The right of use for an audio book is the right that gives the rights holder (e.g. author, narrator, publisher) the authority to use, distribute and market the audio book in a certain way. It is a type of licence that allows the rights holder to commercially use and publish the audio book.

The right of use covers various aspects, including:

1. Distribution right: The right to sell, rent or otherwise distribute the audio book, for example in the form of CDs, digital downloads or streaming services.
2. Duplication right: The right to make copies of the audio book in order to distribute or sell them.
3. Performance right: The right to perform the audio book in public, for example at readings or events.
4. Editing right:** The right to edit or adapt the audiobook, for example to offer it in different formats or to adapt it for specific target groups.
5. Translation right: The right to translate the audio book into other languages and to publish it in other countries.

The right of use can be either exclusive or non-exclusive. In the case of an exclusive right of use, the right holder retains exclusive authority to use the audio book and cannot license or grant it to other parties. In the case of a non-exclusive right of use, the right holder can also grant the audio book to other parties for use as long as there is no conflict with pre-existing exclusive rights.

The right of use is an important component of contracts and licensing agreements in the field of audio book publishing. It regulates the rights and obligations of the parties involved and ensures that the audio book is used and marketed appropriately and legally correctly.
