How to calibrate respeaker? What can I do if it points to wrong direction of sound?

[Gaurav37]

Which version is your board?

Note: It might be ReSpeaker (v1) or ReSpeaker Core v2, please see the pictures to know what they look like.
Its V2

I'm using respeaker v2. We calibrate every sensor in robotics.
How can I calibrate respeaker or check if its giving the correct directions?
What can I do if I find out that its giving wrong directions?

Thanks
Gaurav
