Engine & algorithm:
- Use default shelf Q (1/√2) in calculateBiquadResponse for shelf filters
- Compute normalization offset on measurement frequency grid to avoid bias
- Try stale cache for all fetch errors in autoeq-importer, not just timeouts
Audio pipeline:
- Pass postProcessingQuality (preserves Dolby Atmos override) in api.js
- Persist custom band frequencies in equalizerSettings storage
- Restore custom frequencies on _loadSettings instead of regenerating defaults
- Export clamped preamp value in applyAutoEQBands text output
- Propagate filter type and Q values through equalizer import chain
- Update freqRange after importing custom filter frequencies
- Remove return in finally block that hid LOSSLESS fallback failures
Data consistency:
- Normalize artist IDs with String() in blockArtist/unblockArtist
Lint & code quality:
- Annotate empty catch blocks (Atmos codec probes)
- Remove unused catch parameters
Accessibility:
- Add aria-label and for attributes to all AutoEQ form controls
- Add role="status" aria-live="polite" to feedback spans
- Update filter type documentation to reflect shelf support
- Hide parametric-only sections by default to match active tab
UI:
- Move AutoEq button directly under graph
- Hide shared button in Parametric/Speaker modes
- Replace hardcoded white legend dot with theme-adaptive color-mix
- Add pointer-events:none and focus-within to profile delete button
