Stagetec loudness metering for Aurus and Crescendo desks

Stagetec has extended the functionality of its Nexus-based Aurus and Crescendo audio consoles with with new loudness metering – allowing loudness values to be exported for long-term logging and legal audit trail.

‘In broadcast, where our systems are in common use, the importance of loudness metering is increasing,’ says Stagetec International Sales Manager, Sam de Pauw. ‘Our new interface to the most sophisticated loudness logging system on the market today significantly eases the burden of documenting and analysing loudness measurements for our customers.’

Salzbrenner Stagetec MediaGroup unveiled the first integrated loudness metering for Nexus 12 months ago, allowing each Nexus Base Device to provide simultaneous and independent metering for three audio programmes with up to eight channels each. The new Nexus software includes loudness metering in accordance with the American ATSC RP A/85 as well as with the international ITU and European EBU recommendations and enables external peripherals to be eliminated.

The software provides three loudness integration options – Momentary Metering with an integration time of 400ms, Short-term Metering with an integration time of 3s, and Integrated Metering with custom integration time, which enables Loudness Range (LRA) to be calculated natively within the Nexus. The results of the Integrated measurement can be inserted directly as metadata into a Dolby E stream or, with the help of the interface, stored for later use.
