2 PDM microphones data from SPI using PDM to PCM library?

[Viki]

Hello!

I want to interface 4 PDM microphones with STM32F401RE's SPIs in stereo config(like in the pic above), I have a problem of how to get its data using pdm to pcm library. As the data will be alligned in this form(M1bit1, M2bit1, M1bit2, M2bit2..........M1bitn, M2bitn).

Can someone give me a piece of code or some kind of explanation on how to get the data?
