  • 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-MIC001Vx, STEVAL-MIC002Vx or STEVAL-MIC003Vx digital microphone evaluation boards or the BlueCoin starter kit (STEVAL-BCNKT01V1).

    主な特徴

    • Software expansions for STM32Cube:
      • AcousticBF real-time beam forming
      • AcousticEC real-time acoustic echo cancellation
      • AcousticSL real-time sound source localization
    • 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 development board when connected to an X-NUCLEO-CCA01M1 and an X-NUCLEO-CCA02M2 expansion board
    • Sample implementation available on the BlueCoin starter kit (STEVAL-BCNKT01V1)
