    Mumble Review

    Mumble is a VoIP voice chat application that offers high quality, low latency voice chat. Mumble is optimized for gamers, with an overlay that that shows who is speaking in which channel. Some games have positional audio through Mumble for enhanced game play.

    Favorite Features


    High sound quality with low latency is one of Mumble’s key features. It uses the CELT and Speex codec to improve voice quality as well as to reduce background noise.


    Another key technical feature is Mumble’s encrypted communications. All traffic to and from the Mumble server is encrypted using 256 AES TLS (Transport Layer Security) protocol. This adds a significant layer of security, protecting your voice conversation from local network or Internet eavesdroppers.

    Game Specific

    Mumble integrates with games with an overlay function that shows who is connected to Mumble and what channel they are on. Mumble offers positional audio (also called 3D audio) for some games. Positional audio takes into account your position in a game and modifies the voice chat to simulate distance and position. Notable games that support positional audio include Call of Duty 4, Borderlands, and Battlefield 2.

    Tips for New Users

    Take full advantage of Mumble by enabling positional audio. To do this, go to “Configure” and “Settings” and check the “Advanced” box. Then go to “Plugins” and check the “Link to Game and Transmit Position” box. In the “Audio Output” tab, check “Positional Audio” to fully enable the feature.

    Areas for Improvement

    The Mumble client only supports the Mumble servers. The ability to support multiple chat clients like Ventrilo or Teamspeak would be beneficial to gamers, allowing them to consolidate the number of chat clients they may have installed on their computers.

    While Mumble automatically normalizes the volume of all users, it does not offer a way to modulate the volume of specific users.


    Mumble’s high quality audio, low latency and encrypted communications make it a good general use VoIP application. However, its gaming-specific features, such as in-game overlay and positional audio, are what really set it apart from other VoIP applications. Overall, Mumble is an excellent choice for game server and guild communication, due to its various gaming specific features. If you are not interested in the gaming uses then Skype or Google Voice are better for general use.
