Bluetooth SBC Encoder and Decoder

The low complexity, subband codec (SBC) is described in the Advanced Audio Distribution Profile (A2DP) specification produced by the Bluetooth Special Interest Group. SBC was designed to obtain high quality audio at medium bit-rates whilst having low computational complexity. The SBC audio codec can be used to connect high quality Bluetooth audio devices.

ESPICO’s highly optimised implementations have low memory and MHz requirements. Contact ESPICO for specific resource requirements.
