Hi LF-ers...

I'm using sometimes DSP Filter by JE3HHT, but you need a very fast computer to run it correctly.

Subject: LF: Computer as DSP audio filter

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?
