Convert M4B to MP3

I listed to audio books…a lot. I used to commute around 200 miles a day. I then switched to commuting every other day. I did this for a couple of years. The ONLY reason I survived all of that driving was audio books. Even though I now live 15 minutes from the office, I still listen to them. I have an indash MP3 player in my car for this very purpose. I recently acquired a new book and it is in M4B format, which my car won’t read, so I needed to convert it. I looked for anything freely available and I did find one free one with what seems no strings attached. However it will only convert about 2 and a half hours…my files are 16 hours each.

I found that VLC has the ability to open M4B. If you click on file there is an option to:

convert/save

You can then choose your output format, MP3, and save!
