feat(test_demo): Add audio/visual sync debug tool with tempo testing
Implements minimal standalone executable for debugging audio/visual
synchronization and variable tempo system without full demo complexity.
Key Features:
- Simple drum beat (kick-snare) with crash landmarks at bars 3 and 7
- NOTE_A4 (440 Hz) reference tone at start of each bar for testing
- Screen flash effect synchronized to audio peaks
- 16 second duration (8 bars at 120 BPM)
- Variable tempo mode (--tempo) alternating acceleration/deceleration
- Peak logging (--log-peaks) for gnuplot visualization
Command-line options:
- --help: Show usage information
- --fullscreen: Run in fullscreen mode
- --resolution WxH: Set window resolution
- --tempo: Enable tempo variation test (1.0x ↔ 1.5x and 1.0x ↔ 0.66x)
- --log-peaks FILE: Export audio peaks with beat timing for analysis
Files:
- src/test_demo.cc: Main executable (~220 lines)
- assets/test_demo.track: Drum pattern with NOTE_A4
- assets/test_demo.seq: Visual timeline (FlashEffect)
- test_demo_README.md: Comprehensive documentation
Build: cmake --build build --target test_demo
Usage: build/test_demo [--help] [--tempo] [--log-peaks peaks.txt]
