The recommendation R128 was published by the EBU in August 2010, soon establishing nowadays broadcasting practice for audio measurement and normalisation using Loudness meters instead of Peak Meters (PPMs).
Even though measurement methods and delivering requirements vary much from a country/organisation to another, a target “Integrated Loudness” level is almost systematically specified.
Trinnov’s unique approach to Loudness
Most common loudness “live meters” require to measure a project from beginning to end without rollbacks or time jumps to obtain its Integrated Loudness level. Even if pausing is possible with most instruments, this method is definitely not ideal.
Trinnov unique Time Code-aware SmartMeter takes loudness metering to a new dimension. The measurement automatically starts and pauses following the playback system, continuously providing consistent values, whether the operator jogs, shuttles or rewinds through the project.
Another huge advantage of Time Code synchronization is the possibility to trigger real-time alerts and update them as the mix is adjusted. Alerts thresholds can be configured to meet requirements of any organisations and/or companies.
Having Loudness and Peak values stored and time-stamped also makes session recall relevant. Projects can be paused, shared over a network and resumed in other studios in the actual very same conditions.
Trinnov powerful platforms allow Loudness and True Peak measurements to be activated independently for multiple user-defined sources.
Multichannel platform users can cutomize their workspace and save custom layouts in presets.
