+# 06. Implement Audio Waveform Analysis
+
+meta:
+  id: merged-waveform-06
+  feature: merged-waveform
+  priority: P2
+  depends_on: []
+  tags: [audio, waveform, analysis]
+
+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
