Sub band codec

Mar 22, 2023 · aptX HD is not a codec by itself but a tweak of the original aptX codec. It offers a much higher data rate, and more bits are assigned for frequency band encoding, resulting in a higher transfer rate. The sonic quality is noticeably better for the average user, but it results in a much higher latency than aptX LL and even than the original aptX.
