NUGEN Audio VisLM 3 is the third generation of NUGEN's loudness meter, built for audio post, broadcast, podcasts and game audio. It runs as AAX, VST3, AU and AudioSuite (64-bit) on macOS and Windows, and measures to ITU-R BS.1770 (revisions 1 to 4) with presets for ATSC A/85, EBU R128, Netflix, Amazon Studios, Disney, Sony, ARIB TR-B32, OP-59, DPP, Leq(m), Apple Podcasts and more. True Peak measurement flags inter-sample peaks.
The core of VisLM is ReMEM, which stores up to 24 hours of loudness data locked to DAW timecode. The history view is navigable, and when you replay a section after a mix change, the Integrated measurement updates automatically without an end-to-end re-measure. Loudness overdub and faster-than-real-time AudioSuite measurement complete the post workflow.
Version 3 adds linked stem monitoring, so instances on dialogue, music and effects stems report together in one window, plus LDR (loudness-to-dialogue ratio) measurement, timestamped notes on the history graph shared via CSV, Loudness QC Report export, new EBU R128 Supplement 4 and ATSC A/85:2026-07 presets, and 9.1.6 support. Optional 3D and DSP extensions are sold separately.
Against iZotope Insight 2, Youlean Loudness Meter 2 and Mastering The Mix LEVELS, VisLM 3 is the delivery specialist: it costs more, but it is the one built around timecoded programmes, dialogue specs and compliance reports. It is $499, or $249 to upgrade from any older VisLM. Our VisLM 3 first look covers every new feature, the specs and a full comparison.
