Great solution to avoid re-importing a large audiobook library
This app does just what it describes quickly and efficiently. I was able to join together all of my Harry Potter books (individually) in one evening. Though I did not add artwork to each chapter of the book, this app does have that capability!
Also, using the "normal" quality setting the completed file was about half the size of the original, with no discernable difference in audio quality. There are three quality settings, High, Normal and Low. I would assume that the "low" setting would take even less space.
As others have noted, it automatically turns books longer than 13 hours into multiple parts. This is a minor fault in my estimation compared to the 200+ original tracks I was dealing with.
