Setting up Mixxx with Airtime
First, download a copy of Mixxx onto your computer. You can download a free copy by visiting www.mixxx.org . Mixxx can be used with Windows, Mac, Ubuntu and Linux operating systems.
Once you’ve downloaded an appropriate copy of Mixxx, open it on your computer. When you open Mixxx for the first time, you will be prompted to select a folder on your computer containing music. Mixxx will then create a folder there. This folder is where your recordings will be saved, if you choose to record your broadcasts using Mixxx.
In Mixxx, select Options > Preferences from the main menu.
If you are using a Mac, you will find the Mixxx Preferences menu in the Mixxx menu in the top menu bar beside the apple logo, as pictured above.
In the Preferences menu, select Live Broadcasting at the bottom of the list.
Unless you are using custom Airtime hosting, set the server connection type to Icecast 2. In Airtime, find the other connection details by selecting Help > Broadcasting Live > I have broadcasting software > Mixxx.
In Airtime, you will see your custom Connection Details. Copy the details exactly as they appear in the text boxes into the Host, Login, Mount, Port and Password fields in the Mixxx interface.
When you have entered the information, click the Save button at the bottom of the window in Mixxx. With Mixxx 2.0.0, an additional plug-in is required to enable live broadcasting, which is disabled by default in Mixxx. Further instructions are found on the Mixxx wiki: http://mixxx.org/wiki/doku.php/internet_broadcasting#windows . For windows, you will need the LAME libmp3lame binaries.
Once you have installed that plug-in you are ready to begin your live broadcast session in Mixxx. To do this, select Options > Enable Live Broadcasting to go live. You can now start mixing tracks using the Mixx interface.
When you have set up Mixxx correctly and start your DJ session, you will notice
When you have completed your DJing session, use the shortcut CTRL + L to exit the live steam. When Mixxx disconnects from Airtime, your broadcast source will revert to your normal Airtime schedule automatically.
