Quantel is the latest in a growing list of video system manufacturer to integrate loudness technology into its products, supporting Nugen Audio metering on its broadcast editors. This upgrade will extend to include the company's post-production workstations in the next few months. The new V5.2 software release for Quantel's broadcast editing range now includes the Nugen VisLM loudness metering program, which complies with EBU R128, ITU 1770 and ATSC A/85. VisLM includes both real-time and faster than real-time analysis, as well as True Peak, loudness range, momentary instantaneous loudness for when operators mix by ear, short-term loudness and programme loudness. Quantel's marketing director, Steve Owen, explains that customers had been asking for loudness capability to ensure compliance with new standards being introduced in different countries. "Places like Germany now have federally mandated loudness requirements and people have to comply with them," Owen explains. "Our users are now able to finish a project in the Quantel system - and see they are hitting -23 LUFS or other targets - without having to put another step in the process." Previous Quantel editing systems have included audio metering, based on the PPM scale, to allow sound mixing to be carried out in the same workstation as picture cutting. Owen comments that the addition of loudness metering to Quantel's editors will allow operators to deal with any problems at the beginning of the production chain: "It's better to get it right early on rather than try to deal with a problem later. The new standards are part of quite a grand plan for dealing with audio and should make the TV experience better." Jon Schorah, creative director at NUGEN Audio, comments, "Tight integration into the heart of an editing system is the key to a fast and efficient workflow. By working with Quantel we will help ensure that essential loudness metering is seamlessly available across its entire range of broadcast editors." Owen says other loudness systems could be integrated into Quantel products but explains customers had mentioned Nugen and that this partnership provides the necessary technology for users right now. The VisLM program will also be included in the next software release for Quantel post-production editors, which Owen estimates will be by "probably the end of April". www.quantel.com
