Reliable quality

Loudness compliance perfectly integrated into your workflow, using a clear resizable interface and groundbreaking ReMEM automated loudness memory technology.

• 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

Loudness memory

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. 

Comprehensive True Peak metering

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.

For post, broadcast & games

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 Production Technology Alliance. This is a programme for manufacturers that handles sound, image or metadata during the processes of production to postproduction. If the product meets specific criteria, it is considered as a candidate for the alliance. Any product that bears the alliance logo has been assessed to ensure that it meets with Netflix’s technical and workflow requirements.
