Visual Systems That Respond to Sound
Audio Reactive Systems explores microphone-driven GLSL experiments where bass, mids, highs, and signal level shape realtime procedural visuals.
Audio Nebula Drive
Click the audio control on the shader to enable microphone input. The nebula reacts to overall level, bass movement, midrange motion, and high-frequency detail.

This realtime shader may be too intensive for your current device or browser.
Signal Driven Visuals
These shaders use simple audio analysis uniforms to turn incoming sound into motion, brightness, distortion, rhythm, and color response.
Audio Pulse Core
A compact audio-reactive test system that uses bass, mids, highs, and overall level to drive rings, grids, and central glow.

Feedback Nebula Smear
A recursive feedback shader where audio input influences spiral memory, glow persistence, and evolving temporal trails.

Four Signals for Realtime Response
The BLOKS Shader Viewer currently exposes overall level, bass, midrange, and high-frequency energy as realtime uniforms for GLSL experiments.
