An audio novel was different from a radio drama. An audio novel referred to the recording of an audio book to convert the content of the novel into sound so that people could listen to it. Sound novels usually required professional recording equipment to convert the content of the novel into sound and then play it through media such as radio or television. On the other hand, a radio drama referred to the conversion of the content of a novel into a television series or movie, which would be broadcast on radio or television. It didn't require any recording equipment, but could convert the content of the novel into text and broadcast it on radio or television. Although both audio novels and radio dramas were played by converting the content of the novel into sound or text, the way they were presented and played was different, so they were not exactly the same.
