Splasm Software, the creator of Audiobook Builder has announced that they have released an updated version of their audiobook production software for Mac. The software is designed to allow you to take your audio files or audiobook CDs and turn them into audiobooks that are compatible with your iPod.
In addition to placing your audiobooks in the correct place and compiling them into a single file, you are also able to group files into chapters with custom artwork, adjust the quality to your preference, and export completed work directly to the Books section in iTunes.
The application is Universal but requires Mac OS X 10.4 or later. You can pick up a single license for $9.95 or a family pack for just $5 more. If you are interested in grabbing a copy, or just want to learn more about it, you can check out their website here.
