Audio Technology and LRAD
« on: December 02, 2020, 12:37:42 PM »
I am posting this because this really gets into the technology and physics of sound .
The Classic seems to have had an effective warbler sound in one of the voice or alarm features - though I turned it all off it made me jump when I first turned on the talking stuff and it would randomly go off - ha ha.
The funny thing is I recently saw a Seattle demonstration live stream and someone saw a cop car with a big box on top and said it might be LRAD and I didn't even know what that was . Now I do.

Yeah, we should be selling MNGPs to the Seattle Police Department soon with that bug in them to help keep the rioting down
