    What is the difference between an audiobook and an audio epub? Does the latter contain both text and audio? Are they synced somehow?

      ePub is basically just a limited HTML page in a zip file (plus a bunch of metadata and CSS styles), and ePub 3 can contain audio and video elements embedded in the text, just like a webpage. With the most basic usage, it would just show up as an audio player in the middle of the text, no sync. But there is also a media overlay thing I haven’t looked much into that looks like it provides sync.
