DOA estimation real time

I'm working on a project that requires me to identify the position of a source sending sound signals from 4 sound sensors.

If anyone can please help me with it, as from to start and what tools to be used I would really appreciate it.

Note that I got the signals to be sampled an converted then sent to Matlab, so meaning that signals are ready to be processed.

Thanks in advance.

A similar problem has been addressed here. The example provided would need few modifications to accommodate sound waves, instead of electromagnetic waves. It would be a good starting point for the problem at hand.

Hope it helps!

Thanks Pappu, but unfortunately the distance between my sensors in the array is too small, making it as narrowband and relying on the phase difference. Is there any other way you suggest for this type of DOA?

Thanks in advance
