Dallas, TX (August 30, 2006)--APT will unveil the new WorldCast range of IP-based audio codecs for broadcasters at the NAB Radio Show in Dallas, on September 20-22, 2006. WorldCast Horizon and WorldCast Meridian are the first products in this new generation of APT audio codecs featuring IP connectivity as their core functionality.

"In recent months, a significant number of broadcasters and service providers have expressed interest in transporting audio over IP but have been reluctant to invest in new infrastructure," said Jon McClintock, APT's commercial director. "They needed to be sure that they weren't sacrificing the reliability and latency of their existing synchronous networks for the cost-effectiveness and efficiency of IP transport. The WorldCast Series enables these broadcasters and service providers to easily commence the migration to IP and still retain the same exceptional audio quality, low delay and DSP-based dependability for which APT codecs have become renowned."

The WorldCast Horizon offers digital audio over IP for bi-directional stereo audio transport. It operates using Enhanced apt-X coding technology which, thanks to its low delay and exceptional acoustic properties, is particularly suited to the transport of audio over packet-switched networks. Based on DSP architecture for 24/7/365 reliability, the WorldCast Horizon provides contact closures and opto-couples for remote status alarms. The unit comes complete with APT's powerful Network Management Software package for easy management and monitoring.

The new WorldCast Meridian is a fully duplex, multi-algorithm audio codec offering both IP and leased line connectivity. Users can choose from a suite of coding options including: Enhanced apt-X, G.711, G.722, MPEG Layer II, MPEG Layer III, AAC, AA LD and AAC LC.

At the NAB Radio Show, APT will also be showcasing several new features on the WorldNet Oslo audio multiplexer for Studio to Transmitter and studio networking links.

APT can be found at Booth 316 at the NAB Radio Show.
