OpenAudible Documentation

This Audiobook Manager lets you catalog and organize your audiobook collection. It is optimized for Audible users, but can import MP3/M4A/M4B audiobooks as well.

Please respect copyright owners by not distributing files created with OpenAudible.

Quick Start

Here is a quick-start guide to get you going.

  1. Download, install, and launch OpenAudible
  2. Go to Edit > Preferences, and select M4B or MP3 audio output format. M4B encoding is the recommended default setting, but MP3 can be set in the Preferences.
  3. To use a custom directory for your audiobook library, use the File > Manage Libraries to move the library to a new location with a large drive capacity.
  4. Select: Controls > Connect to Audible and log into your Audible account.
  5. Your book list should be loaded, and the option to download and convert them should be displayed.
  6. Click yes, or you can click no to manually download or convert your books.
  7. Downloading and conversion can take a while. You'll need to be patient!
  8. Click on the "Downloading" or "Converting" Library Status lines to see which books are downloading or converting. Click on one to see detailed progress.
  9. To find the converted book files, select one and right-click "Show MP3" or "Show M4B"
  10. Periodically run Controls > Quick Audible Library Sync to update your latest purchases!
  11. Full help is available under the About Menu (or by pressing F1) which shows this document!


Install the version for your platform. OpenAudible for Windows and Mac is a digitally signed application.
You may be prompted that the application may not be safe to run; however, you can safely run it if the certificate shows it as valid.

Choose one of the installers from the official download page. OpenAudible supports 64-bit x86_64/AMD64 and Apple Intel/Silicon architectures.

Note: Mac users may need to open the OpenAudible.dmg file by selecting it in Finder and Control-Clicking the application, then select Open (right-click "Open"). You may also need to update your GateKeeper settings to allow apps not from the App Store to run.

Connecting to Audible

Note > Before jumping in, it is a good idea to set up your main Preferences to set the audio output format and other settings.

Getting your books from Audible is pretty simple. Books can be automatically downloaded and converted to a format that works with any audio player.

Initial Connect to Audible

OpenAudible can read and import your library automatically. OpenAudible uses the Amazon/Audible web browser to connect and never saves your username or password. However, a credentials token is saved so that you can stay connected until you decide to Controls > Log Out of Audible.

  1. Select Controls > Connect to Audible.
  2. Choose your audible region that you normally log into. If you're using an old Audible username account that isn't an email address, check the box. Then click OK.
  3. Log in using the web browser, answering any CAPTCHAs, and verifying account with 2-factor email or text message to prove your humanity.

Once logged in to your audible account in the browser, your books will be loaded and shown in the OpenAudible window. The OpenAudible Library status should change to Connected: Yes.

After a library scan, you'll be asked if you want to download and convert your books. If you click No, you can manually select books to download or convert.

Syncing your Library

When you purchase new audiobooks, you can select Controls > Quick Audible Library Sync which will add any newly added books.

You can select Controls > Full Audible Library Sync to get all of your books and update any metadata that may have changed, such as ratings or book descriptions.

Downloading Audible Books

Books that were not automatically downloaded can be downloaded by selecting them selecting Action > Download.

Downloading a book can take several minutes. To see the progress, click on the "Library Status:Downloads" panel item to see books currently downloading or waiting to be downloaded. Select a book and look at the "State" under the Book Info panel to see its download or conversion state.

Once a book is downloaded, it can be manually or automatically converted to the audio format of your choice.

Some books include a PDF companion file. If available, those will be downloaded when the audio is downloaded.

Converting Audible Files

Convert your Audible AAX files to M4B or MP3 easily by selecting a book and selecting Action > Convert to ... or convert them all by Controls > Convert All to ... .

We recommend using M4B for most use cases, as converting to mp3 will always add some loss and may increase the file size. But if you have an audio player that doesn't support M4B files, you can choose to convert your audiobook files to MP3.

Note: To convert your books to MP3 instead of the default M4B format, set the Audio Output Format to MP3 in the Preferences, which can be accessed by clicking on the icon in the upper right or by selecting Edit > Preferences.

Audible files are kept in the AAX directory. Once converted, you may decide to delete the AAX files to save space.


You can set the conversion output format, choose a language, or choose a color theme.

preferences dialog

Use Edit > Preferences view and change the application preferences.

Color Schemes Include:

You can also choose a language. We currently support: ar,de,es,fr,hi,ru

To set the Library Location, use Manage Libraries.

Manage Libraries

The File > Manage Libraries menu brings up a dialog where you can set or change your Library Directory, where your audiobook files (MP3, M4B, AAX, JPG) will be saved.

If you have a larger disk drive than your OS drive, you may want to change the library location, as audiobooks can take up a lot of file space. You can also use a network share, if you don't mind a little less performance.

manage libraries

The top of the dialog has a Library: which lists your known OpenAudible libraries. The buttons below are active if they can be used to move, copy, activate or delete a library.

Select a library and the information will fill in with the Path, Info, and Size.

Before using any of these, read the confirmation dialogs carefully before continuing. Make sure none of the audiobook files are in use by another application.

