Installing Nvidia Broadcast
Broadcast runs on any RTX 20-series or newer GPU. Download it from the Nvidia site or through the NVIDIA App, install it, and reboot. On first launch it creates virtual microphone, speaker, and camera devices that you then select inside apps like OBS, Discord, Zoom, or Teams.
Configuring AI Noise Removal
The headline feature is AI noise removal. Set your physical microphone as the input, enable Noise Removal, and slide the intensity to taste; around 70-90% eliminates keyboard clatter and fans while keeping your voice natural. Apply the same effect to your speakers to strip noise from other participants on a call.
Setting Up Virtual Background and Auto Frame
Under the camera tab, choose Background Removal, Blur, or Replacement. Blur is the most reliable without a green screen, while Replacement works best with even lighting. Enable Auto Frame to have the AI pan and zoom to keep you centered as you move.
Pairing Broadcast With Capture Hardware
Broadcast shines alongside good capture gear. A card like the AVerMedia 4K HDMI Capture Card lets you bring in a dedicated camera or console feed, while an audio interface such as the RØDE X Streamer X gives your microphone a clean signal for Broadcast to enhance.
Integrating With OBS and Chat Apps
In OBS, add the Camera (NVIDIA Broadcast) source and select the NVIDIA Broadcast microphone as your audio input. In Discord, Zoom, or Teams, simply pick the Broadcast virtual devices in settings. The effects then apply everywhere automatically.
Tips
- Keep noise removal between 70-90% to avoid a robotic, over-processed voice
- Use background blur instead of replacement if your lighting is uneven
- Enable Auto Frame for handheld or standing presentations, disable it for static seated calls
- Close other GPU-heavy apps if you notice a frame-rate dip while gaming and streaming

Does Broadcast hurt gaming performance?
The effects use some GPU resources, but on modern RTX cards the impact while gaming is usually a few frames at most. Lowering effect intensity reduces the load.
Can I use Broadcast with any microphone or camera?
Yes. Broadcast processes the input from any microphone or webcam, and it pairs especially well with capture cards and audio interfaces for higher-quality source signals.
Is a green screen needed for background replacement?
No. Broadcast removes or replaces backgrounds using AI without a green screen, though even lighting improves the result significantly.
