Discord Krisp noise suppression is a powerful tool that removes background noise from your voice calls. By default, Krisp applies to all voice channels you join. But you may want different noise suppression levels in different channels. For example, you might want full suppression in a public gaming channel but less suppression in a private meeting channel. This guide shows you how to enable Krisp noise suppression selectively per voice channel using Discord server permissions.
Key Takeaways: Selective Krisp Noise Suppression per Voice Channel
- Server Settings > Roles > Manage Permissions: Create a role that enables or disables Krisp permission for specific voice channels.
- Voice Channel Edit > Permissions > Advanced: Override the “Use Voice Activity” permission to control Krisp suppression per channel.
- Role Assignment: Assign the role to users only for the channels where you want Krisp suppression to apply.
How Discord Krisp Noise Suppression Works
Discord Krisp is a server-side noise suppression engine. When enabled, Discord removes background sounds like keyboard clicks, fans, and traffic from your audio stream before sending it to other users. Krisp is turned on or off per user in User Settings > Voice & Video > Noise Suppression. However, that setting applies to every voice channel you join. To make Krisp work differently in different channels, you need to use Discord’s permission system. The key is the “Use Voice Activity” permission. When a voice channel is set to Push to Talk (PTT) only, Krisp suppression still works but behaves differently. By combining Krisp settings with per-channel voice permissions, you can achieve selective suppression.
What You Need Before Starting
You need the “Manage Server” permission on the Discord server where you want to set up selective Krisp suppression. This permission is typically given to server administrators and moderators. You also need a Discord Nitro subscription to use Krisp. Krisp is a Nitro-only feature. If you do not have Nitro, you will not see the Krisp option in User Settings.
Steps to Enable Krisp Noise Suppression Selectively per Voice Channel
This method creates a custom role that forces Krisp suppression on for specific voice channels while leaving other channels unaffected. Follow these steps exactly.
- Open Server Settings
Right-click your server name in the server list on the left side of Discord. Select “Server Settings” from the dropdown menu. - Go to Roles
In the left sidebar of Server Settings, click “Roles”. Then click the “Create Role” button. Name the role something like “Krisp Voice” or “Noise Suppression”. Click “Save Changes”. - Configure Role Permissions
In the Roles page, click the role you just created. Scroll down to the “General Permissions” section. Find the permission named “Use Voice Activity”. Toggle it to the green checkmark (enabled). This permission allows users to use voice activity mode instead of Push to Talk. Krisp suppression works best with voice activity mode. Click “Save Changes”. - Create a Voice Channel
If you do not already have a specific voice channel where you want Krisp suppression, create one. In Server Settings, click “Channels”. Click “Create Channel”. Choose “Voice Channel”. Name it, for example, “Gaming with Krisp”. Click “Create Channel”. - Edit Voice Channel Permissions
In the Channels list, click the gear icon next to the voice channel you want to configure. Go to the “Permissions” tab. Click “Advanced Permissions”. Click “Add a Role” and select the role you created earlier (e.g., “Krisp Voice”). - Override the “Use Voice Activity” Permission for the Role
In the role permissions list for this channel, find “Use Voice Activity”. Set it to the green checkmark (allowed). This overrides the default permission for this role in this channel only. Other channels remain unaffected. Click “Save Changes”. - Assign the Role to Users
Go back to Server Settings > Roles. Click the role you created. Under “Role Members”, click “Add Members”. Search for the users who should have Krisp suppression in that specific channel. Select them and click “Add”. These users now have voice activity enabled in that channel, which allows Krisp to work most effectively. - Instruct Users to Enable Krisp in User Settings
Each user must turn on Krisp in their own Discord settings. They go to User Settings > Voice & Video > Noise Suppression and select “Krisp”. This is a user-level setting. The permission setup only ensures that voice activity mode is available in the channel, which gives Krisp the best environment to suppress noise.
What to Do If Krisp Does Not Activate in the Channel
Users Cannot See the Krisp Option
Krisp is a Nitro feature. If a user does not have an active Nitro subscription, they will not see Krisp in their User Settings. The only way to use Krisp is to have Nitro. There is no server-level override for this.
Krisp Is Enabled but Noise Still Passes Through
If Krisp is on but background noise is still audible, check the user’s input device. Krisp works best with a clear microphone signal. If the microphone is too quiet or too loud, Krisp may not filter effectively. Ask the user to adjust their input volume in User Settings > Voice & Video > Input Volume. Also, ensure the user is not using a hardware noise gate in their microphone software, which can interfere with Krisp.
Voice Channel Does Not Allow Voice Activity
If the voice channel is set to Push to Talk only, users cannot use voice activity mode. To fix this, go to the channel’s Permissions tab. Find the @everyone role or the specific role that needs voice activity. Set “Use Voice Activity” to the green checkmark. This allows users in that role to speak without holding a key.
Comparison: Krisp Suppression Modes
| Item | Krisp On (User Setting) | Krisp Off (User Setting) |
|---|---|---|
| Noise Suppression | Removes background noise like fans, keyboard, and traffic | No noise removal; all background sounds pass through |
| Voice Activity Required | Works best with voice activity enabled per channel | Works with both voice activity and Push to Talk |
| CPU Usage | Higher CPU usage due to real-time processing | No additional CPU load |
| Nitro Requirement | Requires active Nitro subscription | No Nitro needed |
You can now control where Krisp noise suppression applies in your Discord server. The key is using a custom role with the “Use Voice Activity” permission overridden per voice channel. Remember that each user must still enable Krisp in their own settings. For advanced control, consider creating multiple roles with different channel permissions. This way, you can have some channels with full Krisp suppression and others without any noise filtering.
