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.

That’s just how you install a subwoofer though?

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

Any volume which makes your music become my music too without my consent is at asshole level.

It might be that you’re the asshole in this situation. I think the boundaries are pourous around this topic.

(Sure, I just called someone random on the web an asshole. I don’t mean it with any force. In London we get people riding busses playing their im-personal stereos loudly, sometimes. I often don’t like it either. I often use headphones for my own sounds but not the blocking kind, and will have to stop my music because of thwirs. One time someone got into the Tube/metro carriage I was in playing loud Brazilian music from a speaker on a trolley. At first it annoyed me, but after a few bars it got me grooving. Then I realised it was a funk-infused cover of a traditional capoeira song, so I steuck up a conversation with the other rider about Brazil and capoeira. Made my day.)

How do you get the data out of the Shazam app (?)

I was wondering the same. Also curious about those battery stats:

> Battery currently at 80% (a decrease of 6% in the last 4 hours).

That's gotta be an OLED screen at lowest brightness or, even more likely, a fully black overlay app since the mic is constantly active and either locally processing it into Shazam and streaming fingerprints or (less cpu, more network) streaming it to a server which then does the processing and queries Shazam. As a comparison, my work phone is off+idle basically the whole time and takes twice as long to charge at a higher wattage as my personal phone (i.e.: large battery by my standards), and that uses nearly a percent per hour while the screen is off with maybe 20 messages and one email coming in across 4 hours.

I'm amazed by the idea, that no rate limit has kicked in on Shazam, that they didn't connect it to a power source, and that the battery is lasting so long!

Edit: missed that it is being powered by a solar panel

I played, more than once, a few of the sound snippets. I think the Shazam "findings" are highly inaccurate. Fun project nonetheless!

walz, could you write more about the setup, maybe to propitiate others to replicate it in other cities?

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

Which law are you thinking about in particular?

I expectation is that the microphone above the rooftop will not pick up on normal conversations, only louder stuff.

The phrase "turn down" is the opposite of "turn up". To "turn down" would be to decrease the intensity of the party. And "turn down for what" means something like "don't stop the party for any reason".

Pretty sure that's not the case here. To "turn down" is a common phrase (at least in the US) that is used to describe changing something by use of a control. As described at Wiktionary [0] - it's an idiomatic way of saying that you're going to lower the volume through use of a control to do that. The context that was used has nothing to do with party.

No, the above poster is talking about the Lil Jon song called "Turn down for what" and it's not about volume.

Same, although I know Shazam does most of its work on very high frequencies so it’s possible we’re not able to hear the part that got matched.

The “Not Like Us” snippet (09/29 2:43pm) is easily recognizable though. And “Rockabye” can be heard at 3:05pm.

Would that not mean that Shazaam is illegal Germany? From my limited searching it doesn't seem like it is.

Well it's you a person who is recording the music. So it's the user's responsibility to make sure you are not breaking any laws. So the app cannot be held at fault for this. No one cares if you do a Shazam in public so it all just works out. But if you set up an autonomous recording device, no matter what you say you are doing, you will have problems.

What law is that that's broken here?

This is really cool. Imagine a map of this across a city, being able to see what different areas tend to listen to. I imagine you'd find some surprising and not-so-surprising things.

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.

Then you'd get someone taking the trouble to correlate music and times, to capture someone moving across the city on the map.

Only if someone can move across the city in three minutes.
