Berlin, Germany (November 14, 2008)–Dynamics processing specialist, Jünger Audio, has introduced a number of new additions to its Level Magic automated audio loudness control system for production and broadcast.
The new additions reportedly offer an integrated workflow solution for managing Dolby-coded 5.1 audio signals in production, ingest and playout.
Peter Pörs, managing director of Jünger Audio, says, “Our aim is to offer an outstanding integrated workflow solution that incorporates signal monitoring and smart 5.1/2.0 fail over switching, including program metadata management. The new cards we have introduced draw on our 20-plus years of experience in dynamic-range processing and provide Level Magic customers with a solution that is far more effective than anything else on the market.”
Jünger Audio’s Level Magic is an adaptive, level-control algorithm that is designed to adjust the level from any source at any time, with no pumping, breathing or distortion. It is based on a simultaneous combination of an AGC, a transient processor for fast changes, and a “look ahead” peak limiter for continuous unattended control of any program material, regardless of its original source.
Capable of using any kind of I/O (analog and digital) sources, as well as SDI, HD/SDI, Dolby 5.1 and all its related metadata, Level Magic is available in a variety of configurations to suit different applications.
The latest addition to the range is the C8086-8, an 8-channel DSP card that incorporates a new Dolby Metadata Generator option. This is designed for use with the modular-frame C8000 system, which provides audio processing for a variety of applications including audio production, broadcasting, distribution, re-broadcasting and audio for video.
Level Magic can be configured and remotely controlled via a web interface, and it now complies with the ITU’s BS.R1770 loudness-control specifications as level detection can easily be switched to ITU mode.
When used in combination with Jünger Audio’s C8601 Dolby D/E decoder, C8611 Dolby E encoder, C8612 Dolby D/D+ encoder and C8404 HD/SD-SDI inserter, the new DSP card allows users to verify, modify or generate metadata, including Dialnorm, according to Dolby specifications for both Dolby E and Dolby Digital. The card also incorporates Dolby Metadata display and editing and eight Metadata presets. With the C8086 in place, the Level Magic system can transport metadata from the point of origin up to the point of Dolby Digital encoding, thus ensuring that the entire workflow for 5.1 audio production remains HD/SD-SDI embedded throughout.
“Program suppliers, including IPTV companies, are well aware of the problems caused by surprise level changes when switching from one source to another,” Pörs adds. “They are also equally aware of the annoyance this causes for viewers who have to rely on their remote control to adjust the volume between programs on different channels or between programs and commercial breaks.”
