  • 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-CCA02M1 expansion boards and the STEVAL-MKI129Vx digital microphone evaluation board series or the BlueCoin starter kit (STEVAL-BCNKT01V1).

    主要特性

    • AcousticBF real-time beam forming software expansion for STM32Cube
    • AcousticEC real-time acoustic echo cancellation software expansion for STM32Cube
    • AcousticSL real-time sound source localization software expansion for STM32Cube
    • Complete application including all the acoustic functions in a single sample application
    • Software graphic user interface to easily control parameters and algorithms from a host PC
    • Free, user-friendly license terms
    • Sample implementation available on a NUCLEO-F446RE board when connected to an X-NUCLEO-CCA01M1 and an X-NUCLEO-CCA02M1 expansion board
    • Sample implementation available on the BlueCoin starter kit (STEVAL-BCNKT01V1)
