BLENDER VISUALIZER

Audio-reactive Animation | R&D

Fig 1: Blender Visualizer (please wait for the beat to drop)

This vaporwave visualization of an unnamed and unreleased song by my pal, Ada Toydemir (Instagram @simulacrum_._), was made entirely in Blender; the bust was sculpted in another friend's likeness, with it and the sound levels beside it animated via geometry nodes.

Breakdown

Turning Blender into a visualizer first required writing a custom addon in Python, which: retrieves sound levels from Blender's built-in sequencer, filters the data into four, user-specified frequency bins, and stores the filtered data as keyframes tied to the scale of labeled objects in the scene -- one for each frequency bin, and a fifth for the unfiltered volume (Fig 2).

​

This process renders the sound data useable, as animations can be procedurally synced with the music by referencing the keyframed objects' respective scale values.
