What program/software do I need to listen to the audio recordings?

To just listen to the audio recordings, you do not need any program or software, just speakers or a headset.

To download the audio recordings, you will need an unzip program to unzip the file and an mp3 player to play the audio tracks.
If you do not have an unzip program, click here [1] for a free download of WinZip.
If you do not have an mp3 player, click here [2] for a free download of Windows Media Player.
