Audio gap

How long until the audiobook?

For every series we cover: how many days passed between each book's first edition and its Audible release. Some publishers put both out the same day; others take months. This is the record of books already out. We do not predict the next date: when the publisher, Amazon or Audible lists one, it shows here with its source.

Not counted (book 5): the audiobook is out, but we have no first-edition date for it from an official page. The series page lists a later reissue or only a year there, which would give a wrong gap.

Audiobooks out, gap not measured

  • The Wandering Inn: 19 audiobooks out, but no first-edition date from an official page for those books (the editions we list are later reissues or have no date).

Sources

How we measure

The gap is the Audible release date minus the date the book first came out in text: the publisher's product page or the Amazon Kindle page for most series, the author's own book page for Dungeon Crawler Carl. Reissue dates (new hardcovers, new paperback or ebook editions) are never used; a book whose first edition we cannot date from an official page is left out and named above. Side stories are not counted. The median is the middle book (the mean of the two middle books, rounded, when the count is even); "audio first" means Audible listed the audiobook before the ebook.

Dates come from the source table behind each series guide, last checked . A next audiobook appears only when our release calendar has a date read on the publisher's, Amazon's or Audible's own page.
