    Hi @Community member​ ,

    please note that the 4 MEMS microphones on STM32F769I Discovery Board are digital microphones (precisely MP34DT01-M) and use DFSDM inputs.

    If you want to use an analog microphone, you should use (for example) a MP23ABS1 and connect its output (better if AC couples) to an available ADC input of the STM32F7 microcontroller on STM32F769I Discovery (you may check the STM32CubeMX predefined code for this board, if you want to start almost from scratch).
