Hi,

Default value of LC3 bitrate is 96 Kbps, default audio sample rate is 48 KHz and bit depth is 16.

Best regards,

Hi,

Thanks for your reply. I would also like to check the available sample rate and bit depth of PCM after LC3 decoding?

Best Regards

Hi,

Available UARTs can be found by looking at nRF5340 audio DK dts files located in \nrf\boards\arm\nrf5340_audio_dk_nrf5340.

You could for example use P1.12, P1.13 or P1.14. You can find more information by looking at nRF5340 Audio DK hardware files.

Regarding the example, we have only sample which shows how to receive audio data via USB or I2S from external sources. It can be found in nRF5340 Audio DK documentation.

Best regards,
Dejan
