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.
I would really love a version of Calibre that ran in a web browser instead of a desktop app
What about https://github.com/janeczku/calibre-web?
I tried that but you need a Calibre library first, and that requires using Calibre AFAIK
It’s unnecessarily annoying to set up, as the other user pointed out. But it can be set up by itself using https://hub.docker.com/r/linuxserver/calibre-web docker, and used standalone. The only trick is needing an empty database.
Can you explain bit more please. I have calibre-web running, downloaded empty database, added some books in the same folder as database, but nothing is showing up in calibre-web gui. Did I miss something?
You can just create an empty calibre library using the desktop app and then import everything from the web UI.
Calibre-web even links an empty database in their readme so you can do exactly that without the desktop app.
So you want an entirely different app then. The desktop app would have to be completely rewritten.
