Oceanic - Ambient Focus Desktop App

Oceanic is a modern ambient sound and scene player built as a desktop app with Tauri + React + TypeScript. It helps you focus, relax, and sleep with layered sound mixing, curated visual scenes, timers, fade-out controls, and tray-first playback controls.

Features

• Real-time ambient mixer with grouped sounds and per-sound volume control
• Scene library with preview, search/filter, favorites, quick actions, and fullscreen playback modal
• Sleep timer with optional fade-out over configurable duration
• Auto-play on launch and persisted local preferences
• Native system tray integration (show/hide, play/pause, quit)
• Optional launch-on-startup support
• Multiple utility pages: Mixer, Scenes, Timer, and Settings
• Custom desktop titlebar and frameless Tauri window UX

Desktop Behavior

Oceanic combines frontend state with native desktop controls:

1. Playback state and preferences

• Frontend audio playback is managed in React (src/App.tsx) with per-sound HTMLAudioElement instances.
• User preferences are managed via useOceanicPreferences and persisted locally.

2. Tray-first workflow

• Rust backend creates tray menu actions for:
  • show window,
  • hide window,
  • play/pause all sounds,
  • quit app.
• Tray play/pause emits oceanic://toggle-playback which the React app listens to.

3. Close-to-tray behavior

• Closing the main window does not quit when minimizeToTray is enabled.
• The window hide behavior is handled in src-tauri/src/lib.rs (WindowEvent::CloseRequested).

4. Startup behavior

• Launch-on-startup is handled with @tauri-apps/plugin-autostart.
• If launched with autostart arg and startMinimized is enabled, the window starts hidden.
