Audio Lip-Sync Pro

Audio Lip-Sync Pro for Blender

Audio Lip-Sync Pro is a Blender add-on that generates lip-sync animation from audio clips. Its workflow starts with an audio file placed in Blender's video sequencer and produces ARKit blendshape keyframes for a compatible rigged mesh.

The add-on is designed for local use: processing takes place on the user's computer and does not require an account, subscription, or network access. It supports multilingual audio, with strongest performance stated for English and Mandarin Chinese. Blender 4.5 or later and a mesh rigged with ARKit blendshapes are required.

Features

Audio-driven workflow

Place an audio clip in Blender's video sequencer as the input for the lip-sync generation workflow.

ARKit keyframe generation

Create ARKit blendshape keyframes for a mesh that has been rigged with the required facial blendshapes.

Multilingual audio support

Process audio in multiple languages, with the strongest stated performance in English and Mandarin Chinese.

Local processing

Run processing locally without an account, subscription, or network access.

Unlimited full-version clips

Use the full version with no stated audio clip length limit, rather than the free version's five-second limit.

Use cases

  • Character dialogue animation

    Place recorded dialogue into Blender and generate facial animation data for a character mesh with ARKit blendshapes.

  • Offline or privacy-sensitive work

    Use local processing when working with audio that should remain on the production computer rather than being sent to an online service.

  • Short-clip prototyping

    Create lip-sync tests from short clips with the free version before deciding whether the full version's unlimited clip length is needed.

  • English and Mandarin workflows

    Prepare facial animation from English or Mandarin Chinese voice recordings, the languages identified as having the strongest performance.
