Fraunhofer IIS-A and Telos Systems to Debut MPEG-4 AAC-LD Audio Codec at NAB 2001
Summary
Fraunhofer Institute, primary inventor of MP3, and Telos Systems announced a joint press conference at NAB 2001 to demonstrate MPEG-4 Low Delay Advanced Audio Coding (AAC-LD), a new audio compression standard offering MP3-quality sound with 80% lower transmission delay at 64 kbps. The technology debuts in the Telos Zephyr Xstream ISDN codec family, the world's first commercial implementation of AAC-LD.

MP3 inventor Fraunhofer Institute for Integrated Circuits IIS-A and Telos team to bring next-generation MPEG codec to the broadcast industry
Erlangen, Germany - Cleveland, OH, USA, April 18th, 2001 - Fraunhofer Institute, primary inventor of the famous MP3 audio standard, and Telos Systems, first implementer of MP3 in a product, invite you to their joint press conference at NAB 2001. Have a look at the "next MP3" demonstrated in an advanced ISDN codec system. The latest results of a fruitful collaboration begun in 1993, Fraunhofer and Telos will show you their most recent development - an advance potentially as important as was the introduction of MP3 to the broadcast and Internet worlds seven years ago. The new MPEG-4 system Low Delay Advanced Audio Coding (AAC-LD), developed by the Fraunhofer Institute for Integrated Circuits IIS-A, will be presented at NAB 2001. This new technology offers a breakthrough in the quality of audio transmission for telephone systems. At a data rate of 64 kbps, AAC-LD offers sound quality that is comparable to MP3, but with 80% lower transmission delay. Thus, this latest MPEG-4 audio standard is the perfect companion to ISDN and next-generation UMTS mobile telephone channels to enable high-fidelity audio transmission. It also makes possible conference systems with low delay and excellent quality. Telos Systems and Fraunhofer IIS-A are demonstrating the world's first implementation of AAC-LD in real products - the new Telos Zephyr Xstream ISDN codec family, which is being introduced at NAB 2001. The original Zephyr was first to use MP3, a feature that helped to make it the number one choice for sending broadcast quality audio over ISDN - and perhaps the most successful digital audio product in the radio broadcasting industry ever. Harald Popp (Head of Department, Fraunhofer IIS-A) and Steve Church (President, Telos) will give you detailed information and a demonstration of AAC-LD and the new Telos Zephyr Xstream. Further demonstrations will be offered at Fraunhofer's booth E 5847 at E-topia. Snacks and drinks will be served. Telos will be showing the new Zephyr family at their booth R 2263 throughout NAB 2001.
