Afters: The Simulator

Afters: The Simulator is a browser music visualizer for electronic music, techno and DJ sets. Step into an immersive dance floor with anonymous dancers, shifting light and a choice of visual worlds.

Play a set in another browser tab, select Connect audio, then choose that tab and enable Share tab audio. Shared sound shapes the light, visuals and crowd energy. Use desktop Chrome or Edge for tab audio.

Choose a palette, adjust the response and walk through the room. Without shared audio, some visuals move on their own while others hold still. The room reacts to audio levels and frequency bands; it does not identify songs. Audio stays in your browser, without recording or uploading it.
