How to Remove Background Noise in Discord
Turn on Discord's Krisp noise suppression for a live call, and what to check when it switches itself off. Krisp does not clean a recording you already exported.
Discord can hide a fan, a dog, or a slamming door on a live voice chat. The switch is Krisp, and it only changes what other people hear from your microphone. It does not open a video you already saved.
Key Takeaways
- Discord's Krisp setting is built for non-speech noise such as dogs, vacuums, and doors.
- It filters your side of the call only. Other people still need it enabled on their own Discord.
- Krisp turns itself off when the device is too busy. Lower the load, then turn it on again.
- A quiet room and a good microphone can sound worse with Krisp on. Leave it off in that case.
What Krisp does on a call
Discord's help article says Krisp is third-party noise filtering that runs on your device. On Discord it removes background noises that are not human voices, and the examples are dogs barking, vacuums, and doors slamming, while your voice still goes through. Discord says no voice, user, or video data is sent to Krisp. The model stays on the device. (Krisp FAQ, updated March 25, 2025.)
Krisp is free inside Discord. The standalone Krisp app, for other programs, is a separate product with its own price.
It will not clean a friend's noisy mic. Discord is explicit: Krisp filters noises coming from your side. If you are the one hearing the noise, the other person has to enable it.

Turn it on
On the desktop app, Discord documents two paths:
- Join a voice channel and use the Noise Suppression icon, then enable Krisp.
- Or open User Settings beside your avatar, go to Voice & Video, and under Noise Suppression select Krisp.
On the phone:
- In a voice channel, tap the channel name at the top left, find Noise Suppression, and enable Krisp.
- Or tap your avatar, open the settings cog, go to App Settings, then Voice, then Noise Suppression.
Once it is on, Discord says it stays on for new voice chats until you turn it off. It also works on the audio of a video call, and in a Go Live voice channel.
Krisp on Discord is supported on Windows, Linux, Mac, Android, and iOS. Mac needs Apple silicon and macOS 12 or later. As of October 30, 2023, the browser version Discord documents is Chrome and Firefox on desktop.
When it keeps turning off, or the voice sounds worse
Discord's FAQ answers the two problems people usually mean by "noise suppression is not working."
It switches off by itself. When CPU use is very high, Krisp turns off to protect the call and tells you. Lower whatever else is loading the machine, then enable Krisp again. If the machine is still busy, it will turn off again. (Krisp FAQ, updated March 25, 2025.)
The voice sounds worse than with it off. Discord says Krisp is for places with a lot of non-speech noise. In a quiet room, with a high-quality microphone, it can reduce voice quality. Leave it off there.
You still hear the other people. That is expected. Their Discord has to run Krisp too.
You are trying to fix a saved clip. Krisp never sees that file. Export the audio or clean the video with a file tool. The general cleanup guide covers a saved video. Adobe Podcast Enhance Speech is another upload path. EraseNoise can preview the saved file on the video noise remover.
A bark that happens live is one of Discord's own examples for Krisp. A bark that is already inside an exported file is a different job, covered in removing dog barking from a recording.
