https://devzone.nordicsemi.com/f/nordic-q-a/124648/linux-lc3-pre-encoded-audio-over-usbWe want to encode audio to LC3 format before we pass it to nrf5340 over USB. Because we know the processing power of nrf5340 is limited. Do you have any support for this?

We recommend trying to compile and run it on a PC to evaluate its functionality in your environment.</p> <p>Hope this helps!<br /><br />Kind regards,<br />Øyvind</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/550116?ContentTypeID=1Tue, 30 Sep 2025 09:20:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:29242ee1-7d5f-4542-9b4e-c8239a74fc72&#216;yvind<p>Hello, sorry for the delayed answer. I have forwarded your question to our team to get a definite answer, but I assume the answer is no in regards to real-time encoding.</p> <p>But I will update you as soon as I have an answer.&nbsp;<br /><br />Kind regards,<br />Øyvind</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/549922?ContentTypeID=1Fri, 26 Sep 2025 20:48:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9446d5b3-311c-47aa-a4ae-7d8ae01a59d8Teppo<p>And to be more precise, encoding must be real-time. We can&#39;t encode first to file and then transfer it. So essentially we want Linux driver, like snd-usb-audio, to which we can play audio to in LC3 format.</p><div style="clear:both;"></div>
