Important/Additional Notes:

This plugin operates entirely offline using Unreal Engine's built-in audio envelope analysis system.

To use the system, the user must connect the LipSync value to the character's facial animation or morph targets inside your AnimBP.

This setup is required for MetaHuman, UE4, UE5, and custom characters.

A complete step-by-step configuration guide is included in the documentation and tutorial video.
