What Is NVIDIA Broadcast? The Desk's Explainer

A free app with a hardware price tag: RTX 2060 or better, Windows only, and no help at all on a Mac or an AMD card.

NVIDIA Broadcast is a free Windows application that runs on your graphics card and cleans the microphone signal while you speak. It needs an RTX 2060 or better with 8 GB, it is Windows only, and there is no macOS or AMD version. Its predecessor was RTX Voice, which it replaced. So the price is not really zero: it is paid in silicon rather than dollars, and that one fact settles most of the question. The desk's verdict is below, along with what to run when the requirement rules you out. Most people asking this are asking from a laptop that has never held an RTX card, with a housemate on a call in the next room.

What the app does, and what it does not

Broadcast installs as a virtual device. You choose it as your input inside each app — the meeting client, Discord, OBS — rather than picking the physical microphone, and everything you say passes through the model on the way out. That is the whole shape of it: a filter on a live signal. It cannot reach back into a recording you already made, and it cannot help a colleague whose own microphone is the noisy one on the call.

• An RTX 2060 or better with 8 GB. There is no software route around a card that sits below that line.
• Windows. There is no macOS build and no AMD build, so the answer on either is a different tool entirely.
• GPU headroom, because the work lands on the same card you are using for the game or the render.
• The virtual device selected app by app, since nothing switches over on your behalf.
• No money. The app is free, and that is the part of the deal people quote most often.

Free is doing a great deal of work in that last line. The download costs nothing and the hardware costs plenty, so the honest description is free-with-a-prerequisite. If the prerequisite is already sitting in your desktop for other reasons, the marginal price really is zero and the app is a straightforward win. If it is not, the money you would spend to qualify buys several years of a subscription that runs on the processor you already own.

RTX Voice, and why it is not the answer now

RTX Voice came first and Broadcast replaced it. That is the entire relationship, and it is worth stating plainly because the older name still carries a lot of search traffic. Both are NVIDIA's own, both run on the graphics card, and neither has ever run on anything else. If you are choosing today on supported hardware, you install Broadcast; the legacy product is a footnote rather than a recommendation.

What owners of older cards keep asking

The question underneath most RTX Voice searches is whether a non-RTX card can be made to run it. This desk does not publish workarounds for that, and it will not link community patches that bypass a hardware check — unsigned code sitting between your microphone and your employer's calls is a poor trade for a quieter fan. The supported routes are duller: a CPU-based tool on Windows or macOS, AMD's own free noise suppression in its Adrenalin software if the card is AMD, or the Voice Isolation microphone mode built into macOS. None of them need a specific graphics card, and none of them will fix the fact that your desk sits four feet from a coffee machine.

Installing it, and the two mistakes people make

Get it from NVIDIA's own site and nowhere else. Before you download, check the card, check that you are on Windows, and update the driver — three checks that take a minute and save an evening. Then install, restart the apps you want it in, and go looking for the input picker in each one. Our NVIDIA Broadcast review walks the same path with the desk's notes on where it holds up and where it does not.

Mistake one is leaving the physical microphone selected. The app can be running perfectly and doing nothing, because the meeting client is still listening to the hardware. Open the audio settings in each app and select the virtual device by name. Mistake two is stacking filters: if the app also has its own suppression switched on, two models are now arguing over your consonants, and the result sounds worse than either alone. Discord is where this shows up most, since its voice settings present a Krisp-branded suppression option next to a standard one — pick one and turn the rest off.

If the card rules you out, the alternative is a CPU-based tool. The Krisp review covers the one this desk has tested most: desktop-only live cleanup on Windows 10 or 11 and macOS, processed on-device, free for 60 minutes a day with no credit card, then $8 a month billed annually. The install path is short, and where to get Krisp is written up separately. Compare the wider field in the noise suppression ledger before you commit to either camp.

Edge cases the requirement list does not cover

It is running and the far end still hears the room

Check the input selection first, then check whether a second suppression layer is fighting it. After that, consider the noise itself: a model trained to strip steady sound handles a fan well and a television badly, because a television is a voice, and voices are what the model is trying to keep.

It works in one app and not another

That is expected. The virtual device is selected per application, so a fresh install of a meeting client, a browser update or a new headset can quietly reset the choice. Make the input picker part of your pre-call habit rather than something you visit after a complaint.

The GPU is busy and the audio turns choppy

Broadcast runs on the same card as your game or your render. When that card is saturated, audio processing competes for it. This desk publishes no frame-cost figure, because the honest number is the one you measure on your own machine — run the same scene twice, once with the filter on, and compare what you see. It is also the point where the difference between what noise cancellation means on a card and on a processor stops being academic.

Questions the desk gets asked

Is NVIDIA Broadcast free?

Yes. The application costs nothing to download and nothing to use. The cost sits in the requirement: an RTX 2060 or better with 8 GB, on Windows. If that card is already in your machine, the price really is zero. If it is not, buying one to qualify is the most expensive free software decision available to you.

What is NVIDIA Broadcast used for?

Cleaning a live microphone signal on a Windows PC with an RTX card. It installs as a virtual device, you select it as the input inside each app, and it processes what you say on the graphics card as you speak. It does not repair recordings that already exist.

Does NVIDIA Broadcast work on a Mac?

No. There is no macOS build. On a Mac the free option is the Voice Isolation microphone mode built into the operating system, and the paid option is a CPU-based tool that installs as a virtual microphone and processes the audio on the machine itself. Both leave your calls on the laptop rather than sending them out.

Is NVIDIA Broadcast the same as RTX Voice?

No. RTX Voice is the legacy predecessor and Broadcast is what replaced it. If your hardware qualifies, install Broadcast. The reason RTX Voice still appears in searches is that owners of older cards keep hoping it will run where Broadcast will not, which is not a route the desk is willing to recommend.

What should AMD owners run instead?

AMD ships free noise suppression for AMD graphics cards inside its Adrenalin software, so start there before you buy anything at all. If the result is not enough, a CPU-based tool works on any hardware and costs processor time rather than card time — the free tier is 60 minutes a day, with no card required to begin.
