I’m working on a project to make a sound source locator. My theory is to detect the sound using two microphone located at a known distance and find out the time delay to make out the direction of the sound. I am using matlab to take input from the microphone. To take input from two microphones, I used two laptops. I need the recording to start automatically, so I used Internet time synchronisation in both the laptops and then wrote a code in matlab to start the recording at a specified time. But the problem is that, the internet time synch is not accurate enough. I need something like millisecond precision. That’s not happening with internet time synch. Any solutions to any part of the problem?
