Industry Standard Loudness Metering

Hit the target first time, every time, with VisLM’s instant overview combined with detailed historical analysis. Mix with the confidence and peace of mind you can only experience with an industry standard product.

With a full set of international and regional presets, VisLM is ready to go immediately. And for legacy, station specific or internal specifications, VisLM can be fully configured to handle any situation; from detailed expert reporting to simple safety zones and navigable loudness alerts for less experienced operators.


NUGEN loudness products are compatible with all recommendations and guidance based on the international standard ITU-R B.S. 1770, revisions 1, 2, 3 and 4 including:

• EBU R128
• EBU R128 S1
• OP-59
• AGCOM 219/9/CSP
• Portaria 354
• DPP (BBC, ITV, C4, C5, S4C)

VisLM also supports Leq(m) (TASA and SAWA variants) and Leq(a) measurements.

For Avid HDX hardware compatibility, the software is also available in a DSP version. Please note that the DSP version uses AAX Hybrid functionality, which is not yet supported by the HDX Hybrid Engine.
