Voice changer for OBS — no routing setup.

OBS picks up the transformed voice from your existing mic. No virtual cable, no audio filter chain, no broken setup at the worst possible moment.

OBS + voice changer = usually a routing nightmare

Most voice changer tutorials for OBS read like a Linux audio guide from 2015: install VB-Audio Cable, route your mic into Cable Input, set Cable Output as OBS’s mic source, hope OBS doesn’t show “no signal”, repeat until something works.

When you’re trying to start a stream this is the last thing you want to debug.

VoxBooster doesn’t need any of that. OBS reads from your real microphone — VoxBooster sits between the mic and Windows audio, so OBS automatically gets the transformed voice without you touching its settings.

Works with what you already have

  • OBS Studio — yes
  • Streamlabs Desktop — yes
  • Twitch Studio — yes
  • XSplit — yes
  • YouTube Studio (browser stream) — yes
  • Restream.io / Switchboard Live — yes

If your streaming software can pick up your microphone, it can pick up VoxBooster.

Setup in 4 steps

  1. Install VoxBooster. 40 MB, runs on Windows 10/11. The trial starts automatically on first launch — no credit card.
  2. Pick a voice. Open VoxBooster, hit the Voice Clone tab, select one of the built-in personas. Or use Voice Effects for a Demon/Helium/Robot-style filter.
  3. Open OBS. Don’t change your audio settings. Your existing mic source is already correct.
  4. Hit “Start Streaming”. Talk. The voice that goes out is the transformed one.

That’s the whole flow. No “Add Filter → Audio Capture → Output Device” chain. No “you may need to restart OBS for changes to take effect” loop.

Real-time, low latency

Voice effects (filter-based) transform in ~5 ms. Voice Clone (neural) runs at ~500 ms by default, tunable down to 250 ms. On a stream that’s already adding 2-10 seconds of broadcast latency, neither is perceptible.

Hotkeys mid-stream

Bind any voice or sound to a hotkey and trigger it without leaving your scene:

  • Swap voices on the fly (Demon to Helium to your AI persona)
  • Fire soundboard samples (alerts, memes, stings)
  • Mute your real voice and let an AI persona TTS the announcement
  • Panic-disable the transformation if something glitches

All hotkeys are global — works whether OBS is focused or you’re tabbed into the game.

Doesn’t conflict with your existing audio chain

If you already use:

  • A noise suppressor (NVIDIA Broadcast, RTX Voice, Krisp) — works alongside, but VoxBooster’s built-in noise suppression usually beats them; disable the others to reduce double-processing.
  • A compressor / gate in OBS audio filters — leave them. They process the already-transformed output.
  • Stream Deck / Loupedeck — VoxBooster hotkeys are global keys, so any deck that fires a hotkey can trigger any action.

Privacy

Voice processing is 100% local. Nothing is sent to our servers. The Windows client has no audio upload path — you can verify by checking outbound connections in any firewall while a voice clone is running.
