AI Analysis

●●●BangerRabbit HoleWizardry

Milkdrop running in the browser via WebGPU is pure nostalgia fuel.

Strengths

•Porting a complex C++ visualizer to WASM+WebGPU is a serious technical feat.
•Real-time mic input reaction works surprisingly well for a browser demo.

Weaknesses

•WebGPU support is still spotty on many browsers and devices.
•Mobile experience is limited by mic/speaker hardware constraints.

Post Description

Went on a side quest while working on an unrelated project. Milkdrop is an audio visualizer that was popular among many Winamp users, and I asked Claude to build a WASM+WebGPU port, and /mostly/ walked away with some guidance peppered throughout the multi-day session.

If you're on a laptop/desktop, it'll ask for mic access and react to whatever you're playing (or surrounding sounds), if you're on mobile you may need to speak into your phone or point it at some music since the mic disables its speaker. Enjoy!
