MarkAble is designed for audiobook listeners who own an Apple iPod, or who use iTunes to listen to such books. Or podcast listeners wanting to be able to combine and bookmark their saved files. Audiobook files bought from the iTunes Music Store or from Audible.com are ‘bookmarking’ - that is, the iPod (or iTunes) remembers the point of the book where you were up to, and resumes from there when you start listening again. This, of course, is vital. However, there are many other sources of audiobooks. Such books may be in a variety of different formats such as MP3 files (for example, from podcasts, www.audiobooksforfree.com or www.telltaleweekly.com), or audio CDs or tapes you may have bought. Getting these into a format which is bookmarking like the books from Audible.com is a tedious and difficult process - or at least, it has been up until now.
