What VisLM is
VisLM is a loudness meter for audio production workflows on Windows and macOS. It supports real-time and offline file analysis, measuring true peak, momentary, short-term, and integrated loudness along with Leq(m) and Leq(a). Its ReMEM feature stores up to 24 hours of loudness data against project timecode and refreshes readings after edits or overdubs; full ReMEM operation requires timecode lock from the NLE or DAW. VisLM supports up to 7.1.4 surround and is compatible with PlayStation and Xbox One. Listed standards include ITU-R BS.1770, EBU R128, the CALM Act, and Netflix recommendations. The 64-bit formats are AAX, VST3, AU, and AudioSuite, and a standalone application is available for Windows and OSX. NUGEN identifies post-production, acquisition, broadcast, and game audio as typical uses. Pricing starts at $49/mo, with a VisLM plan listed at $449, paid once. A fully functioning demo is limited to 15 days. Licensing options include iLok and challenge-response methods.
