A ComfyUI node that generates animated dotted waveform visualizations from audio input with multiple animation styles.
- Six Animation Styles: Scrolling, breathing, radial, bars, wave, and spectrum
- FFT Spectrum Analysis: Real-time frequency domain visualization like music equalizers
- Teardrop Bars: Bell curve shape with sharp edges using exponential decay
- Audio Passthrough: Compatible with VideoHelperSuite Video Combine
- HD Output: Up to 1920x1920 resolution support
- Variable Opacity: Uniform, 3-level, 5-level, or 10-level opacity modes
- Enhanced Max Height: Up to 150% of image height for taller waveforms
- Preview Mode: Fast preview for testing settings without audio processing

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
- 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
- Audio Formats: All ComfyUI compatible audio formats
- Audio Compatibility: Automatic mono→stereo conversion for VideoHelperSuite
- Sample Rates: Works with 24kHz, and standard rates
- Output: RGB image sequences compatible with video nodes
- NEW: Added spectrum animation style with FFT frequency analysis
- NEW: Real-time frequency domain visualization (bass/mid/treble separation)
- NEW: Hanning window function for cleaner frequency analysis
- NEW: Automatic frequency band normalization for consistent visualization
- ENHANCED: Spectrum bars mirror top/bottom like other animation styles
- ENHANCED: All existing settings (size, spacing, opacity_mode) work with spectrum mode
- Added wave animation style with multiple layered sine patterns
- Increased max_height range to 150% (was 110%) for taller waveforms
- Fixed all preview modes to correctly display each animation style
- Improved tooltips and parameter organization
- Enhanced wave animation with proper audio responsiveness
- Four animation styles: scrolling, breathing, radial, and bars
- Bars mode with teardrop bell curve shape and 2x enhanced height response
- Audio passthrough compatibility with VideoHelperSuite Video Combine node
- Automatic mono→stereo conversion and float16→float32 for video integration
- Multiple opacity modes: uniform, 3_levels, 5_levels, 10_levels
- HD output support up to 1920x1920 resolution
- Full color customization with hex color support
- Preview mode for fast settings testing
- Sharp-edged teardrop shape using exponential decay mathematics
