Timeliner is a reimplementation of Variations Audio Timeliner as a web application, using the IIIF Presentation API 3.0. As with the original version, developed as a part of the Variations Digital Music Library System, it is an audio annotation and analysis tool for creating and labeling bubble diagrams. These diagrams can be used to navigate music or other audio for detailed study.
In addition to its use as a standalone application, the Timeliner is available as integrated feature within the successor to Variations, Avalon Media System. Avalon users can create new bubble diagrams directly from item pages within their Avalon instance and edit, share and copy timelines across all items in the repository.
Please note that due to standard browser security, audio resources used with Timeliner must be set up for Cross-origin resource sharing (CORS). This is not necessarily the case for many resources on the web, and not all URLs for media files may work.
