Established world-wide for TV broadcast and streaming applications
Over the last couple of years, HE-AAC has become one of the most important enabling technologies for state-of-the-art multimedia systems. Thanks to its unique combination of high quality audio, low bit rates and audio-specific metadata support, it is the perfect audio solution even over channels with limited capacity, such as those in broadcasting or for new adaptive streaming standards such as MPEG-DASH.
Fraunhofer IIS offers fast access to high quality, product ready HE-AAC implementations. Optimized encoder and decoder real-time implementations on embedded processors or DSPs are available, as well as software implementations on PC platforms.
HE-AACv2 is the mandatory stereo codec in the DASH264 Interoperability Guidelines developed by the DASH Industry Forum. HE-AAC 7.1 has also been selected as one of the optional multichannel codecs.
- ... the most efficient high-quality multichannel and stereo audio codec.
- ... is used in TV, radio, and streaming worldwide.
- ... the perfect codec for adaptive streaming, for example Apple HLS or MPEG DASH.
- ... in more than ten billion devices already today.
- ... fully compatible with all relevant broadcast metadata.
- ... is supported and maintained by Fraunhofer IIS.
