AudioRack - 2.7.4

AudioRack is an open-source radio broadcast automation and live assist system for Mac OS X computers. The system is composed of three major components:

1. arserver - faceless (daemon) eight bus audio server
2. AudioRack - User interface
3. ARStudio - NEW Cocoa/Objective-C based user interface
4. database server (MySQL 4.x supported)

Optionally, audio files can reside on a separate file server, making a fourth component.

arserver/AudioRack support eight players which can play any QuickTime supported audio file format or play through from an audio input device. The system also supports a single "playlist" which when automation is enabled, is kept filled with either singly scheduled items (inserts) or items from the most recently scheduled playlist rotation. The playlist will automatically load/unload/play the eight players as if a DJ were operating CD players. This is accomplished through arserver accessing the database server where schedule, rotation and item information is stored along with a logging/history algorithm for picking items. The system also can perform shoutcast stream encoding and mp3, wave or aiff file recording from any of it's output busses or from an input device. Recordings can be set up to start and finish at a specific time as well. Shoutcast streams are automatically updated with the metadata info from the currently playing item. arserver also supports midi machine control for start/stop/skip-back/skip-ahead controls on it's input device players. And a 15 second broadcast delay in included too. For cueing/control room muting, the system supports up to three mute busses and a cue mute bus. arserver was written in c/c++, and the source code is included.
