Audio data of each microphone

Hey there,

I’m doing research for an upcoming project and came up with the following question:

I want to use the Microphone Array Matrix Creator with a Raspberry Pi 4B for data acquisition.
Therefore I need to be able to store the data from each microphone. That means I need a separate raw audio file from each of the 8 microphones.
Is this possible? If so, is there a tutorial or link explaining how to do this?

Thanks a lot in advance,
