00 What it is

MILKDROP, REBORN

MilkDrop was released by Ryan Geiss in 2001 and became one of the most celebrated music visualisers ever made — a system where mathematical shader code produced flowing, organic, beat-reactive visuals in real time. SPECTRAFORGE brings that engine into the browser, adds a 148,000-preset library, deep beat detection, and an optional local AI layer that replaces random preset cycling with intelligent selection.

It runs entirely in-browser using Butterchurn — Jordan Berg's WebGL2 port of the MilkDrop engine — with no install, no cloud dependency, and no data leaving your machine.

▶ The standalone HTML visualiser runs directly in your browser — no backend, no install. Drop in an audio file or connect to system audio. The AI conductor and full 148k preset library require the optional backend services.

01 Core features

◈

BUTTERCHURN CORE

Full MilkDrop 2 compatibility. Every classic .milk preset runs natively — thousands of community-made shaders from two decades of creative work, rendered at 60fps in the browser.

♫

BEAT-LOCKED SYSTEM

Spectral flux onset detection, BPM estimation, and energy-band analysis feed directly into the shader uniforms. Every bass hit, transient, and frequency shift warps the visual in real time.

◆

AI CONDUCTOR

Optional local AI layer connects via Ollama. Reads audio features, classifies musical mood, and selects presets from the library intelligently — replacing random cycling with context-aware transitions.

▣

PERSISTENT LIBRARY

148,000 community presets indexed and stored locally via OPFS. Lazy streaming means the full library is navigable without loading everything into memory. Custom presets save between sessions.

⬡

BROWSER-NATIVE

No install. No account. No cloud. Runs on any modern browser with WebGL2 support. All AI processing is local — nothing leaves the machine.

◉

OPTIONAL BACKEND

Standalone operation works out of the box. Connecting the optional backend services unlocks the full AI preset pool, session analysis, and real-time musical intelligence.
