LC3 provides higher audio quality and better packet loss concealment than SBC and G.722, with disputed results against Opus, according to subjective testing done by the Bluetooth SIG and ETSI. The comparison against Opus is disputed for the test including only speech audio, and using the older 1.1.4 version of the reference Opus encoder, at complexity level 0 at 32kbps and relying on CELT (general audio) instead of the FEC-capable SILK (speech); the test also did not take into account the newer version 1.2 of the Opus encoder released in 2017, where significant improvements were made to low bitrate streams.
Intel CPU: Intel 13th gen or newer that support Intel Smart Sound Technology. Intel AX210 network card or newer with capabilities of at least Wi-Fi 6E and Bluetooth 5.3 with latest drivers, if conditions met Intel Smart Sound Technology for Bluetooth LE Audio driver will be installed.
LC3plus is defined by ETSI and is not royalty free nor compatible with the standard LC3 codec.:3 It's included in the 2019 DECT standard, and reference encoder/decoder is source-available, Google's liblc3 encoder/decoder library has support to it, but doens't cover necessary patents rights about it. The codec received Hi-Res certification from the Japan Audio Society (JAS) in 2022, alongside the SCL6, LDAC and LHDC.
