xHE-AAC represents the next step in audio codec technology.
“We are taking a new approach to live streaming with the application of Fraunhofer’s xHEAAC codec enabling the StreamS Live Encoder.

The StreamS Live Encoder is the first professional streaming encoder supporting xHEAAC. We are excited that Internet streaming services enabled by xHE-AAC will now even further improve the listening experience and help bring radio programs for the first time to billions of mobile users in emerging markets that still to a large extent, rely on 2G networks,” says Bernhard Grill, head of the Audio & Multimedia division and deputy director, Fraunhofer IIS. “The mp3 format enabled the first Internet music services, the HE-AAC codec brought Internet radio to billions of mobile users. The listening experience especially for users of mobile devices gets improved by reducing buffering times and an increased service reliability, while the lower bandwidth requirements reduce CDN costs for program providers and prevent data plan overflows at the consumer end. The coding efficiency of xHE-AAC enables streaming services to operate at lower data rates, resulting in major benefits for consumers and program providers. At the IBC 2015 show there was a unique chance to compare how really efficient audio compression algorithms have become, from mp3 and ogg-vorbis to AAC, HE-AAC and the new xHE-AAC, optimized for speech and music transmission with very low bit rates.ĭesigned for speech and music transmission at only 16kbit/s for stereo, xHE-AAC is the low bit rate extension of the AAC audio codec, the worldwide industry standard for streaming, broadcast and music distribution (e.g.
