STMicroelectronics' FP-AUD-SMARTMIC1 is an STM32Cube function pack. This software package implements a complete application targeting advanced processing for MEMS microphone arrays including digital MEMS microphone acquisition, beamforming, source localization, and acoustic echo cancellation. The processed audio is sent to a USB host and a loudspeaker connected to the relevant expansion boards.
The function pack is built on STM32Cube software technology to ease portability across different STM32 microcontrollers.
This sample implementation supports two kinds of systems: STM32 NUCLEO-F446RE development board equipped with the X-NUCLEO-CCA01M1 or X-NUCLEO-CCA02M1 expansion boards, and the STEVAL-MKI129Vx digital microphone evaluation board series or the BlueCoin starter kit (STEVAL-BCNKT01V1).
