This addition to Qualcomm's premium audio portfolio combines enhancements in robustness, premium audio quality, scalability, low-latency and low-bit rate audio transmission to support an improved wireless listening user experience for today's most popular and demanding applications including mobile gaming, watching video and music listening. According to Qualcomm, the new aptX Adaptive technology was engineered to automatically adjust to provide optimum audio quality or latency depending on the type of content being played on the device while also taking into account the external RF environment to support a robust connection.
The codec recognizes the type of content that is being played back and, depending on the content, delivers audio using low-latency aptX, aptX, or aptX HD, combining the features of all of these solutions. The technology is backwards compatible with aptX and aptX HD enabled devices, supports compression ratios from 5:1 to 10:1 and supports 24-bit audio at 48 kHz with 276kbit/s and 420kbit/s with bit-error resilience. According to Qualcomm the new audio codec also supports legacy Qualcomm TrueWireless Stereo and dual-mono Qualcomm TrueWireless Stereo modes.
“With this new product, listeners don’t have to do anything while aptX Adaptive dynamically adjusts performance to best deliver exceptional audio whether the user is playing games or listening a song,” says Anthony Murray, senior vice president and general manager, voice & music, Qualcomm Technologies International, Ltd.
“Most audio codecs available today are largely static in nature with fixed bit-rates which can lead to wireless connectivity issues in challenging RF environments,” adds Jonny McClintock, director, product marketing, Qualcomm Technologies International, Ltd. “Many of these codecs were designed for music listening and are simply not suitable for low-latency gaming and audio/video applications. aptX was one of the first technologies to really help make a difference to the Bluetooth music listening experience and we’ve continued working hard to create a technology that will help transform the listening experience for the next generation of consumers who want to replace the wire completely.”
The aptX Adaptive decoder, for devices such as headsets, headphones and speakers, is scheduled to be available on the Qualcomm CSRA68100 and the Qualcomm QCC5100 series Bluetooth Audio SoCs from September 2018. A version of the aptX Adaptive encoder for devices such as smartphones and tablets is scheduled to be available to run on Android P from December 2018.
