Added comprehensive playback level monitoring system that shows
real-time audio levels during playback for each track.
useMultiTrackPlayer Hook:
- Added AnalyserNode for each track in audio graph
- Implemented RMS-based level calculation with requestAnimationFrame
- Added trackLevels state (Record<string, number>) tracking levels by track ID
- Insert analysers after effects chain, before master gain
- Monitor levels continuously during playback
- Clean up level monitoring on pause/stop
Audio Graph Chain:
source -> gain -> pan -> effects -> analyser -> master gain -> destination
AudioEditor Integration:
- Extract trackLevels from useMultiTrackPlayer hook
- Pass trackLevels down to TrackList component
TrackList & Track Components:
- Accept and forward trackLevels prop
- Pass playbackLevel to individual Track components
- Track component displays appropriate level:
* Recording level (with "Input" label) when armed/recording
* Playback level (with "Level" label) during normal playback
Visual Feedback:
- Color-coded meters: green -> yellow (70%) -> red (90%)
- Real-time percentage display
- Seamless switching between input and output modes
This completes Phase 8 (Recording) with full bidirectional level monitoring!

Created a beautiful effect browser dialog inspired by Ableton Live:
**EffectBrowser Component:**
- Modal dialog with search functionality
- Effects organized by category:
- Dynamics (Compressor, Limiter, Gate)
- Filters (Lowpass, Highpass, Bandpass, etc.)
- Time-Based (Delay, Reverb, Chorus, Flanger, Phaser)
- Distortion (Distortion, Bitcrusher)
- Pitch & Time (Pitch Shifter, Time Stretch)
- Utility (Normalize, Fade In/Out, Reverse)
- Grid layout with hover effects
- Real-time search filtering
- Click effect to add to track
**Integration:**
- "+" button in track strip opens EffectBrowser dialog
- Selecting an effect adds it to the track's effect chain
- Effects appear immediately in the Devices section
- Full enable/disable and remove functionality
**UX Flow:**
1. Click "+" in track Devices section
2. Browse or search for effect
3. Click effect to add it
4. Effect appears in Devices list
5. Toggle on/off with ●/○
6. Remove with × button
Effects are now fully manageable in the UI! Next: Apply them to audio.

Major UX refactor to match professional DAW workflows (Ableton/Bitwig):
**Layout Changes:**
- Removed sidebar completely
- Track actions moved to header toolbar (Add/Import/Clear All)
- Each track now shows its own devices/effects in the track strip
- Master section moved to bottom footer area
- Full-width waveform display
**Track Strip (left panel):**
- Track name (editable inline)
- Color indicator
- Collapse/Solo/Mute/Delete buttons
- Volume slider with percentage
- Pan slider with L/C/R indicator
- Collapsible "Devices" section showing track effects
- Shows effect count in header
