Harald Fuchs (l.), Fraunhofer IIS, wins NAB Technology Innovation Award 2012 for “Dialogue Enhancement”Berlin, Germany (August 31, 2012)-Fraunhofer Institute for Integrated Circuits IIS has launched its next generation video telephony audio codec, Enhanced Low Delay AAC (AAC-ELD).
The new codec reportedly delivers CD-like audio quality and paves the way for SmartTVs as primary communication devices in the living room. AAC-ELD is the only widely adopted Full-HD Voice technology.
“Thanks to our AAC-ELD software, communication apps for SmartTVs will allow for conversations at a level of audio quality which so far has been limited to high-end video conferencing or telepresence systems,” says Harald Popp, head of the Multimedia Realtime Systems department at Fraunhofer IIS. “As AAC-ELD is already part of all leading smartphone operating systems, including iOS and Android, it is high time to finally introduce Full-HD Voice quality to the living room.”
Full-HD Voice is the highest audio quality standard for communication applications. Whereas legacy telephony is restricted to an upper limit of 3.4 kHz audio bandwidth, Full-HD Voice capable audio codecs support audio bandwidths of 14 kHz and more.
AAC-ELD is a communication codec based on the commonplace music codec AAC, which is used by major music download and streaming platforms. AAC-ELD provides CD-like audio quality for video and telephone calls at very low bit-rates. Thus, most professional video conferencing, telepresence systems, as well as consumer video telephony applications such as Apple FaceTime, rely on AAC-ELD.
