Next Generation Audio is key to modern Ultra HD productions sound and opens up a whole new acoustical perspective for the listener. While enabling the content creator to place sound in a virtual 3D-soundfield, it not only yields its advantages for listeners with complex loudspeaker setups. Instead, it also offers the possibility to instantly adapt to any playback format, from higher order immersive sound to down-mixed stereo or even mono mixes. And it provides additional services like language selection and voice amplification to increase speech intelligibility. With the MMA the broadcasters and content providers are enabled to author and monitor even the most complex mixes to create a thrilling, yet easily accessible end-user listening experience. The system is enabled for loudspeaker setups ranging from one mono output to up to 7.1 surround and 4 overhead loudspeakers (7.1+4H), fulfilling all current MPEG-H 3D Audio requirements and configurations.

Jünger Audio – number one MPEG-H partner
Jünger Audio was chosen as trusted technology partner for the FRAUNHOFER IIS MPEG-H audio project.
Employing FRAUNHOFER’s MPEG-H audio authoring algorithms, the MMA is the basis for the MPEG-H audio demonstrations worldwide, aiding the MPEG-H Audio Alliance to convince broadcasters and standardization committees of the advantages of the MPEG-H Next Generation Audio and TV format. MPEG-H eventually was chosen to be part of the ATSC 3.0 standard and is now getting adopted by many countries and stations.

Authoring and Monitoring – Live and direct
The Jünger Audio MMA provides all tools required to handle and create static as well as dynamic audio channels and objects, author metadata and measure the loudness of each of the possible MPEG-H presentations. The monitoring unit also allows for listening to each dynamic range control (DRC) profile and individual channel downmixes. It also offers full supervision over interactive user-content to guarantee comprehensive quality control. All tools are tailored to work in real-time, enabling the operator to easily handle even the most complex tasks in a live-production. Interactive control of 3D audio objects can be obtained with a dedicated 3D-panner, a 3D-mouse or simply by entering detailed coordinate parameters. 3D-audio objects can be displayed in a customizable 3D-workspace offering graphic feedback to maintain perfect overview even with high object counts.

Easily accessible
Jünger Audio’s user interface fully relies on common internet technology and is accessible through a standard web browser. It follows a strict HTML5 only policy, avoiding any need for additional browser plug ins and keeping the control interface independent from operating system choice. The user interface provides full access to all configuration parameters, metadata and status information as well as interactive panning control for positioning 3D-objects in a virtual three-dimensional space.

Metering and Loudness measurement
Derived from our renown D*AP loudness processor range, the MMA provides a comprehensive set of loudness measurements for all channels, objects, output busses and formats. Obtained loudness data can be used to add correction values to the metadata stream, enabling the decoder to play back audio signals compliant to international loudness regulations. All metering data can be logged and analyzed externally with our J*AM Application Manager software.

Level Magic – Industry Leading Loudness Control
To provide a pleasant and exciting listening experience loudness control is inevitable. With its Level Magic technology, Jünger Audio is industry leading in transparent loudness correction. Based on a unique multi-loop design principle, Level Magic provides adaptive wideband loudness control with exceptionally high audio quality. The system works without filtering and band separation, avoiding crossover distortion and providing an output signal free of coloration, phasing and pumping or other modulating effects. The MMA is equipped with independent Level Magic instances for all input channels and objects. Its simple and fast preset based setup makes Level Magic™ a true set-once-and-forget tool.

Comprehensive I/O
The Jünger Audio MMA can be equipped with a comprehensive range of input and output interfaces. The standard configuration provides 3G and HD SDI interfacing with integrated video and audio delay to maintain lip-sync. Utilizing four 3G SDI cards enables full 4K processing, also including video and audio delay. To provide full access to network based audio workflows, the system can be equipped with network interface, making it fully compatible to the AES67 audio over IP and Ethernet standard. Additionally MADI, AES3 (AES/EBU) and analog audio interfaces are available.
