Listening to Audio Files

You will be listening to a number of lectures and presentations in audio format.

• the free RealPlayer.

You can download it at home for free here

The version for MAC is here.

• a set of inexpensive earphones with a mini-plug (1/8" plug or jack) at the end. These are the kind used for most Walkman-type cassette players, radios and portable CD players. They cost about $9 at Radio Shack.

If you have a sound card and a good set of speakers on your home computer, you can listen to the Streaming Audio presentations through the speakers.

You may find that you will get better quality sound at home as well by disconnecting your computer speakers and plugging your earphones into the speaker jack. Usually the sound will be clearer, and you won't need much volume.

Volume can be adjusted several ways on a PC: at the speaker (not available if you are using earphones); on the RealPlayer itself, with the slide bar in the center of the Player; and on the MultiMedia icon in the Control Panel (Start-Settings-Control Panel-Multimedia-Audio. Make sure the little box "Show volume control on the taskbar" is checked).

To play a streaming audio file, use your Web browser to connect to the Web page, and click on the link. The browser will automatically bring up the RealPlayer G2, which will take a few seconds to connect to the file, "buffer" a few seconds of sound, and then begin the presentation.
