Abstract:
This thesis describes the Harmony Audio Player, an application for playback and link editing of digital audio documents managed by the Hyperwave Internet server and Web document management system. Harmony is the Unix client and authoring tool for Hyperwave. The Harmony Audio Player supports numerous diverse digital audio formats and was carefully designed to achieve maximum portability between different Unix platforms, which traditionally provide incompatible audio output facilities. A graphical waveform tool with moving cursor reflects the current playback position during audio output. Local audio documents can be uploaded onto the Hyperwave server, in a manner similar to other media types in Harmony. Particularly interesting are the Harmony Audio Player's facilities for editing and following hyperlinks in audio documents -- both source and destination anchor regions can be specified interactively. A stand-alone version of the Audio Player is available for general-purpose multi-platform, multi- format audio playback, such as a helper application for a Web browser.
