What Nvidia Broadcast actually does
Broadcast isn't a driver tweak or a hardware trick. Per Nvidia's FAQ, it creates a virtual Windows camera, microphone, or speaker, so apps treat it like a physical device. You enable effects in the Broadcast app, then pick the Broadcast device in whatever app you're using.
The microphone effects Nvidia lists include:
- Noise Removal: strips distracting background sounds from your mic feed.
- Room Echo Removal: reduces the reverb common in small, untreated rooms.
- Studio Voice: an AI equalizer meant to make your voice sound as if it were recorded in a high-end studio.
BGR notes that noise removal and room echo removal are on by default in the audio tab. Studio Voice is a separate toggle.
Not every RTX card gets every feature
BGR says all RTX cards support Broadcast. That's broadly right for the app, but Studio Voice has a higher bar.
| Item | Requirement (per Nvidia) |
|---|---|
| Broadcast app (GPU) | GeForce RTX 2060, Quadro RTX 3000, TITAN RTX, or higher |
| Studio Voice | GeForce RTX 3060 or higher |
| RAM | 8 GB |
| OS | Windows 10 64-bit, Windows 11 64-bit, or Windows on Arm |
| Driver | 572.61 or newer on Windows; 617.42 or newer on Windows on Arm |
| Recommended CPU | Intel Core i5-8600 or AMD Ryzen 5 2600 or better |
| Installation | Internet connection required |
Release coverage from VideoCardz explains the Studio Voice cutoff. Broadcast 2.2.0 moved Studio Voice out of beta, and the updated model works on GeForce RTX 3060 desktop GPUs and higher. So an RTX 2060 owner can run the app, but shouldn't expect Studio Voice.
On versions: Nvidia's forum has a v2.3.0 feedback thread, and one user reported that the Nvidia app still showed v2.2.0 as the latest with no update option. UpdateStar lists 2.3.0 as the latest, released 10/14/2026. If you're on an older build and don't see an update, a manual download from Nvidia's site is the likely route.
What about GTX cards?
BGR mentions a workaround for older GTX cards. Nvidia is more blunt about it. The FAQ says the Broadcast app does not support GeForce GTX GPUs, because it relies on RTX Tensor Cores. For people who want to try AI noise removal without upgrading, Nvidia points to its older RTX Voice tool, which it says it patched to support GTX GPUs, with a caveat that results on older cards may vary. That is a different product from Broadcast, and it won't give you Studio Voice.
Setup: getting the processed audio into your apps
- Install Broadcast. Download it from Nvidia's site. Nvidia says it downloads AI models for your GPU during installation, and its setup guide puts the additional storage need at roughly 3 GB. Make sure you have a connection and free disk space.
- Pick your real microphone inside Broadcast. If you can't hear anything during testing, BGR's first suggestion is to check that the right mic is selected here.
- Choose your effects. Nvidia recommends turning on only what you need to avoid wasting GPU resources.
- Select the virtual mic in your app. In Discord, Teams, Zoom, OBS and similar apps, choose Microphone (NVIDIA Broadcast). In OBS Studio, for example, Nvidia's guide points to Mic/Auxiliary Audio under Settings > Audio.
- Optional shortcut: you can set the Broadcast microphone as the Windows default input, so you don't configure each app. Your real mic must still be selected inside Broadcast.
Pitfalls worth avoiding
- Don't make Broadcast Speakers your default output. Nvidia warns this filters all system sound, including music and video. If you only want a cleaner mic, leave your speakers or headset as the Windows output.
- Don't stack noise cancelling. Nvidia says applying a similar effect twice often leaves the result working incorrectly. Disable duplicate noise suppression in Discord, Teams, or your headset software while you test.
- Studio Voice and noise removal don't mix. Nvidia's setup guide says Studio Voice can't be combined with microphone background noise reduction. Pick one.
- Studio Voice is for non-gaming use. Nvidia says it uses a larger share of the GPU and doesn't recommend it while gaming or running GPU-intensive applications. It suits video calls, chat streams, and content creation.
Studio Voice mic profiles
Studio Voice offers four profiles that adjust tone: Default, Bright, Full, and Warm. Nvidia says Default adds no extra coloration. Bright is described as clear and sharp, Full as rich and deep, and Warm as soft, smooth, and bass-forward. Try a couple, since tone preferences vary from person to person.
How to test before you go live
Broadcast has a built-in microphone test. Record yourself speaking with some background noise, play it back, and toggle the effect on and off or adjust its strength. Do this before an important meeting, not during one.
Performance: what to expect
Nvidia says the cost depends on your GPU, game, webcam settings, and how many effects you run. Its own measurement is a 5–10% impact on a GeForce RTX 5090. That's one high-end card, not a promise for a midrange laptop GPU. If you notice slowdowns, turn off effects you don't need. You can also enable the GPU Utilization indicator in Broadcast's settings to see what each effect costs.
Reality check
BGR says Broadcast keeps out background chatter and noisy keyboards. Nvidia's documentation supports the general noise-removal idea but doesn't promise that every sound disappears. Results depend on your mic, room, voice, and settings. Nvidia's model card for Studio Voice describes it as enhancing speech captured with low-quality microphones in noisy or reverberant spaces. That's an enhancement, not a substitute for a decent mic placed sensibly.
For AMD users, BGR points to AMD Noise Suppression in Adrenalin Edition, under the Audio and Video settings, and says it's less effective than Broadcast. That is BGR's assessment, and I haven't tested it.
Bottom line
For RTX owners, Broadcast is a free, low-risk experiment: install it, choose the virtual mic, run the built-in test, and compare. Just remember the fine print. Studio Voice needs an RTX 3060 or better, it can't run alongside noise removal, and it's best kept out of your gaming sessions. If you're on a GTX card, Broadcast isn't the tool. The older RTX Voice is the only Nvidia option, with variable results.
