Audio
reactive.

A particle cloud shaped by the frequencies inside a song, built in TouchDesigner as sound becomes movement, density, and colour.

The idea

I used TouchDesigner to get the frequencies of a song and use them to manipulate a particle cloud. The sound is not just playing alongside the image; it becomes the force shaping it.

How it works

Audio analysis reads the song into frequency data. Math CHOPs remap and smooth those values, while Null CHOP references keep the network organised and send the changing numbers into the particle system.

What’s inside

  • Frequency analysis from the source audio
  • Math CHOP remapping and control ranges
  • Null CHOP references between the audio and visual network
  • Particle movement, scale, colour, and density driven by sound

Where it could go

A base for live music visuals, reactive installations, and performances where the image grows directly out of the sound.
