NVIDIA Broadcast transforms any room into a home studio, upgrading standard webcams and microphones into premium, smart devices through the power of AI. Improve the video and audio quality of your livestream through AI capabilities such as microphone noise and room echo removal, virtual background, auto frame, and video noise removal. With dedicated AI processors called Tensor Cores on NVIDIA RTX GPUs, the AI networks are able to run high-quality effects in real-time.

NVIDIA Broadcast creates virtual devices on your Windows PC that take your microphone, speaker or webcam output and apply an AI effect to it, enhancing them in different ways. You want to select this virtual device (called NVIDIA Broadcast) in your live streaming or video conferencing apps.

1. Download the App.
2. Install it. During the installation, the app will download the necessary files for your system. The download requires ~3GB of additional storage so make sure you have good connectivity and enough storage space.

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.

iii. To check GPU usage for the effects you’ve enabled, enable the GPU Utilization indicator in “settings”.

d. For some effects you can adjust the settings of the effect with the sliders or options under it

2. Review your Windows Sound Settings

a. Go to Windows Settings > System > Sound and make sure your headset or speakers are set as the Output device. You don’t want NVIDIA Broadcast Speakers as default, as you would filter out all system sounds.

b. You may select the NVIDIA Broadcast Microphone as input. This way you don’t need to configure it per app. In this case, make sure you select your actual microphone in the NVIDIA Broadcast app.

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)

You are good to go!

• About Multi-Effects: You may combine AI effects per device.
  • Running more than one effect will increase the GPU usage of the app.
  • Not all effects can be combined. For example, Studio Voice cannot be combined with microphone background noise reduction.
• Avoid issues with third party filters: Applications can sometimes apply effects, such as noise cancelling, similar to those in NVIDIA Broadcast. Applying an effect twice will often result in the effect not working correctly. We recommend disabling such effects in your app and drivers.
• Changing Resolution. If you wish to adjust the camera resolution you need to do so with NVIDIA Broadcast. In your streaming/video conferencing app you should leave settings as default, or match your NVIDIA Broadcast settings. If you change the resolution of your webcam in NVIDIA Broadcast, you will need to reload the camera in your app (i.e. turn it off and on, and adjust the resolution if it’s not set to Auto).
• If you connect/disconnect microphone/speakers often: If you change your microphone/speakers often (i.e you plug and unplug them), you can select (Default device) as your inputs in NVIDIA Broadcast. This will automatically use any microphone/speaker that Windows detects as the new default as inputs, so you don’t have to keep configuring them every time.
• Setting NVIDIA Broadcast as the default device in Windows Sound settings: NVIDIA Broadcast can be selected as your default Microphone in Windows so that you don’t have to change it in every application. If you opt to do this, make sure that in NVIDIA Broadcast you select your actual microphone. Do not do this for Speakers, as you would start filtering all audio coming through your device, such as videos and music.
• Wide display mode: NVIDIA Broadcast now supports two sizes - a vertically oriented display, ideal for users who want an app with a small footprint for easy access, or a wider display mode for easier navigation and a larger video previews.
  
  • To expand or collapse the app view, click on the  expand/contract button on the top windows bar.

NVIDIA Broadcast has a test feature embedded in the app:

• To test your microphone, record yourself speaking with a background noise. You can now play the file and turn the effect on and off, or adjust the strength, to see how the effect changes the audio.
• To test your speakers, we have included several recordings that you can listen to while turning on and off the effect to see the change. You can also adjust the strength of the effect.
• To test your webcam, just use the preview window.
  • The preview window has a new “before/after” feature.  This lets you compare the raw camera output with NVIDIA Broadcast output with AI effects applied.  To enable, click on the side by side icon in the camera preview window

• Note:  Make sure you disable this feature before broadcasting or joining video calls, or your audience will also see the side by side video.

NVIDIA Broadcast Studio Voice, Virtual Key Light, and Video Noise Removal are currently in beta. Plus, version two of the app brought in an new user interface for the application. Please share your feedback to help us make the software even better.
