Audio codecs simplify multimedia SoC design
The new MIPS Consumer Audio Platform provides easy access to a range of audio codecs developed by Fraunhofer IIS for implementation in multimedia system-on-chip applications.
Update for surround-sound software
The Fraunhofer Institute for Integrated Circuits IIS and Thomson have added two new elements to their MP3 Surround demo software.
MPEG Surround is a new, feature-rich standard compression technique for multichannel audio signals.
Operating on top of any core audio codec such as AAC, HE-AAC and MPEG-1 Layer II, the system provides a set of features including full backward compatibility to stereo equipment and a wide scalability in terms of bit rate used for describing the surround-sound image.
In combination with HE-AAC, MPEG Surround can carry a five- or seven-channel surround program at a total bit rate of 64Kbit/s or less.
The compatibility enables an easy upgrade path for existing stereo broadcasting and other media services to a more desirable surround-sound listening experience.
Specifically for portable applications, MPEG Surround offers a binaural mode, providing spatial rendering and reproduction of multichannel audio on stereo headphones.
All parties interested in capitalising on the benefits of MPEG Surround can obtain the MPEG-D standard document IS 23003-1 describing the MPEG Surround technology.
The MPEG Surround logo is available through the four developing parties.
MPEG Surround is being demonstrated at the 3GSM World Congress in Barcelona by Coding Technologies in hall 2.1, stand B37, and by Fraunhofer IIS in hall 2 , stand A126, from 12th to 15th February.
