- Detect when browser pauses muted stream (throttling)
- Auto-reconnect after 3 seconds when paused while muted
- Apply to all three players for consistency
- Implement isReconnecting flag to prevent duplicate reconnect attempts
- Add exponential backoff for error retries (3s, 6s, 12s, max 30s)
- Retry indefinitely until stream returns
- Handle error, stalled, and ended events consistently
- Reset state on successful playback
- Apply same logic to frame player, popout player, and front-page player
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.
Optimized the timeout after stream reconnection to make the pause/unpause
experience more responsive. The 200ms delay is sufficient for the browser
to clear buffers and start the fresh stream while minimizing perceived lag.
- Detect pauses longer than 10 seconds across all player modes
- Intercept 'playing' event to stop stale buffered audio
- Force stream reconnect to get live audio after long pause
- Reset and reinitialize spectrum analyzer during reconnect
- Prevent 'Now Playing' updates while stream is paused
- Move spectrum-analyzer.lisp to parenscript/ directory
- Update all documentation dates to 2025-12-06
- Add comprehensive project statistics (408 commits, 9,300 LOC)
- Add Phase 9 (Visual Audio Features) to project history
Fixes issue where resuming playback after a long pause would play
old buffered audio instead of the current live stream. The fix uses
the 'playing' event to detect when stale audio starts and immediately
stops it, then reconnects to get fresh stream data.
All player modes updated: main player, front page, popout, and frame player.
- 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
