Mixxx 1.9.0 or later includes a live streaming client which, like Airtime, is compatible with the Icecast and SHOUTcast media servers. Mixxx users can also record a show, and then upload it through the Airtime web interface on a local or remote server for collaborative or user-generated broadcasts. For example, for a GNU/Linux client machine, a nightly rsync download of new media in the archive would guard against network problems at playout time potentially disrupting a broadcast at a remote studio. The method that you implement would depend on the operating system of your desktop client machines, and whether they were on the same local network as the Airtime server, or remote.įor performance and redundancy reasons it is advisable to cache files required for a particular show on the client machine where Mixxx is installed. The Airtime storage archive can be exported like any other file server share. Therefore it is possible to manage the station's storage archive remotely and collaboratively through Airtime, while using Mixxx as the live playout client in multiple, remote studios. Individual files from the Airtime storage server can then be added to either of Mixxx's live players with a right-click on the filename, or by using the appropriate hardware buttons on a control surface. If the filesystem path has been configured correctly, the metadata for the files in the Airtime storage server will be displayed in the main window of the Mixxx interface. Enabling write access directly to the storage server is not recommended, as this would allow desktop users to delete files which might be needed for playout later. You may need to adjust file and directory permissions so that the storage directory has read access from the desktop user account. (This location can also be configured after installation by clicking Options, Preferences, then Library in the main Mixxx menu). If you make the Airtime server's storage directory /srv/airtime/stor/ accessible to a desktop machine as a read-only location, Mixxx will accept that location as its default music library when starting up for the first time. Select devices other than the ALSA default of hw:0,0 for at least the Master and Headphones outputs. The solution is to configure Mixxx to use additional sound cards by clicking Options, Preferences, then Sound Hardware in the main Mixxx menu. Otherwise, you may see an error message that Mixxx cannot access the sound device. If you wish to use Airtime and Mixxx on the same machine, you will need two or more sound cards, as each program requires exclusive access to the sound hardware. A control surface might replace or augment an analogue mixer in your studio, depending on your live mixing and playout requirements. Mixxx supports a wide variety of popular hardware control surfaces, which can be connected to your computer using a USB cable. Although Mixxx has many features designed for dance music DJs that require beat matching and pitch independent time stretching, the program can be used for any kind of manually triggered broadcast playout, including live speech shows such as news or current affairs. Installed on a desktop or laptop computer, Mixxx complements your Airtime server to provide a complete system for both live and scheduled broadcasting. Mixxx is a cross-platform Open Source application for DJs, available from
