Super Inaccurate DOA. #28

Hi, I have a Respeaker Mic Array V2, and I am using it under ubuntu. The DOA is terrible on mine just by observing the tracking LED light that rotates and tries to indicate the DOA of the sound. Is there a calibration procedure that would improve it? Thank you in advance.

It turned out to be the old plastic enclosure that we were using. The enclosure was creating some acoustic noise. After taking out of the enclosure, the DOA is much more accurate. The new plastic enclosure provided by seeedstudio is much better, and has solved the problem.
