inAudible is a Windows application for transforming Audible audiobooks to the standard file format that can be opened by any media player such as Winamp. There are flexible conversion settings.

How to use

The first step is to import Audible files in the AA, AAX or ADH format. After that users can select the output format from the drop-down menu. Available options include AAC, MP3 and WAV. The final bitrate is adjustable as well. It is possible to encode the resulting track with a variable quality to reduce the output filesize.

The minimum silence duration for automatically splitting the audiobook into chapters is customizable. Checkboxes for removing all tags, normalizing the volume, creating a CUE file and embedding a cover image into the audio track are provided. The Audio Editor module allows you to manually remove advertisements and trim the track.

Metadata

Users can include information about the author, title, year, narrator, album, publisher and genre into the resulting file. Instruments for automatically filling all text fields based on an online database are available as well.
