It might reflect different attitudes between cultures as to what volume makes one an "asshole".

I guess no one with loud music considers themself an asshole, so this should be actually giving the information on exactly what you mention.

I had a collogue who installed his speaker setup facing backwards out of his trunk. He knew what he was doing.

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 music fingerprinting on my Android phone works in airplane mode, so it would be possible with modifications. Also, it's likely that Shazam is sending a "hash" of the audio rather than an audio stream in most cases.

Its not a hash though? Its a reverse - fourier transform system that matches the sound- similar to the filter that filters out the vuvuzelas?

Like having a distinctive click impulse and get the cathedral from that.

Then you'd get someone taking the trouble to correlate music and times, to capture someone moving across the city on the map. Then you'd get profiling to potentially pick out who in particular moved across the city and the exact time of path of their movement. While this is a nice idea on a local scale, when scaled up it has horrendous privacy implications.

And music fingerprinting is probably incredibly accurate, because it can work similar to linguistic fingerprinting. There was a site posted to this place a year or so ago, which looked at work frequencies to find alt-accounts. I don't hide the fact that I use a different account on different computers, so I have a personal account and work accounts and end up changing accounts each time I change jobs. This site corre…

I enjoyed playing with that webapp [0], bummer that it's down now.

Nice idea - it'd be interesting to do some stats on matching accuracy, eg: September 29, 2024 6:53 PM La Banda Del Carro Rojo Los Tigres del Norte links to the captured street noise that matched .. and I (perhaps others can) cannot hear the asserted "match" https://www.youtube.com/watch?v=1Wjz9L0UOhE but bonus points for picking up that Virreinato de Nueva España vibe.

You can faintly hear the accordion near the end of the recording. I don't like that it shares the recordings though. It doesn't add much value and it's a privacy violation, even if it's legal.

See I’m not sure that it is legal. If they are re-transmitting audio is being played in public over the Internet for potentially many thousands more people, I’m pretty sure the RIAA, the UMG, & the WMG would all have something to say about it.

There are examples in several cultures of songs that boast of annoying others:

Other cultures seem to feel more entitled, thinking that THEIR music could not possibly bother anyone. I've certainly heard people blast Wagner or Orff at high volumes.

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!]

Especially on a Sunday

I just gave up on ever being able to really be anonymous, after I had a rather sobering interaction with Disqus.

I had never used it, and wanted to leave a comment on a site (long ago -can't remember where or when).

I started to sign up for Disqus, and it helpfully asked me "We found all these comments from around the Web. Should we associate these with this account?"

It included some old, dead-and-gone-I-would-have-sworn-it troll postings that I had pooped out, back in the last century.

I immediately deleted my signup, and went and had a lie-down.

These days, I deliberately make it obvious who I am, and post as if I had to stand behind my words.

Thank for finding that, yes that's the one. It was incredibly accurate.

I'm in two minds about the fact it's down.

1. It's probably a good thing that it isn't super-easy to quickly find everyone's alternate accounts.

2. The capability is clearly there and the technology is out there, but now in the hands of the few people who bother to re-implement it.

It was a useful tool for highlighting the naivety of believing that throwaway accounts were a real possibility when stylometry analysis is so relatively cheap to do.

Other than "it'd be fun to build", what would it bring to the table in comparison to say this Apple Music playlist? https://music.apple.com/us/playlist/top-25-berlin/pl.184d798...
