Open Source TypeScript Audio Analysis Software

Astrofox is a free, open-source motion graphics application that transforms audio into animated visual content. It allows musicians, video creators, and artists to produce audio-reactive graphics for music videos and visual presentations. Users can combine visual elements, text, and audio-driven effects to create compositions that respond to sound. Projects can be saved locally in the native AFX format and reopened for further editing. The application runs in a browser or as an Electron desktop program. Its desktop edition supports offline operation and can use fonts installed on the computer. Video rendering uses browser recording capabilities or FFmpeg, depending on the platform. An optional MCP server allows compatible external tools to automate supported editing operations.
