Cepheid Visualizer

Audio reactive visuals in Processing

Cepheid Visualizer is a Processing sketch combining two audio reactive modes. Mode 0 is a PBR scene with bloom and mini spheres that react to sound. Mode 1 is a lightweight black hole visualization with six audio-driven rays and a screen-space distortion shader.

Technical details

The sketch uses Processing with the sound library and several GLSL shaders. Heavy visual work is done in fragment shaders so CPU load is minimal. The black hole effect is a screen-space distortion that simulates lensing and a glowing accretion ring.
