6-Mic Array Channel Mismatch

Hi everyone,

I am using 6-mic array for my project. During my experiments, I find that the indexes of collected data array and the indexes of the mics are not fixed nor matched. It seems there is a different channel shift every time I restart recording.

Without knowing which mic corresponds to which collected data, my project is completely stuck. Please, is there a way to solve it?

Thank you very much!
