LDAC is an audio coding technology developed by Sony, which allows streaming high-resolution audio over Bluetooth connections at up to 990 kbps at 24 bit/96 kHz. It is used by various Sony products, including headphones, smartphones, portable media players, active speakers and home theaters. Its main competitor is Qualcomm's aptX-HD and the HWA Union/Savitech's LHDC.
|Type of format||Audio codec|
LDAC is a lossy codec, which employs a hybrid coding scheme based on the Modified discrete cosine transform to provide more efficient data compression. LDAC can switch between 330/660/990 kbps depending on connection strength.
The encoder library is open source and the implementation for Linux is already present in bluez-alsa and pulseaudio-modules-bt. It is available on Fedora with RPM Fusion since Fedora 30.
On 17 September 2019, the Japan Audio Society (JAS) certified LDAC with their Hi-Res Audio Wireless certification. Currently the only codecs with the Hi-Res Audio Wireless certification are LDAC and LHDC.
