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.
The high audio quality provided by MPEG-4 AAC-LD and AAC-LC eliminates any telephone-like feeling from video conference systems and make conferences less exhausting and more pleasant to follow.
In addition to natural sounding speech and music, MPEG-4 AAC-LD features a low encoding/decoding latency together with low datarates.
All these features make the codec one of the most important audio coding technologies in today's video conferencing world.
MPEG-4 AAC-LD and AAC-LC are used in the Codian MCU 4200 and IP VCR 2200 series.
The MCU 4200 series is a conferencing bridge.
The IP VCR 2200 series is a digital recorder specifically designed for video conferencing.
Harald Popp, Head of the Multimedia Realtime Systems Department at Fraunhofer IIS, says: "As main developers of the powerful MPEG-4 AAC-LD and MPEG-4 AAC-LC audio standards, we are of course delighted to see that our software makes its way into Codian's video conferencing products".
Mark Loney, Director of Product Management for Codian, adds: "We are delighted to work with Fraunhofer to add AAC support to our products".
"This is an important part of our quest to support the best features of every videoconferencing endpoint".
"AAC allows us to fully interoperate with systems from Tandberg, Sony, LifeSize and Vcon".
