How to Lip-Sync with Audio on Windows or MacOS

You can use audio playing on Windows or MacOS (YouTube, AI Voice Synthesis, Translators, Music, etc.) as the microphone input for lip-sync.

Windows Setup

1: Install the Virtual Cable

1. Download the VBCABLE_Driver_Pack (.zip) from the VB-CABLE Virtual Audio Device official website.
2. Extract the ZIP file, right-click the setup file (VBCABLE_Setup_x64.exe) and select Run as administrator, then restart your computer after installation.

2: Route your PC Audio

1. Press Windows Key + R, type mmsys.cpl in the Run dialog, and press Enter.
2. Go to the Playback tab, right-click CABLE Input, and select Set as Default Device.

3: Connect to the App

1. In Webcam Motion Receiver, open Facial Expressions Settings and select Microphone under LIP SYNC MODE at the bottom.
2. In the Select Mic dropdown menu, choose CABLE Output (VB-Audio Virtual). (See Figure 1)

Play a YouTube video or music. If the meter to the right of Minimum Volume is moving, the lip-sync will be reflected on the avatar. If the minimum volume meter is moving but the lip-sync is not reflected, try changing the Voice Type (Low pitch / High pitch) setting.

4. In the "Playback through this device" dropdown, select your normal physical headphones or speakers, then click OK.
