+
+objective:
+- Add user controls for visualizer settings
+- Create settings panel for customization
+- Allow users to adjust visualizer parameters
+
+deliverables:
+- src/components/VisualizerSettings.tsx - Settings component
+- Updated src/components/Player.tsx - Settings panel integration
+- src/types/settings.ts - Visualizer settings type definition
+- src/stores/settings.ts - Settings state management
+
+steps:
+- Define visualizer settings types:
+  - Number of bars (resolution)
+  - Sensitivity (autosens toggle + manual value)
+  - Noise reduction level
+  - Frequency cutoffs (low/high)
+  - Bar width and spacing
+  - Color scheme options
+- Create VisualizerSettings component:
+  - Display current settings
+  - Allow adjusting each parameter
+  - Show real-time feedback
+  - Save settings to app store
+- Integrate with Player component:
+  - Add settings button
+  - Show settings panel when toggled
+  - Apply settings to RealtimeWaveform component
+- Update settings state management:
+  - Load saved settings from app store
+  - Save settings on change
+  - Provide default values
+- Create UI for settings:
+  - Keyboard shortcuts for quick adjustment
+  - Visual feedback for changes
+  - Help text for each setting
+- Add settings persistence
+- Create tests for settings component
+
+tests:
+- Unit: Test settings type definitions
+- Unit: Test settings state management
+- Unit: Test VisualizerSettings component
+- Integration: Test settings apply to visualization
+- Integration: Test settings persistence
+- Manual: Test all settings controls
+
+acceptance_criteria:
+- VisualizerSettings component renders correctly
+- All settings can be adjusted
+- Changes apply in real-time
+- Settings persist between sessions
+- Keyboard shortcuts work
+- Component handles invalid settings gracefully
+
+validation:
+- Run: `bun test` for unit tests
+- Run: `bun test` for integration tests
+- Manual: Test all settings
+- Manual: Test keyboard shortcuts
+- Manual: Test settings persistence
+
+notes:
+- Settings should have sensible defaults
+- Some settings may require visualizer re-initialization
+- Consider limiting certain settings to avoid performance issues
+- Add tooltips or help text for complex settings
+- Settings should be optional - users can start without them
+- Keep UI simple and intuitive
