About NVIDIA Broadcast

Using the power of AI, NVIDIA Broadcast can upgrade any room into a professional-grade home studio by enhancing standard webcams and microphones. Its advanced AI features, including microphone noise and room echo removal, virtual background, webcam auto frame, and video noise removal, improve the quality of your livestream significantly. The AI networks are powered by Tensor Cores, which are dedicated AI processors on NVIDIA RTX GPUs, enabling high-quality effects to be run in real-time.


Quick-Start Guide

NVIDIA Broadcast creates a virtual device on your Windows PC that applies AI effects to your microphone, speakers, or webcam, optimizing it in a variety of ways. You'll want to select this virtual device (called NVIDIA Broadcast) in your live streaming or video conferencing application.


  1. Download the App.
  2. Install the application. During installation, the application will download the necessary files for your system. The download size is about 400 MB, so make sure you are connected to the Internet.
  3. Restart your system.


  1. Set up NVIDIA Broadcast:

a. Open the NVIDIA Broadcast app.

b. Navigate to each device and select the input device at the top.

c. Select the effect you want to apply.

i. You may combine more than 1 effect if you wish.

ii. We recommend that you only turn on the effects you need to avoid consuming unnecessary GPU resources.

d. If needed, you can adjust the strength or settings of the effect with the sliders under it.

2. Review your Windows Sound Settings

a. Go to Windows Settings > System > Sound and make sure you have set your headset or speakers as the output device. You should not leave the NVIDIA Broadcast speakers as the default setting because you need to filter out all system sounds.

b. If you prefer, you can select the NVIDIA Broadcast microphone as the input device. This way, you do not need to configure it in each application. In this case, be sure to select the actual microphone in the NVIDIA Broadcast application.

3. Configure your live-streaming or video conferencing apps:

a. Open the app that you want to use

b. Go to Settings, then navigate to the Audio and Video sections

c. Select the NVIDIA Broadcast devices:

i. Microphone (NVIDIA Broadcast)

ii. Speaker (NVIDIA Broadcast)

iii. Camera (NVIDIA Broadcast)

Advanced Settings:

  • About Multi-Effects: From version 1.2 and above, you may combine AI effects per device. Running more than 1 effect will increase the GPU usage of the app.
    • To add a secondary effect just click on the Add Effect button.
    • To remove an effect, click on the effect name and scroll down to “x Remove this effect”.

  • Avoid issues with third party filters: Applications sometimes use effects similar to those in NVIDIA Broadcast, such as denoising. Applying the effect twice often causes the effect to not render correctly. We recommend disabling such effects in your application and driver.

  • Changing Resolution: If you want to adjust the camera resolution, you need to do it via NVIDIA Broadcast. In live/video conferencing applications, the default settings should be left in place or matched to the NVIDIA Broadcast settings. If you change the webcam resolution in NVIDIA Broadcast, you will need to reload the webcam in the app (i.e. close the app and open it again, or adjust the resolution if it is not set to "Auto").

  • If you connect/disconnect microphone/speakers often:If you switch between microphone and speaker often (i.e. plug and unplug often), you can select (default device) as input for NVIDIA Broadcast. This will automatically use any microphone/speaker detected by Windows as the new default device input, so you don't have to configure it every time.

  • Setting NVIDIA Broadcast as the default device in Windows Sound settings: In Windows, you can select NVIDIA Broadcast as the default microphone so that you don't have to change it in every application. . If you select this option, be sure to select the actual microphone in NVIDIA Broadcast. Do not do this for speakers, as you will then start filtering all audio from the device, such as video and music.

How To Test

NVIDIA Broadcast has a test feature embedded in the app:

To test your microphone, record your own audio in an environment with background noise. Now you can play the file and turn the effect on and off, or adjust the strength to see what changes the effect brings to the audio.

To test your speakers, we've provided some recordings that you can listen to with the effect on and off to compare what changes have been made. You can also adjust the strength of the effect.

To test the webcam, simply use the preview window.
