A pack of custom nodes that enable audio reactivity within ComfyUI, allowing you to generate AI-driven animations that sync with music

What Does This Do?

  • Create Audio Reactive AI videos, enable controls over AI generations styles, content and composition with any audio
  • Simple: Just Drop one of our Workflows in ComfyUI and specify your audio and visuals input
  • Flexible: Works with existing ComfyUI AI tech and nodes (eg: IPAdapter, AnimateDiff, ControlNet, etc.)
