Sound Nodes Lite is an audio visualization tool that extracts information from music files to drive animations within the Geometry Nodes editor. It analyzes audio formats including MP3, WAV, FLAC, and OGG, storing the extracted data as keyframes to maintain playback performance in the viewport.

This free version provides access to loudness and spectrogram data, allowing users to visualize specific frequencies and volume levels in their node setups. The addon also includes three demo project files to help users get started with building audio-reactive geometry.
