Regardless of the type of DAISY DTB, with the exception of Type 1, all provide a significantly richer reading and/or learning experience than traditional audio cassettes. Not all end users would necessarily be able to use all six types, for example, Types 5 and 6 require a DAISY software player.
Regardless of producer resources available, it is strongly recommended that books not be produced as Type 1 DTBs. There is minimal benefit to the end user (see definitions and explanations above).
