WAV/MP3 player with STM32746G-Discovery.

Hello, I downloaded STM32CubeExpansion_Audio_V1.1.1 and I tested the MP3 player project (Audio_MP3_player) with an STM32746G-Discovery.

It works very well.

But now, I would like to add 2 or 3 additional functions but I have big gaps in development.

I would like to add a speed or pitch function (+/- 10%) and a reverse play function.

When playing a WAV or MP3 file, the audio file is buffered before being played.

I think it's in the fwkmempool.c file or player.c file to add these functions but I can't seem to.

If anyone can help me it would be welcome.

Thanks for your help.

Regards.

Nobody ?

It's a forum, most people are occupied with their own projects and problems.

Update: I found out how to play an MP3/Wave sound while changing the playback speed.

Now I have to figure out how to play an MP3/Wave sound backwards.

Here is the link to download my project written with keil for the STM32F7.

In the meantime I have managed to get the music speed to work at +/- 100%.
