Okay, figured it out!
Well, it's not as simple a process as pressing a convert button on an app, seeing as nobody knows what file format it is, but there is a way nonetheless.
Toast recognizes these files as audio (Mine's toast9 but I'm sure previous versions will be fine). So select the audio CD option, drag the files in there, choose 'save as disk image' and save it onto your desktop or whatever.
Then go to the file that was created, right click and choose 'mount'.
You'll now have an audio CD image mounted, so go to itunes and import these files in a format of your choice.
Done!
