Below is an artefact video of a project I did for a R&D unit. The whole system is procedurally generated by the music input using Unreal Engines Niagara particle system but also the lights, transforms, objects, and camera movement are also controlled by the music.
I used it the class 'Clair De Lune' by Debussy to create these accompanying visuals which slowly ascend into the sky as it plays.
