— one of the varieties of the aptX codec (see the relevant paragraph), designed not so much to improve sound quality, but to reduce delays in signal transmission. Such delays inevitably occur when working via Bluetooth; they are not critical for listening to music, however, when watching a video or playing games, there may be a noticeable out of sync between the image and sound. The aptX LL codec eliminates this phenomenon by reducing the latency to imperceptible to human hearing.
