[WriteLog] Using the Sound Card

[Jim Smith]

For a very comprehensive comparison of many sound cards along with test 
results see http://www.pcavtech.com/soundcards/compare/index.htm  These 
are tests of how good they are for audio.  Won't tell you a thing about 
PSK etc.

To find out about and download Rightmark go to http://audio.rightmark.org/

Hope this helps
