Audio - why is there no information here at all?

What audio chip is included on this board?

Why are there no audio examples?

Question relating to:

The 32F413HDISCOVERY Discovery kit allows users to develop applications with the STM32F4 Series microcontrollers based on ARM® Cortex®-M4 core.

Hi Ralph, did you find a good audio example ?

Hi I agree that I couldn't find any audio examples...

Maybe you can start to check F413 BSP files : https://os.mbed.com/teams/ST/code/BSP_DISCO_F413ZH/

And in particular the audio file: https://os.mbed.com/teams/ST/code/BSP_DISCO_F413ZH/file/0f07a9ac06f7/Drivers/BSP/STM32F413H-Discovery/stm32f413h_discovery_audio.c/

That seems to concentrate on playback existing audio. I'm more interested in signal processing, and would like to see a very simple example which captures audio from the input device, and routes it to the output device. I can then put my own signal processing into the loop.
