How to get playback speed options for an audiobook that I ripped and imported into iTunes?
I like the option of varying playback speed from normal to 1.5 x normal on my iPad and iPhone. That works fine when listening to Audible books and listening to podcasts. I would love that option when listening to books that have been ripped to the m4a format.
Years ago I would change the file extension from m4a to m4b and that would give me the option of playback speed change on my iPod. Does that option still exist? What if I had ripped to a mp3 file or converted to a mp3 file?
Are their any settings in iTunes that would give the option?
