Dynamics processing specialist Jünger Audio has started shipping the new UPMIX functionality to its LEVEL MAGIC™-based 5.1 solution for controlling loudness in production and broadcast.

Peter Pörs, the company’s managing director, says: “We introduced UPMIX at IBC and have already received substantial orders from North and South America. The first units are shipping to Brazil this month. At the moment the software runs on a separate DSP card but in future it will be available as a simple plug-in that can easily be installed alongside LEVEL MAGIC into existing C8000 systems.”

The company’s C8000 LEVEL MAGIC system incorporates a suite of DSP and interface cards that enable it to completely integrate workflow for managing 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 resynchronisation with in-built video delay and Dolby Metadata generation. The introduction of UPMIX functionality effectively completes the chain, making it possible for broadcasters to resolve the interrupted ‘surround sound feeling’ while reproducing mono and stereo sources and also maintaining UPMIX loudness consistency compliant with Dialnorm and ITU specifications.

Pörs adds: “The new UPMIX function developed and introduced as a direct result of customer demand. Broadcasters, particularly those in the USA and Asia, recognised that with High Definition/5.1 installations on the increase there was a real need to resolve this problem. There are other products on the market that can sort out the upmix of stereo signals, but ours is the only solution that also delivers a dedicated scenario for mono sources as well as loudness consistency. We achieve this by linking UPMIX to our LEVEL MAGIC adaptive level control algorithm. In this way we are effectively sorting out two problems at once and helping broadcasters deliver a much better listening experience to their viewers.”

The UPMIX function takes a mono or stereo signal and filters the ambient information as well as the spectral composition to create a proper 5.1 upmix. The solution comes with a SURROUND CHECKER™ auto format detector, enabling the LEVEL MAGIC suite to identify the channel format of the signal and initiate adequate UPMIX or 5.1 processing.

We feel the negatives are known and are a lot more comfortable recommending the space.
