NUGEN Audio VisLM 2 Loudness Measurement

• True Peak level meters
• Timecode locked ReMEM
• Automated loudness overdub
• Leq(m) and Leq(a) measurement
• Momentary, Short-term & Integrated loudness
• ITU-R BS. 1770 | EBU R128 | CALM compliant
• Suitable for Netflix best practice
• Navigable flags & alerts

VisLM remembers up to 24 hours of loudness data, locked to a timecode received directly from your NLE/DAW. Any minor edit or overdub triggers overall loudness updates, eliminating the need for end to end re-measurement. Plus loudness data is saved with the session.

Offline AudioSuite scans can be transferred to the real-time meter for faster than real-time measurement. ReMEM’s workflow acceleration is unparalleled, delivering best-in-class performance.

VisLM's True Peak meter displays True Peak values as defined in ITU-R BS.1770. This accurately pre-empts and measures inter-sample peaks, allowing you to avoid potential distortion further downstream. 

VisLM logs True Peak violations against your project time code in the scrolling history view, and navigable flags allow you to quickly identify problem areas on the timeline.

VisLM is an ideal tool for loudness harmonisation between audio from multiple sources, consistently balancing music, dialog and special effects, and hitting specifications easily and intuitively. Whether working to meet legislation or simply towards internal loudness standards, VisLM’s workflow is rapid and objective.

VisLM also includes up to 7.1.2 surround support, and is PlayStation & Xbox One compatible.

Loudness Toolkit has been included in the audio tool category of Netflix’s Post Technology Alliance.
