so, mp4 = m4a
Audio book and podcast files, which also contain metadata including chapter markers, images, and hyperlinks, can use the extension .m4a, but more commonly use the .m4b extension. An m4a audio file does not "bookmark" (remember the last listening spot) on an iPod, whereas m4b extension files do. Users can rename mp4 m4a file extensions m4b to activate this and faster listen iPod features.
