Major Changes:
- Convert all JavaScript files to Parenscript for better maintainability
- Move spectrum-analyzer to parenscript/ directory structure
- Add parenscript-utils.lisp for shared utilities
- Convert admin.js, player.js, front-page.js, auth-ui.js to Parenscript
- Convert profile.js, users.js, recently-played.js to Parenscript
Stream Reconnect Fixes (from merged PR):
- Add reset-spectrum-analyzer function to properly clean up Web Audio API
- Implement reconnect logic for pauses longer than 10 seconds
- Detect stale audio in 'playing' event and force stream reconnection
- Prevent 'Now Playing' updates while stream is paused
- Reduce reconnect delay to 200ms for faster response
- Add proper spectrum analyzer reset/reinit during reconnection
UX Improvements:
- Change live indicator from blink to smooth pulse (2s ease-in-out)
- Pulse animation like old PowerBook/MacBook sleep indicator
- Add MUTED indicator to spectrum analyzer when audio is muted
- Spectrum continues to flow even when muted (data still streaming)
- Red 'MUTED' text displayed in top-right corner of canvas
Technical Details:
- Parenscript files generate JavaScript via API endpoints
- All player modes updated: main player, front page, popout, frame player
- Improved audio context handling to only create once per element
- Added comprehensive error handling and logging
- Updated asteroid.asd to include parenscript module structure
Documentation:
- Updated all documentation dates to 2025-12-06
- Added PARENSCRIPT-EXPERIMENT.org documenting the conversion
- Updated PROJECT-HISTORY.org with Phase 9 (Visual Audio Features)
- Added comprehensive project statistics (408 commits, 9,300 LOC)
This conversion improves code maintainability by using Lisp throughout
the stack and makes it easier to share code between frontend and backend.
- Reduced Icecast burst-size from 64KB to 8KB to minimize buffer accumulation
- Fixed spectrum analyzer to only create MediaElementSource once
- Added resetSpectrumAnalyzer() function to allow reconnection
- Prevent now-playing info updates when stream is paused across all players:
* Player page
* Front page
* Pop-out player
* Frame player
* Admin page
- After pause >10s, reconnect stream and reinitialize spectrum analyzer
- Preserves spectrum analyzer functionality after pause/unpause
- Eliminates stuttering and buffer accumulation issues
- Implement Web Audio API-based spectrum analyzer with green gradient bars
- Add spectrum analyzer to front page and persistent player content frames
- Support cross-frame audio element access for frameset mode
- Add CORS headers to Icecast configuration for Web Audio API
- Serve Parenscript-generated JavaScript dynamically via API endpoint
- Canvas visualization appears below page title, above navigation
- Add <changeowner> section to fix 'run as root' error
- Remove complex mount configurations, let Docker handle automatically
- Fix log directory path from /var/log/icecast2/ to /var/log/icecast/
- Update docker-compose.yml to use main icecast.xml instead of minimal version
- Remove temporary minimal-icecast.xml workaround file
All three streams now working with clean main configuration:
- asteroid.aac (96kbps AAC - recommended)
- asteroid.mp3 (128kbps MP3 - compatible)
- asteroid-low.mp3 (64kbps MP3 - low bandwidth)
AAC streaming feature is now production-ready with proper Docker integration.
- Increase sources limit from 2 to 5 in icecast.xml
- Add explicit mount configurations for asteroid.aac and asteroid-low.mp3
- Configure proper stream metadata and settings for each mount point
This should resolve the 403 Forbidden errors for AAC and low quality streams.
- Add complete Docker Compose setup with official Liquidsoap image (savonet/liquidsoap:v2.2.5)
- Add Icecast2 streaming server configuration
- Create dual quality streams (128kbps and 64kbps MP3)
- Add comprehensive documentation in Org format
- Add simple start/stop scripts for easy management
- Update .gitignore to exclude music files and Docker artifacts
- Remove old shell scripts (moved to ~/asteroid-scripts/)
- System-agnostic solution works on any Docker-capable system
This provides a complete streaming solution that works consistently across
all platforms, including Arch Linux where Liquidsoap packages may not be available.
