LDAC is an audio coding technology developed 
by Sony that enables the transmission of High-
Resolution (Hi-Res) Audio content, even over a 
BLUETOOTH connection. Unlike other 
BLUETOOTH compatible coding technologies 
such as SBC, it operates without any down-
conversion of the Hi-Res Audio content*

7

, and 

allows approximately three times more data*

8

than those other technologies to be transmitted 
over a BLUETOOTH wireless network with 
unprecedented sound quality, by means of 
efficient coding and optimized packetization.