Library Options

All of these options include a dialog message showing what will be done with an option whether to proceed. Use care, and always back up your library manually before attempting a big change.

Main Window

From left to right, top to bottom, the OpenAudible main window has a search bar, version/news indicator, Library Status Panel, Audiobook Info, Summary Panel, and Audiobook table that lists your books.

main window



The search bar at the top right of the app allows you to filter books by text or pre-defined filters. Type CTRL-F (Command-F) to activate the search. Start typing and all books that match will be shown. Use Escape to clear the search results and display all books.

Pro tips:

To the right, a line of text displays the current version, and if there are any upgrades or news available.

Predefined Search Filters

The Search Combo also has a list of predefined search filters that can be helpful finding groups of books matching a characteristic.

  • AAX Files: Show all books that have an associated AAX file.
  • MP3 Files: Show all books that have an associated MP3 file.
  • M4B Files: Show all books that have an associated M4B file.
  • PDFs: Show all books that have a PDF file or link to one.
  • AYCE: Show books that are "all you can eat" included with your membership.
  • Ignored: Books that have been marked (by you!) to be ignored. They can be unignored with the Action menu.
  • Missing Links: These books have no converted audio files and no link to download. These may need to be deleted.
  • To Convert: Books that have an AAX file that can be converted into MP3 or M4B.
  • To Download: Books that don't have a converted audio format that could be downloaded.
  • Downloading: Books that are in the download queue or are actively downloading.
  • Converting: Books that are in the convert queue or are actively converting.
  • Possible Duplicates: Show books that have the same ASIN, Product ID, or Title. These could be unwanted duplicates.

Library Status

This shows your library statistics.

These statistics are updated periodically and reflect our best attempt at determining these values. For instance, Hours depends on being able to determine a book's duration.

Note: Click on any blue label to see books that match that filter. For instance, click 'Downloading' to see all books that are being downloaded or queued for downloading.

Audiobook Info

Information about a selected book is displayed here. This info is collected from web or meta tags and cannot (at this time) be edited.

The blue labels on the left side can be clicked on to filter books by title, author, narrator, genre, or publisher.

Clicking the blue text on the right side will open the browser to display the Audible page for the title, author, narrator, genre, or publisher.

The information for each data element is self-explanatory. The State field shows any errors or tasks that can be performed. The ID contains the Product_ID/ASIN.

State information can display the following:

Audiobook Table

The list of your books. Click on a book and the book's information will populate into the "Audiobook Info" panel.

An icon on the left side shows the book's status. The following status icons are available:

Status Green Audiobook is available as an MP3 or M4B audiobook file
Status White Audiobook is ready to download
Status Red Audiobook is missing and has no download link. May need to be deleted. This can happen if you import a book and delete the audio file.
Status AAX Audiobook is ready to be converted from AAX to MP3 or M4B
Status Converting Audiobook is being converted to MP3 or M4B. Click on the book to see the progress in the Audiobook Info Panel.
Status Convert Queue Audiobook is in the conversion queue and is scheduled to be converted.
Status downloading Audiobook is being downloaded. Click on the book to see the progress in the Audiobook Info Panel.
Status downloading_queue Audiobook is in the download queue and is scheduled to be downloaded.
Status audiobook_dir Audiobook is a directory containing one or more audiobook files.
Status audiobook_dir_err Audiobook is a directory that is no longer found on disk.

To sort by a column, click the column header once. To sort in the reverse direction, click it again. Click it a 3rd time to go back to default sorting.

Table columns can be rearranged by clicking the header and dragging to a new location.

Table columns can also be disabled, and some additional columns can be enabled by right-clicking and selecting the submenu called 'Table Settings'. To restore the Book Table to default, select 'Reset Table' from the 'Table Settings' submenu.



Simple Copy and Paste

You can select one or more books in the Book Table and select Edit > Copy Edit > and paste it into any document (Google sheets, Excel, or text document).

Only the items in the table will be copied.

Exporting All Audiobook Data

To export a list of your books (not the audiobooks files), select File > Export Book List and set the "Save as Type:" to either json, csv, xlsx. OpenAudible also keeps an updated "books.json" that can be used in read-only mode by other applications.

Your audible library can be exported as a web page, json, .csv, or .xlst (Excel/Numbers) file from the File menu, so you'll have a list of all your books.

Exporting Web Page

This optional feature lets you export your books as a web page. if you want to access your books on your own personal web server. Please ensure that you password-protect this file to prevent the unauthorized distribution of copyrighted works.

This feature is likely to change in the future. It creates a rather large copy of all the converted books, doubling the amount of space needed to save your books.

Back Up OpenAudible Library

To backup or export your entire OpenAudible library to another directory location, use the Copy Library button under the File > Manage Libraries menu.

This can be used to save a backup copy to a cloud disk, external drive, or when you want to move your library to a new directory. See more at: Manage Libraries.


Importing is recommended when you can't download and import books directly from Audible using the Library Sync features.

Use the File > Import Books menu, or drag and drop "whole book audio files" of type MP3, M4B, M4A, directories, ZIP, AA or AAX files onto the Library Status Panel of the OpenAudible application.

