Loudness, Dynamics and Peak Metering

The Super Meter combines three measurements in one module: loudness (LUFS), dynamics (TrueDyn) and peaks (True Peak). The outer rim shows short-term readings over a 3-second span, while the inner rim shows integrated readings from the start of the recording.

A LUFS Histogram tracks loudness and short-term dynamics over time, so you can compare sections of a song and spot where the True Peak limit is exceeded. Target Validators light up when your loudness target is reached or when True Peak Max is passed.

Phase, Spectrum and Mobile Displays

The Phase Scope shows the correlation between left and right channels, helping you identify mono signals and channels that are out of phase. The Spectrum Analyzer offers real-time frequency analysis, including a mid-side stereo view, and lets you zoom into the low end.

Each module can be added, resized and moved, and the skins, colours, targets and layout are customizable. Through the companion app, you can link multiple mobile devices to the desktop plugin, so several synced meter displays run at once.
