VisLM is a Loudness Metering solution. It is fully compliant with the latest loudness standards ITU-R BS1770 and EBU R128 and offers a complete professional solution to loudness and true peak metering for Mix, Mastering, Film and Broadcast.

VisLM introduces several essential parameters for audio measurement:

• True-Peak level metering (inter-sample accurate level monitoring).
• Loudness Range (to help decide if and how much dynamic compression to apply).
• Momentary 'instantaneous loudness' for mixing by ear.
• Short term loudness (3 second time window).
• Program Loudness (long term integrated loudness measurement).
• Loudness distribution histogram.
• True-Peak maximum indicator.
• Short-Term/Momentary maximum value toggle.
• G10 gate option (ITU-R B.S. 1770-2 / EBU R128-2011 ready).
• ARIB (Japan) preset.
• Clearer memory selection display.

VisLM is available in two versions, VisLM-C (compact) and VisLM-H, which in addition to EBU mode metering provides a loudness history trace and data export.
