That is insane. Never will I feel comfortable having a private conversation in a public area. Hah.
This is some shit spies would use
Dear fucking god the recovered sound from the end of the video is like something straight out of Silent Hill.
Jesus christ it's like the real life equivalent of that one scene in Eagle Eye where [sp]the AI uses the vibrations in the coffee cup to figure out what they were saying[/sp].
This is some creepy shit
This is why people are paranoid. Holy shit the fact that this is possible is insane.
Calling that this will be the new CSI data-recovery gimmick.
"give me a sec guys just gonna extract the sound from this 12fps blurry security cam footage"
I once came across a "fight the system" "how to disappear from anyone" type of document on the net, and one of the things it claimed was that the FBI was able to bounce lasers off of window panes and measure the distortions of the pane of glass vibrating from the sound inside the room, which they could then process to recreate the original sound.
That was actually one of the most believable parts, and the thing was written probably 10-15 years ago. The difference between that and this is the amount of specialized equipment required.
I wonder if something like this is already in use by some sort of agency.
That is impressive as fuck. Imagine when they figure out how to produce crystal clear sound just using the visual vibrations.

well if it by some chance isn't already then it will be now

To me the lasers seem more feasible as a spy device, you can build it specially to hit high frequencies and lasers are already used for rangefinding etc. so I find it very plausible that someone could make that if they really tried.
Not saying that it actually exists or is used to spy but that seems pretty legit to me.
shove a vibrator in youir butt to combat this
win/win

Zoom and enhance
zoom onto that reflection
withdraw the audio from vibrations of the the reflected cup of tee visible on that car window three blocks further

Laser mics are not only common but are pretty easy and cheap to make and have shockingly high sound quality for the distances you can listen from, as long as there's a pane of glass near the people you want to listen to.

whenever i see really cool technological advances like this i sort of get interested in the claims people have made on the subject that were deemed delusional.
like i'm not a conspiracy theorist, but it's well known that a lot of them suffer from mental illnesses. when they make claims like "the government is keeping records of my phone calls and internet habits" that, at first, appear to be completely delusional and not rooted in reality, they're never taken seriously. then the snowden thing happens and it turns out that the government (NSA, Prism, etc) really [I]is[/I] doing those things. is the person still delusional?
if a person 5-10 years ago had made the claim that the government has the technology to pick up audio by focusing a camera or laser on an object or window near someone to pickup what they're saying from far away without a microphone, they'd have been labeled delusional and crazy. but now we know that it really can be done, and it might not even be [I]too[/I] complex. sort of makes me think the definition of "delusion" needs to be touched up.
The definition of "Delusion" doesn't need to be changed. People won't believe things until they have them proven to their satisfaction, and some people are very easy to convince (people likely to be dumb conspiracy theorists) while others are very difficult (skeptics, idiots who believe themselves "skeptics").
It's been known since 2005 or 2006 that the NSA had a secret room in AT&T's San Francisco office that had a lot of equipment in it. It was presumed to be wiretapping, but for phones. We now know that it was probably also for fiber taps for data and for what would later become PRISM. The early AT&T revelation was by a whistleblower who could, of course, not provide much proof of what the NSA was doing, because he didn't have it. And the fact that it was there at all was disregarded by the post-9/11 population.
It becomes easy to disregard uncomfortable thoughts and suspicions by declaring them the product of unemployed tinfoil hatters with mental problems, restoring your reality back to its original wholesome state, untarnished by whatever bad thing the whackjob over here is trying to convince you of.
Then Snowden drops concrete proof that the US government is effectively slurping everyone's browsing history and phone metadata [I]en masse[/I], and only the far end of the spectrum are able to construct a denial bubble strong enough to withstand weeks of document bombs.
People can rationalize and ignore all sorts of things to get themselves through the day. Everyone in the West generally went along on their happy lives while Darfur was happening, right? Same with the Arab Spring wars, the Ukrainian uprising, what is happening in Israel and Palestine right now (NO do not derail the thread, keep that in SH), all the various ongoing conflicts in Africa, etc.
Bags of chips confirmed suitable spy equipment
that's really friggin cool, but what interested me just as much is how the phone recognized the song even with all that static. how does that work?
It's also possible to "see" what's on a computer screen by watching the wall it faces, and some information about the screen.
[QUOTE=Tmaxx;45612037]that's really friggin cool, but what interested me just as much is how the phone recognized the song even with all that static. how does that work?[/QUOTE]
the static is constant. Its smart enough to match the changes and listen a second at a time.
Imagine the beginning of seven nation army. Only so many songs have spikes in volume at exactly those points, so once it scans for all those songs, all thats left is to find one thing that that song does different than the rest and it knows that its probably that super popular song.
Sure under pressure is faster and more complex, but its the same principle.
