Hello,

In the FP-AUD-BVLINKWB1 – FullBand example, the microphone it’s not used, so you can use the SAI to connect an external audio codec (you can see an example available for other STM32 family here: https://www.st.com/en/embedded-software/x-cube-soundter1.html).

Anyway if you just need to record the received stereo music @48kHz, you can use the FullBand FW as is, connect the board to the PC via USB and record the audio for example using Audacity, you can find more information in the User Manuel of the FP-AUD-BVLINKWB1.

Best Regards
