Waves Introduce WLM Loudness Meter

Fully compliant with all current ITU, EBU and ATSC specifications, the WLM offers comprehensive Momentary, Short Term, Long Term and True Peak readouts, plus a unique warning and logging system that keeps track of users' levels and lets them know when they have exceeded them – or fallen short. WLM offers foreground, dialog and average loudness measurements, and an intelligent dialog sensor detects and measures speech. The plug-in features mono, stereo and 5.1 components.

WLM Controls

• Short Term displays (in LUFS) perceived short term loudness.
• Long Term displays (in LUFS) perceived loudness averaged across the program signal.
• Range displays (in LU) the overall loudness range across the program signal
• Momentary displays (in LUFS) momentary loudness levels, according to the Momentary scale control settings.
• True Peak displays (in dBTP) inter-sample peaks that do not register in the sample data but may occur during reproduction of the digital signal.
• Unders displays the number of times the signal goes below the specified Short Term Min value indicated in the settings panel.
• Overs displays the number of times the signal exceeds the specified Short Term Max value indicated in the settings panel.
• Measurements Play/Pause determines if program loudness is registered in the WLM memory for averaging long term loudness range.
• Follow Transport determines if measurement starts and stops according to host application transport controls.
• Timer indicates the amount of time measurements that have been taken and integrated.
• Reset resets the Long Term, Range, Overs and Unders counters and returns the integration timer to 00:00:00.
