I downloaded a “Linux ISO” which came as a series of *.opus files. My iPhone doesn’t recognize them, so I was wondering if you guys might recommend a program to convert them to *.mp3 files.
Ideally a mac or linux based program with a gui. Any suggestions?
I’ll have to check it out. If you want to listen to Audiobooks specifically, I will say that the Open Source app BookPlayer has been fantastic for me.
