Is there any way to translate or read MAC files on my "PC"?

I am in a class that uses Apple style computers to create
audio files and I can save them and transfer them to my
home computer using I-Tunes, but cannot work with them
or create them on my home IBM-compatible computer.

Does anyone know of a program for a Windows operating system
that simulates the MAC? sort of a translation system or
something?

Apparently some of the audio visual and graphics capabilities
of the MAC are preferred by professional radio, t.v. and movie
folks...what say you?
