Free Soundboard for OBS

Get the Facecam soundboard into OBS: on its own as a browser source, or mixed with your mic through VDO.Ninja. Free, no sign-up.

Soundboard: play sounds into your mic

Your browser will ask for microphone access when you click.

Set it up in OBS

  1. Decide what OBS should receive

    Only the sounds? Add the soundboard page itself as a Browser source, which needs no extension. Your voice and the sounds as one mixed source, with voice ducking? Follow the next steps.

  2. Send the board to the extension

    In Chrome, open the Facecam soundboard and click Use these sounds in calls.

  3. Push the mic from VDO.Ninja

    Go to vdo.ninja in Chrome and choose Add your Camera to OBS. Allow the microphone, select “Facecam Virtual Mic” as the audio source, and click Start.

  4. Add the view link to OBS

    Copy the view link VDO.Ninja shows. In OBS add a Browser source, paste the link, and turn on Control audio via OBS so it gets its own fader in the mixer.

  5. Mute your normal mic in OBS

    Your voice now arrives inside the browser source. Mute the old Mic/Aux input, or viewers hear you twice.

Three ways into OBS

RouteWhat OBS getsExtensionGood for
Soundboard page as a Browser sourceSounds onlyNot neededSolo streams; play with Interact
VDO.Ninja view link as a Browser sourceYour voice and sounds, mixedNeededVoice ducking, voice changer plus sounds
Capture Chrome's audioWhatever the Chrome window playsNot neededQuick tests

For the third route, OBS has Application Audio Capture on Windows 10 (version 2004 or later) and Windows 11, and macOS Screen Capture can take a window with its audio on macOS 13 or newer. The soundboard page plays each clip out loud in Chrome, which is the audio these sources pick up.

More about OBS

Why not just pick the mic in OBS

OBS reads microphones from your operating system. Facecam adds its mic inside Chrome's pages only, with no audio driver installed on your computer. OBS's Browser source can't help directly either: it's built on the Chromium Embedded Framework, a separate browser without your extensions. VDO.Ninja bridges the two, because its sending page is an ordinary Chrome tab.

Questions

Does this work in Streamlabs Desktop?

Streamlabs Desktop has Browser sources too, so the same link should work there. These steps were written for OBS Studio.

Can I use the voice changer on the same link?

Yes. The voice changer and the soundboard share the Facecam mic, so the VDO.Ninja source carries both.

Is VDO.Ninja part of Facecam?

No. It's a separate free tool that sends a camera or mic from a browser tab to OBS.

Which route has the least delay?

The soundboard page as a Browser source: the sounds are produced inside OBS itself.
