This technology white paper introduces the reader to an entirely new scheme for lossless audio compression called apt-X Lossless. This scheme has been conceived, designed and developed by APTX, a pioneering audio processing technology company, the commercial originator of the apt-X low-latency audio codec, and a venture-funded, private company with a long and profitable association with both the broadcast industry and the studio post production business. Briefly and simply, by employing dynamic adaptation techniques to a greater and more intelligent extent than conventional schemes, apt-X Lossless, offers significant benefits over existing lossless audio codecs, and attains better coding scalability and run-time trade-offs as a result.
