With detailed, objective loudness measurement, history and logging facilities, VisLM provides a simple, ITU, ATSC and EBU standard compliant* way to measure, compare and contrast loudness during production, broadcast and post production, on the fly or for entire sections of audio.

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)
