cope
A shimmering ocean of pixels that swells with every bar.
Digital sea maps your audio's low-frequency envelope to wave height and the spectral centroid to surface shimmer. The result is something that feels genuinely oceanic — not in the screensaver sense but in the sense that the surface has memory, drag, and weather. Best experienced with ambient or downtempo.
Slow-burn visualizations with meditative symmetry, pulse, and repetition. Ideal when you want the room to sink into a groove instead of explode.
Mesmeric loops, kaleidoscopes, mandalas, and trance-state motion.
Upload any audio
Drag in a local file, connect a mic, stream a radio URL, or use one of the included sample tracks.
Real-time analysis
The Web Audio API analyses frequency content, amplitude, and transients at up to 60 fps, all without leaving your tab.
Shader renders the result
Butterchurn translates that data into GLSL shader parameters. cope - digital sea maps those parameters into its own visual language.
