Convert one or more mp3 files into single mp3/m4a/m4b/mp4 file
Zak allows you to select one or more MP3 files and convert them into a single MP3 or MP4/M4A/M4B file. The primary use for Zak is audio books. Most audio books are distributed in several files, usually one per chapter. Converting these files into a single .m4b allows one to take advantage of the iPod's bookmarking features.
