I recently got my hands on an audiobook with a collection of mp3 files. I like to listen on an iPhone and creating a playlist wasn't working the way I intended.
So, I wanted to explore making an audiobook from the mp3 files.
I tried concatenating all the audiofiles together into a single file. While the files concantenated fine, I was running into trouble with the metadata and the way iTunes was recognizing it.
The following steps seem to fix the issues I faced ... atleast so far!
cd /Volumes/Seagate\ Slim/Books/Option\ B\ Facing\ Adversity,\ Building\ Resilience,\ and\ Finding\ Joy\ by\ Sheryl\ Sandberg
# Requires files to be named correctly. checking a simple `ls`
ls *.mp3
#Concatenate mp3 files
cat *.mp3 > Option-B-full.mp3
# Fix the metadata (iTunes issue?)

ffmpeg -i Option-B-full.mp3 -i Option-B-full.mp3 -map 1 -c copy -map_metadata:s:a 0:s:a Option-B-final.mp3
# Delete the unncessary file
rm Option-B-full.mp3

After the creation of the audibook file, I simply needed to import into itunes and change the Song Info to Audiobook
If everthing worked as intended, you should be able to open up the audiobook using iBooks or the Audible app on the iPhone!
Few audiobooks ran into issues and I tried to solve with this hack!
ffmpeg -i Antifragile-final.mp3 -af volume=1 -vsync 2 Antifragile-final-new.mp3

Other possibilities (?)
