Hear the future of television audio#
Visitors to Fraunhofer’s IBC booth will experience a technology preview of Fraunhofer’s new TV audio system being considered for upcoming television standards such as ATSC 3.0. The system is based on MPEG-H Audio, the open ISO standard which includes object-based audio that allows viewers to adjust the sound mix to their preferences, boosting hard-to-understand dialogue or creating a “home team“-mix of sports broadcasts.
The system also uses MPEG-H Audio’s ability to transmit immersive sound with additional front and rear height speaker channels, improving today’s surround sound broadcasts to provide a truly realistic and immersive audio experience. The system is based on a new, efficient audio codec that includes processing to offer an optimized experience with controlled loudness on every device over broadcast, cable, Internet, and mobile networks.
Fraunhofer will showcase their conceptual prototype of a sound bar that delivers high-quality 3D audio without requiring complex equipment, multiple external speakers or complicated external wiring.
Fraunhofer Cingo® - Mobile Surround Sound#
With Fraunhofer Cingo your tablet or smartphone becomes a true surround sound theater. Plug in your earphones or use the built-in stereo speakers to watch movies in enveloping surround sound - even while you’re on the move.
Not only does Cingo enable an excellent surround sound listening experience over stereo speakers or headphones, it also provides existing stereo content with a more natural and clear sound.
In addition, Cingo includes loudness optimization for listening in noisy environments and improves the intelligibility of dialog and commentary.
The Google Nexus family of devices uses Fraunhofer Cingo for audio playback.
xHE-AAC – The audio codec of choice for digital radio and low bit rate streaming#
With its special features, xHE-AAC (Extended HE-AAC) effortlessly meets the requirements of digital radio and streaming applications where various signal types need to be transmitted at very low bit rates. The audio codec produces excellent sound for both music and speech, delivering constant high quality performance at bit rates between 6 and 64 kbit/s and above.
The first digital radio systems adopting xHE-AAC and therefore benefiting from its features is DRM (Digital Radio Mondiale).
At this year’s IBC, booth visitors will have the chance to experience how well the audio codec handles various signal types at changing bit rates: Whether it’s talk radio, music or a jingle, xHE-AAC delivers consistently high quality.
