Tuning Parameters values for Respeaker Mic Array v2.0

I want to use the respeaker in a classroom environment. As there are many tuning parameters (<LINK_TEXT text=“https://github.com/respeaker/usb_4_mic_ … /tuning.py”>https://github.com/respeaker/usb_4_mic_array/blob/master/tuning.py</LINK_TEXT>), I want to understand how the behaviour will change when these values are changed. For example, consider AGCTIME. I can understand that it is probably the time in which the AGC processes the change in input signals and changes the gain. What should be the value? I can, of course, change all these values and try practically, but there are too many parameters. I want a theoretical description of each parameter.
