Structured Audio

Structured audio refers to digital audio content that has been encoded with hierarchical markers and metadata, allowing non-sequential access to specific segments such as chapters, sections, paragraphs, and phrases. Unlike linear audio recordings (such as traditional audio tapes), structured audio enables users to navigate directly to any part of the content, skip between structural levels, search for specific sections, and set bookmarks. This approach is fundamental to the DAISY digital talking book standard, which codes audio at multiple levels of detail to support rapid, non-serial access to information for blind and visually impaired readers.
