The audio compression specialist argues its apt-X Lossless significantly out-performs other lossless audio coding formats in emerging application scenarios that depend upon the efficient transmission of high-quality audio over wireless channels and IP networks.
This conclusion, the company said, is based on performance data obtained from rigorous and intensive laboratory testing of apt-X Lossless against other types of lossless audio codecs using a set of industry-standard reference audio samples.
The company says improvements in performance demonstrated by apt-X Lossless relative to FLAC, for example, include a significant gain in compression ratio – up to 10% more data reduction – at time delays under 2 milliseconds.
This extremely low degree of latency (sub 2 ms) is of critical importance in applications involving video, interactive games, and 2-way communications, says APT-X.
Dr David Trainor, the architect of apt-X Lossless, said: “This research clearly shows that apt-X Lossless – the latest addition to the apt-X portfolio of scalable audio compression solutions – has the potential to elevate the quality of multi-channel 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 vary widely over time has direct implications for the user experience.”
