PYMUMBLE python library


This library is a fork of a fork of a fork (initial from But we will try to make pymumble better. So I consider this fork (the @Azlux one) the current fork alive of pymumble.

The wiki/API explanation is HERE.

The Python 2 version is available in the master branch. It's working! But since we have moved on to Python 3, the Python 2 version will not receive future improvements.

List of applications using pymumble

For a client application example, you can check this list :


  • Compatible with Mumble 1.2.4 and normally 1.2.3 and 1.2.2
  • Support OPUS. Speex is not supported
  • Receive and send audio, get users and channels status
  • Set properties for users (mute, comments, etc.) and go to a specific channel
  • Callback mechanism to react on server events
  • Manage the blobs (images, long comments, etc.)
  • Can send text messages to user and channel
  • Ping statistics

What is missing:

I don't need those features, so if you want one, open an issue and I will work on it.
  • UDP media. Currently it works only in TCP tunneling mode (the standard fallback of Mumble when UDP is not working)
  • basically server management (user creation and registration, ACLs, groups, bans, etc.)
  • Positioning is not managed, but it should be easy to add
  • Audio targets (whisper, etc.) is not managed in outgoing audio, and has very basic support in incoming
  • Probably a lot of other small features


The library is based on the Mumble object, which is basically a thread. When started, it will try to connect to the server and start exchange the connections messages with the server. This thread is in a loop that take care of the pings, send the commands to the server, check for incoming messages including audio and check for audio to be sent. The rate of that loop is controlled by how long it will wait for an incoming message before going further.

You can now check if the thread is alive with mumble_object.isAlive(). The Mumble object will stop itself if it is disconnected from the server. Useful if you need to restart it with a loop are a supervisor.


Check the requirement.txt to know the versions of opuslib and protobuf needed. You need pip3 because it's a Python 3 library (apt-get install python3-pip) to install dependencies (pip3 install -r requirements.txt).


  • @raylu for making pymumble speak into channels
  • @schlarpc for fixes on buffer
