I wanted to put a book on tape onto my iPod, so I connected my PowerBook G4 to my cassette deck and was able to import a tape's worth onto my hard drive using Audacity. I then exported as an AIFF. So far so good. The quality seems fine. I can replay it using Quicktime. The problem is this--I thought I could just drag the AIFF file into the iTunes library and then convert to AAC to copy to the iPod. iTunes will not show the file in the library, though. I also tried File->Add to Library, but that does not bring the file into iTunes either. Each time, the green plus sign shows up as if it's working, but it never appears. OS X 10.3.9, iTunes 4.7.1, 1Gig RAM. Is there some conversion step that I am missing here?
