Fixed playhead marker alignment issue:
- Changed automation controls from w-[180px] to w-48 (192px)
- Now matches track controls panel width exactly
- Playhead marker now aligns perfectly between waveform and automation
Technical details:
- Track controls use Tailwind's w-48 class (12rem = 192px)
- Automation controls were using w-[180px] causing 12px misalignment
- Both sidebars now use consistent w-48 sizing

Changed level meter display to show professional dB values instead
of percentages, and replaced volume icon with gauge icon.
Display Changes:
- Show dB values (-60 to 0) instead of percentage (0-100%)
- Use monospace font for consistent digit alignment
- Show "-∞" for silence (level = 0) instead of "-60"
- Rounded to nearest integer dB (no decimals for cleaner display)
Icon Updates:
- Replaced Volume2 icon with Gauge icon for playback levels
- Kept Mic icon for recording input levels
- Gauge better represents metering/measurement vs audio control
dB Conversion:
- Formula: dB = (normalized * 60) - 60
- Reverse of: normalized = (dB + 60) / 60
- Range: -60dB (silence) to 0dB (full scale)
Display Examples:
0.00 (0%) = -∞ (silence)
0.17 (17%) = -50dB (very quiet)
0.50 (50%) = -30dB (moderate)
0.83 (83%) = -10dB (loud)
1.00 (100%) = 0dB (full scale)
Benefits:
✅ Professional dB notation matching industry standards
✅ Clearer for audio engineers and musicians
✅ Easier to identify levels relative to 0dBFS
✅ Gauge icon better conveys "measurement"
✅ Monospace font prevents number jumping
Now meters show "-18" instead of "70%" making it immediately
clear where you are in the dynamic range.

Replaced solid color blocks with smooth gradient to match
professional audio metering standards and dB scale mapping.
The Problem:
- Hard color transitions (green/yellow/red) looked jarring
- Didn't match professional DAW aesthetics
- Color didn't reflect actual dB values visually
The Solution:
- Implemented CSS linear gradient across meter bar
- Gradient matches dB scale breakpoints:
* Green: 0-70% (-60dB to -18dB) - Safe zone
* Yellow: 70-90% (-18dB to -6dB) - Getting hot
* Red: 90-100% (-6dB to 0dB) - Very loud/clipping
Gradient Details:
Horizontal: linear-gradient(to right, ...)
Vertical: linear-gradient(to top, ...)
Color stops:
0%: rgb(34, 197, 94) - Green start
70%: rgb(34, 197, 94) - Green hold
85%: rgb(234, 179, 8) - Yellow transition
100%: rgb(239, 68, 68) - Red peak
Visual Behavior:
- Smooth color transition as levels increase
- Green dominates safe zone (-60dB to -18dB)
- Yellow appears in warning zone (-18dB to -6dB)
- Red shows critical/clipping zone (-6dB to 0dB)
- Matches Pro Tools, Logic Pro, Ableton Live style
Benefits:
✅ Professional appearance matching industry DAWs
✅ Smooth visual feedback instead of jarring transitions
✅ Colors accurately represent dB ranges
✅ Better user experience for mixing/mastering
✅ Gradient visible even at low levels

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

Fixed layout issues with the level meter:
Track Height:
- Increased DEFAULT_TRACK_HEIGHT from 150px to 180px
- Ensures enough vertical space for all controls without clipping
Level Meter Display:
- Now always visible (not conditional on recording state)
- Shows "Input" with mic icon when track is armed or recording
- Shows "Level" with volume icon when not recording
- Displays appropriate level based on state
This prevents the meter from being cut off and provides consistent
visual feedback for all tracks. Future enhancement: show actual
playback output levels when not recording.

Implemented MutationObserver to detect theme changes:
- Added themeKey state that increments on theme change
- MutationObserver watches document.documentElement for class changes
- Detects when "dark" class is toggled
- Added themeKey to waveform effect dependencies
- Canvas automatically redraws with new theme colors
How it works:
1. Observer listens for class attribute changes on <html>
2. When dark mode is toggled, themeKey increments
3. useEffect dependency triggers canvas redraw
4. getComputedStyle reads fresh --color-waveform-bg value
5. Waveform renders with correct theme background
Benefits:
- Seamless theme transitions
- Waveform colors always match current theme
- No manual refresh needed
- Automatic cleanup on unmount
Now switching between light/dark themes instantly updates
all waveform backgrounds with the correct theme colors!

- More subtle border (border-border/50)
- Compact header (py-1.5 instead of py-2)
- Expanded area has darker background (slate-900/30) for depth
Collapsed state improvements:

- Each chip shows effect name with visual state:
- Enabled: primary color with border (blue/accent)
- Disabled: muted with border
- Chips are scrollable horizontally if many effects
- Falls back to "Devices (count)" when no effects

Major UX improvement inspired by Ableton Live's device view:
- Effects section now appears below the waveform in the track lane
- Toggle button in control panel shows/hides the effects area
- Gives much more horizontal space for device rack
- Effects section spans full width of track (control panel + waveform)
- Clean separation between track controls and effects
- Header with device count, add button, and close button
Layout changes:
- Track structure changed from horizontal to vertical flex
- Top row contains control panel + waveform (fixed height)
- Bottom section contains collapsible effects area (when shown)
- Effects hidden by default, toggled via "Devices" button
- When collapsed, track doesn't show effects section
