Las Vegas, NV (May 1, 2006)–Belfast-based APT and U.S.-based Pulsecom have enhanced their PCAU to support telco-based STL, Remote-to-Studio and Studio-to-Studio HD Radio services in North America. In other APT news from NAB2006, Source Elements LLC, a leading provider of software solutions for the Pro Tools environment, has signed a licensing agreement with APT to incorporate the apt-X algorithm in their plug-ins.
The new HD-PCAU (Program Channel Access Unit), officially launched at NAB2006, will assist broadcasters with their migration from analog to digital by offering an AES/EBU interface, the 20Hz-20kHz bandwidth needed to transport HD radio content and auxiliary data input/output allowing RBDS to be embedded in the audio stream. The incorporation of APT’s acclaimed, non-destructive apt-X data compression algorithm will also allow broadcasters to maintain audio quality right up to the point of final stage HD Radio emission.
The joint venture between APT and Pulsecom dates back to 2001; since its launch, over 3,000 Pulsecom/APT PCAU cards have been deployed thanks to its ability to deliver high quality audio with minimal processing delay over cost effective telco program audio circuits. The original card was designed to deliver AM (7.5 kHz mono) and FM (15kHz stereo) program content with analogue interfaces, rather than the AES/EBU interfaces more appropriate for digital radio. The new HD-PCAU card gives broadcasters access to all the benefits of the digital domain while preserving the maximum dynamic range and signal clarity that listeners are increasingly demanding.
Source Connect is a fully featured Pro Tools plug-in, which allows broadcast-quality audio to be transmitted between remote locations. Affordable, fully duplex and high quality link-ups between Pro-Tools users can be achieved with the Source Connect plug-in over a T1, cable or DSL internet connection.
