Recording audio books without permission to help the public is regarded as infringement. You need to get permission and pay for uploading other people's novels to the internet for sharing. Copyright Law Article 40 A producer of sound recordings and video recordings who uses other people's works to produce sound recordings and video recordings shall obtain permission from the copyright owner and pay remuneration. Producers of audio and video recordings shall obtain permission from the copyright owner and the copyright owner of the original work and pay remuneration for the adaptation, translation, annotation and arrangement of existing works.
Standards for recording free audio books
If the author stipulates that it is not allowed to reprint without reason, or that it is necessary to pay for reading this book online, or that he has sold the copyright of the radio drama of this book, then it is infringement. However, if none of the above situations exist, then it does not constitute infringement, because you did not record this audio book for profit.
