I’ve been playing with TouchDesigner recently, exploring ways to connect music and visuals: using the mid and high frequencies of a background track to drive dynamic changes in visuals.
I started by using the Audio Spectrum CHOP to split the audio into different frequency bands. Then I extracted the midand high values as control parameters to manipulate certain layers in the scene—like scaling, position shifting, and even shader-based distortion. The result is a visual that “dances” with the music in real time.
One of my favorite additions is a little boom glow effect—when the high frequencies suddenly spike, it triggers a burst of glowing light in the visuals, like a tiny explosion. It adds a sense of rhythm and punch to the whole piece, emphasizing certain beats and creating a more immersive, concert-like feel.
Next step, I’m thinking about incorporating the low frequencies to control more grounded movements—like global structure wobble or a soft, breathing motion in the background.
