Making something beautiful with audio and video

I love all the algorithmic audiovisual stuff agents can make. I often need to generate visuals, audio and video for a pet project, and that gives me so many interesting ideas that I can't keep quiet about them.

Last night I decided to give Claude complete freedom to generate a few audio visualizers for me. I liked them so much that I spent hours playing with them. Take a look:

It's an audio wave visualizer with a Windows Media Player 2005 kind of feel. It quickly analyzes a selected track and starts moving to the beat. There are plenty of controls to tweak the wave in real time, so you can find the look you like best. That's how I picked one I'll use in my own videos.

FFmpeg doesn't even take catastrophically long to render it on the GPU. While working on it, I also sped up my overall rendering process several times over. Typical vibe coding, with lots of fun along the way.
