- ✅ Sample rate matching (44.1kHz, 48kHz, 96kHz)
- ✅ Recording settings panel shown when track is armed
**Analysis Tools (Phase 10 - Partial):**
**Analysis Tools (Phase 10 - Complete):**
- ✅ Frequency Analyzer with real-time FFT display
- ✅ Spectrogram with time-frequency waterfall visualization
- ✅ Phase Correlation Meter (stereo phase analysis)
- ✅ LUFS Loudness Meter (momentary/short-term/integrated)
- ✅ Audio Statistics Panel (project info and levels)
- ✅ Color-coded heat map (blue → cyan → green → yellow → red)
- ✅ Toggle between analyzer views in master column
- ✅ Toggle between 5 analyzer views (FFT/SPEC/PHS/LUFS/INFO)
- ✅ Theme-aware backgrounds (light/dark mode support)
- ✅ Peak and RMS meters (master and per-track)
- ✅ Clip indicator with reset (master only)
**Export Features (Phase 11.1 & 11.2 - Complete):**
- ✅ WAV export (16/24/32-bit PCM or float)
- ✅ MP3 export with lamejs (128/192/256/320 kbps)
- ✅ FLAC export with fflate compression (quality 0-9)
- ✅ Format selector dropdown with dynamic options
- ✅ Normalization option (1% headroom)
- ✅ Mix all tracks before export
- ✅ Export dialog with format-specific settings
- ✅ Dynamic file extension display
### Next Steps
- **Phase 6**: Audio effects ✅ COMPLETE (Basic + Filters + Dynamics + Time-Based + Advanced + Chain Management)
- **Phase 7**: Multi-track editing ✅ COMPLETE (Multi-track playback, effects, selection/editing)
- **Phase 8**: Recording functionality ✅ COMPLETE (Audio input, controls, settings with overdub/punch)
- **Phase 9**: Automation ✅ COMPLETE (Volume/Pan automation with write/touch/latch modes)
- **Phase 10**: Analysis Tools ✅ COMPLETE (FFT, Spectrogram, Phase Correlation, LUFS, Audio Statistics)
- **Phase 11**: Export & Import 🔄 IN PROGRESS (WAV complete, MP3/OGG/FLAC remaining)
- **Phase 11**: Export & Import 🔄 PARTIALLY COMPLETE (11.1 & 11.2 done: WAV/MP3/FLAC export with all settings)
