LDAC

A codec from Sony that supports high-resolution audio via Bluetooth. LDAC transmits up to 990 Kbps rather than 328 Kbps, which is the highest rate required by the SBC codec in the Advanced Audio Distribution Profile (A2DP), the standard for sending stereo via Bluetooth. See Bluetooth audio, linear PCM and high-resolution audio.
