APT focuses on audio over IP at Broadcast Asia

Audio Processing Technology (APT), the Belfast-based audio compression specialist, will be focusing on the transport of broadcast quality audio over IP at this year’s Broadcast Asia Convention in Singapore.
Cost-effective and efficient, the ability to transport audio over IP is becoming increasingly sought after by radio and television networks and APT’s WorldNet Series of audio codecs are enabling broadcasters worldwide to make the switch.
All APT codecs incorporate the Enhanced apt-X algorithm; a low delay, non-destructive coding technology which is highly suited to the transportation of audio over IP networks for AM, FM, DAB, HD Radio and 5.1 applications.
One of the main attractions at APT’s booth at Broadcast Asia will be the new WorldNet Chicago Lite offering digital audio over IP for bidirectional stereo audio transport.
The competitively priced WorldNet Chicago Lite boasts an intuitive, user-friendly GUI for easy management and monitoring as well as contact closures and opto-couples for remote status and alarms.
Also making its Asian debut at the show will be the IP transport option for the highly acclaimed WorldNet Oslo. Having established itself as the codec of choice for multi-channel audio applications, APT’s WorldNet Oslo enables the transport of high quality content over an E1, T1 or IP link. With a unique feature set, incorporating Enhanced apt-X coding, the unit delivers real-time, near lossless quality audio on up to 24 channels.
There has also been innovation with regards the audio capabilities of the WorldNet Oslo resulting in the launch of the new simplex Quad Cards and 5.1 Phase-locking feature at Broadcast Asia. The Quad cards enable high-density audio transport with the ability to send up to 24 mono or 12 stereo channels on a single chassis while the 5.1 phase-matching feature, unique to the WorldNet Oslo, delivers true audio fidelity for surround sound contribution and distribution projects.
With such a wide and ever-expanding range of options, WorldNet Oslo will fit into a wide range of broadcast applications today and provides scalability and reliability for those seeking a future-proof solution.
The Broadcasters’ favourite WorldNet Rio audio codec is now available with an optional E1/T1 interface. The increased affordability and availability of fractional E1 and T1 connections has led to an increase in demand for these interfaces so APT have added these to the available options on the unit. The WorldNet Rio is a full duplex, multi-channel, multi-algorithm audio codec using both Standard and Enhanced apt-X. WorldNet Rio has been designed to deliver high quality audio for inter-studio networking, remote/outside broadcasts and STL applications.
The groundbreaking apt-X algorithm is recognised worldwide as providing the highest quality audio and has achieved international penetration in the realm of professional audio. The ability to operate within bandwidth requirements, combined with a unique resilience to bit errors and with minimal delay means apt-X is ideal for applications such as; wireless headphones, wireless 5.1 surround and wireless microphones.
For Broadcast Asia, the company will be presenting the Enhanced apt-X algorithm in multiple formats: Motorola DSP, TI, ADI, Verilog and ARM7. With potential applications in all areas of high quality consumer and professional audio, Enhanced apt-X licensing options will be available to third party manufacturers wishing to secure a lead in the market.
