Are you talking about the software published by DL4YHF (http://www.qsl.net/dl4yhf/ ) ? He did a waterfall/spectrum and a receiver from "DC" to 22.5KHz.

Dear OM,
 
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?
