MP3 files will work on either PC or Macintosh computers. You need to have appropriate software installed (it is free and may already be on your computer). There are different ways to play MP3 files.
QuickTime will open the audio and start playing it as it downloads. The files will play for an average of 10 minutes. When the file is finished, you can replay it if you are still connected to the internet.
Some versions of RealPlayer will download the entire audio file to your computer and then you can play it anytime, off line. Since the files are large, it may take a several minutes to download, depending on your connection.
