Creating ringtones in iTunes 12
First of all, I've tried to find this answer, but I can find nothing recent. I have iTunes 12 (12.5.4.42, precisely), an iPhone 4, and Windows 10. I am trying to create a ringtone from a CD that I own. So far, everything I've tried is clearly for some other combination - the closest I was able to come placed an m4r version of the song in "Tones", but ignored my 17 second cut and saved the entire 3-minute-plus song. Can someone please give me step-by step instructions using the latest version of iTunes and my own CD on how I can make a ringtone for my iPhone. Assume I'm an idiot. (I'm 64 years old, so, from a technology aspect, that's probably not too far off.) Thank you!
