It's a bit of a retro project but I've always wanted to have a go at doing spectral analysis of audio and never got around to it before now.
So, I built an MVP a few days ago in JS and using the Web Audio API - See note: https://scrapbook.mikehiggins.me.uk/?note=8a146bcf-50cb-4e8d-b391-a2d393ad3d21 , saved the code as a text file and then passed it over to Lovable.
After a bit of playing there I saved to Github and then connected to my IDE (AntiGravity) and to Netlify and worked on finessing everything for a few hours.
I like the results. As I say, it's a bit retro.

NB - There are two tracks automatically loaded allthough a user their upload own music files if they want. The tracks are written with Suno though the lyrics were not. In my experience, when writing with Suno, the lyrics need to be created seperately.
