Create An Audio Visualizer With Blender

CGMatter runs through how to create an audio visualizer with Blender, where objects auto-react to sound.

How would you like your music to be live onstage with the visuals of every note and sound? CGMatter has made it possible! In a record pace, they cover creating an audio visualizer (of sorts) using Blender. The system will raise and lower an arrayo f objects automatically triggered by volume so there’s no need for light cues or anything else complicated; just dance along as we all create our own chaos-the best kind out there right?!

Parenting and Deforming.

The tutorial uses a plane that has another object parented to it. Then instancing this “child” on the vertices of your original mesh and altering its scale will set up an array for audio visualization purposes, without having to do any extra work! A key benefit is being able pass down animation from one part of our system (the Plane) into other aspects too – like how we did with what happened here when you played around Animating Materials in 3D Printing Studio 2 months ago…

Animating the Plane.

Animating the plane to have its height change depending on which of the array objects it flies over is really simple with F-Curves. The sound will be automatically baked into each frame so that no two animations are alike!

Another Method That Uses Animation Nodes.

Sound Falloff Node is a very useful tool in terms of audio visualization. It can be used for generating an animation where the sound falls off based on how fast it’s going, and also takes into account which objects have been assigned values by their frequency (which may or may not change).
