@taospartan Can you explain what is wrong?
If you look at the microphone coordinates they are spaced incorrectly, looks like the mics are positioned in a straight line
Many thanks

They are not in a straight line.

My mistake, but they are still not plotting sound sources correctly, this is my config for the mics see what you think
mics = (

It's just the coordinate rotates 45 degree.
I understand but unless you do rotate your coords 45 degrees odas does not work as intended especially the tracking . Feel free to test your self

I tried your configuration, but didn't see much difference. Maybe it is the difference between angle = ( 90.0, 100.0 );
and angle = ( 80.0, 100.0 );
. Otherwise, it should be a bug.
Ok

The microphone layout for use in odas is totally wrong. Results in false doa and separation.
