AUDIO Processing Technology (APT) has signed a five-year licensing agreement with DTS through which it will license its apt-x algorithm for use in all DTS's professional cinema sound systems.
DTS has been using APT's integrated circuits in its cinema systems since 1993 but this new deal represents the first time APT has licensed its digital audio compression technology in DSP (digital signal processor) code format to the company.
Noel McKenna, managing director of APT said that the deal guaranteed the future of apt-X in DTS professional cinema systems: "Our DSP code provides DTS with a flexible alternative to conventional integrated circuits and allows them to incorporate APT's apt-X algorithm into their systems in a more efficient way. By incorporating the apt-X algorithm, DTS can implement five channels of apt-X decoding within the one DSP, therefore reducing the overall hardware requirement in the playout system."
John Kirchner, President of DTS, added: "The new licensing agreement is as a result of our success in the cinema industry and our commitment to develop new products using APT technology."
At the forefront of digital audio compression technology, APT has a global customer base encompassing the world of professional audio through international broadcasters, telecommunications companies, local and national radio stations and post production and music studios. OEM partners provide products ranging from radio automation system, cinema surround sound systems and automated public address systems.
The company is now actively licensing its apt-x algorithm in software format for both PC and DSP platforms in order to eliminate previous hardware constraints. On the PC platform the algorithm is known as SOFT apt-x.
This new technology is based around the original 16bit algorithm, supplied as a core .DLL that can be seamlessly integrated into a wide variety of software applications.
SOFT-apt-X delivers the key benefits of the original algorithm, including outstanding audio quality, negligible coding delay and immunity to multiple encode/decode cycles.
