WLM Plus measures loudness to all current ITU, EBU and ATSC specifications, so your audio hits its target levels for streaming, broadcast and other media.

The meter complies with ITU-R BS.1770-3, EBU R 128 and ATSC A/85 and displays Momentary, Short Term, Integrated and True Peak values. Choose between the EBU measurement methods, LM1 and DIAL, which uses dialogue as the loudness anchor. A True Peak limiter and gain trim fix levels right inside the plugin, presets cover common requirements, and CSV log files document the readings of all three methods simultaneously.
