Marconio

A desktop internet radio that looks and feels like a piece of hardware you'd find in a late-2000s Honda. Marconio streams NTS Radio — both live channels and their catalog of mixtapes — through a native audio engine with a handful of audio effects you can toggle on the fly.

The whole thing fits in a small fixed-size window. There's an amber LCD, six preset buttons, a row of FX keys, and not much else.

Using it

The two left presets are locked to NTS Channel 1 and Channel 2 (live). The remaining four are yours — right-click to assign any NTS mixtape. Tap a preset to start listening. Tap the LCD to cycle through display themes (amber, blue, green, pink).

The FX row at the bottom lets you color the sound:

• Clean — straight through, no processing
• Mag — tape warble, gentle compression, a little warmth
• Bass+ — low-end boost with some saturation
• Radio — mid-heavy, compressed, like a speaker in a dashboard

Keyboard shortcuts work the way you'd expect: 1–6 for presets, Space to play/stop, Esc to close menus.

On macOS and Windows, Marconio can live in your menu bar / system tray instead of the dock. The tray icon shows which preset you're listening to, and right-clicking it shows the current track info and a shortcut into settings.

On macOS 12+, Marconio also has a manual FIND SONG button in the header. Press it while audio is playing to run ShazamKit recognition against the active stream. Matches are saved in the HITS panel so you can review them later.

Your preset assignments, display theme, and FX choice are remembered between sessions.

What might not work

• Stream drops — if your connection hiccups, the audio stops but the UI might still look like it's playing until you hit stop/play again. There's no automatic reconnect yet. Just restart the app!
• Linux — haven't tried it at all, in theory it might work.
• No volume knob — volume is whatever your system volume is. In-app control isn't implemented yet.
• Toolchain quirks on macOS — if you're building from source and hit a libclang architecture mismatch error, it's a Rust/Xcode toolchain issue, not a Marconio bug.
  • mise tasks force /opt/homebrew/bin and unset RUSTUP_TOOLCHAIN so local Tauri builds use arm64 Homebrew Rust tools by default.
• Shazam feature availability — song recognition requires macOS 12+ and an app signing profile with the ShazamKit capability enabled.
  • For local debugging of ShazamKit specifically, prefer mise run dev_signed (signed app bundle). mise run dev uses tauri dev, which runs an ad-hoc binary and may fail App Service checks.

Building from source

You'll need Rust (stable), Deno 2.x, and the Tauri prerequisites for your platform. Tool versions are pinned in mise.toml if you use mise.

For macOS development builds, this repo uses src-tauri/tauri.ci-development.conf.json by default in the mise development tasks. Make sure provisioning/ci-development-marconio.provisionprofile is present locally.
