How does all of this translate into sound-per-pound performance? It translates very well indeed actually.
To put those figures into perspective, SBC (the standard 'vanilla' Bluetooth codec) achieves a maximum data rate of just 328kbps, while Qualcomm's aptX HD can only stream at 576kbps. According to Sony, it also permits around three times the amount of data to be streamed over Bluetooth thanks to the use of more efficient coding and “optimised packetization” of the data. Why so? LDAC allows you to stream better-than-CD high-resolution audio up to 32-bit/96kHz over Bluetooth at up to 990kbps. The top-draw name on the spec-sheet is undoubtedly LDAC support, Sony's proprietary 'hi-res' codec.
