Qualcomm came up with how to improve the sound in wireless headphones: Thanks to Apple, more and more manufacturers of smartphones on Android are beginning to abandon the 3.5-mm connector. Because of this, users are forced to use adapters or wireless headphones. Qualcomm understands this and decided to make a new version of the audio codec AptX.
The new version of AptX is called Adaptive, and its key feature is the compression of audio with variable bitrate. This means that the codec will choose between high sound quality and low latency, depending on the conditions of use of headphones and the quality of the signal. For example, if you listen to music on the street, then the sound quality will be good, and when you watch the movie, AptX itself synchronizes the audio track with the video.
AptX Adaptive should replace the traditional AptX and the newer AptX HD. The bitrate of the new codec may be lower than the old one (the lowest point in Adaptive is 280 kbps, and the usual one – 384 kbps), but you will not get the quality of the HD-version (420 kbps Adaptive versus 576 kbps in HD). Chris Havell, senior director of marketing for Qualcomm, said that the sound from this will not be worse since the new codec will help achieve the same level of quality with a smaller file size.
It is assumed that AptX Adaptive will be integrated into Android Pie, so all new phones will support it. Havelle suggests that the first earphones with Adaptive support will appear in early 2019 and will be backward compatible with previous versions of AptX.
Apple this update will bypass since no iPhone supports AptX. The same goes for the Beats. However, the “Yabloko” will not be sitting still, and most likely they will come up with their version of an adaptive codec.
