Umbra Shaders
Music visualizer. Milkdrop presets. Raw WebGL shaders. Pure vibe.
Fullscreen music shader visualizer with six custom WebGL shaders and classic Milkdrop preset rendering. Drop an audio file, use your mic, or let the ambient motion flow. Full controls, mini mode, keyboard shortcuts — built for pure immersion.
Open Umbra and it immediately fills your screen with motion. Six custom WebGL shaders and hundreds of Milkdrop presets react to whatever audio you give them — or drift on their own if you prefer silence.
Drop any audio file onto the canvas, switch to microphone input, or let the ambient motion carry the visuals. Three-band reactivity controls let you tune how bass, mids, and treble drive the shader parameters. Dial sensitivity from zero to double intensity.
Press M to collapse the panel into a minimal floating bar. Press F for true fullscreen. Use the arrow keys to cycle shaders, Space to play or pause, and Up/Down for volume. Every setting persists across sessions.
We built Umbra because every great game portfolio needs a place to just vibe. Milkdrop presets are a cultural artifact of digital music — thousands of community-made artworks that deserve a modern, accessible home. We paired them with six original raw-WebGL shaders tuned for smooth, meditative motion rather than seizure-inducing strobe. The result is a browser-native visualizer that loads instantly, needs no account, and works with any audio source you throw at it. Drop a track, hide the UI, and watch the void.
