— an improved and refined version of aptX technology (see the relevant paragraph), which allows you to achieve even higher sound quality. If the original aptX provides signal transmission with 16-bit/44.1kHz characteristics (Audio CD), then aptX HD already works with 24-bit/48kHz, which complies with Hi-Res standards. The creators claim that such a connection in terms of sound quality is not inferior to a wired one; one can argue with this, however, in general, aptX HD is still noticeably superior to aptX, and even more so to conventional Bluetooth (although inferior to LDAC). At the same time, it should be taken into account that all the advantages of this technology become noticeable only on Hi-Res audio — with a quality of 24-bit/48kHz or higher; otherwise, the quality is limited not so much by the characteristics of the connection as by the properties of the source files.
