Resonant Chamber

Animusic is an American company specializing in the 3D visualization of MIDI-based music. Founded by Wayne Lytle, it is incorporated in New York and has offices in Texas and California. The initial name of the company was Visual Music, changed to Animusic in 1995.

Unlike many other music visualizations, the music drives the animation. While other productions might animate figures or characters to the music, the animated models in Animusic are created first, and are then programmed to follow what the music “tells them” to. Many of the instruments appear to be robotic or play themselves using curious methods to produce and visualize the original compositions. The animations typically feature dramatically-lit rooms or landscapes.
