Setting BLUETOOTH audio codecs (Bluetooth Codec - AAC/Bluetooth Codec - LDAC)
You can enable and disable AAC (Advanced Audio Coding) or LDAC audio.
Select [Setup] - [Bluetooth Settings] from the home menu.
Select [Bluetooth Codec - AAC] or [Bluetooth Codec - LDAC].
Select the setting you want.
- On: AAC and/or LDAC audio is available if the BLUETOOTH device supports AAC or LDAC.
- Off: AAC and/or LDAC audio is not available.
- When you change these settings, the settings are applied from the next time you connect the BLUETOOTH device.
- These functions work only when the [Bluetooth Mode] is set to [Receiver] or [Transmitter].
- While a BLUETOOTH device is connected, the settings of these functions cannot be changed.
- You can enjoy high-quality sound if AAC or LDAC is enabled.
- 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 (*1), and allows approximately three times more data (*2) than those other technologies to be transmitted over a BLUETOOTH wireless network with unprecedented sound quality, by means of efficient coding and optimized packetization.
