VisLM

The most fundamental question in audio production, how loud is it? Simple and yet elusive, with loudness inconsistency and incompatibilities present every day in broadcasts across the world. 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. These parameters are 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).
