Introduction to NVIDIA Broadcast

NVIDIA Broadcast harnesses the power of AI to transform standard webcams and microphones into high-end smart devices, helping users transform any space into a home studio. Improve the video and audio quality of live broadcasts with AI features such as microphone denoising, room echo cancellation, virtual backgrounds, webcam portrait tracking, and video noise reduction. The AI ​​network can run high-quality effects in real time through the Tensor Core dedicated AI processor on the NVIDIA RTX GPU.

You'll want to select this virtual device (named NVIDIA Broadcast) in your live broadcast or video conferencing application.

advanced settings

About multi-effects: In version 1.2 and above, you can combine multiple AI effects for each device. Running multiple effects can increase your app's GPU resource usage. To add secondary effects, just click the "Add Effect" button. To remove an effect, click on the effect name and scroll down to "xRemove this effect". Avoid issues with third-party filters : Apps sometimes use effects similar to those in NVIDIA Broadcast, such as denoising. Applying an effect twice often causes the effect to render incorrectly. We recommend disabling such effects in your applications and drivers. Changing the resolution : If you need to adjust the resolution of the camera, you need to do it through NVIDIA Broadcast. In live streaming/video conferencing applications, the default setting should be left or match the NVIDIA Broadcast setting. If you changed the resolution of your webcam in NVIDIA Broadcast, you will need to reload the camera in the app (aka close the app and reopen it, if it is not set to "auto", you will need to adjust the resolution). If you often connect/disconnect with microphone/speaker: If you frequently switch microphone and speaker (i.e. plug and unplug frequently), you can select (default device) as input for NVIDIA Broadcast. This will automatically use whatever microphone/speaker Windows detects as the new default device input, saving you from having to reconfigure each time. Set NVIDIA Broadcast as default device in Windows Sound Settings: In Windows, you can select NVIDIA Broadcast as your default microphone so you don't have to change it in every app. If you choose this option, make sure to select the actual microphone in NVIDIA Broadcast. Do not do this to the speakers as doing so will start filtering all audio coming from the device like video and music.

Test Methods

The NVIDIA Broadcast app has built-in testing: To test your microphone, record audio in an environment with background noise. Now you can play the file and turn the effect on or off, or adjust the intensity, to see the difference the effect makes. To test your speakers, we have provided some recording files that you can listen to with the effect on or off to compare the effect. You can also adjust the strength of the effect. To test the webcam, simply use the preview window.
