(click thumbnail)Comrex signed with Fraunhofer IIS to license the new AAC-ELD (Enhanced Low Delay) coding algorithm for use with its Access line of audio codecs.

It said the algorithm combines the best aspects of low-delay audio coding with Spectral Band Replication to reduce bit rate.

“This combination creates a coding algorithm that is uniquely suited to real-time audio transmission over IP circuits,” Technical Director Hartnett said in the announcement.

“Combined with BRIC Technology on Access, using AAC-ELD allows full-fidelity, high-quality audio transmission at a data rate that easily fits into satellite and 3G wireless upload channels.”

One-way Access transmission delay using AAC-ELD is an “easily managed 50 milliseconds,” he said.

The algorithm is offered as part of the AAC Option package for Access codecs and is free to current owners of that option. It is available now for rack systems and is planned for Access Portable.

The codec, HD-AAC, offers music encoding "with quality beyond CDs and at the same time, iPod compatibility." The company said the codec is based on the MPEG-4 SLS standard and provides lossless compression of 24-bit quality music content.
