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

Converted level meters from linear to logarithmic (dB) scale to
match professional audio software behavior and human hearing.
The Problem:
- Linear scale (0-100%) doesn't match perceived loudness
- Doesn't match professional DAW meter behavior
- Half-volume audio appears at 50% but sounds much quieter
- No industry-standard dB reference
The Solution:
- Convert linear amplitude to dB: 20 * log10(linear)
- Normalize -60dB to 0dB range to 0-100% display
- Matches professional audio metering standards
dB Scale Mapping:
0 dB (linear 1.0) = 100% (full scale, clipping)
-6 dB (linear ~0.5) = 90% (loud)
-12 dB (linear ~0.25) = 80% (normal)
-20 dB (linear ~0.1) = 67% (moderate)
-40 dB (linear ~0.01) = 33% (quiet)
-60 dB (linear ~0.001) = 0% (silence threshold)
Implementation:
- Added linearToDbScale() function to both hooks
- useMultiTrackPlayer: playback level monitoring
- useRecording: input level monitoring
- Formula: (dB - minDb) / (maxDb - minDb)
- Range: -60dB (min) to 0dB (max)
Benefits:
✅ Professional audio metering standards
✅ Matches human perception of loudness
✅ Consistent with DAWs (Pro Tools, Logic, Ableton)
✅ Better visual feedback for mixing/mastering
✅ More responsive in useful range (-20dB to 0dB)
Now properly mastered tracks will show levels in the
90-100% range, matching what you'd see in professional software.

Switched from Uint8Array to Float32Array for level monitoring
to get accurate, full-precision audio measurements.
The Problem:
- getByteTimeDomainData() uses Uint8Array (0-255)
- Byte conversion: (value - 128) / 128 has asymmetric range
- Positive peaks: (255-128)/128 = 0.992 (not full 1.0)
- Precision loss from byte quantization
- Mastered tracks with peaks at 0dBFS only showed ~50%
The Solution:
- Switched to getFloatTimeDomainData() with Float32Array
- Returns actual sample values directly in -1.0 to +1.0 range
- No conversion needed, no precision loss
- Accurate representation of audio peaks
Changes Applied:
- useMultiTrackPlayer: Float32Array with analyser.fftSize samples
- useRecording: Float32Array with analyser.fftSize samples
- Peak detection: Math.abs() on float values directly
Benefits:
✅ Full 0-100% range for properly mastered audio
✅ Higher precision (32-bit float vs 8-bit byte)
✅ Symmetric range (-1.0 to +1.0, not -1.0 to ~0.992)
✅ Accurate metering for professional audio files
Now mastered tracks with peaks at 0dBFS will correctly show
~100% on the meters instead of being capped at 50%.

Repositioned analyser nodes in audio graph to measure raw audio
levels before volume/gain adjustments.
The Problem:
- Analyser was after gain node in signal chain
- Track volume defaults to 0.8 (80%)
- Audio was scaled down before measurement
- Meters only showed ~50% of actual audio peaks
The Solution:
- Moved analyser to immediately after source
- Now measures raw audio before any processing
- Shows true audio content independent of fader position
Audio Graph Changes:
Before: source -> gain -> pan -> effects -> analyser -> master
After: source -> analyser -> gain -> pan -> effects -> master
Benefits:
✅ Meters show full 0-100% range based on audio content
✅ Meter reading independent of volume fader position
✅ Accurate representation of track audio levels
✅ Increased smoothingTimeConstant to 0.8 for smoother motion
This is how professional DAWs work - level meters show the
audio content, not the output level after the fader.

Changed level calculation from RMS to peak detection to show
more realistic and responsive meter values.
The Problem:
- RMS calculation produced values typically in 0-30% range
- Audio signals have low average RMS (0.1-0.3 for music)
- Meters appeared broken, never reaching higher levels
The Solution:
- Switched to peak detection (max absolute value)
- Peaks now properly show 0-100% range
- More responsive to transients and dynamics
- Matches typical DAW meter behavior
Algorithm Change:
Before (RMS):
rms = sqrt(sum(normalized²) / length)
After (Peak):
peak = max(abs(normalized))
Applied to Both:
- Recording input level monitoring (useRecording)
- Playback output level monitoring (useMultiTrackPlayer)
Benefits:
✅ Full 0-100% range utilization
✅ More responsive visual feedback
✅ Accurate representation of audio peaks
✅ Consistent with professional audio software

Fixed playback level meters staying at 0% by resolving React closure
issue in the monitoring loop - same pattern as the recording fix.
The Problem:
- monitorPlaybackLevels callback checked stale `isPlaying` state
- Animation loop would run once and never continue
- Dependency on isPlaying caused callback recreation on every state change
The Solution:
- Added isMonitoringLevelsRef to track state independent of React
- Removed isPlaying dependency from callback (now has empty deps [])
- Set ref to true when starting playback
- Set ref to false when pausing, stopping, or ending playback
- Animation loop checks ref instead of stale closure state
Monitoring State Management:
- Start: play() sets isMonitoringLevelsRef.current = true
- Stop: pause(), stop(), onended, and cleanup set it to false
- Loop: continues while ref is true, stops when false
This ensures the requestAnimationFrame loop runs continuously
during playback and calculates real-time RMS levels for all tracks.

Added migration logic to useMultiTrack hook:
- When loading tracks from localStorage, check if height < DEFAULT_TRACK_HEIGHT
- Automatically upgrade old heights (120px, 150px) to new default (180px)
- Preserves custom heights that are already >= 180px
This fixes the inline style issue where existing tracks had
style="height: 120px" that was cutting off the level meter.
After this update, refreshing the page will automatically upgrade
all existing tracks to the new height without losing any data.

- 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
