Simple Audio Visualizer

Changelog

Version 1.2.0

This update is a compatibility and stability release for Blender 5.0. It updates the animation baking internals to match Blender’s newer Action Slot / Channelbag system, while keeping the workflow and UI the same.

• Blender 5.0 Compatibility: Updated the audio baking pipeline to work with Blender 5.0’s new animation data model (fixes the 'Action' object has no attribute 'fcurves' error).
• Fix: “Create Visualizer” no longer fails in Blender 5.0 when generating and baking new cube objects.
• Improvement: More robust animation setup — automatically ensures the object has valid animation data/action/slot before baking.
• Improvement: Safer Graph Editor context handling for the sound-to-keys bake, reducing failures when the operator is run from different UI states.

Changelog

Version 1.1.0

This update is a major overhaul, adding the ability to animate existing objects and providing significantly more control over the final effect. The goal of this extension is still to be a simple way to create audio visualizers in Blender.

• New Feature: Animate Selected Objects: You can now apply audio-driven animation to any object(s) you have selected, not just newly created cubes. The frequency spectrum is automatically distributed across the selection.
• New Feature: Full Transform Control: Choose exactly which transform properties (Location, Rotation, Scale) and which axes (X, Y, Z) are animated by the audio.
• New Feature: Intensity Multiplier: A simple slider to globally increase or decrease the strength of the visualizer effect.
• New Feature: Additive Mode: A new option that adds the audio animation on top of any existing animation, instead of replacing it. This is especially useful for creating continuous rotation effects.
• UI Overhaul: The addon panel has been improved with new informative tooltips.

Changelog

Simple Audio Visualizer Initial Release Version 1.0.0

Key Features:

Generate Audio Spectrum Visualization: Creates animated cubes that represent the frequency spectrum of a selected audio file within the Graph Editor workspace.

Adjustable Number of Columns: Customize the number of visual elements (columns) to balance between detail and performance. Higher values provide a more detailed visualization but may increase calculation time.

Mirror Mode Option: Enable mirror mode to offset the origins of the cubes, creating a symmetrical and dynamic visual effect.
