Overchords shows playing notes from the speaker output in a piano view.

The rust backend uses the cpal library to capture the audio output and uses Basic-Pitch to detect the notes being played.

Download the install for your platform on the releases page.

Development

Building

You'll need Rust and Cargo (install via rustup.rs) and Bun to run the application locally.

Install the dependencies: bun install

Run the application: bun tauri dev

Publishing a release

Update the version in src-tauri/Cargo.toml, package.json and src-tauri/tauri.conf.json.

Then, add a commit to the release branch and push it to the remote repository. The GitHub Action will automatically build the application for all platforms and create a new release on GitHub with the generated binaries attached. This is a draft release, so you can review it before publishing it. Once you're ready, you can publish the release on GitHub and the binaries will be available for download.
