Audio Technology Highlights by Fraunhofer IIS at AES 2023

AES New York 2023

Booth 722

At AES 2023, Fraunhofer IIS showcases a range of innovations that take the sound experience to the next level. From creation to transmission and all the way to playback: tools, technologies, and codecs by Fraunhofer IIS ensure maximum music enjoyment, highly efficient and flexible data transmission, and creation for several production formats.

^{xHE-AAC: the Latest Generation of AAC}

xHE-AAC is the latest generation of the renowned AAC codec family and now part of the Sonnox Fraunhofer Pro-Codec. Users of Sonnox can now audition and encode their creation in xHE-AAC in real time, giving audio professionals the option to pre-monitor the effects of codecs on their signals. XHE-AAC is already used by major streaming services such as Netflix and is natively supported in iOS, Android, Fire OS, and Windows. It provides DASH/HLS streaming at 12-500 kbit/s, mandatory loudness and dynamic range control, and improved speech quality as well as stereo imaging.

^{MPEG-H Authoring Suite – a complete MPEG-H Audio Tool Chain for free}

Tools for contemporary Next Generation Audio workflows have never been this easy:

Discover the MPEG-H Authoring Suite! The complete MPEG-H Audio tool chain makes possible the authoring, encoding, and playback of your immersive, interactive audio production. It now includes an 8K video and immersive audio player, supports ADM-based production formats, and enables the conversion of Dolby Atmos to MPEG-H Audio.

Come to our booth and get a hands-on experience of MAS and the other MPEG-H tools available for the entire production chain.

^{LC3/LC3plus: High-quality Audio for the Entire Communication Ecosystem}

The new LC3/LC3plus audio codec was jointly developed by Ericsson and Fraunhofer IIS to address the drawbacks of today's wireless communication platforms. The low complexity of the codec meets the requirements of wireless communication platforms such as Bluetooth, DECT, and VoIP terminals. By reducing the required bit rate by about 50 percent compared to older codecs, LC3 and LC3plus enable energy-saving services that make a longer battery life or the development of smaller products possible. Thanks to the flexible codec design, applications are not limited to voice services, but can also be extended to high-quality music streaming. At the same time, the codec operates with low coding delay, low computational complexity, and small memory requirements.
