fitNonLinearModel_explosion.m

See my related demo where there were several microphones places around and we had time of arrivals of the sound of an explosion. With that I was able to pinpoint the location of the explosion.

Once you know the location of the sound origin, you can easily find the direction of arrival from the sound origin to the individual microphones.

I have 6 amplitude of each signal in real-time. I can take FFT The problem here is :how I analyze this parameters(amplitude in real time for each signal or fft) to determine bearing of sound source

If they all hear basically the same sound, but the signal is just shifted in time because the mics are different distances from the source of the sound, then you can use xcorr to determine the delta time. Then I think you can use my demo. That's about all I can suggest since you don't want to attach your data like I suggested (which is fine). So good luck.
