Audio Motion System is a native Unreal Engine C++ plugin for building audio-driven motion directly inside the Editor and at runtime.

Instead of manually creating complex Blueprint networks or relying on external applications, Audio Motion System provides a focused workspace where audio, Rig mapping, motion data and runtime output are connected through one consistent workflow.

Use Dialogue Mode to generate responsive motion from voice audio. Build deterministic Choreography from music using Motion Vocabulary and Style Books. Convert dialogue into a reusable Dialogue Curve. Combine real Animation Sequences with dialogue using the Animation Mixer. Drive scalar material parameters with audio through the lightweight Material Pulse system.

The plugin is designed around a simple principle:

Audio → Analysis → Motion → Preview → Runtime or Bake

Everything stays inside Unreal Engine.

Key Features

• Dialogue Mode — creates responsive audio-driven motion from voice sources.

• Procedural Choreography — generates deterministic motion timelines from music.

• Motion Vocabulary — reusable motion data that can be expanded independently from the plugin code.

• Style Books — define how available Motion Units are selected and combined for different motion styles.

• Rig Mapping — automatic presets for common UE-style rigs plus full Custom Mapping support.

• Dialogue Curve — converts voice response into a compact reusable scalar curve.

• Animation Mixer — combines dialogue with existing Animation Sequences, including retargeting workflows.

• Background Music support — dialogue and music can operate independently or together.

• Runtime Components — install and control Audio Motion directly on Actors.

• Blueprint API — ready-to-use connection functions for clips, music, dialogue, choreography and material response.

• C++ API — public runtime classes and components for custom integrations.

• Preview inside the AMS workspace before modifying your project.

• Bake to Animation Sequence for reusable Unreal animation assets.

• Deterministic generation — the same source and configuration produce repeatable results.

• Trajectory modes for generated Choreography.

• Material Pulse for audio-driven scalar material parameters.

• No cloud processing.

• No external executable.

• No subscription or online service required.

• No third-party runtime libraries.

Audio Motion System is useful for characters, stylized performers, creatures, props, mechanical rigs, interactive objects, cinematic scenes, music visualization and any Unreal project where sound should become motion.
