* 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*
allows approximately three times more data*
than those other technologies to be transmitted
over a BLUETOOTH wireless network with
unprecedented sound quality, by means of
efficient coding and optimized packetization.
