The documentation for the LC3 library is found <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/lc3/README.html">here</a>.</p> <p><strong>2)</strong> The library source code for the latest NCS version is <a href="https://github.com/nrfconnect/sdk-nrfxlib/tree/main/lc3">here</a>.</p> <p>Also see the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/nrf5340_audio/README.html">nRF5340 Audio application</a> which demonstrates several LE Audio features depending on the configuration of the application.</p> <p>Best regards,</p> <p>Maria</p><div style="clear:both;"></div>
