Question about the sound examples and serach method

[sailor88128]

Hi Julio,
Just run your demo, it seems exact. I have two small questions here.

1. As you used the coordinate such like [7, 20, 2], such a large-aperture microphone array. Is the algorithm related to the aperture? In addition, I wonder if the sound example you recorded or just simulated?
2. The grid search methond you used is just grid by grid right? I cannot find code about Stochastic Region Contraction.
   Thanks in advance.
