This little document is no substitute for the lengthy and detailed FAQ (Frequently Asked Question) lists that you can find elsewhere, e.g. on rtfm.mit.edu and other major archive servers. If you are using a Sun workstation, get the .au files (or compressed version). Then use the OpenWindows "AudioTool" sound player to listen to them. There are demo "play" programs available for Suns too. If all else fails, try "cat latest.au >/dev/audio" :-) If you have a PC that runs Microsoft Windows, equipped with a sound card, get the .wav file; it can be played directly with the media browser. If you have a PC that runs Linux, and have either a sound card (with driver configured in the kernel) or the pc-speaker driver, you can use either the .wav or .au files. It's a bit loud, but you can just "cat latest.au >/dev/audio" or "cat latest.wav >/dev/dsp". Or get a play program (if you find one for X11, esp. with mixer support, let me know!) If you have a Mac, there are several options. One is "Brian's Sound Tools"; another is "Sound Extractor"; I've been told that these both work on the .wav file. SoundExtractor (1.31) can be found on the anon ftp server wuarchive.wustl.edu in /systems/mac/umich.edu/sound/soundutil. You can also use UnZip (1.1) to unzip the lateswav.zip file; I am told the latter is available in many places, e.g. on CompuServe. Tell the Sound Extractor program that the file's frequency is 8 KHz, and make sure you increase the memory (using the GetInfo box) to at least 2.7 Megabytes for the weekend (5 minute) files, and 3.7 Megs for the 7-minute weekday ones. There's also a freeware utility called SoundApp that is supposed to work. These and other audio utilities are locatable by the Archie or xarchie programs (ask your friendly net administrator). I know almost nothing about Macs; this information comes from Robert Smythe who was kind enough to send me the details, and was supplemented by the actual experience of William Grantham. My thanks to both of them. - Pat Murphy http://orangutan.cv.nrao.edu/
