Dark City Radio Mumble
Mumble is a VOIP platform, similar to Skype but unlike Skype Mumble is free as in speech (and beer) plus its open source and not corporately controlled and owned. This video describes how to download and configure Mumble to connect to the Dark City Radio / Anonnet Mumble server.
DARK CITY MUMBLE SETUP GUIDE
Dark City Radio uses Mumble for realtime, group chat (aka VOIP conferencing). Unlike Skype, Mumble is totally free and open source and based on open standards. It also uses less bandwidth and so works better on slow connections than Skype although it has no support for video. Mumble is available for Linux, Windows, Android, OSX and iOS officially but it should run on pretty much anything with sound hardware and a relatively modern OS.
DOWNLOAD MUMBLE CLIENT
Download the latest stable version of Mumble client for your OS (except Android - see the Google Play store) from here:
After you have installed Mumble, it will run the Mumble Audio Wizard. You can safely click cancel to skip the Audio Wizard. Next you will be presented with the 'Certificate Management' window - just choose 'Automatic certificate creation', click 'Next' then 'Finish'.
The default audio quality in Mumble isn't very good so choose 'Settings' from the Mumble 'Configure' menu and then increase the compression quality from 40 to around 80Kb/s. Also, change the transmission type to 'Push to Talk' then click Apply. Whilst still in the Mumble settings window, choose 'Shortcuts' then click on 'Add'. Change the newly added function to 'Push to talk' then click within the functions shortcut column and assign it to your 'Alt Gr' key by pushing Alt Gr. Click 'Apply' then 'OK'.
Click on the Globe icon or choose Connect from the server menu. In the Mumble Server Connect Window, click 'Add New' and enter the following:
