I want to create a sound detector that detects when sound comes from a place a few inches from it. I've seen some Arduino hobby projects that accomplish sound localization through volume differences of microphones, but I don't know how well this method works. It seems like a sound could come from somewhere else and it could have the same volume difference, I'm not sure...I'm thinking of the method of using the phase difference output from microphones. I've found Phase Comparator chips online...do you think a phase comparator could be used for this application?
