|
|
objective:
|
|
- Ensure waveform rendering doesn't cause performance issues
|
|
- Optimize for terminal TUI environment
|
|
- Minimize CPU and memory usage
|
|
|
|
deliverables:
|
|
- Performance optimizations
|
|
- Memory management for waveform data
|
|
- Performance monitoring and testing
|
|
|
|
steps:
|
|
1. Profile waveform rendering performance
|
|
2. Optimize data point generation and updates
|
|
3. Implement waveform data caching
|
|
4. Add performance monitoring
|
|
5. Test with long audio files
|
|
|
|
tests:
|
|
- Performance: Measure CPU usage during playback
|
|
- Performance: Measure memory usage over time
|
|
- Load test: Test with 30+ minute audio files
|
|
|
|
acceptance_criteria:
|
|
- Waveform rendering < 16ms per frame
|
|
- No memory leaks during extended playback
|
|
- Smooth playback even with waveform rendering
|
|
|
|
validation:
|
|
- Profile CPU usage during playback
|
|
- Monitor memory over 30-minute playback session
|
|
- Test with multiple simultaneous audio files
|
|
|
|
notes:
|
|
- Consider reducing waveform resolution during playback
|
|
- Cache waveform data to avoid regeneration
|
|
- Use efficient data structures for waveform points
|
|
- Test on slower terminals (e.g., tmux)
