Note: For Installation and Starting of the Mumble Client, see the specific Userguides for your Operating System.
Click on Configure->Settings or on the 
-symbol to open the Configuration Menu.
Below you find a list with the most important options.
Tip: A small description of each option is displayed, when you hover your mouse pointer over it.
If enabled, this will filter echo from the audio you send to others.
You should usually enable it, because even when you use headsets, they might transmit undesired noise.
Choose one of the following options:
| Option: | Description: | Usecases: |
|---|---|---|
| Mixed echo cancellation | This is the basic Option: It will process all loudspeaker outputs bundled together. This is less accurate than the Multichannel option, but will also use less CPU. | Sufficient for setups with loudspeakers near to the microphone. |
| Multichannel echo cancellation | Extended option: This will process all audio channels seperately, this is more accurate, but will result in higher CPU usage. | For setups with (multiple) loudspeakers farther away from the microphone. |
| Disabled | Disables echo cancellation (not recommended). | - You use a very good headset. - Or you use external echo cancellation (for example via pulseaudio on Linux). - Echo cancellation is causing problems. |
You can choose between three transmission modes:
- Push to Talk
Your voice is only transmitted when you press a button.
You can set the button in the Shortcuts-Menu (see below).
- Voice Activity
Your voice is only transmitted when a certain limit (loudness) is reached. All noise below the limit will be canceled.
Tip: Use the Audio Wizard(Configure->Audio Wizard) to configure this option correctly.
The coloured bar will show the noise-level when you speak, adjust Silence below (everything below the marker will not be transmitted) and Speech above (everything above the marker will be transmitted) accordingly.
- Continuous
All Audio from your microphone will be transmitted continuously.
Note: You should usually not use this option, as it can be very annoying for listeners. It is intended for special usecases (Music bots, Recording etc.) or when you use external tools for audio filtering instead.
| Option: | Description: |
|---|---|
| Quality | Sets the maximum bandwidth the client will try to accomplish (it is limited by the Server you are connected to). Setting it higher will increase the audio quality. Only set it higher if your internet connection is good enough. |
| Audio per packet |
RNNoise
RNNoise is a noise suppression library. It is intended to filter background noises from the audio that you send sent to other users. RNNoise uses a deep learning algorithm so it should work better than most regular filters.
More information can be found on various websites:
If enabled, it implements a small window inside other applications (mostly Games), that will show the users and their status in your Mumble channel.
| Tab: | Description: |
|---|---|
Layout |
adjust the position of the window |
Overlay Exceptions |
you can either specify a list of programs where the overlay is allowed (whitelist) or where the overlay is denied (blacklist). |
