Create resources/sounds/ directory structure + - Add placeholder .gitkeep files + +2. **Soundpack class with tests** [P:mvp-2] + - Write tests for Soundpack class (TDD) + - Implement Soundpack class + - Test loading, validation, path retrieval + +3. **SoundpackManager class with tests** [P:mvp-3] + - Write tests for SoundpackManager (TDD) + - Implement SoundpackManager + - Test discovery, loading, switching + +4. **Find audio files** [P:mvp-4] + - Search for royalty-free classic chime sounds (bell/clock) + - Search for nature sounds (birds, wind chimes, water) + - Search for digital sounds (beeps, synth tones) + - Document sources and licenses in ATTRIBUTIONS.md + +5. **UI integration** [P:mvp-5] + - Update app.py to use SoundpackManager + - Connect Test Chime button to play hourly sound + - Update soundpack dropdown to load selected pack + - Add error handling and status feedback + +6. **Automatic chiming** [P:mvp-6] + - Implement time-based chime logic in clock update task + - Check interval switches (hourly/half/quarter) + - Play appropriate chime at correct time + - Prevent duplicate chimes (track last chime time) + +### Iteration 1: Testing & Polish +7. **Manual testing** [P:iter1-1] + - Test all three soundpacks load correctly + - Verify chimes play at correct times + - Test with NVDA screen reader + - Verify volume control affects chimes + +8. **Error handling** [P:iter1-2] + - Graceful handling of missing files + - User-friendly error messages + - Fallback to test beep if soundpack fails + +### Iteration 2: Documentation +9. **Documentation** [P:iter2-1] + - Update README with soundpack information + - Document how to add custom soundpacks + - Add troubleshooting section + +## Audio File Requirements + +### Classic Soundpack +- **Theme**: Traditional clock chimes (grandfather clock, church bells) +- **Hour**: Full chime sequence (e.g., Westminster chimes) +- **Half**: Shorter chime or single bell +- **Quarter**: Brief bell tone + +### Nature Soundpack +- **Theme**: Natural, calming sounds +- **Hour**: Bird calls or wind chimes (longer) +- **Half**: Gentle water sound or shorter bird call +- **Quarter**: Soft chime or nature accent + +### Digital Soundpack +- **Theme**: Modern, electronic tones +- **Hour**: Multi-tone digital sequence +- **Half**: Two-tone beep +- **Quarter**: Single tone beep + +### File Specifications +- **Format**: WAV (preferred) or OGG Vorbis +- **Sample Rate**: 44.1kHz or 48kHz +- **Bit Depth**: 16-bit minimum +- **Duration**: 1-5 seconds (longer for hourly) +- **Licensing**: CC0, CC-BY, or Public Domain + +### Search Sources +- Freesound.org (CC-licensed sounds) +- OpenGameArt.org (CC0 sounds) +- ZapSplat.com (free tier) +- BBC Sound Effects (free for personal use) +- sonniss.com GameAudioGDC (annual free bundles) + +## Testing Strategy + +### Unit Tests +- Soundpack class methods (load, validate, get_path) +- SoundpackManager discovery and switching +- Path resolution and file existence checks +- Error handling for missing/invalid files + +### Integration Tests +- App startup with soundpack loading +- Dropdown selection triggers soundpack change +- Test Chime button plays correct sound +- Automatic chiming at correct times +- Volume control affects chime playback + +### Manual Testing +- Listen to all sounds in all soundpacks +- Verify timing accuracy (chimes at :00, :15, :30, :45) +- Test with different interval switch combinations +- NVDA screen reader compatibility +- Performance with rapid soundpack switching + +## Success Criteria +- ✅ All three soundpacks have complete audio files +- ✅ Soundpacks load successfully on app startup +- ✅ User can switch soundpacks via dropdown +- ✅ Test Chime plays hourly sound of current soundpack +- ✅ Automatic chiming works correctly based on time +- ✅ All audio files properly attributed +- ✅ All unit tests passing +- ✅ Manual accessibility testing completed +- ✅ No errors in logs during normal operation + +## Dependencies +- Existing AudioPlayer class (Phase 2) +- pathlib for file system operations +- No new external packages required + +## Timeline Estimate +- Soundpack classes: 1-2 hours +- Audio file sourcing: 1-2 hours +- UI integration: 1 hour +- Automatic chiming: 1 hour +- Testing & polish: 1-2 hours +- **Total**: 5-8 hours + +## Risks & Mitigation +- **Risk**: Cannot find suitable free audio files + - **Mitigation**: Generate simple tones programmatically if needed +- **Risk**: Audio files too large, slow loading + - **Mitigation**: Compress/optimize files, lazy load on demand +- **Risk**: Chiming interrupts user workflow + -
