Bluetooth wireless headsets for gaming? Until now, the excessive latency of the wireless connection was preventing it. This will change with Qualcomm’s AptX Adaptive Evolution.
Using Bluetooth wireless headsets for video or games is complicated by the latency of the wireless link which tends to desynchronize the sound and the image.
Advances have been made in this direction, but it was still necessary to bring together the different components of technology to ensure an optimal user experience.
Qualcomm has been working for several years to improve the AptX technology inherited from its acquisition of the British CSR and AptX HD to offer a sound quality similar to that of a high-quality wired headset, followed by AptX Low Latency to provide lower latency.
The last step of this work is AptX Adaptive, a new codec presented at IFA 2018 that offers the best quality and a low latency (about 40 milliseconds) for a flawless gaming experience.
This is made possible by a dynamic management of the stream (more or less quality, more or less latency) which is adapted automatically according to the diffused content (music, video, game …), when the majority of the audio codecs have a fixed type of operation well suited to listening to music but less effective in other scenarios.
The AptX Adaptive codec also offers a Bluetooth pairing simplicity and a good robustness of the wireless link.
The idea here is to offer a quality and performance close to those of wired audio connections and follow the trend since more and more manufacturers are removing the audio jack from their phones.
Qualcomm says the new codec will debut on an upcoming Snapdragon chipset which may be the Snapdragon 855 chipset that will power next year’s flagships.
