I suspect that mobile phones use NTP which could be quite a number of milliseconds out.
However, it depends what exactly you really mean with the question? It could mean many things.
Note, for gunshot localization I think someone has already built an app that I think they are trying to sell to the authorities.
Maybe I can answer better if you clarify which part you are asking could be done on a phone ?
Certainly the localization math can be.
- hcfman 3y agoThe localization calculations you can do on an Android, recording audio aligned to less than a millisecond of error I’m pretty sure you cannot.
- xchip 3y agowell, you can use some sort of radio signal so sync a beep and use that for syncing.
- hcfman 3y agoSounds viable. A lot of beeping.
- BHSPitMonkey 3y agoAre you aware of any forums/groups where people network these sorts of setups with people in their area? I live near a tech hub and have been wondering if something like this could be possible to cover a larger area or neighborhood, but I don't know anyone personally who would probably be as interested.
