Eo.S.
The music-optimized version — tuned for audio performance.
Glowsticks v2 03 is the music-optimized branch of the series, with energy response curves tuned for a wide range of genres. The geometric lattice through which the light rays travel has more angles than v2 02, creating more complex interference patterns when the audio has dense harmonic content.
Cleaner lines, surface work, and deliberate patterning. These are the presets that feel architectural rather than painterly.
Glowsticks, oscilloscopes, prisms, cubes, and hard edges.
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. Eo.S. - glowsticks v2 03 music maps those parameters into its own visual language.
