I have a batch of MP3 based books. Some of them divide into files according to book's own structure: chapters and so on. Some of them was just divided into equally lengthened parts.
So. I've bought an iPhone, and I want to convert them all to M4B format. How could I convert them in a batch? I mean how cold I set up a process once, for each book, and then, after couple of weeks, receive totally converted library.
The only able program for such conversion I've found was Audiobook Builder for a Mac. But it is pretty slow and do not support batching in principle.
Solutions for any platform, please.
