Ringtonator provides a easy to use application which "converts" an AAC file into a Ringtone from iTunes' perspective.
The application modifies metatags based on a followup discovery by Cleverboy about what exactly distinguishes a Ringtone from a Song files in iTunes.
In essence, Apple introduced an additional tag-type that identifies a Ringtone. These tags can be modified by Atomic Parsley manually and should provide a relatively future-proof method to convert songs into Ringtones that iTunes recognizes and treats correctly.
It appears, for now, that all Apple did last Friday was require the "stik" atom, before allowing a file to be "recognized" in iTunes as something it is allowed to put onto the iPhone. They really didn't do much else. The reason the file gives the error it does, is simply because it does not have the correct metadata assigned to it. All the hoo-hah over iTunes updates etc, appear to be unjustified. I feel a little silly. I even tried this on Saturday morning, but I didn't think to try stik values 12-15 on 4 separate files as I should have.
Ringtonator is a Mac application, but Atomic Parsley is available for both Mac and Windows.
