- 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
Changed from static file generation to Radiance API endpoint.
Parenscript now generates JavaScript in-memory at runtime when
the /api/asteroid/spectrum-analyzer.js endpoint is requested.
This is the correct approach for Parenscript integration with Radiance.
Implements real-time audio visualization for the main page:
- Added Parenscript dependency to asteroid.asd
- Created spectrum-analyzer.lisp with Parenscript code
- Added canvas element to front-page.ctml above nav buttons
- Auto-generates JavaScript at compile time
- Green gradient bars matching Asteroid aesthetic
- Uses Web Audio API for FFT analysis
This is the first Parenscript component in Asteroid Radio,
demonstrating the approach for future JavaScript conversions.
