Hello @AGupt.17​ 

You can refer to the following example which uses  PDM to PCM conversion in the waverecorder part:

• Projects\STM32F411E-Discovery\Applications\Audio\Audio_playback_and_record

The pdm2pcm lib is provided under this path: Middlewares\ST\STM32_Audio\Addons\PDM

I hope this helps.

BeST Regards,

Hi Walid,

I understand that this is a moving target. Sadly.

https://github.com/STMicroelectronics/STM32CubeF4/tree/master/Middlewares/ST/STM32_Audio/Addons/PDM currently is empty, contains only readme.txt which tells us to go to https://www.st.com/en/licensed-software/audiopdm-mw.html?softwareProduct=AudioPDM-MW&softwareVersion=3.2.0 and that in turn just throws a generic 404.

Shouldn't there be a web folder for the PDM-PCM library, to which UM2372 belongs?
