New aptX Bluetooth audio codec dynamically adapts for optimum performance
The new version of the aptX codec, says the company, combines enhancements in robustness, premium audio quality, scalability, low-latency, and low-bit-rate audio transmission to support “a superb wireless listening user experience” for demanding applications like mobile gaming, watching video, and music listening. The aptX Adaptive technology automatically adjusts 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.
“aptX Adaptive is advancing our industry as it is designed to deliver audio quality that matches wired performance across a wide range of sources and to provide consumers with the immersive wireless listening experience they are looking for,” says Anthony Murray, senior vice president and general manager, voice & music, Qualcomm Technologies. “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.”
Optimized audio for a phone call is very different than for music, says the company, or for applications where latency is critical such as gaming. A massive uptake in mobile gaming and mobile video consumption means that wireless audio devices need to deliver fully synchronized audio and video content. According to the company’s research, 30% of consumers surveyed said they want to use their wireless headphones for gaming or to watch video content, in addition to listening to music and making calls.
“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,” says Jonny McClintock, director, product marketing, Qualcomm Technologies. “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,” says McClintock, “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.
