US Patent 12119026 Multimedia music creation using visual input

A system for creating music using visual input. The system detects events and metrics (e.g., objects, gestures, etc.) in user input (e.g., video, audio, music data, touch, motion, etc.) and generates music and visual effects that are synchronized with the detected events and correspond to the detected metrics. To generate the music, the system selects parts from a library of stored music data and assigns each part to the detected events and metrics (e.g., using heuristics to match musical attributes to visual attributes in the user input). To generate the visual effects, the system applies rules (e.g., that map musical attributes to visual attributes) to translate the generated music data to visual effects. Because the visual effects are generated using music data that is generated using the detected events/metrics, both the generated music and the visual effects are synchronized with—and correspond to—the user input.
