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,

Thank you so much for writing this script! You are doing great work! I have been looking for a way to do this for some time, and I'm thrilled to see that someone with the right skills has taken an interest. I didn't visit the site for a couple weeks - and it looks like I missed alot!

While it is *almost* working for my m4b files, unfortunately, it is not quite there just yet.

For background...When I run the original script (from Dec 4), it must be close to being able to parse the chapters, because as it works, I can see the chapter names scrolling by, but it only creates a single mp3 file. I suspect the problem might be related to the characters in the chapter names, because as it works, I can see that some of the characters (both western, but non-English characters, like ", ǐ, ǚ, , , " as well as Asian, like "你好") look corrupted.

When I ran the new script from Dec 10 (I think I'm following the instructions right), I simply get an error message "This application has failed to start because MSVCP100.dll was not found. Reinstalling the application may fix this problem." The first few letters do suggest that the dll you compiled may be creating a need for other components of Microsoft Visual Studio, so I downloaded and installed it. Now, it does run, and does create multiple mp3's from one m4b. However, it creates far fewer mp3s than there are chapters. I also notice that some of the mp3 file names are not the same as the m4b chapter names...again, I suspect it is related to non-English characters. Do you think there is any way to get chapter names / file names using other character sets? I will send you a couple of my m4B files as a samples via email in the hope that you are willing to give it a try smile.gif

Again - I am so happy that you have both the knowledge to deal with this topic and the interest to do so. Thank you so much!
