| Standard | Bluetooth 5.2 LE |
LC3 (Low Complexity Communication Codec) is an audio codec specified by the Bluetooth Special Interest Group (SIG) for the LE Audio audio protocol introduced in Bluetooth 5.2.[1] It's developed by Fraunhofer IIS and Ericsson as the successor of the SBC codec.[2]
It provides higher audio quality and better PLC than SBC, G.722 and Opus according to subjective testing by the Bluetooth Special Interest Group and ETSI.[3][4] [5] Notably, the test only included comparison to Opus 1.1.4 complex level 0 at 32kbps, it did not use the newer Opus 1.2 released in 2017 where significant improvements were made to low bitrate streams or include any higher bitrate.
