Jünger Audio has begun shipping its Level Magic 5.1 solution for controlling loudness in production and broadcast with the new Upmix functionality. The company’s C8000 Level Magic system incorporates a suite of DSP and interface cards that enable it to manage surround-sound and Dolby-coded 5.1 audio signals in production, ingest and playout. These include HD/SDI de-embedding/embedding with VANC, Dolby E resynchronization with built-in video delay and Dolby metadata generation.
The introduction of the Upmix functionality effectively completes the chain, making it possible for broadcasters to resolve the interrupted surround-sound feeling while reproducing mono and stereo sources as well as maintain Upmix loudness consistency compliant with dialnorm and ITU specifications. The Upmix function takes a mono or stereo signal and filters the ambient information and spectral composition to create a proper 5.1 upmix.
