Hidden 'BopSpotter' Microphone Is Constantly Surveilling San Francisco For Good (404media.co) 44
An anonymous reader quotes a report from 404 Media: Somewhere over the streets of San Francisco's Mission, a microphone sits surveilling ... for banger songs. Bop Spotter is a project by technologist Riley Walz in which he has hidden an Android phone in a box on a pole, rigged it to be solar powered, and has set it to record audio and periodically sends it to Shazam's API to determine which songs people are playing in public. Walz describes it as ShotSpotter, but for music. "This is culture surveillance. No one notices, no one consents. But it's not about catching criminals," Walz's website reads. "It's about catching vibes. A constant feed of what's popping off in real-time."
ShotSpotter, of course, is the microphone-based, "gunshot detection" surveillance company that cities around the country have spent millions of dollars on. ShotSpotter is often inaccurate, and sometimes detects things like fireworks or a car backfiring as gunshots. Chicago, one of ShotSpotter's biggest clients, is finally allowing its contract with the company to end. Bop Spotter, on the other hand, is designed to figure out what cool music people are blasting from their cars or as they walk down the street. "I am a chronic Shazam-er. Most songs I listen to come from first hearing them at a party, store, or on the street," Walz told 404 Media. "Years ago I had the thought that it'd be cool to Shazam 24/7 from a fixed location, and I recently learned about ShotSpotter, and thought it'd be amusing to do what they do with music instead of gunshots. Was a great weekend project."
Walz said that the phone itself is rigged to a solar panel, and that it records audio in 10-minute blocks while in airplane mode. "Then it connects to WiFi to send the file to my server, which then split it into 20-second chunks that get passed to Shazam's API. The device doesn't Shazam directly, that would use way too much power. Probably $100 of parts," he said. BopSpotter's website has a constant feed of songs it hears, as well as links to play the songs in Spotify or Apple Music. As I'm writing this, BopSpotter has picked up "Not Like Us" by Kendrick Lamar, "The Next Episode" by Dr. Dre, and "Never Gonna Give You Up" by Rick Astley (a Rick Roll already?) among dozens of songs in the last few hours. The site also has a constant feed of the device's power levels. So far in three days, it has detected 380 songs. "I thought the solar panel would be annoying but it provides 4 times more power than the phone needs," Walz said. "The hardest part was scoping out which pole to actually put it up on. I had to balance finding a busy location where lots of music could be picked up, with enough sunlight, and good connection to a public wifi network."
Walz didn't say where exactly the phone is located.

Indeed no-one consents (Score:3)
Nobody is ever asked whether they consent to be put under surveillance anymore. So nothing new there.
But in this particular instance, he set up his gear in a public space where nobody has any expectation of privacy. So it's fair enough. Still, if the dude was recording people's conversations instead of random music soundbites, although legal, it would be super creepy.
Then again, there isn't much in the surveillance economy that isn't creepy as hell...

Maybe "expectation of privacy" shouldn't be binary, and maybe you should still have *some* even when walking in public. And, okay, it's debatable whether surveillance of public spaces for crime detection should be allowed or not.
But some fucking hipster blanket recording everything that happens nearby for purpose of "catching vibes" [sic!] without any kind of oversight at all, definitely lies on the "absolutely should NOT be allowed" side of the discussion.

Should the ATM across the street be allowed to have a camera which is able to see us, over here on this side of the street? And what about that residence which has a Ring camera on its door? It's seeing us from way over there!
Shit, it gets even worse. I thought this was a deaf pile of newspapers here next to us, but I just found a guy sleeping underneath it. Do you think he heard us?

What is the effective focal range of a "Ring", or an ATM camera? You'd want about 0.5m to around 3m - which is not challenging optics. If the design uses a 50-money camera that can focus out to 15m (for "the other side of the street") where a 10-money camera would have covered the useful range, you have to ask - why?

Recording police officers is a completely separate matter and legal in most states, because they're public employees and have not expectation of privacy when doing their official duties.

Pay attention to the section under "Recording may require permission" which links to this page outlining every state's recording laws [upcounsel.com].

No.
Since the recording of the conversation was incidental to the legitimate purpose of making the recording, it is not illegal to have recorded it.

Privacy is not a boolean. Even in public spaces I expect a certain level of privacy. I expect that only the people within sight / earshot can see and hear me, and only then. I expect to notice when someone is taking a picture of me.
But then, the US is the only country in the world where a judge tells you what you expect.

Arguably, if you've got people playing music loudly in public, loud enough to be picked up and identified on a utility pole over the ambient noise of the city, it's disturbing the peace - almost certainly loud enough to count as a disturbance.
It's also, in my experience, going to be a fairly "ethnic" identification. You don't have people blaring Taylor Smith or Angel Vivaldi, it's going to be hood music.
At best, this is likely to pick up on top 50 radio songs due to constr

Public performance of music is illegal without a license.
The PRS, who frequently phone up companies to listen over the phone if they have music audible then demand license payments, would love to have things like this in the streets.
They could tie the performances to BT/wifi MAC addresses, CCTV, all sorts.
I can see someone rubbing their hands with glee right now.

Playing loud music in a shared public space should be a specific offence, or at least a recordable misdemeanor. Both car stereos and loud music played from mobile phones.
