M4B to MP3 (chapter separation), Converting M4B to multiple MP3s taking into account the M4B chapters Options

[jaime11]

Hello
I have been searching on the forum but haven't found anything. Basicly what I'm looking for is a program that will input a M4B file and output several MP3 files (1 MP3 per chapter in the M4B file).
I have been using Free M4B to MP3 Converter, but unfortunately, all it does is extract a single MP3 from the M4B.

Anyone knows any other programs for this job?

Thank you

Valekhz - I prefer no pre-pending of "Chapter nn" to the beginning of the filename. If you do prepend filenames with chapter numbers, perhaps there could be an option to enable / disable it?

daleybox - If for some reason valekhz does not implement the feature, or if you do not want to wait, there is a pretty easy workaround for you to try...
1) dump the filenames and creation timestamps of the files output by valekhz's m4b-converter into a text file sorted by time created (in Windows, this can be done with "dir /od > dir.txt" - even if they all display the same time to the minute - the OS knows which were created first to the second or better)
2) open this text file in Excel
3) use the "Concatenate" command in Excel to build a DOS command to do the renaming. I've done this for Windows, and I'm sure equivalent simple steps exist for other OS's. For example...

=CONCATENATE("copy """,A6,""" ""Chapter ",C6," - ",A6,"""")
where column A has the old file name, column C has the numbering you want to use

4) copy this row down for all the files, then copy the whole list of commands into a DOS batch file

With this approach, you can then rename or create copies with the new name for all the files at once. This approach is easy and flexible, and would prevent valekhz from then getting additional requests to support things like:
a) users with m4b files with a Preface or Forward or both asking to offset the first chapter by 1 or 2 (or more) files?
b) users with an audio book that is split into multiple m4b's with multiple chapters per m4b asking to offset so that the first file starts with Chapter Y?
c) users who prefer chapters in roman numerals asking for "chapter i" and "Chapter ii" instead of "Chapter 1" and "Chapter 2"
d) users whose audio players sorts / plays the files the order Chapter 1, 10, 11,12.....,19, 2, 20, 21....29, 3, 30, 31 asking to make the chapters two digits wide so they sort in the proper order
e) users who speak language X asking to add options to name files "Kapitel 1" or "Capítula 1" instead of "Chapter 1".
f) users who want the author and/or title added along with or instead the file name / chapter name.

While I prefer that the chapter number is not added to the file name, I can solve that myself. I'm just trying to think about the future in case there are enough people looking to split M4B files that it really matters.
