Abstract: A system and method are provided wherein a server based music creator is accessible by a client for the creation of composite audio files. In one example the method and system receives, from a remote client computer via a network connection, a play sequence for playing audio segments. Such a play sequence identifies one or more audio segments and associates at least one temporal location in a playback timeline with each audio segment. A composite audio file including each audio segment identified in the play sequence is generated in response to a request from the client computer, such that the composite audio file when played plays each audio segment identified by the play sequence at each audio segment's associated temporal location(s). The composite audio file is then transmitted to the client computer via the network connection.
