I know you will probably guess that I need help like a noob in this topic, but no. I can set ringtones from the list of defaults, but I want to set my own custom ringtone. Specifically, one I downloaded. Is there a folder I should put the file in? I have the same 26 second file in .wav, .m4a, and .m4r.

You can try the following in the Terminal. Use .m4a format (e.g. myring.m4a). Put it in a shortnamed folder in your home directory. For instance, /Users/yourname/FTring. Triple click to copy/paste these command strings into the Terminal. You will have to change the "yourname" string to your short login name. Ensure that FactTime is not running when you applie the following commands.
In the Terminal:
/usr/libexec/PlistBuddy -c "Set :CustomRingtone /Users/yourname/FTring/ring.m4a" ~/Library/Preferences/com.apple.FaceTime.plist
and to view what you set:
/usr/libexec/PlistBuddy -c "print :CustomRingtone" ~/Library/Preferences/com.apple.FaceTime.plist
Then test.
