Loudness metering is about to be adopted by most broadcast companies and post-production studios around the world as the new standard. However, real-time Loudness calculation still constraints mixing engineers and Broadcast operators to achieve a continuous project playback, without stops nor rollbacks to keep relevant loudness values. This method can be time-consuming when only a few areas of a mix require to be modified to stay fully compliant with the recommended level, as it requires to start the whole project measurement over.
Trinnov definitely solves this equation by slaving Loudness measurements to the incoming Timecode. This unique and elemental feature is making real-time loudness metering more effective and intuitive, and is therefore helping users to save a precious time in their everyday’s workflows.
The Integrated Loudness and LRA measurements both rely on a constant knowledge of the entire program content. Trinnov SmartMeter v4 records and time stamps every loudness and true peak values throughout the session, allowing their calculation at any time and therefore continuously providing consistent loudness measurements all along different mixing stages. Operators no longer have to manually pause, resume or even start measurements over.
The SmartMeter V4 supports multiple software sources with individual measurement and input format. The number of sources is only limited by the number of physical inputs and the processing power of the platform. Industry standards from mono to 7.1 are supported as well as custom formats up to 24 channels.
Thanks to the Time Code synchronization, measurements actually remain consistent with all the other elements of the project. As for video, audio or console automation, Trinnov implemented sessions recall. The whole project, including every sources measurements, alerts and user settings can be saved and recalled to resume mixing in another room and/or at a different time.
Session-specific thresholds can be chosen from the standard alert profiles (EBU R128, ATSCA/85, CST RT17, ARIB TR B32…) or user-defined to comply with delivery requirements of most organizations and companies.
Dynamic Alert Display
Overrunning the session thresholds trigger visual alerts and real-time logging. Alerts and logs are updated as the mix is adjusted. The alerts table can be filtered to display the alerts of a specific source and/or type of alert. Users are notified about LTC drops and therefore potential measurement errors. Alerts can also be transmitted to a server as SNMP traps.
Complete PDF reports are saved with the session, providing project information, the compliance status of each source with regards to the selected aler t profile and the list of alerts with their respective time codes.
The Multiview-Mode is a customizable display for MC Processors that gives the user great flexibility on how to arrange and access any of the 15 instruments and/or menus on a 4×4 split interface optimized for touch screens. Except for the DRC module, every instruments can have up to four independent instances simultaneously displayed.
