Gottfried,
thank you for your post. I understand the problem caused by the STM32. And like Hans wrote before the analogue channel for the internal mic is used for the reference signal.

At first, after the information from Hans, I was thinking the same. But I guess the noise I was talking about is not received via this mic from the air.
