How to Set Up Microphone Noise Cancellation

Tap each step to follow along in order.

  1. Install NVIDIA Broadcast

    If you have an NVIDIA RTX graphics card, installing the NVIDIA Broadcast app gives you access to AI-based noise removal.

  2. Turn on Noise Removal

    In NVIDIA Broadcast, select your microphone as the input device, then turn on the "Noise Removal" effect to cut down on keyboard clatter and ambient noise.

  3. Route audio through the virtual microphone

    You need to select the virtual microphone device that NVIDIA Broadcast creates as your input in Discord or your game for the noise removal effect to actually apply.

  4. Turn on Discord's built-in noise suppression

    Under Discord's User Settings > Voice & Video, turning on the Krisp-based noise suppression option reduces background noise without needing any extra software.

  5. Adjust input sensitivity

    Combining noise suppression with input sensitivity settings (automatic or manual) lets you fine-tune things so your mic doesn't pick up sound during quiet moments.

  6. Test the effect with a real call

    Once you're set up, briefly call a friend or record yourself to check both how well noise is removed and whether your voice quality holds up.

You don't need an expensive microphone to sound clear

Keyboard clatter, fan noise, and everyday background sound are hard to eliminate even with a premium microphone. AI-based software noise removal gets you noticeably cleaner audio without buying any extra hardware.

Microphone placement still matters

Software noise removal works best as a supplement, not a replacement, for good basic setup. Keeping the microphone a consistent, moderate distance from your mouth and away from your PC's fans or speakers reduces the noise your software has to clean up in the first place.

Frequently Asked Questions

Which graphics cards support NVIDIA Broadcast?

It requires an NVIDIA RTX series graphics card. If you don't have one, Discord's own built-in noise suppression is a solid alternative.

Won't turning on noise removal make my voice sound unnatural?

In an especially noisy environment, part of your voice can get suppressed along with the background noise, so rather than maxing out the strength, it's best to test it by ear and dial in a level that still sounds natural.
