Fraunhofer Cingo brings immersive audio to VR devices and applications with a stunning level of realism to create the experience of “being there”. With more than 25 years of experience in the field of audio coding and processing, Fraunhofer IIS is a driving force in the industry in the development and delivery of truly immersive sound on VR devices, smartphones and tablets.
Cingo renders 3D audio content over headphones by incorporating head movements and as a result, sound sources can be perceived from anywhere in the 3D space around the listener. A truly immersive soundscape is of utmost importance in any VR experience and serves as a determining factor in the success of the illusion. The MPEG-H audio standard is the ideal companion for Cingo 3D audio rendering with the ability to deliver immersive 3D sound for virtual environments to mobile devices at bitrates used today for delivery of 2D surround sound. MPEG-H can carry channels, audio objects and higher-order-ambisonics signals. This capability makes it the ideal VR audio codec for user generated and Cinematic VR content, providing a complete toolset of VR audio mastering and mixing plugins from Fraunhofer.
In addition to immersive sound, Cingo also enables an excellent surround sound listening experience over stereo speakers or headphones while providing existing stereo content with a more natural and clear sound. It includes features such as loudness optimization for listening in noisy environments and improves the intelligibility of dialog and commentary. Fraunhofer Cingo is used by industry leaders such as Google in its family of Nexus devices, Samsung Gear VR, LG 360 VR, and in the Hulu VR app.
MPEG-H Audio enables immersive and interactive sound in next-generation UHDTV broadcast systems, such as ATSC 3.0. With MPEG-H Audio, broadcasters and streaming services can deliver the future of video streaming and TV audio at comparably low bit rates in a cost-effective manner.
The MPEG-H Audio system is designed to work with today’s broadcast and streaming equipment and is part of the ATSC A/342 Candidate Standard. Features including object-based and immersive audio allow viewers to adjust the sound mix to suit their preferences, improving the level of realism for the overall audio experience. MPEG-H Audio will also tailor sound for optimal playback on a range of devices and environments, providing “universal delivery”.
Explore the full potential of digital radio applications when you visit Fraunhofer’s booth at this year’s IFA. The new Emergency Warning Functionality (EWF) for Digital Audio Broadcasting (DAB/DAB+) and Digital Radio Mondiale (DRM), is a simple and reliable tool that quickly provides the public with emergency information when disasters and emergencies strike. The EWF technology transmits audio messages in emergency situations, and also provides detailed multi-lingual textual information to assist non-native speakers and hearing-impaired users. In the event of an emergency, EWF-enabled digital radio receivers automatically re-tune to the emergency program or wake up from stand-by mode and broadcast the emergency warning.
Booth visitors will also have a chance to learn more about the Fraunhofer MultimediaPlayer for DAB/DAB+ and DRM. Aside from playing back stereo and DAB surround sound, the software supports program-associated data services such as EPG and Categorized Slideshow. Hybrid applications are possible thanks to Journaline’s Hot-Button feature.
Fraunhofer will also present maritime applications for DRM. For instance, marine weather forecasts and nautical services for recreational navigation and small commercial vessels as well as infotainment content for the Germany Navy overseas.
With its special features, xHE-AAC (Extended HE-AAC) effortlessly meets the requirements of digital radio and streaming applications where various audio content types need to be transmitted at very low bit rates. The audio codec produces excellent sound for both music and speech, delivering high quality performance at bit rates starting as low as 6 kbit/s. Thus xHE-AAC streaming apps and streaming radio players may switch to very low bit rate streams and offer a continuous playback even while the network is congested. It also opens up the possibility to reach billions of 2G users with music streaming services for the first time especially in emerging markets such as India. Streaming service providers benefit from drastically reduced CDN cost, while consumers enjoy an improved service quality while saving on their precious monthly data allowance.
DRM (Digital Radio Mondiale) is the first digital radio standard to adopt xHE-AAC and therefore benefiting from its features.
At this year’s IFA, booth visitors will have the chance to experience how well the most advanced audio codec (xHE-AAC) for radio and streaming handles all types of content at lowest and dynamically changing bit rates.
