Simulated room mixtures:

1.      Used Image method to simulate room mixing

2.      Distance between the two microphones in each array was 4 cm

Notes:

1-Circle represents the true trajectory and triangle represents the estimated trajectory

2-The sources turn Green when active and White when silent.
