Nvidia's new 30-series graphics cards promise amazing performance gains, with the $500 RTX 3070 outperforming the 2080 Ti. But Nvidia is also touting other features exclusive to its graphics cards, and one of the new features to be announced in September, Nvidia Broadcast, seems to be useful for nearly everyone who uses a gaming PC. Broadcast is built on top of RTX Voice Broadcast is an app built on RTX Voice that makes it easy for streamers and anyone else who uses a webcam and voice chat to talk simultaneously while playing games.

When Nvidia announced RTX Voice as a beta earlier this year, we marveled at its ability to cut through background noise from the loudest fans to the most clunky mechanical keyboards. For the most part, it works better than any noise-canceling technology we've seen (although a recent driver update turned Executive Editor Tyler Wild into a static monster in some of our video meetings). It works based on the "power of AI," and while buzzwordy, it's hard to argue with the results.

Like RTX Voice, Nvidia Broadcast has a microphone and input audio noise reduction feature. Looking at the interface in the demo video above, it appears that Broadcast has other effects to apply to the input audio as well as noise reduction. Perhaps you can make your friends sound like they are underwater.

In the current application, applying RTX Voice to input audio does not help in all situations, as it filters out all audio output, including game audio and music. broadcast seems to be the same, but with sirens outside the window. It would be quite useful to chat with someone without hearing sirens blaring outside your window.

Broadcast also offers some AI-driven webcam features: virtual background replacement that scans your face and can blur the room behind you or replace the image entirely. This is a fairly standard feature of video chat software like Zoom, and while you can't expect it to be as clean as a proper green screen, it's a nice feature for streamers who don't want to mess with extra hardware.

Auto Frame is another useful webcam tool. It "zooms in on you and uses AI to track your head movements, keeping you in the center of the action even if you move left or right." Again, multi-angle and camera crop are things that can be set up with more hardware or software presets like OBS, but Nvidia has simplified the process. Auto Frame and Virtual Background are two of the most useful features, as is RTX Voice, which is launched as a beta to polish the AI, as was the case with RTX Voice. [Broadcast will work with any RTX card. Most people won't care about video features, but RTX Voice's improved ability to erase background noise alone will be a boon to those who have purchased new Nvidia cards.
