Final Approach
Ok, so if I wanted to record gunshots, say, 2-3 blocks away and have a real-time livestream of it, what equipment would I need? If three to four neighbors wanted to participate, could we triangulate them?
Nightly semi-auto fire in the middle of a big city??? Multiple 911 calls by multiple parties and nothing can be done because no one wants to talk. And yeah, I've taken a bullet to the hood of my truck already. Came almost straight down, looks like.I’m curious why?
Is it www.shotspotter.com ?Come to Cincinnati; they have such a setup installed already. It's a commercial product.
You also need to check if you can zoom in sufficiently with audacity to measure time differences of small fractions of a millisecond - my guess is you can

I’d suggest putting the microphones as far apart as possible, and of course you’ll want the array oriented broadside to your suspected point of origin. A triangular or rectangular array would be more omnidirectional.
If I were setting something like this up, I’d use Raspberry Pi’s syncing time using either NTP (free, good time sync) or low cost GPS (cheap, great time sync).I just made it up. I was thinking about how to get accurate time sync across sites and all solutions looked too expensive. Suddenly noticed that it might not be necessary.
Agree with as far apart as poss. Sample rate will likely be 44 or 48kHz so need at least a few feet I would think.
Thing is a PC or other cheap recorder is Stereo and so no more channels are available without exotic (expensive) hardware.
Maybe consider moving out of the hood?Nightly semi-auto fire in the middle of a big city??? Multiple 911 calls by multiple parties and nothing can be done because no one wants to talk. And yeah, I've taken a bullet to the hood of my truck already. Came almost straight down, looks like.
Not an option right now.Maybe consider moving out of the hood?
