Odas cfg is incorrect

[taospartan]

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

@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 = ( # Microphone 2 { mu = ( +0.0239, +0.0239, +0.000 ); sigma2 = ( +0.000, +0.000, +0.000, +0.000, +0.000, +0.000, +0.000, +0.000, +0.000 ); direction = ( +0.000, +0.000, +1.000 ); angle = ( 90.0, 100.0 ); }, # Microphone 3 { mu = ( -0.0239, +0.0239, +0.000 ); sigma2 = ( +0.000, +0.000, +0.000, +0.000, +0.000, +0.000, +0.000, +0.000, +0.000 ); direction = ( +0.000, +0.000, +1.000 ); angle = ( 90.0, 100.0 ); }, # Microphone 4 { mu = ( -0.0239, -0.0239, +0.000 ); sigma2 = ( +0.000, +0.000, +0.000, +0.000, +0.000, +0.000, +0.000, +0.000, +0.000 ); direction = ( +0.000, +0.000, +1.000 ); angle = ( 90.0, 100.0 ); }, # Microphone 5 { mu = ( +0.0239, -0.0239, +0.000 ); sigma2 = ( +0.000, +0.000, +0.000, +0.000, +0.000, +0.000, +0.000, +0.000, +0.000 ); direction = ( +0.000, +0.000, +1.000 ); angle = ( 90.0, 100.0 ); } );

It's just the coordinate rotates 45 degree.

[taospartan]

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.

[taospartan]

Ok
