The audio annotation tool aims to provide a way of attaching textual feedback to specific sections of an audio track (e.g. music composition). This could be used as a learning tool, highlighting important sections, or as a feedback tool for student produced work.
The demo includes a basic audio player with play, pause, stop and seek controls. Comments are listed in the main area underneath, and lines are used to indicate which portions of the track that the comments apply to. Hovering the mouse over either the comment or the line highlights its matching pair.
Clean interface, but requires a Sakai install and not updated since 2006
Professional level tool and compact, but expensive and possible overkill for many situations
Fully featured but complicated
The Audio Annotator will differentiate itself from these in being light-weight and easy to use; focusing on providing contextualised feedback for educational purposes.
