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*, and 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.
*
Excluding DSD format contents.
** In comparison with SBC (Subband
Coding) when the bitrate of 990 kbps
(96/48 kHz) or 909 kbps (88.2/44.1 kHz)
is selected.
x [Wireless Playback Quality]
This function is enabled when
[Bluetooth Mode] and [Bluetooth Codec
- LDAC] is set to [On]. If sound output
or network streaming is unstable, please
select [Connection].
[Auto]: Sets the transmission data rate
for LDAC automatically.
[Sound Quality]: The highest data rate is
used. Sound is sent at a higher quality,
but audio playback may become
unstable if the link quality is not
sufficient.
[Standard]: A medium data rate is used.
This provides a balance between sound
quality and playback stability.
[Connection]: Stability is prioritized.
The sound quality may be reasonable
and the connection status will most
likely be stable.
