Product overview
Description
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 kind of systems: STM32 NUCLEO-F446RE development board equipped with the X-NUCLEO-CCA01M1 or X-NUCLEO-CCA02M2 expansion boards and the STEVAL-MIC001V1, STEVAL-MIC002V1, STEVAL-MIC003V1 or STEVAL-MIC005V1 digital microphone evaluation boards or the BlueCoin starter kit (STEVAL-BCNKT01V1).
The software is available also on GitHub, where the users can signal bugs and propose new ideas through Issues and Pull Requests tabs.
