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

[bdomi40]

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.
