Fraunhofer Cingo® & MPEG-H for the best immersive sound experience on VR devices
Fraunhofer Cingo brings audio immersion to VR devices and applications with a stunning level of realism that creates the experience of “being there”. With more than 25 years of experience in the field of audio coding and processing, today Fraunhofer IIS is a driver for truly immersive sound on VR devices, smartphones and tablets. Cingo renders 3D audio content over headphones incorporating head movements, and thus 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 becomes a determining factor in the success of the illusion. The MPEG-H audio standard is the ideal companion for Cingo 3D audio rendering as it can deliver immersive 3D sound for virtual environments to mobile devices at bitrates used today to deliver 2D surround sound. Besides audio channels, MPEG-H can also carry audio objects and higher-order-ambisonics signals. This makes it the ideal VR audio codec for both, user generated content and Cinematic VR content. Fraunhofer is providing a complete toolset of VR audio mastering and mixing plugins.
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, as well as Samsung Gear VR.
Enhanced Voice Services
Enhanced Voice Services (EVS) is the next-generation 3GPP VoLTE codec, successor of AMR-WB. EVS enables phone calls with Full-HD Voice quality, bringing call fidelity up to the same level as today’s other digital media services. Integrating state-of-the-art speech and audio coding technology, EVS removes the limitations of bandlimited, voice-centric codecs previously used in mobile communication. The algorithm enables high quality speech, background music and mixed content with the full audible audio spectrum at unmatched low bit rates. Combined with EVS’ advanced robustness against packet loss, the algorithm results in clear, natural sounding conversations and vastly improved performance of hold music and ring back tones.
