  • Also updated external dependency libraries (#159).

New in AAX Audio Converter 1.17.1 (May 13, 2021)

  • Bugfix for 1.17: Mid-level folder for series title was created despite option off (#76).

New in AAX Audio Converter 1.17.0.1 (May 10, 2021)

  • The setup package contains 32 and 64bit variants of FFmpeg. On 64bit systems both variants will be installed. However, the slightly older 32bit version will be used for most books and conversion modes because of its better performance. Only very long books to be converted in single-file mode, which are critical for memory, will make use of 64bit FFmpeg. (#39 2nd part)
  • The Basic Settings receive a new tab page Folder structure for all settings related to output folders, due to another increase in the total number of options.
  • New option in Basic Settings to preselect the behaviour if the output folder for a conversion already exists. (#59)
  • Support for series titles: New option in Basic Settings for books that are member of a series. The hierarchical output folder structure with author and book title layers will receive an additional middle layer for the series title, if the series information can be found in the associated meta data (download via the Audible App required). The book folder name will be amended with the book sequence number in the series. (#62)
  • New option in Basic Settings for a full caption with author, series (if applicable) and book title for the book folder name.
  • New option to add the total number of tracks to the track title tag and the track file name. (#59)
  • This option replaces Add Narrator in the property grid in the main window.
  • The narrator will now exclusively be added with the Meta tags page in the Basic Settings.
  • New optional AAX file date column for the list view in the main window (via Basic Settings). (#59)
  • Conversion order for multiple books is normally defined by the book title, independent of the sorting column. It will become by file date, if the file date column has been selected as the sorting column., but will always be in ascending order.
  • The installer now also offers a personal installation mode, i.e. for the current user only, when installing the program for the first time. The personal mode does not require administrative privileges. (#58)
  • Some additional or enhanced log messages.
  • A number of small enhancements and fixes.

New in AAX Audio Converter 1.16 (Feb 15, 2021)

  • The setup package now contains 32 and 64bit versions of FFmpeg. The installer will select the one matching the operation system. On 64bit systems this allows for very long books to be converted in single-file mode which previously would trigger an out-of-memory exception in 32bit FFmpeg. (#48)
  • New option for less strict version FFmpeg checking to allow user-provided FFmpeg builds where the version string does not fully comply with release builds. (#38)
  • New options for allowing variable and/or reduced bitrate and thus creating smaller output files, at the possible cost of audio quality and slower conversion. (#39)
  • New option to prefer chapter times from embedded AAX meta if using explicit chapter names from the extra JSON file, but where the chapter times are often inaccurate.
  • New customization options for individual assignment of book author and narrator to the four predefined performer tags in meta data.
  • The Basic Settings options are spread across four tab pages now, due to the additional options introduced in this release.
  • The main window has been fitted with a little performance monitor which is active during conversion, in addition to the existing progress bars and status report. Two new small bars indicate the number of FFmpeg process currently running and the relative CPU load.
  • Better error detection and reporting if FFmpeg aborts the conversion.
  • More efficient parallelization in split-chapter mode for books with long chapters.
  • Fixed retrieval of the activation code from Audible Manager which did not work on some 64bit systems.
  • Fixed sorting order for multipart books with more than 9 parts, both in the list view in the main window and during conversion. (#57)
  • Meta data previously still handled by the TagLibSharp library has now been completely replaced with ATL.net. TagLibSharp is no longer used.
  • Some additional or enhanced log messages.
  • A number of small fixes.

New in AAX Audio Converter 1.15.3 (Nov 23, 2020)

  • Bugfix in ATL.net: “Quicktime” chapters, one of the two chapter variants for MPEG4 (M4A/M4B), came out unreadable or with missing or incomplete chapter titles (#37). The bug was related to the new ATL.net buffered mode, introduced in ATL.net 3.13, and used by AAX Audio Converter in versions 1.15.1 and 1.15.2. This has been fixed in ATL.net 3.14.

New in AAX Audio Converter 1.15.2 (Nov 6, 2020)

  • Bugfix: In version 1.15 and 1.15.1, conversion of only a subset of a multipart book could erroneously encounter temporary chapters without a name when initializing target directories. This triggered a NullReferenceException. Such chapters will now be ignored at this stage.

New in AAX Audio Converter 1.15.1 (Nov 2, 2020)

  • Bugfix: Version 1.15 erroneously no longer set track duration as meta data for MP3 files, which is expected by some players. Brought back by reverting to FFmpeg for adding MP3 chapter meta data.
  • A new version of ATL.net is used which now adds MP4 chapter meta data in an efficient buffered memory mode, which is faster than working directly with the file on disk as before.
  • Enhancement: Temporary audio files with a track duration of zero will normally be intercepted. Under certain conditions, they can survive, though. They are now handled properly.
