|
objective:
|
|
- Analyze audio data to extract waveform information
|
|
- Create real-time waveform data from audio streams
|
|
- Generate waveform data points for visualization
|
|
|
|
deliverables:
|
|
- Audio analysis utility
|
|
- Waveform data extraction function
|
|
- Integration with audio backend
|
|
|
|
steps:
|
|
1. Research and select audio waveform analysis library (e.g., `audiowaveform`)
|
|
2. Create `src/utils/audio-waveform.ts`
|
|
3. Implement audio data extraction from backend
|
|
4. Generate waveform data points (amplitude values)
|
|
5. Add sample rate and duration normalization
|
|
|
|
tests:
|
|
- Unit: Test waveform generation from sample audio
|
|
- Integration: Test with real audio playback
|
|
- Performance: Measure waveform generation overhead
|
|
|
|
acceptance_criteria:
|
|
- Waveform data is generated from audio content
|
|
- Data points represent audio amplitude accurately
|
|
- Generation works with real-time audio streams
|
|
|
|
validation:
|
|
- Generate waveform from sample MP3 file
|
|
- Verify amplitude data matches audio peaks
|
|
- Test with different audio formats
|
|
|
|
notes:
|
|
- Consider using `ffmpeg` or `sox` for offline analysis
|
|
- For real-time: analyze audio chunks during playback
|
|
- Waveform resolution: 64-256 data points for TUI display
|
|
- Normalize amplitude to 0-1 range
