AppleMacSoft has announced Audiobook Converter for Mac 4.0.1, an OS X El Capitan update to the audiobook conversion tool for the Mac.

Audiobook Converter is designed to convert all kinds of audiobook such as Audible AA, AAX, M4A, and iTunes M4B to popular MP3 and AAC formats so you can listen in the car, or on any device that doesn’t support the audiobook format. You can use it to convert from Audible and iTunes Audiobook to the most popular file formats on your Mac, including MP3, AAC, AC3, AIFF, AU, FLAC, M4A, M4R, and MKA.

Version 4.0.1 makes Audiobook Converter compatible with Mac OS X 10.11 El Capitan and addresses some known issues. Audiobook Converter 4.0.1 requires Mac OS X 10.6 or later and costs US$34.95 for a single user license. A demo is available to order at the product website (www.audiobooktomp3.com/).
