https://devzone.nordicsemi.com/f/nordic-q-a/119012/nrfxlib-lc3-library-for-cortex-m4Hi, We&#39;re developing a device based on the nrf52840. We want to read LC3-encoded files on the filesystem, decode them, then send the data to the i2s peripheral. However, we realised that libLC3.a is only available for cortex-m33, which is theen-USTelligent Community 13Mon, 17 Feb 2025 11:51:52 GMThttps://devzone.nordicsemi.com/thread/523237?ContentTypeID=1Mon, 17 Feb 2025 11:51:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:177fb16b-d0c0-4604-9265-b3ae2d65a118Maria Gilje<p>Hello, </p> <p>The <a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/lc3/README.html">nrfxlib implementation</a> of the LC3 codec is only for the ARM Cortex-M33, but there is another implementation available in Zephyr: <a href="https://github.com/zephyrproject-rtos/liblc3/tree/main">https://github.com/zephyrproject-rtos/liblc3/tree/main</a>. I suggest to use the latter in your project.</p> <p>Best regards,</p> <p>Maria</p><div style="clear:both;"></div>
