Stands out in the Blender extensions library for its two-in-one approach: generate a ready-made cube visualizer, or map audio onto objects you already have. Version 1.2.0 adds Blender 5.0 compatibility.
Simple Audio Visualizer is a Blender add-on from Polyfjord for turning an audio file into animation. It works in two ways: it can generate a set of animated cubes tied to the audio spectrum, or it can animate objects you select yourself. Both modes run from a panel in the Graph Editor sidebar.
When generating cubes, you point the add-on at an audio file and can set the number of cubes, adjust an intensity multiplier, and enable Mirror Mode. The cubes change height depending on the volume in their frequency sector, with sectors chosen along an exponential frequency curve. To drive your own objects, select them in the viewport, choose the transform channels (Location, Rotation, Scale) and axes to affect, and the audio spectrum is distributed across the objects sorted alphabetically. An Additive mode layers the animation on top of existing keyframes.
The add-on builds on a script originally created by GitHub user soerenmetje. Version 1.2.0 is a compatibility and stability release for Blender 5.0 that updates the animation baking internals while keeping the workflow and UI the same. It is released under the GNU General Public License v3.0 or later.
Simple Audio Visualizer is best for blender users who want to drive animation from an audio file, either as generated cubes or by animating their own objects.
Simple Audio Visualizer is completely free to download and use.
Simple Audio Visualizer is compatible with Blender 4.2 LTS and newer. Version 1.2.0 is a compatibility and stability release specifically for Blender 5.0, updating the animation baking internals to match Blender's newer animation data model while keeping the workflow and UI unchanged. That means the add-on runs on both the 4.2 LTS line and the 5.0 release. For the current list of supported versions, check the developer's page.
Simple Audio Visualizer lives in the Graph Editor sidebar, under a panel named "Simple Audio Visualizer". As a Blender extension it can be added by dragging and dropping the add-on into Blender, or by downloading it and installing from disk. Once it is enabled, open the Graph Editor, find the panel in the sidebar, and use it to generate a cube visualizer or animate selected objects. The panel is where you choose the audio file and set the animation options.
Simple Audio Visualizer is listed as free here in the catalog, and it is distributed under the GNU General Public License v3.0 or later. For current licensing terms and any conditions, refer to the developer's page. The license also means the code is openly available, and the add-on itself builds on a script originally created by GitHub user soerenmetje. If you need to confirm how you can use or modify it, the GPL v3.0-or-later terms apply.
Simple Audio Visualizer can animate objects you select yourself, not just generated cubes. In the 3D viewport, select the object or objects you want, choose an audio file, and set the intensity multiplier. Then pick the transform channels (Location, Rotation, Scale) and axes (X, Y, Z) to animate, and click Visualize Selected Objects. The audio spectrum is distributed across your selected objects, sorted alphabetically, and animated to your settings. An Additive mode adds the animation on top of existing keyframes rather than replacing them.
