NVIDIA Broadcast is a free Windows app that uses AI to clean up microphone and webcam feeds for streaming, video calls and recording — removing background noise and room echo, blurring or replacing your webcam background, auto-framing your shot, and simulating eye contact and studio-style relighting. It's built for streamers, remote workers and anyone taking video calls from an untreated room who wants studio-grade cleanup without editing anything after the fact. The app itself costs nothing, but it only runs on NVIDIA GeForce RTX, Quadro RTX or TITAN RTX GPUs, so the real gate is owning qualifying hardware, not a subscription.
Who builds it
NVIDIA builds and ships Broadcast as a free companion app for GeForce RTX GPU owners, built on the same NVIDIA Maxine AI-effects technology that powers noise removal and camera effects across NVIDIA's product line. The core workflow: install Broadcast, and it creates a virtual microphone and a virtual camera device that any other app — Zoom, Discord, Microsoft Teams, OBS, Twitch — can select as its input. The AI effects then apply live to whatever software you're already using, without that software needing native support for them.
Core features
- Noise Removal and Room Echo Removal: AI models strip background noise and reverb from a live microphone feed in real time.
- Studio Voice: an AI equalizer that makes a microphone sound closer to higher-end studio equipment (requires a GeForce RTX 3060 desktop GPU or higher).
- Virtual Background: remove, replace or blur the webcam background without a physical green screen.
- Auto Frame: dynamically crops and tracks the presenter's position in the frame, simulating a camera operator.
- Eye Contact and Virtual Key Light: simulates looking directly at the camera and applies AI-based face relighting (Virtual Key Light also requires RTX 3060 or higher).
- Runs as virtual mic/camera devices, so effects work inside Zoom, Teams, Discord, OBS and other apps without those apps needing built-in support for them.
Pricing
- NVIDIA Broadcast itself is a free download — there is no paid tier, subscription or watermark on the app.
- The real cost is hardware: it requires a GeForce RTX 2060, Quadro RTX 3000, TITAN RTX or higher GPU; some effects (Studio Voice, Virtual Key Light) specifically need an RTX 3060 desktop GPU or higher.
- Windows 10 64-bit only (NVIDIA Studio Driver or Game Ready Driver R570+); there is no macOS or Linux version.
- Developers who want the same AI effects inside their own applications, rather than using the Broadcast app itself, can integrate them for free via the NVIDIA Maxine SDKs (Audio Effects SDK, Video Effects SDK, AR SDK) — the same technology already used by apps like OBS Studio, Streamlabs, Elgato tools, XSplit and VTube Studio.
Who it's for
Streamers, podcasters, and remote workers who already own or are buying a GeForce RTX-class GPU and want studio-grade mic and camera cleanup without paying for a separate noise-cancellation subscription. It's not a fit for laptop users on integrated graphics, older GTX-series cards, or Mac users — none of those can run it at all, since Broadcast requires a qualifying RTX/Quadro RTX/TITAN RTX GPU and Windows. Because the app is free, there's no upgrade-tier decision to make; the only real gate is whether you already have (or plan to buy) the required GPU.
