Do audio novels need the permission of the original author?

Normally, audio novels needed the permission of the original author. This was because audio novels were a type of work that converted literary works into audio forms. The focus of copyright protection was on the original content of the original work rather than the form of sound interpretation. If an audio novel was created by an unauthorized original author, the creator of the audio novel might face the risk of copyright violation. In this case, the producer needed to obtain the original author's permission or pay the copyright fee to produce and sell the audio novel. Of course, some original authors might negotiate with the creators to grant them authorization or partial authorization to protect their creative rights. However, even if they were authorized, the creator still had to abide by the relevant rules and terms of the original author and not violate the copyright.
