Installing Mumble on a desktop computer

These instruction cover installing mumble, the audio conference tool on a desktop computer. You can also install it on your android or iphones.

Please set aside about 10 minutes to complete the installation so you can properly run through the audio configuration wizard.

For best results use a headset or head phones.


First, visit the mumble download page to get the version that's right for your computer.

Install the software.

Windows users: You almost certainly want to install the Windows x64 Snapshot version, not the regular Windows version

Mac users If you are using a recent version and this bug is not yet fixed, after installing mumble, you may need to go to System Preferences->Security & Privacy->Privacy->Accessibility and enable access for Mumble.

Audio Wizard

When you start Mumble for the first time, it will prompt you to follow the audio setup wizard.

This process has about 4 screens with questions and takes about ten minutes.

If you have a headset or head phones, please use them while doing the wizard (and for all mumble calls).

Create certificate

Next, you will be prompted to create a certificate. A certificate is like a key that will grant you access to the server as the username you specify.

Add a server

Next, you must tell mumble what server you want to connect to. Click the add button.

Please enter:

  • Mayfirst
  • [Whatever username you want]

Please note: If you are re-installing mumble or starting over, you must pick a new username. You can't use the same username twice.

Connect to server

Now, you can click on the server you just entered and click Connect.


Once connected, be sure to mute yourself.

Join a meeting

You can join a meeting by dragging yourself to a room (aka Meeting).

Turn off text to speech

Hearing all text messages is irritating. Turn it off by clicking Settings and ensuring there is no check mark next to the "Text to Speech" menu item.

Configure Push to Talk

If using the Transmission setting Transmit: Push To Talk in the Audio Input pane in Mumble Configuration (Configure » Settings, Audio Input) and you cannot make yourself heard, you may need to configure or look up the push-to-talk shortcut. This is done under Configure » Settings, Shortcuts:

Push To Talk shortcut settings screen

In the Audio Input pane you can also checkmark "Display push to talk window" to get a floating always-on-top button you can click to talk, or of course switch to a different transmit setting. (If using Continuous instead, be sure to mute yourself when not talking.)

Audio Transmission Problems With Voice Activity

If people report trouble hearing you because parts of your words are cut off, check if you are using the Transmission setting Transmit: Voice Activity (under Configure » Settings, Audio Input pane).

Mumble transmission settings: voice activity.

The silence below and above sliders can be adjusted, or for certainty of being heard you can change to Continuous or Push To Talk (see above).
