546c80e4ae feat: display dB values and use gauge icon for level meters
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.

dc567d0144 feat: add professional gradient to level meters matching dB scale
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

- 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!

fa397a1dfe fix: always show level meter and increase track height to 180px
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.

166385d29a fix: drag-to-select now works reliably without Shift key
Fixed async state update issue where selections were being cleared
immediately after creation. The mouseUp handler now checks drag
distance directly instead of relying on async state, ensuring

1dc0604635 feat: add intuitive drag-to-select on waveforms
Improved selection UX to match professional DAWs:
- Drag directly on waveform to create selections (no modifier keys needed)
- Click without dragging seeks playhead and clears selection
- 3-pixel drag threshold prevents accidental selections
- Fixed variable name conflict with existing file drag-and-drop feature

cbcd38b1ed refactor: remove master effects section, add TODO note
Removed the master effects section from AudioEditor footer:
- Simplified footer to only show transport controls
- Removed master channel strip area
- Removed border separator between sections

Added note to PLAN.md:
- 🔲 Master channel effects (TODO)
- Will implement master effect chain UI later
- Similar to per-track effects but for final mix
- Documented in Phase 7 multi-track features section

This cleans up the UI for now - we'll add master effects
with a proper device rack UI later, similar to how per-track
effects work (collapsible section with horizontal device cards).

ee24f04d76 feat: add automatic waveform repaint on theme change
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!

2a0d6cd673 fix: replace hardcoded colors with theme variables in Track component
Replaced hardcoded slate colors with theme-aware variables:

Track.tsx changes:
- Waveform area: bg-slate-900 → bg-waveform-bg
- Effects section: bg-slate-900/50 → bg-muted/50
- Expanded effects: bg-slate-900/30 → bg-muted/70
- Canvas background: rgb(15, 23, 42) → --color-waveform-bg

This ensures that:
- Light theme shows proper light gray backgrounds
- Dark theme shows proper dark gray backgrounds
- All components respect theme colors
- No more hardcoded colors that bypass the theme

Now the entire UI properly responds to theme changes with
the harmonized gray palettes we configured.

439c14db87 feat: show effect chain in collapsed state and polish visual integration
Visual improvements:
- Effects section background now matches waveform (slate-900/50)
- 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:
- When collapsed, shows mini effect chips in the header
- 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

Better integration:
- Background colors tie to waveform area
- Subtle hover effect on header (accent/30)
- Visual hierarchy: waveform -> effects blend together
- No more "abandoned" feeling - feels like part of the track

b9ffbf28ef feat: move effects section to collapsible area below track waveform
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

This provides a cleaner workflow where users can focus on mixing
when effects are hidden, then expand to full device view when needed.

  - 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.
