Swap Soul

How to set up Swap Soul with OBS, Zoom and Discord

Swap Soul runs in Chrome or Edge. To get your new face and voice into another app (Zoom, Meet, Signal, Discord, OBS…) you need two free tools on your computer: OBS Studio (turns the video into a webcam) and a virtual audio cable (turns the AI voice into a microphone). The Setup button in the studio checks each step for you.

How to set it up on a Windows PC

  1. 1
    Install VB-Cable (free): run the setup as administrator, then restart the PC.
  2. 2
    Install OBS Studio.
  3. 3
    Open the studio, click Setup → On this computer. Pick your real microphone, press Test (the bar should move), then press Send my AI voice to CABLE Input.
  4. 4
    Press Start swap, then the 📺 button to open the output window. In OBS: Sources → + → Window Capture → the output window → Start Virtual Camera.
  5. 5
    In your call app: Microphone = CABLE Output, Camera = OBS Virtual Camera, Speaker = your headphones.
  6. 6
    Press Start voice changer and talk. Use CABLE Input, not “CABLE In 16ch”.

Common setup questions

Do you record my video or voice?

No. Video goes from your browser to the face-swap engine and back; your voice passes through our server to the voice engine while you are live. Swap Soul does not store either, or what you say.

Why is there a delay on the voice?

The voice changer waits until you finish a sentence so it can speak it naturally (about half a second). Turn on Lip Sync in the voice settings so the video waits for the voice.

Can I use a photo of a celebrity or someone I know?

Only with that person’s clear permission. Read the Acceptable Use Policy.

What computer do I need?

Any recent Windows PC or Mac with Chrome or Edge and a decent connection (10 Mbps up/down). The AI runs in the cloud, so no special graphics card is needed.

When are credits used?

Only while the face swap or voice changer is running. Setting up, browsing voices and testing your mic are free.

Can I use it on my phone?

The studio needs a computer. Your phone can be the laptop side of Remote Studio (open /remote in Chrome or Safari).

What if something isn’t working?

The other person hears nothing

Your call app’s microphone must be CABLE Output (Windows) or BlackHole 2ch (Mac), and the studio’s Output Device the matching cable input. Run Setup — it checks this.

The mic meter doesn’t move

Setup → pick your real microphone → Test. Check the browser’s microphone permission (the camera icon in the address bar).

The cable isn’t listed

Install it as administrator and restart. Over Remote Desktop, set “Play sound: On the remote PC”.

OBS shows a black or frozen picture

Use Window Capture of the 📺 output window (not a Browser Source), and keep the swap running.

“Not enough credits”

A face swap needs at least half a minute of credit to start. Buy a pack from Credits & billing.

Payment sent but no credits

Credits arrive when the network confirms the payment. Keep the checkout page open; if it’s been more than an hour, contact support with the payment ID from your billing history.

Still stuck? Contact support — include what you see in the studio’s debug console (Ctrl+D).
