NVIDIA RTX Voice Explained: Noise Removal Setup and Supported GPUs

NVIDIA RTX Voice is a noise-removal feature that uses AI running on your graphics card to filter background sounds, such as keyboard clicks, fans, and room echo, out of your microphone and, optionally, out of incoming audio from other people. It has since been folded into NVIDIA Broadcast, which offers the same noise removal along with video effects and is the version to use today.

Setup is simple: install the current software, pick your real microphone as the input, switch on the noise removal effect, and then choose the virtual NVIDIA microphone inside your chat or recording app. This guide explains what it does, how it relates to Broadcast, which GPUs it works with, step-by-step setup, and its limits.

What RTX Voice Does

RTX Voice runs a trained neural network on the GPU’s Tensor hardware to separate speech from other sounds in real time. It creates a virtual audio device that sits between your actual microphone and the application you are using, so apps like Discord, Zoom, Microsoft Teams, OBS Studio, and game chat receive the cleaned-up audio.

It can work in two directions. The microphone side cleans what you send, while the speaker side cleans what you hear, which helps when other participants are on noisy microphones. Because it runs on the GPU rather than the CPU, it leaves processor capacity free for games and streaming software.

RTX Voice vs NVIDIA Broadcast

RTX Voice launched as a standalone beta, and NVIDIA later released NVIDIA Broadcast as a successor application. Broadcast keeps the noise removal feature and adds camera effects, including virtual backgrounds, auto frame, and eye contact, as well as a room echo removal effect for audio. For new setups, Broadcast is the version to install and the one the manufacturer actively maintains.

Feature sets change between versions, so check the manufacturer’s current documentation for the exact list available in the release you install.

Supported GPUs and System Requirements

NVIDIA Broadcast is intended for GeForce RTX graphics cards, which include the Tensor hardware needed for the AI models. RTX Voice at launch was positioned for RTX cards, and community reports of it running on older GTX cards were unofficial and unreliable. If you have an older GPU, check the manufacturer’s current documentation, and consider software-based noise suppression built into your chat app or microphone driver instead.

• GPU: a GeForce RTX card, or a supported RTX professional card, in a desktop or laptop.
• Operating system: Windows is the supported platform; the software is not designed for macOS or Linux.
• Driver: a recent NVIDIA graphics driver, since the features depend on up-to-date driver components.
• Audio device: any microphone, including USB, headset, or XLR interface input.

How to Set It Up

Install the software

Download NVIDIA Broadcast from the manufacturer’s official downloads page, or use the NVIDIA App if it offers the package. Run the installer, accept the terms, and restart if prompted. Keep your graphics driver current so the software has the components it needs.

Choose your microphone and effect

Open the Broadcast app and select the Microphone tab. Choose your real microphone from the device list, then add the Noise Removal effect. Many versions include an intensity slider; start near the default and adjust until background sounds fade without making your voice sound thin or clipped.

Use the virtual device in your apps

In Discord, OBS Studio, Zoom, or another application, open the audio settings and select the NVIDIA Broadcast microphone as your input rather than your physical microphone. If you choose the physical one, your audio bypasses the filter. Do the same on the speaker side if you want incoming audio cleaned, selecting the Broadcast speaker as the playback target.

Check the result

Record a short clip or use your chat app’s microphone test, and play it back with typical background noise present. Adjust the intensity or microphone gain if speech is cut off or if noise still leaks through.

Limitations to Know About

• GPU usage: the effect uses a share of GPU resources, which can matter in demanding games on mid-range cards, so watch frame rates in your own setup.
• Not perfect on all sounds: it targets steady background noise and typing best; other voices, music, and sudden noises may partly leak through or be altered.
• Speech artifacts: aggressive settings can clip syllables or make speech sound processed.
• Latency: processing adds a small delay, usually unnoticeable in chat, but worth checking if you monitor your own voice live.
• Compatibility quirks: some apps apply their own noise suppression, and stacking two filters can produce odd results, so use one at a time.
• Hardware dependence: it needs a supported RTX card, so it is not an option for every PC.

Troubleshooting Common Problems

Other people cannot hear me

Check that your chat app is set to the Broadcast microphone and that the Broadcast app itself is using the correct physical microphone. Make sure the physical microphone is not muted in Windows sound settings.

The effect is not available

Confirm that the GPU is a supported RTX model and that your driver is current. If Broadcast was installed before a major driver change, reinstalling it often restores the effects list.

Voice sounds robotic

Lower the effect intensity, reduce microphone gain so the input is not clipping, and test again. Turning off a second noise suppression feature in your chat app is also worth trying.

Game performance drops

Try turning off other GPU-heavy effects, such as camera background effects, or use the speaker-side cleanup only when needed. On lower-end cards, an in-app noise suppression feature may cost less performance.

Tips for Better Results

AI noise removal works best when the microphone signal is already reasonable. A filter can suppress a fan or keyboard, but it cannot recover speech that was recorded too quietly or distorted at the source. A few simple habits improve results more than any software setting.

• Position the microphone close: a closer mic captures more of your voice relative to background sound, so the filter has an easier job.
• Set gain sensibly: avoid peaks that clip, since clipping creates distortion that the filter may treat as part of the signal.
• Use one filter at a time: if your chat app has its own noise suppression, turn it off while Broadcast runs, or the combined processing can sound thin.
• Review for streaming: if you stream, check that your capture software is listening to the Broadcast microphone and not to both devices at once.
• Keep drivers current: updated drivers and the latest Broadcast release tend to fix audio device problems.

If you share a room with other people, keep expectations realistic. The filter targets sounds that differ from speech, so a second person talking nearby may still be picked up. A directional microphone, such as a dynamic model, reduces what reaches the filter in the first place and pairs well with the software.

Frequently Asked Questions

Is RTX Voice the same as NVIDIA Broadcast?

Not exactly. RTX Voice was the earlier standalone noise-removal application, and NVIDIA Broadcast is its successor, which keeps noise removal and adds camera and other audio effects. For a new install, use Broadcast.

Do I need an RTX graphics card?

Yes, the supported route is a GeForce RTX card or a supported RTX professional card. Unofficial workarounds for older cards exist but are not guaranteed, so check the manufacturer’s current documentation.

Does it work with any microphone?

It works with most microphones that Windows recognizes, including USB, headset, and interface inputs. Good microphone placement and gain still matter, because the filter cannot fully repair a poor signal.

Will it reduce my game performance?

It uses some GPU capacity, so there can be a small cost, especially on mid-range cards in demanding games. Watch your own frame rates, and lower the effect settings if you notice a drop.
