Dynamics processing specialist Jünger Audio, based in Berlin, Germany, has introduced a number of new features to its Level Magic automated audio loudness control system for production and broadcast. These new additions enable Jünger Audio to offer an integrated workflow solution for managing Dolby coded 5.1 audio signals in production, ingest and playout.
Jünger Audio’s Level Magic is a sophisticated 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 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 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.
