Abstract: A data file delivery system is provided having, at a head end, a production subsystem which communicates with a delivery subsystem via a local area network, ISDN connection, and the like. The delivery subsystem communicates with an affiliate subsystem, at a tail end, via a satellite link, ISDN link and the like. The production subsystem enables a producer to create audio events which represent sequences of audio which are played to completion before another audio event occurs. Audio events are stored as audio files. Each audio event may include one or more of an audio sequence, text information, delivery instructions, and an attribute list having contact closure information and the like. Optionally, multiple audio events may be assembled at the production subsystem to form a play list. The audio files are transferred to the delivery subsystem. The delivery subsystem places the audio files in delivery envelopes and transmits the envelopes to the affiliate terminals.
