Qualcomm Technologies International, Ltd. Launches Qualcomm® aptX™ HD

Qualcomm Incorporated announced that Qualcomm Technologies International, Ltd. launched Qualcomm® aptX™ HD, a newly enhanced codec that offers 24 bit music quality over a Bluetooth® wireless connection. Building on the existing aptX audio codec platform, which revolutionized the Bluetooth stereo listening experience, aptX HD is designed to enable audio manufacturers to meet the increasing demand for high resolution wireless audio. aptX HD is immediately available as part of the CSR8675 Bluetooth audio SoC platform which supports 24 bit audio end-to-end. As with aptX, aptX HD is designed to address the challenge of sending high quality audio wirelessly over Bluetooth by compressing the large audio files so that they can be transmitted through the wireless pipeline without affecting the listening experience quality. To ensure a seamless consumer experience, and to interact with the millions of aptX enabled devices already available, the enhanced codec retains backward compatibility with all Bluetooth devices containing 'classic' aptX. aptX audio technology has a long history in the pro-audio and broadcast ecosystems. The technology is used to deliver high quality audio in over 30,000 radio stations and 20,000 cinemas across the world. In 2009, aptX was introduced to consumer electronics to provide quality wireless audio – and has been adopted by over 320 leading audio brands making it available in millions of headphones, speakers, soundbars, automotive and other Bluetooth audio products worldwide. It's also widely enabled in mobile devices and is now available in Android smartphones and tablets from Samsung, Sony, HTC, Motorola and LG, as well as in other operating systems including Windows 10, MAC OS X and Blackberry.
