How do I join multiple mp3 files into one mp3 file?
Hello,
I have multiple mp3 files that I would like to join into one mp3 file and to use it as an audio book. This explains how to do it, but in iTunes 12, I do not see an option called "Part of a Compilation" option.
Is there a way to do it in iTunes without installing a new app?
Thank you.
