Where Can I Listen On Campus? What Do I Need?

Obviously, you need an audio-equipped computer, the right software, and if you're in an public lab, headphones. The following Labs on campus are equipped for this:

• The IPL (Intro. Programming Lab, 323 Sieg). These PCs all have sound cards, and appropriately configured software; just scroll down to the links below, click and go. All machines have extension audio cables so you don't have to fish around on the back panel, etc. Bring your own headphones. Ordinary "walkman" style headphones work fine. Ask the lab staff which machines to use.
• The Suzallo Computing Resource Center (CRC) (near main entrance to Suzallo). All Macs and two PCs are audio-ready. They have one pair of headphones you can check out at the desk, or bring your own (long cord or long, supple neck preferred). Headphone jacks are usually on the rear of the computers. Scroll down to the links below, click and go.
• OUGL Collab2 (Odegard Undergrad Library). I believe this setup is similar to CRC. Again they only have one set of headphones to lend.

Places NOT to go.

Audio is currently NOT available in the following labs:

• The ACC (Academic Computing Center, Brooklyn & Pacific.)
• The Mac lab in 324 Sieg.

Can I Listen At Home or Work? What Do I Need?

Yes, probably. Obviously, you need an audio-equipped computer, the right software, and if you have a valued roommate, pet, plants, or significant other, headphones.

• Browser: Obviously, you used a brower to read this. You must have a Javascript enabled browser, such as Netscape (version 3.0 or later) or Microsoft Internet Explorer (also version 3.0 or later).
• Audio-equipped computer: Audio is standard on Macs (although not all models have headphone jacks). It's an option on most PC's, although increasingly common; you need a "sound card" of some sort. "Soundblaster" is a popular brand, but there are tons of others.
• Software: To listen to the audio, you must have the RealAudio Player (version 5.0 or later) installed. Click the icon at right for information, including instructions on how to download and install (free!) versions of the software for Mac, PC, and many Unix computers. This is pretty easy to do. They give instructions, also easy, on how to configure your Web browser ("Helpers" menu or the like) so it will automatically run the RealAudio Player when required.
• Modem/Net Connection: To listen to RealAudio, your computer must support a connection speed of at least 14.4 Kbps. Better quality audio is provided for connection speeds of 28.8 Kbps or greater. You specify the connection speed when installing the RealAudio Player, or from within the player. (See the Real Audio pages above for more information).

How Do I Play Through A Lecture?

Go to the list of lectures available and click on the link for the lecture you wish to hear. You will be taken to a page containing controls for the audio and an index of the slides used in the lecture. To listen to the lecture, simply click "Begin"; the slides will change automatically. Buttons are provided to let you Pause the audio, and skip to the next or previous slides. By default, the entire lecture will play in sequence. You also have the option of playing one slide at a time. In this mode, you must use the "Next" and "Previous" buttons to step through the slides manually.

It is recommended that you use the buttons in the upper-left frame to control the slides. Although the RealAudio controls (in the lower- left frame) will work, they can confuse the buttons in the upper frame.

Caution: Save Your Work

• The Javascript that drives the lectures is new and has not yet been proven stable. You should be sure to save all your work before viewing these slides, in case the program crashes your machine before your files are safely saved.
• If the Real Audio player doesn't work, the Real Audio FAQ has tips on getting the RA Player to work on different machines.

Please tell us whether

• this works for you,
• or not,
• whether the page layouts, buttons etc. are sufficiently user friendly, and,
• most important of all, is the online audio content a valuable resource to students in the course.

So please send us mail!

The first lecture from Autumn 1997 was made available on 22 December, 1997. We hope to make additional lectures available at the rate of at least three per week.
