & Fade

Peak hold line tracks the highest output peak in real-time, decaying smoothly after 0.5s hold.
Numeric RMS & TP overlay fades along with the peak hold line for clarity.

Controls

RMS Window – Select 300ms (VU) or 600ms (40A) smoothing. Hoverable tooltip guides usage.
Clip Indicators – Displays input/output clipping; click to reset.
