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. It's developed by Fraunhofer IIS and Ericsson as the successor of the SBC codec. Supported systems: * Android 13 * Zephyr OS

Property Value
dbo:abstract
  • 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. It's developed by Fraunhofer IIS and Ericsson as the successor of the SBC codec. LC3 provides higher audio quality and better Packet loss concealment than SBC, G.722 and Opus, according to subjective testing by the Bluetooth Special Interest Group and ETSI. The conclusion regarding Opus is disputed as the test only included speech audio, but the comparison was made to version 1.1.4 of the reference Opus encoder, using complexity level 0 at 32kbps and relying on CELT (general audio) instead of 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. Supported systems: * Android 13 * Zephyr OS (en)

  • LC3 (Low Complexity Communication Codec)は、フラウンフォーファー IIS（集積回路研究所）とエリクソンが中心となって開発した音声圧縮コーデックである。Bluetooth 5.2で導入された LE Audioのコーデックとして採用され、SBCに対して同じビットレートではより低遅延・高品質・低消費電力となっており、半分のビットレートで同程度の品質を実現できると言われている。 (ja)
