NVIDIA RTX Voice

NVIDIA RTX Voice is a new plugin that leverages NVIDIA RTX GPUs and their AI capabilities to remove distracting background noise from your broadcasts, voice chats, and remote video conferencing meetings.

Note: A new version of RTX Voice is available as ‘Noise Removal’ in the NVIDIA Broadcast app! Level up your livestreams, voice chats, and video calls with a suite of powerful AI effects like noise removal, virtual background, and auto frame.



This allows users to "go live" or join a meeting without having to worry about unwanted sounds like loud keyboard typing or other ambient noise in noisy environments.

RTX Voice plugin also suppresses background noise from players in loud environments, making incoming audio easier to understand. RTX Voice adds a virtual Microphone and Speakers within your system. They can then be selected in the most popular live streaming, gaming, and video conferencing apps including, but not limited to:

• OBS Studio
• Streamlabs
• XSplit Broadcaster
• Twitch Studio
• Discord
• Google Chrome
• Battle.net Chat
• WebEx
• Skype
• Zoom
• Slack
• Steam Chat

It creates a virtual device on your system, and it is this virtual device that we want to use in your voice chat apps to denoise background noise from chat only, and not from your general Windows audio (as it would denoise unwanted audio feeds, like YouTube videos, Spotify music, or game audio).

We recommend turning on the NVIDIA RTX Voice app for your microphone, and turn it on for your speakers only if needed. While quality remains almost the same, it is possible to see a small difference in some cases, and the solution takes system resources that you can avoid using if you don’t need it.

Setup Guide

• For NVIDIA RTX GPUs or higher, download NVIDIA Broadcast app.
• For NVIDIA GeForce GTX GPUs, download RTX Voice.

Install it.

Configure RTX Voice:

• Select the microphone and speaker you want to use.
• Turn on the background noise removal for the mic and/or the speakers.

Configure your voice chat app according to the instructions below. 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.

How to Test Background Noise Removal

To evaluate the effectiveness of RTX Voice for background noise removal, follow these steps:

• Setup: Ensure RTX Voice is set up according to the instructions provided above.
• Configure Sound Settings: In the Windows Sound Settings, select RTX Voice (Speakers) as your speakers.
• Test with Background Noise: Play a video or recording with background noise, such as a YouTube interview conducted on a busy street. Toggle the background noise removal feature on and off in RTX Voice (Speaker path) and observe the difference in audio quality.
• Revert Speaker Settings: After testing, revert your speakers in Windows to the default settings. Use RTX Voice as your speaker only in voice applications to avoid filtering audio you don’t want to, such as music or videos.
