When I click through, all I get is a black screen that says "Failed to start listening thread."

Nice!

We’re you inspired by the GuitarTuna iPhone app?

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 called from Rust compiled to WASM).

For pitch detection:

- https://crates.io/crates/pitch-detection

Do you have any plans on open sourcing the code?

I would love to see the source code, or at least a simplified version. Audio input in rust and rust talking with flutter on mobile device. Such a cool project.

iStrobosoft is the best tuning app. No contest.

Yes, I did the app mostly for myself as I was getting disappointed with them adding too many unnecessary (IMO) features to it.

So how do you tune 7 string guitars? :)

Maybe in future version :)

I don't think it's related, but a post from someone showing a simplified version of the same idea (pitch detection with WASM/Rust), with detail and source: https://www.toptal.com/webassembly/webassembly-rust-tutorial...
