LDAC (codec)
Developed by Sony
Type of format Audio codec

LDAC is an audio coding technology developed by Sony, which allows streaming audio over Bluetooth connections up to 990 kbit/s at 24 bit/96 kHz (also called high-resolution audio). It is used by various Sony products, including headphones, smartphones, portable media players, active speakers and home theaters. LDAC is a lossy codec[1][2], which employs a hybrid coding scheme based on the MDCT[3] to provide more efficient data compression. Its main competitor is Qualcomm's aptX-HD technology. While not directly competitive in terms of bitrate, AAC is used by Apple for its flagship mobile phones and is supported on its Mac-branded personal computers.[4]

Starting from Android 8.0 "Oreo", LDAC is part of the Android Open Source Project, enabling every OEM to integrate this standard into their own Android devices freely.[5]
