I hope you didn't use a command line parser to stream audio...

I meant https://github.com/RustAudio/cpal (should've checked).

Haha, no worries :) "clap" does indeed sound audio-related, and "clap" is only one transposition from "cpal"!

"clap" IS actually audio related too https://github.com/free-audio/clap :)

Heh, I always get those two crates names confused, even now, rereading comments I again thought it was "clap" and not "cpal" (because "clap" like in "clapping").

>Flutter for the UI. Rust for the listening, and pitch detecting backend. Connected the former with the latter using flutter_rust_bridge.

It's good to see that there is a active project to help with making Android apps using rust.

Why not just dart?

Dart being a GC'd runtime makes it quite hard to use for low latency audio applications, probably not as critical for audio input as output, but still potential issue, for more details see: https://github.com/dart-lang/sdk/issues/46943

Then why bother with Flutter at all?

It's amazing for UI (and portable).

Rust - not so much (or more like not at all) at the moment.

And has a GC running all the time, including when the called Rust code is executing, making it pointless to avoid using Dart in first place.

Awesome, thanks!
