21 hours	feat(audio): Add SilentBackend, fix peak measurement, reorganize backends	skal
	## Critical Fixes Peak Measurement Timing: - Fixed 400ms audio-visual desync by measuring peak at playback time - Added get_realtime_peak() to AudioBackend interface - Implemented real-time measurement in MiniaudioBackend audio callback - Updated main.cc and test_demo.cc to use audio_get_realtime_peak() Peak Decay Rate: - Fixed slow decay (0.95 → 0.7 per callback) - Old: 5.76 seconds to fade to 10% (constant flashing in test_demo) - New: 1.15 seconds to fade to 10% (proper visual sync) ## New Features SilentBackend: - Test-only backend for testing audio.cc without hardware - Controllable peak for testing edge cases - Tracks frames rendered and voice triggers - Added 7 comprehensive tests covering: - Lifecycle (init/start/shutdown) - Peak control and tracking - Playback time and buffer management - Integration with AudioEngine ## Refactoring Backend Organization: - Created src/audio/backend/ directory - Moved all backend implementations to subdirectory - Updated include paths and CMakeLists.txt - Cleaner codebase structure Code Cleanup: - Removed unused register_spec_asset() function - Added deprecation note to synth_get_output_peak() ## Testing - All 28 tests passing (100%) - New test: test_silent_backend - Improved audio.cc test coverage significantly ## Documentation - Created PEAK_FIX_SUMMARY.md with technical details - Created TASKS_SUMMARY.md with complete task report Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
3 days	perf: Reduce audio test durations for faster test suite	skal
	Optimized long-running audio tests to significantly improve test suite performance while maintaining test coverage. Changes: - WavDumpBackend: Added set_duration() method with configurable duration - Default remains 60s for debugging/production use - Test now uses 2s instead of 60s (140x faster: 60s → 0.43s) - JitteredAudioBackendTest: Reduced simulation durations - Test 1: 2.0s → 0.5s (4x faster) - Test 2: 10.0s → 3.0s (3.3x faster) - Overall: 14.49s → 4.48s (3.2x faster) - Updated assertions for shorter durations - Progress indicators adjusted for shorter tests Results: - Total test suite time: 18.31s → 8.29s (55% faster) - All 20 tests still pass - Tests still properly validate intended behavior handoff(Claude): Optimized audio test performance to speed up development iteration without sacrificing test coverage. WavDumpBackend now has configurable duration via set_duration() method.
4 days	feat: Optional sequence end times and comprehensive effect documentation	skal
	This milestone implements several key enhancements to the sequencing system and developer documentation: ## Optional Sequence End Times (New Feature) - Added support for explicit sequence termination via [time] syntax - Example: SEQUENCE 0 0 [30.0] forcefully ends all effects at 30 seconds - Updated seq_compiler.cc to parse optional [time] parameter with brackets - Added end_time_ field to Sequence class (default -1.0 = no explicit end) - Modified update_active_list() to check sequence end time and deactivate all effects when reached - Fully backward compatible - existing sequences work unchanged ## Comprehensive Effect Documentation (demo.seq) - Documented all effect constructor parameters (standard: device, queue, format) - Added runtime parameter documentation (time, beat, intensity, aspect_ratio) - Created detailed effect catalog with specific behaviors: * Scene effects: HeptagonEffect, ParticlesEffect, Hybrid3DEffect, FlashCubeEffect * Post-process effects: GaussianBlurEffect, SolarizeEffect, ChromaAberrationEffect, ThemeModulationEffect, FadeEffect, FlashEffect - Added examples section showing common usage patterns - Documented exact parameter behaviors (e.g., blur pulsates 0.5x-2.5x, flash triggers at intensity > 0.7, theme cycles every 8 seconds) ## Code Quality & Verification - Audited all hardcoded 1280x720 dimensions throughout codebase - Verified all shaders use uniforms.resolution and uniforms.aspect_ratio - Confirmed Effect::resize() properly updates width_/height_ members - No issues found - dimension handling is fully dynamic and robust ## Files Changed - tools/seq_compiler.cc: Parse [end_time], generate set_end_time() calls - src/gpu/effect.h: Added end_time_, set_end_time(), get_end_time() - src/gpu/effect.cc: Check sequence end time in update_active_list() - assets/demo.seq: Comprehensive syntax and effect documentation - Generated files updated (timeline.cc, assets_data.cc, music_data.cc) This work establishes a more flexible sequencing system and provides developers with clear documentation for authoring demo timelines. handoff(Claude): Optional sequence end times implemented, effect documentation complete, dimension handling verified. Ready for next phase of development.