Zip files are a special case, and somewhat experimental. The idea is you can download zip files from Librivox and drag them onto OpenAudible. If the zip file contains at least one audio file and an optional image file, the book will be automatically "joined". The audio files need to be alphabetically sorted to join correctly. If you experience problems, you may need to unzip the files and manually add them. This is an experimental feature.

Directories are similarly handled; we assume a directory needs to be "joined".

Note: Only import full books and not books split into multiple parts. To import a book that contains multiple audio files, please see Joining Files in the next section, or import from a zip file.

Import from URL is a feature that lets you download a book from a web URL and add it directly into your library. If you send a link to an HTML page, we will look for a zip file or audio file and import that. Please use with care, as this is an experimental feature. You don't want to accidentally add a bunch of audio files that aren't books to your library.

Splitting & Joining Audiobooks

OpenAudible prefers 1 audio file per audiobook. It's how our software was designed. However, many people prefer an audiobook split by chapter.

It is also possible to download a book in a zip file that may contain multiple parts that can be combined to create a whole book in a single audio file. See Importing zip files above.

Join Audio Files

Some audiobooks contain multiple audio files. To import these into your library, or to simply have a single audio file for each book, you can use the Join Audio Files command, under the File Menu. To join audio files into a single mp3 file, choose "Join Audio Files" from the File menu. Select a directory that contains all the audio files. If an image file is present, it will be used as the cover art. Audio files in the directory will be sorted alphabetically and joined. Next, select a destination directory for the output file. It can be the OpenAudible's "temp" directory, or anywhere. After joining, you will be asked if you want to import (move) the file to your OpenAudible library.

Pro tip: You can drag and drop one or more book directories onto OpenAudible to import books into your library as a single mp3 or m4b file.
Each directory should contain one audiobook, with one or more audio files and 1 optional JPG or PNG cover image file. All parts of the book must be in the correct order alphabetically, so be careful if you have a book that is chapter 1, chapter 2... chapter 11, as those may sort chapter 11 after chapter 1.

Split By Chapter

We do not recommend splitting books in most cases. Instead, use a good audiobook program that can handle chapter metadata and keep track of where you are listening across all your devices. However, some players have limited storage or may not manage playback position well. In those rare cases, splitting may be useful.

To split a book by chapter:

  1. Select one or more books in the OpenAudible book table and select Action > Split by Chapter.

    If you selected one book, it will be shown in the file explorer after splitting. If you selected multiple books to split, a report will show the results of the split.

    As of OpenAudible 3.9, split books will be added directly to your library and show with a green 'folder' icon.

  2. To split Select a file not in your OpenAudible library, select File > Split by Chapter and select any MP3 file you wish to split.
  3. Select a destination directory location for the split book parts
  4. If chapter data is present, the audiobook will be split into multiple chapters, leaving the original file untouched.

Ignored Books

Some books in your library might be lame. Maybe you'd rather not download them. For those books, just select them and Action > Ignore Book to add it to the list of books to be ignored.

Restore Ignored Books

  1. Click on the "Ignored:" Library Status in the upper-left of the main window
  2. Your ignored books will be shown. Select one or more books and right-click or Action > Unignore Book(s) to remove the books from the ignored list.

Read Status

Each book can have a "read status" which can be set from the Action > Set Read Status.

Options are:

You can also set a custom value by selecting the Get Info menu and editing the value in the Read Status field.

Chapter Names

Chapter names are available for some books. When they are available, they will be added to the output file and available in audiobook players that recognize standard chapter metadata.

If you have converted files created before version 3.1, your output books may be missing chapter names. To add chapter names to these books, you'll need to perform a Controls > Full Audible Library Sync, then manually delete the mp3/m4b files, select Control > Rescan Files, then re-encode the files.

File Names

Currently, file naming is handled by OpenAudible. You can rename the filename under the Controls > Rename Book.

A future version should allow you to customize the filename format by author, series, genre, etc., but this commonly requested feature is still "in progress."

Unsupported Books

AAXC files that have been downloaded from Android or Kindle are not supported. (However, these can be downloaded using OpenAudible.)

To check if your book is downloadable, open a regular web browser, click on your library, and search for the name of the book. If there is a "Download" button, it should be available to download. Without a download button, there is usually an explanation of why it can't be downloaded.

If you have an AAX file that won't convert, delete or move the file and re-download it using OpenAudible.

License and Demo Mode

OpenAudible is shareware and can be tried before buying. To use all the features, a low-cost license is required.

A license can be purchased from or from within the application About > Purchase.... One license can be used on up to 5 personal audible accounts. Not for commercial use. Use only for archiving and backing up your audiobook purchases.

Activating the license is done through the About > License... menu. More details about the license and order lookup are available at

If you exceed the limit of five audible accounts on one license, your license will not allow you to work with books from additional Audible accounts.

A license entitles you to one year of free updates. After 1 year, an upgrade can be purchased through the application that will give you another year of software updates. But you can always use a version of the software that was created before the annual expiration date.
