NUGEN Audio VisLM 3 is the go-to loudness meter for audio post-production, broadcast, podcasts, and game audio. It allows you to stay up to date with ever-evolving loudness standards, thanks to next-generation measurement that includes multi-stem monitoring, QC report export, and support for up to 9.1.6 surround sound.

Loudness meter with 24-hour history and automatic Integrated measurement

VisLM is your go-to tool when working under tight deadlines. The plug-in stores up to 24 hours of loudness data, synchronized with the timecode provided by the DAW, and the navigable history view shows how these values change over time. As soon as a change to the mix is played back through VisLM, the Integrated measurements update automatically, without the need to remeasure the program from start to finish. VisLM can also measure faster than real time via AudioSuite.

True Peak and Inter-Sample Peak Monitoring

In addition to loudness, VisLM measures and displays True Peak values, accurately anticipating and flagging inter-sample peaks. This helps you avoid potential distortion, speed up the quality control process, and save on costly post-production corrections.

Multi-stem Monitoring, Notes, and QC Reports

The Stems tab displays data from multiple instances of the plug-in—such as the full mix, dialogue, music, and effects—in a single window, providing an overview of the entire project rather than just the master bus. The Notes tab lets you add timestamped comments and feedback directly on the history graph, making them easy to share with colleagues and collaborators. Rounding out the features are LDR (loudness-to-dialogue ratio) measurement, support for up to 9.1.6, and QC Report export.
