    STM32F7 Discovery - Play Audio WAV & MP3 with playback and change tempo

    Hello,

    I registered on this forum to find help.
    I have a development board, the STM32F7 Discovery.
    It has a lot of functionality for audio playback.

    I can play Wave and MP3 files from a USB stick and an SD card.
    Now I would like to be able to change the speed (tempo) and play the music backwards (reverse play).
    Despite searching the internet, I can't find these functions for my STM32F7.

    If anyone has an idea or the beginning of a source code, I would be very grateful.

    Thank you for your help.

    Best regards.

    You will not find help here, too. This forum is about Teensy boards.
    Closing here.
