apt-X audio coding apt-X audio coding Outstanding audio quality apt-X technology is what wireless audio has been waiting for. With apt-X audio coding, you can be assured of crisp, pure and full stereo sound. It allows you to not only hear, but experience and feel the audio as it was intended. Utilizing apt-X, Bluetooth can now offer wireless audio quality that is indistinguishable from the highest quality wired connection.
apt-X audio coding apt-X key features: • Blind listening tests with industry reference audiences have shown that apt-X over Bluetooth is indistinguishable from audio delivered over wired technology. Unlike psychoacoustic-based technologies such as MP3 or AAC, apt-X can be used to transport audio without degrading the audio quality. With MPEG/AAC compression, the encoding process is destructive and content perceived as “irrelevant” is discarded.
