Probably a smart idea to be suspicious of new apps, though I will say I am someone who care deeply about privacy. You can take a look at my previous project Boop ( https://boop.okat.best/ ), which is open source and has been on the App Store for 6 years, yet I still don't have any analytics or data collection in it. I have no clue how many people use it beyond download figures I get from Apple. I have considered maki…

> I'm worried that somebody will see my code But you're not worried that HN folks might run the app through a decompiler and find something approximately as revealing as your source code would be? The results might not be ideal depending on how much obfuscation you use, but I think it would be enough for someone to get the gist of how to replicate.

I have no issue with people decompiling my code for fun or curiosity. I often put easter eggs in my code or built files for this specific purpose. I never use obfuscation unless there is a security component.

The important part is the rest of that sentence, I have an issue with people who steal the code (or concepts) and charge money for it. If I do end up open-sourcing the code later, people will see the code and I have no issue with that.

This is awesome. As a fellow (dare I say luddite), technologist that hates the centralized greed digital internet tech has enabled with media, vinyl records are an outstanding hold out for individuals to still archive (and OWN!) their music. Thank you for investing in the movement with your valuable hours in making this app.

ShazamKit, from that fetch the BPM, BPM detection from the mic, compare ?

"Grooved does not use any third party library or API, just the built-in components provided by Apple."

ShazamKit is not third party, it is provided by Apple. Their website states "The audio stream is processed locally on your device and never recorded.", though this could refer to the audio statistics being collected locally, I assume ShazamKit still contacts an Apple API to get the classification.

Are there really "standard" BPM? As far as I know, most music production is just "whatever tempo the band feels like playing." I haven't been in a recording studio, though, so maybe a use of a metronome is more common there?

I'm not in the music industry in any capacity myself, so take everything I say here with a grain of salt. And more specifically, to address your question, I don't know enough about the recording part of music production to say whether most performers get a click-track played into their monitors or not. (I know that I've seen at least some performers using click-tracks for studio recording; but I'm not sure if that's…

> In those, the percussion (if any) isn't driving the performance

Wrong, drums (or the bass) most usually is driving the rhythm, and jazz musicians are extremely adept at staying on tempo.

> Because the jazz artists won't stay on beat, and this irritates some perfect-pitch-like "out of tune" feeling in the classical musician?)

Try the exact opposite. https://www.youtube.com/watch?v=rEbUNDW9bDA

> you'd have to fight the DAW to not.

That's just outright false. This is a basic action in all commonly used DAWs. eg https://promixacademy.com/blog/how-to-nudge-tracks-in-logic-...

Just put a record on yesterday and my wife said it was playing too fast. I thought she was wrong, then I see this post today! I grabbed the app and gave it a go, 3.5% too fast according to your app. Now I have to figure out how to adjust the damn thing. Really appreciate a free nonsense free app. update: youtube to the rescue. pretty common affordable turntable( Audio-Technica LP60), so I figure I would put the vid l…

Correct. That was often done when mastering with tape. Record at one speed, playback at another to make it sound more "lively." There are songs that were sped up that way anywhere from 25 to 40 cents. It's another reason why live music so often doesn't sound like the recording. When using digital mastering, you can also adjust the playback speed, but you can correct the shift. You get more "liveliness" without the sh…

I could swear the music video version of Evil by Interpol is faster than the album version, but it’s just inconvenient enough to verify that I haven’t bothered

comparing runtimes should do

So many recordings (especially before 2000) seem to be sped up a little. I can’t tell by listening to the song but when you try to play along with a guitar, it sounds terrible. Sometimes it helps to find a live version on YouTube.

What are cents in the context of playback speed? Hundredths of an RPM?
