Add a comprehensive YAML reference file documenting package names
across different Linux distributions. This serves as:
1. Documentation for manual installation on unsupported distros
2. Reference for adding support for new distributions
3. Auxiliary reference for the installer's embedded package mappings
Completes Task 6 from the cross-distribution compatibility fix plan.
Related to: #158, #159, #160, #161
Add better error messages and documentation for cross-distribution compatibility.
**Task 9: System Dependency Checker (scripts/check-system-deps.sh)**
- New script to check system dependencies regardless of distribution
- Detects Python 3.8+, pkg-config, GTK3, PyGObject, PortAudio
- Checks for text injection tools (xdotool, wtype, ydotool)
- Provides distribution-specific installation instructions
- Supports all 10+ distribution families (Ubuntu, Debian, Fedora, Arch, openSUSE, Gentoo, Alpine, Void, Solus, Mageia)
**Task 10: Better Unsupported Distro Message (install.sh)**
- Enhanced error message for unsupported distributions
- References the new dependency checker script
- Provides manual installation options (skip-system-deps, venv install)
- Includes link to project wiki
- Interactive prompt to continue or cancel
**Task 11: Distro Compatibility Documentation (docs/DISTRO_COMPATIBILITY.md)**
- Comprehensive compatibility matrix for supported distros
- Experimental support section with known issues
- Requirements by distribution with exact commands
- Desktop environment compatibility (GNOME, KDE, Xfce, sway, i3, etc.)
- Display server support (X11, Wayland, XWayland)
- Architecture support (x86_64, arm64, armhf, riscv64)
- Testing checklist for new distributions
- Issue reporting guidelines
- Contributing guidelines for compatibility fixes
Part of cross-distribution compatibility improvements (Phase 3 of 5).
Related to #157
Replace the current jarring sound alerts with smoother, more pleasant
bell-like tones inspired by voice assistants like Siri and Gemini.
Changes:
- start_recording.wav: Ascending perfect fifth (A4→E5, 0.30s)
- stop_recording.wav: Descending perfect fifth (E5→A4, 0.25s)
- error.wav: Low gentle chime (E4, 0.35s)
Technical improvements:
- Smooth frequency sweeps (sigmoid curve transitions)
- Subtle vibrato (8Hz) for warmth and richness
- Harmonic overtones for fullness
- Elegant exponential decay envelopes
- Reduced file sizes (926KB → 80KB total)
The new sounds are shorter (0.25-0.35s vs 0.5-1s), quieter
(20-25% amplitude vs full volume), and more pleasant for frequent use.
