Woah what?? I didn’t know that a laser could be used like that

[@CameronL211]

You probably have a device like a computer that can do this, on the back of most pc’s is a optical audio port, this uses lasers to send optical audio to speakers through a glass wire, but they are easily breakable. It’s the same technology as this

[@sundhaug92]

There's even a variant of this used for espionage by bouncing off a membrane and measuring time of flight (and/or frequency) to detect sound

[@deaconmile]

There a repo or docs for it!?!? 😮

Is this like when they were starting to listen to mafia conversations through glass and a laser?
