Sure it is, you're simply getting a line-in signal from the output of your cassette player via a cable. Plug one end of the double-male audio cable (preferably purchased, but possibly wired by someone who understands what is going on) into either the "line-out" output of your cassette player, or lacking that, the headphone jack. Plug the other end of the cable into the "line-in" on your computer and you are ready to record. Of course, before you start recording, you need to match the signal levels- that is make sure the output "volume" of the cassette player and the "input volume" so to speak, of your computer match so that the recording will sound good. I would suggest setting the volume of the cassette player at around mid-way (if it goes to 10 set it to 5) and then hit play. Before you begin recording, look at the waveform window of the sound app you are using- the window in which you can see the sound waves as they are digitized. If the waves are not touching the top and bottom of the window, you can record without causing overload distortion, if the wave doesn't fill most of the window, you might want to increase the input level (or the volume of the cassette player) till it does. With a little trial-and error experimentation, you will find the settings that sound best. I haven't used iTunes, so more explicit instructions will have to come from someone else. Good luck (I know it works, I've done it) -- And when they ask me if I speak Rhinoceros I'll say "Of cours-e-rous, don't you?"
