I have been told there exists a computer program that not only presents received
signals as a waterfall display but can also make one of the signals being heard
as audio via the computer speakers. In that way the computer can act as a DSP
audio filter, perhaps even for normal speed CW provided an appropriate bandwidth
is selected. Anyone know more about this program?

Dick,
You probably mean the latest version of Spectran which has all of the usual
waterfall stuff, plus a very easy to use CW filter. The frequency display
shows the incoming signal, and also the edges of the filter which can be
adjusted simply by left or right clicking the mouse. You can easily separate
the wanted and interfering signal this way.
