Your microphone keeps cutting out during Discord voice calls, and you suspect the voice suppression feature is the cause. Discord’s built-in noise suppression can sometimes be too aggressive, muting or distorting your voice when there is any background noise or even during brief pauses. This problem typically occurs because the suppression algorithm interprets your speech as noise and reduces the audio input. This article explains why voice suppression causes microphone cutouts and provides step-by-step fixes to resolve the issue.
Key Takeaways: Fixing Discord Voice Suppression Microphone Cutouts
- User Settings > Voice & Video > Advanced > Noise Suppression: Disable or lower the suppression level to prevent aggressive muting of your voice.
- User Settings > Voice & Video > Advanced > Echo Cancellation: Disable this feature if it conflicts with noise suppression and causes cutouts.
- User Settings > Voice & Video > Reset Voice Settings: Restore all voice settings to defaults to clear any corrupted configuration.
Why Discord Voice Suppression Cuts Off Your Microphone
Discord uses a noise suppression algorithm based on machine learning to filter out background sounds like keyboard clicks, fans, or traffic. The algorithm analyzes the audio stream in real time and attempts to separate speech from noise. When the algorithm is set to a high suppression level, it may incorrectly classify your voice as noise, especially if you speak softly, pause between words, or have a microphone that picks up subtle room sounds. This results in the microphone being temporarily silenced or producing a choppy audio output.
How the Suppression Algorithm Works
The suppression technology uses a neural network trained on thousands of audio samples. It identifies patterns that match speech and allows those through while reducing everything else. The aggressiveness of this filtering is controlled by the Noise Suppression setting in Discord’s Voice & Video menu. At the highest level, Standard, the filter can be overly sensitive, causing voice cutouts in normal conversation.
Conflicts with Other Audio Processing
Discord also includes echo cancellation, automatic gain control, and noise reduction. When multiple processing features are active simultaneously, they can interfere with one another. For example, echo cancellation may attempt to remove what it thinks is echo from the microphone input, further muting your voice. This combination of active features is a common cause of microphone cutouts.
Steps to Stop Discord Voice Suppression from Cutting Off Your Mic
Follow these steps in order. Test your microphone after each step to identify the specific setting causing the issue.
- Open Discord User Settings
Click the gear icon in the bottom-left corner of the Discord window next to your username and avatar. This opens the User Settings menu. - Navigate to Voice & Video Settings
In the left sidebar, scroll down to App Settings and click Voice & Video. This section contains all audio input and output controls. - Disable Noise Suppression
Scroll to the Advanced section. Locate the Noise Suppression dropdown. Select Off from the options: Off, Standard, or Krisp. Krisp is Discord’s most aggressive AI-based suppression. Turning it off stops the algorithm from filtering your voice. - Disable Echo Cancellation
Directly above the Noise Suppression setting, find the Echo Cancellation toggle. Set it to the off position. This prevents the system from trying to remove audio that it mistakenly identifies as echo from your speakers. - Disable Noise Reduction
Below Noise Suppression, locate the Noise Reduction toggle. Turn it off. This is a simpler filter that can also cause voice cutting. - Disable Automatic Gain Control
Find the Automatic Gain Control toggle and turn it off. This feature adjusts microphone volume automatically, which can cause sudden drops when it misinterprets your speech level. - Test Your Microphone
In the same Voice & Video section, speak into your microphone. Watch the input volume bar. It should show consistent green bars when you speak and drop to no bars when you are silent. If the bar cuts out while you are speaking, the suppression is still active. - Reset Voice Settings as a Final Step
If the problem persists, scroll to the bottom of the Voice & Video page and click Reset Voice Settings. Confirm the reset in the pop-up dialog. This restores all voice settings to their defaults, removing any corrupted configuration.
If Discord Still Has Microphone Cutouts After the Main Fix
Disabling Discord’s audio processing often resolves the issue, but sometimes the problem is caused by other factors. Below are additional scenarios and their fixes.
Microphone Cutouts Only in Specific Voice Channels
If the cutouts happen only in certain servers or channels, the server owner may have enabled server-level voice suppression. Ask the server admin to check Server Settings > Roles > Manage Permissions and look for the Use Voice Suppression permission. This permission can force suppression on all members. The admin can disable it for your role or for the @everyone role.
Microphone Cutouts on Mobile Devices
On the Discord mobile app, open User Settings > Voice & Video. Under Audio Processing, toggle off Noise Suppression and Echo Cancellation. Mobile devices often have additional system-level audio processing that cannot be changed within Discord. If the problem continues, try using a wired headset instead of Bluetooth, as Bluetooth introduces additional audio compression that can cause cutouts.
Microphone Cutouts Caused by Windows Audio Enhancements
Windows has its own audio enhancements that can conflict with Discord. Right-click the speaker icon in the Windows system tray and select Sound settings. Under Input, click the microphone device, then click Device properties. In the new window, go to the Additional device properties link. On the Enhancements tab, check Disable all enhancements. Click Apply and OK. Restart Discord.
Microphone Cutouts with USB or Bluetooth Headsets
USB and Bluetooth headsets have their own drivers and processing. Disable any headset-specific noise cancellation in the headset’s companion software, such as Logitech G Hub or SteelSeries GG. Also ensure the headset is set as the default input device in Windows Sound settings. In Discord’s Voice & Video settings, confirm the correct input device is selected under Input Device.
Discord Voice Suppression Settings: Off vs Standard vs Krisp
| Item | Off | Standard |
|---|---|---|
| Description | No noise filtering applied | Basic noise reduction uses machine learning to filter constant background sounds |
| CPU Usage | None | Low |
| Impact on Voice | No voice cutouts | Can cause voice cutouts in quiet speech or pauses |
| Best For | Quiet environments or when using external noise filtering | Moderately noisy environments where background sounds are consistent |
Discord previously offered a Krisp option, which provided the most aggressive AI-based suppression. Krisp is now integrated into the Standard mode. The table above compares the two current available options.
You now know how to stop Discord voice suppression from cutting off your microphone. Start by turning off Noise Suppression, Echo Cancellation, and Automatic Gain Control in User Settings > Voice & Video. If the issue continues, check Windows audio enhancements and your headset’s companion software. For persistent problems, resetting Discord’s voice settings clears all custom configurations and is the most reliable last resort.
