Circle loops project, looking for ideas

Hello there, I’m making a project for my University: it asks to select a song from File Explorer and then creates loop circles according to the sound. This is my actual project: https://drive.google.com/drive/folders/1XKUREZb9m3d6vCr0ZbWbvpszReyg4Ht4?usp=sharing
This a video example: https://drive.google.com/file/d/1-NEDbbMZ-sBub0sqtjtVUyMKJOUG2RFx/view?usp=sharing
Any way to add shaders or particles in a smart way? Thanks in advance, any help is appreciated!
