Hi,

I'm trying to implement some audio processing functions for my mp3 player project based on processing libraries provided by ST, but I have some problems getting that to work. The UM1798 

Audio engine post-processing on STM32F4xx

Graphical Equalizer library

has mentioned something about an example application that comes with the STM32 audio framework. I was wondering where I can get that application so I can see how the processing was done and apply that to my project.

Thanks

But where I can get the Spirit MP3 Decoder? Is it the same MP3 decoding library for STM32 devices that is surrounded with mystery? I wouldn't have bothered with Helix if I had this lib from the beginning. The API for the modules and Add-ONs seems very versatile and promising, unlike that of the Helix. But, again, where I can get it?
