Low Latency High-Definition Audio Codec (LHDC) is an audio codec technology developed by Savitech. LHDC allows high-resolution audio streaming over Bluetooth. It is a high-quality Bluetooth codec based on the A2DP Bluetooth protocol and allows a bit-rate of up to 900 kbit/s compared to SBC's bit rate of 345 kbit/s .[1]

LHDC is an alternative to Bluetooth SIG's SBC and LC3 codecs. Its main competitors are Qualcomm's aptX-HD/aptX Adaptive, Huawei 's L2HC and Sony's LDAC codec.

Starting from Android 10, enumeration constant symbols for LHDC and LLAC are part of the Android Open Source Project, enabling every OEM to integrate this standard into their own Android devices freely.[2][3] Older versions of Android require LHDC/LLAC enumeration constant symbols to be implemented by the smartphone manufacturers or Android app. Android apps with this type of LHDC support include Savitech's Hi-Res BT Player, FiiO Music, HIFIMAN Music and DA&T Audio.
