In addition to the paragraphs of the document, Biblos in the conversion from text to DAISY considers also the structure of the titles. For large documents or books, it is appropriate to organize the structure of book titles. In the production of DAISY audiobooks, titles up to the sixth level are considered. If the document has higher level titles, they are still transformed into sixth level titles. This is due to a technical limitation of the DAISY format. The structure of the titles allows you to move through the audiobook by means of the titles as well as by moving from paragraph to paragraph.
Other information that is included in a DAISY audiobook is the information in the document properties (File/Properties menu). This is bibliographic information to give the DAISY audiobook also the title, author, copyright, etc..
