Playing an audio novel requires professional audio equipment such as a microphone, tape recorder, or sound system. You will also need to purchase an audio editing software that is suitable for the style of your audio novel to convert your novel into a format suitable for playback. As for where to publish your work, it depends on which website you want to publish your work to. Some common audio novel publishing platforms included Himalayan PM, Dragonfly PM, Lychee PM, and Netease Cloud Music. You need to register an account on these platforms and submit information related to your work such as the novel content, author name, cover, etc. for the platform to review. After passing the review, your work can be published and played on the platform. I hope this information will be helpful to you.
