It operates on the same principle retaining all the key properties of aptX that have seen the codec so widely adopted. aptX HD is a further development of the existing classic 16-bit aptX codec. “The result is aptX HD, a newly enhanced codec that supports 24-bit music quality over Bluetooth.
“With that in mind we decided it was time to build on the existing Qualcomm aptX audio codec platform, which revolutionized the Bluetooth stereo listening experience by supporting CD-like quality audio over a wireless connection, in order to enable audio manufacturers to meet this increasing demand.

A quick glance around any consumer electronics trade show or department store will confirm that support for higher resolution audio is now a given across a wide range of products and services. Meeting the need for hi-resolution wireless audioĪccording to Steve Graham, vice president, product marketing, Qualcomm Technologies International,”Over the last two years, what started as a niche initiative in the high end audio market-the desire for hi-res audio-has gathered momentum across the ecosystem.
The technology will continue to evolve as we invest in further innovation to ensure it meets the future needs of our customers,” concludes Anthony Murray. “aptX was one of the first technologies to bring pro-audio quality to wireless consumer devices and has become synonymous with superior sound quality.

It’s also widely enabled in mobile devices and is now available in flagship 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. In 2009, aptX was introduced to consumer electronics to provide quality wireless audio – and today, 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. The technology is used to deliver high quality audio in over 30,000 radio stations and 20,000 cinemas across the world. 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.ĪptX audio technology has a long history in the pro-audio and broadcast ecosystems. The CSR8675 provides increased digital signal processing (DSP) performance and more capable I/O subsystems and was designed to be a superior vehicle to bring aptX HD to the Bluetooth headset and speaker space.Īs 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. With aptX HD, we are helping device manufacturers to reduce development time and quickly meet demand.”ĪptX HD is immediately available as part of the CSR8675 Bluetooth audio SoC platform which supports 24 bit audio end-to-end.
“Today consumers enjoy the benefits and freedom of wireless audio on the wide variety of aptX enabled devices available but demand for higher resolution audio is growing to fulfill the desire for the most premium listening experience possible. “aptX transformed the Bluetooth stereo audio ecosystem, providing near CD-quality audio without the need for wires, and consumers now seek out the quality the aptX brand has come to represent,” says Anthony Murray, senior vice president and general manager, IoE, Qualcomm Technologies International, Ltd. According to Qualcomm, aptX HD is designed to enable audio manufacturers to meet the increasing demand for high resolution wireless audio. The new codec basically leverages the existing aptX audio codec platform - which already supported 24 bit resolution in previous implementations for the broadcast contribution market, for instance - now adapted to transmit higher quality stereo audio over Bluetooth. All of CSR’s engineering, research and development functions and all of the CSR products and services businesses are now integrated in Qualcomm Technologies International, Ltd., a subsidiary of Qualcomm Technologies.ĭuring the CES 2016 show in Las Vegas, Qualcomm announced that its subsidiary is now launching the new Qualcomm aptX HD enhanced codec as another option in its family of aptX codecs, allowing the support of 24 bit audio over Bluetooth. Qualcomm acquired Cambridge Silicon Radio (CSR) in 2015 and, at CES 2016, already introduced all CSR solutions and technologies as part of its renewed offerings.
