noise cameras
We call those "microphones" where I'm from :-P
This sounds like a good idea. I wish we had something like that where I live. I shouldn't be able to be woken up in the middle of the night by a vehicle half a mile away. There's no good reason for a vehicle to make that level of noise.
I wonder if Nintendo is considering training an AI voice model based on Martinet's recordings or something. Are they advanced enough yet to do convincing wahoos? I can't imagine another voice for Mario.
