The AAC-ELD algorithm allows full-fidelity, high-quality audio transmission at a data rate that easily fits into satellite and 3G wireless upload channels

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

The new algorithm will make its Comrex debut the upcoming National Association of Broadcasters show in Las Vegas.

Comrex Technical Director Tom Hartnett explains, "AAC-ELD 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 suited to real-time audio transmission over IP circuits".

Hartnett said "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 50ms".

Kris Bobo, Managing Director of Comrex said "AAC-ELD is free to current owners of the Access AAC Option".

"It is currently available for Access Rack and will be available very soon for Access Portable".
