LAS VEGAS - APTX is introducing Apt-X Lossless, its scalable, lossless audio coding scheme, here at International CES. It will be exhibiting in the LVCC South Hall 1, booth 20650.

According to the company, the technology "significantly outperforms conventional lossless audio coding schemes in use-scenarios that depend upon the efficient and reliable transmission of high-quality, multiple-channel audio over wireless networks."

In laboratory testing, the company found Apt-X Lossless offered a significant gain in compression ratio (up to 10 percent more data reduction) when compared with competing lossless audio codecs.

Dr. David Trainor, chief technology officer of APTX, said, "This new Apt-X Lossless audio compression scheme is the first of a new breed of scalable and adaptive audio compression solutions being developed by APTX that have the potential to elevate the quality of multichannel audio transmitted over wireless networks and mitigate many of the deployment issues traditionally associated with lossless audio coding in these environments. The superior performance of Apt-X Lossless under real-world system conditions that fluctuate widely over time - available processor power, remaining battery energy, variable channel bandwidth, changing radio propagation conditions, and other factors - has direct implications for the user experience.  This is an especially important consideration in the design of wireless-enabled multi-room audio systems for low-energy home installations."

APTX says that from a system integration standpoint, Apt-X Lossless is easy to port across multiple hardware and software platforms. The company said the audio codec is implemented as C and C++ code, and has already been verified on various processor architectures, including ARM, Texas Instruments C64xx, Intel x86 and others to be announced.
