Microphone module i am using is MP34DT01, and by sai peripheral i got pdm signal from mic.
To use microphone input with edgeimpulse trained keyword-spotting model, i want to convert pdm to pcm, then some more audio processings. I am using nucleo n657x0q board.
I saw pdm2pcm software library, but it doesn't have .a file for the CM55, so i cannot seem to convert pdm to pcm. 
Can anyone help me with the this software library using with NUCLEO-N657X0Q or any guide?
