🎨 Advanced Features
<details> <summary><b>🌈 Gradient System</b> - Multi-color gradients on any animation</summary>Multi-Color Gradient Support
Create stunning multi-color gradient effects that work with ALL animation styles:
-
Enable: Toggle "🌈 Gradient Mode" in the node
-
Edit: Click "✨ Edit Gradient" to open the visual gradient editor
-
Gradient Stops: Add up to 10 color stops with custom positions (0.0 to 1.0)

Gradient Presets
6 built-in gradient presets for quick styling:
- Cyber: Electric blue to hot pink
- Fire: Yellow to deep red
- Ocean: Cyan to deep blue
- Sunset: Orange to purple
- Matrix: Bright to dark green
- Rainbow: Full color spectrum
Visual Color Picker
Modern color picker interface replaces standard text input:
- Click "🎨 Pick Dot Color" or "🎨 Pick BG Color" to open picker
- 8 Preset Palettes: Neon, Pastel, Synthwave, Monochrome, Fire, Ocean, Forest, Sunset
- Dark Theme: Modern gradient UI with centered modal
- Quick Selection: Click any preset color for instant application
- Hex Display: Shows hex codes for each color
Amplitude Boost
Fine-tune waveform intensity beyond standard max_height:
- Enable: Toggle "⚙️ Advanced Mode" in the node
- Range: 0.5x to 5.0x multiplier (default: 1.5x when enabled)
- Effect: Multiplies the max_height parameter for extra-tall waveforms
- Default Behavior: When Advanced Mode is OFF, amplitude_boost = 1.0 (no boost)
- Use Cases:
- Boost subtle audio signals (3.0x-5.0x)
- Reduce overwhelming waveforms (0.5x-0.9x)
- Perfect combination with max_height for ultimate control
Interactive Help System
Every parameter includes detailed tooltip explanations:
- Hover: Move mouse over any parameter label
- Instant Help: Tooltip appears with description and tips
- Context-Aware: Explains parameter effects for each animation style
- Examples Included: Most tooltips show example values and use cases

🎨 Animation Styles
Scrolling: Waveform scrolls left-to-right following audio timeline with continuous center line
Breathing: All dots pulse together with audio amplitude uniformly
Radial: Concentric rings expand from center creating ripple effects
Bars: Vertical frequency bars with teardrop bell curve shape and 2x enhanced height response
Wave: Multiple layered sine wave patterns that morph with audio intensity
Spectrum: FFT frequency analysis displaying bass (left) to treble (right) like music equalizers
Circular: Dots arranged in a circle with radius that expands and contracts with audio amplitude
🎭 Opacity Modes
- uniform: All elements same brightness (fastest)
- 3_levels: 0%, 50%, 100% opacity steps
- 5_levels: Progressive 0%, 25%, 50%, 75%, 100% opacity
- 10_levels: Smoothest gradients with 10 opacity levels
🔧 Technical Notes
- Audio Formats: All ComfyUI compatible audio formats
- Audio Compatibility: Automatic mono→stereo conversion for VideoHelperSuite
