This article explains how to enable Krisp, adjust its settings, and understand its limitations. You will learn the exact steps to activate Krisp on desktop and mobile, along with tips to get the best results.
Key Takeaways: Using Discord Krisp Noise Suppression
- User Settings > Voice & Video > Noise Suppression: Select “Krisp” to enable real-time noise reduction on your microphone.
- Server Boost or Nitro Subscription: Krisp is free for all users, but some advanced features require a paid plan.
- Voice Channel Noise Suppression Toggle: You can also enable Krisp per voice channel by clicking the noise suppression icon next to your name.
What Is Discord Krisp and How Does It Work
Discord Krisp is a machine learning-based noise suppression system developed by Krisp.ai. It runs locally on your computer or mobile device, processing audio in real time to remove non-speech sounds. Unlike simple noise gates that cut audio below a threshold, Krisp analyzes the audio waveform and separates speech from background noise. This allows it to preserve your voice quality while eliminating sounds like typing, air conditioning, or street noise.
Krisp works with any microphone and does not require special hardware. It operates at the system level, meaning it affects all audio going through Discord, including voice calls and voice chat in games. The feature is available on Discord desktop for Windows and macOS, as well as on the Discord mobile app for iOS and Android.
Prerequisites for Using Krisp
To use Krisp, you need a Discord account and the Discord app installed on your device. Krisp is enabled by default for all users on desktop and mobile, but you may need to adjust settings if it was turned off. No additional downloads or purchases are required for the basic noise suppression feature. However, some server-specific noise suppression options may require a Nitro subscription or Server Boost.
Steps to Enable Krisp Noise Suppression on Desktop
- Open Discord and go to User Settings
Click the gear icon next to your username at the bottom left of the Discord window. This opens the User Settings menu. - Navigate to Voice & Video settings
In the left sidebar, scroll down and click Voice & Video under the App Settings section. - Locate the Noise Suppression dropdown
Under the Voice Processing section, find the Noise Suppression dropdown menu. It is set to “Standard” by default, which uses a basic noise gate. - Select Krisp from the dropdown
Click the dropdown and choose Krisp. The setting takes effect immediately. You can test it by speaking into your microphone and asking someone to confirm the background noise is reduced. - Optional: Adjust advanced settings
Below the Noise Suppression dropdown, you can also enable Echo Cancellation and Noise Reduction for additional audio processing. These work alongside Krisp but may increase CPU usage.
Steps to Enable Krisp Noise Suppression on Mobile
- Open the Discord mobile app
Launch Discord on your iOS or Android device. Tap your profile picture in the bottom right corner to open User Settings. - Go to Voice Settings
Scroll down and tap Voice under the App Settings section. - Enable Krisp Noise Suppression
Under the Noise Suppression section, tap the toggle next to Krisp. The toggle turns blue when enabled. You can also choose between “Standard” and “Krisp” from the dropdown if available. - Test the setting
Join a voice channel or start a voice call. Speak while background noise is present to verify Krisp is working. You may need to ask the other person if they hear less background noise.
Common Issues with Krisp Noise Suppression
Krisp Option Is Grayed Out or Missing
If the Krisp option is grayed out or not visible, your device may not meet the minimum system requirements. Krisp requires a 64-bit operating system and a relatively modern CPU with SSE4.2 support. Older computers, especially those running 32-bit Windows, may not have the option. Update Discord to the latest version and check your OS architecture by going to Settings > System > About on Windows or About This Mac on macOS.
Krisp Causes High CPU Usage
Krisp processes audio in real time, which can increase CPU usage. On low-end devices, this may cause audio lag or stuttering. To reduce CPU load, close other applications that use audio processing, such as streaming software or virtual audio cables. You can also switch back to Standard noise suppression if performance issues persist.
Krisp Does Not Remove All Background Noise
Krisp is trained to remove common background sounds like keyboard clicks, fans, and traffic. It may not eliminate very loud or irregular noises, such as a dog barking or a door slamming. For best results, position your microphone close to your mouth and reduce the background noise level as much as possible. Krisp works best when the noise is consistent and lower in volume than your voice.
Discord Krisp vs Standard Noise Suppression
| Feature | Krisp | Standard |
|---|---|---|
| Technology | Machine learning model | Basic noise gate with threshold |
| Noise removal | Removes non-speech sounds while preserving voice | Mutes audio below a set volume level |
| Voice quality | High, with minimal artifacts | Can cut off quiet speech or introduce artifacts |
| CPU usage | Moderate, higher than Standard | Low |
| Availability | All Discord users on desktop and mobile | All Discord users |
| Cost | Free for basic use | Free |
Standard noise suppression uses a simple noise gate that cuts audio when the volume falls below a threshold. This can result in your voice being cut off if you speak quietly. Krisp uses a more sophisticated AI model that identifies and removes background noise without affecting your speech. For most users, Krisp provides a noticeably cleaner audio experience, especially in noisy environments.
Discord Krisp noise suppression is a powerful tool for improving voice chat quality. By enabling it in User Settings > Voice & Video, you can reduce background noise and make your conversations clearer. Remember to test the setting with your specific environment and adjust your microphone position for the best results. If you experience performance issues, try closing other audio applications or switching back to Standard suppression. For advanced users, combining Krisp with a push-to-talk key can further reduce unwanted sounds.
