Correlation is calculated using FFTs, so wouldn't that be just as slow?
Computations can be reduced if you only care about frequencies near 6 particular ones (and maybe some harmonics).
As an alternate tuning person I’d love a simple ‘this is the note you are playing’ I hate having to pick the tuning as I just wanna know a c#, g#, c#, f, g#, c# Please :)
This might have an obvious answer for the more experienced here, but (potentially stupid question) why didn't you use dart for this? Nothing against rust, just interested is all considering the dart/flutter relationship.
Speaking only for myself, I'm considering Flutter + Rust because I want to write everything in Rust, but there aren't great GUI options for Rust atm. I've heard good things about the rust dart bridge so it seems like a reasonable compromise, esp. given the Dart code to write Flutter UIs seems fairly declarative. Hoping to keep most of the logic in Rust and just the view in Flutter/Dart.

You'd get shit tuner if you do that. Ain't nobody got time to define scales on a fucking tuner
The movement is really choppy on my iPhone 13 Pro. Did you use requestAnimationFrame for the tuning movement? & CSS animations for switching instruments? Kinda just wondering how the performance could be so bad. Reminds me of PhoneGap circa 2013
I can confirm. It is extremely choppy and resource hungry for what it does. Since they use Flutter, the UI is rendered using 119 canvas elements. The same thing could be implemented using the web platform (no flutter and no rust) with better results.
I know the trend on HN is to upvote any project with Rust in the title, and to hate on native JS, but projects like this that have to use a bunch of tooling to eventually compile down to JS would have almost always been better just using JS in the first place IMO.

Flutter is not web-based. It's all custom.
But I suspect these people were trying the web version of this (pretty neat, IMO) app.
Flutter does build for the web but then it does (of course) use web technologies to deliver the UI. To get the native experience on iOS, you'd have to download the iOS version from the App Store or something like that.
Purchased for Android, love Flutter and been trying to learn guitar off/on, so this could be helpful. Question re: web (where I have not been impressed with Flutter as a platform) - I just get "Failed to start listening thread." I tried both Firefox and Chrome, latest versions. Side note: Also noticed I can't highlight/copy the text (common usability/accessibility issue with Flutter Web. I believe it's not that hard…
Of course, this is a cool project for more insight into the technologies involved regardless.
Also, you might want to consider polyphonic tuning. That's what would set you apart from everybody else. I bought a TC Electronic PolyTune earlier this year and it's been a game changer. It's much faster and easier to get tuned
Looks very nice, would you tell us a little bit about what you used to build this? I am just getting started with Rust and it would be cool to hear what approach you went and what you would recommend when starting today.
Flutter for the UI. Rust for the listening, and pitch detecting backend. Connected the former with the latter using flutter_rust_bridge. More details on Rust backend: For listening (getting audio signal from microphone) I used: - Android: https://crates.io/crates/oboe - native desktop/iOS (not currently released): https://crates.io/crates/clap - Web: https://crates.io/crates/web-sys (so basically JS Web Audio API cal…
I hope you didn't use a command line parser to stream audio...
