Turn Audio Files Into
Polished Audiobooks

Great with online audiobook downloadsFor reasons I've not understood, some of the otherwise great online sources for audiobooks supply them in multiple small files and troublesome formats. That makes playing them through Overcast a nuisance. This app not only combines them into a standard audiobook format with all the bells and whistles, it does so with smooth, flexible and powerful controls and frequent updates. I cannot recommend this more highly. I only wish I could give it six stars rather than five.

SuperbFive stars isn't enough for AudioBo - or for the developer behind it.

The app itself is exactly what Mac users have needed for years: a proper, native audiobook builder that actually does the job right. Clean interface, smart defaults, and loads of options to make it work in the way you want. Converting and updating my audiobook library was a joy.

But what's really set AudioBo apart for me is the developer. I reported several bugs and had a personal, thoughtful response within hours - not a boilerplate acknowledgement, an actual reply. The fixes followed shortly after. I've also seen feature requests I raised turn up in updates within days. This isn't a developer who shipped and vanished; this is someone who clearly cares about making their app genuinely excellent.

This is an app and a developer well worth paying for.

Finally Fixed My Messy Audiobook LibraryI've been struggling with a messy audiobook library for a long time. Most of my books were split into multiple parts or stuck as long MP3 files with no chapters. I tried command line tools like ffmpeg, but it quickly became frustrating and error-prone. AudioBo solved this cleanly. I was able to take split M4B files and merge them into a single file with proper chapters. Even better, it can match real chapter data to the audiobook and rebuild the structure automatically. That alone saved me hours of manual work. It also handles long audiobooks without splitting them, which is something a lot of other tools fail at. What I like most is that it turns a messy library into a clean, consistent system: one book, one file, proper chapters, and everything works perfectly in Audiobookshelf. It's simple, fast, and actually built for audiobook workflows instead of general audio conversion. If you care about organizing your audiobook collection properly, this tool is worth it.

An Outstanding App to Build Audiobooks!I have used a couple of apps in the past, which worked, but they were slow and lacked the functionality of AudioBo. One of the features most appreciated is the ability to retrieve and modify meta data for books. I also truly appreciate the speed for the process of building the books. I used AudioBo to build a large book for a guitar course and it did an outstanding job. I also appreciate that the developer has made the app accessible for users with various disabilities. I highly recommend AudioBo.

Totally worth itI really like how it instantly turn my messy audio files into chaptered audiobooks that remember my playback position which is great for organizing my library.

YES!!As others have said, this is EXACTLY what I've been waiting for! This makes converting files so much easier: a Calibre for audiobooks. Thank you for not only creating a wonderful app, but making it a one-time purchase rather than a subscription (I wouldn't have bought it otherwise). A very useful tool at a fair price! A future feature request would be to allow for a multiple process queue so several books could be batch converted unattended.

Outstanding!An amazing app with the function to search for chapter divisions and apply to files with messed up or no divisions to start with. As long as the total duration of the original file matches versions available on sites like Audible, the app does the rest with the click of a button. Perfect for transferring old recorded books from CDs or single MP3 files into audiobooks with chapters.

Best app to create AudiobooksBest app to create audiobooks wihtout any limitations. Very easy to use and far ahead of any competitors.

Great M4B Multi-toolDoes what's required, without unnecessary complication... Very responsive developer, pushing frequent useful updates.

Excellent, reliable audiobook creatorI was a little worried about giving this app a go since there weren't that many reviews, but I'm so glad I took a chance on it! It's a workhorse! It is intuitively built and thus very easy to use, and can handle very large audiobooks and small audiobooks alike. It's surprisingly speedy and the options for audio quality are excellent. This is the audiobook creator to use, and well worth the money.

Works WellShout to Vlad, after audiobookbinder stopped working I was in desperate search of a new binder. Everything works well and is quick and smooth, I really appreciate that the dev is active and constantly improving.

Very nice audiobook toolI bought the app today and tested it after using AudioBookBinder for years. It is truly fantastic — you can enter much more information than with the competition, and when I had questions, the developer replied within minutes. Top-notch support, top-tier app; the developer is also very open to ideas for future features.

Incredible ToolThis tool is absolutely incredible. I don't mind using CLI tools for tasks, but the convenience and flexibility of this app, including the ability to simply update M4B metadata is incredible.

Great Audiobook authoring toolOnce in a while I spend a bit of time sorting out my old audiobooks in MP3 format and AudioCDs and converting them into proper audiobook files. I've normally used Audiobook Builder (ABB) but that hasn't been updated in a while and even though it still works, it looks very dated. AudioBo got a lot of inspiration from ABB but has a modern look and feel and some nice comfort features.

Best Audiobook ToolI tried quite a few different audiobook tools/converters, and this is easily the best. The recommendation you'll see most on Reddit and the like is AudiobookBuilder, but it has very short length limits that force you to output multiple part files. AudioBo is far and away the better option.

Unbelievably GoodKudos to the developer - he crushed it. The app has a simple interface, intuitive UX, and powerful features like matching source files to books, automatically structuring the book properly, updating the cover, and so much more. I used Audiobook Builder 2 for years, and this is easily 10x better.
