Pulse Rings — 3D Audio Visualiser
3D audio visualiser, in one HTML file. Beat / mic / your track.
3D audio visualiser, built entirely in code: one self-contained HTML file with no images, no 3D models and no build step. Under the hood: Three.js, audio-reactive InstancedMesh (500 bars), DataTexture spectrum, Web Audio API. What a visitor can do: built-in synthetic beat plays by default, ● MIC uses your microphone, ▲ TRACK plays any audio file, drag to orbit, 4 presets incl. a rainbow spectrum. Best for: Music, podcasts, DJs, events, voice products. Three.js loads from a CDN through an import map, so there is still nothing to install. Every colour, count and speed sits in one CONFIG block, presets switch live from a glass dock, and ?embed strips the interface for a clean iframe or hero background.
How to run this
Nothing to install and nothing to configure. Works in any modern browser on Windows, macOS and Linux.
- Built with
- Single HTML file
- Requires
- A modern browser
- 1. Unzip the download.
- 2. Double-click index.html. It opens in your browser and runs. To serve it instead (the microphone and some browsers want a server), run
npx serve .in the folder and openhttp://localhost:3000.
Note — Three.js loads from the jsDelivr CDN through an import map, so the first load needs an internet connection. The microphone mode needs https or localhost, which is what npx serve gives you. Add ?embed to hide the interface for an iframe or hero background, and ?preset=N to start on a colour preset.
