Ex Shazam tech here. The signatures that the Shazam app sends are very small, so bandwith costs should be minimal. Of course, I speaking about the technology of my day 2001+, so times may have changed

It seems to also send the actual sound samples though.

The audio samples are ~250 kB each. A single photo would probably be larger.

somebody needs to do this at a couple of starbucks in key areas, record anon conversations and build a browsable map of topics

I can already see Matt Levine's column: if someone places secret recorders at Starbucks and leaks the transcript to the internet, is it insider trading?

I've listened to a bunch of the snippets and you can usually just barely hear the sound in the background. Which makes me think Shazam is very accurate. I really should read more about how Shazam's algorithm works, because it feels like magic. The phone records 10 minute chunks of audio at a time, in airplane mode. Every 10 minutes, airplane mode is turned off and the audio is uploaded to a server. The server then sp…

will be interesting to see how it fares in the winter!

A San Francisco winter? The mean daily minimum is something like 45F, it's more likely to have trouble overheating during the summer.

I love everything about this. There is this undercurrent to our technology landscape. A kind of subculture somewhere in the locus of the hackersphere where a kind of punk-rock ethos rules the roost. I can only describe it as a live exploration of concepts _through_ technology, where functional fixedness is a foreign concept, including in the shared experience of social construct; everything becomes parts to be remixe…

Funnily enough I've also heard throwies cited as evidence of some kind of cultural decline - "not a real hack" etc.

How do I join the party? Is there a quickstart so you can hear the vibes of Berlin? [edit: It would be awesome if others could collaborate on this and had a guide on how to do it!]

I recommend you sit this one out, as recording people, even if only audio and sending the sound over the internet is very much against the law in germany

The legality of it only matters if you get caught. So don't use hardware or software that's traceable back to you, and be sufficiently careful to remain undetected when you install it. People often weigh the likelihood of being caught much, much higher than it actually is, and therefore conclude "I mustn't do anything illegal", which is irrational.

Quick bit of feedback: Google translate thinks this page is in Spanish (I wonder why). It’d be nice to not see that “translate this page” pop up. Otherwise, cool project!

I think I fixed this! nice catch

This is looking about 90% Spanish songs and 10% reggae-fusion.

I'm pretty amused at whoever decided to play KDA at 9:30 last night though.

That's funny because I recognized Annika Wells and had to look up the song without knowing who K/DA was.

from the example it didn't detect any music between 11:30pm and 9:30am. I don't know what corner of the mission that could possibly be.

> from the example it didn't detect any music between 11:30pm and 9:30am I thought it might have died because the site mentioned it is solar powered.

Battery only got down to 70% overnight, from another thread here.

Some details on how this works: https://twitter.com/rtwlz/status/1840821351055311245

    The phone has a Tasker script running on loop (even if
    the battery dies, it’ll restart when it boots again)

    Script records 10 min of audio in airplane mode, then
    comes out of airplane mode and connects to nearby free
    WiFi.

    Then uploads the audio file to my server, which splits it
    into 15 sec chunks that slightly overlap. Passes each to
    Shazam’s API (not public, but someone reverse engineered
    it and made a great Python package). Phone only uses 2%
    of power every hour when it’s not charging!
