Can anyone point me to an audio DSP program that uses your computer soundcard and speakers?

Not sure what kind of digital signal processing you want to do, but you might try http://www.muenster.de/~welp/sb.htm for a long list of audio DSP programs, from RTTY and SSTV to audio analyzers and filters.

Good luck and 73, Rich

Hello....I downloaded a copy of the demo DSP program from Silcon Pixels a while back called ChromaSound and it seems to be a real neat program to use!!  It was fun to play with but I got a newer rig with good DSP so never used this program to buy the full registered version but I think you would find this site and application that meets what you are looking for.

ChromaSOUND is a general-purpose audio DSP program, that provides the following features :

SSB "denoise", for reducing static on SSB signals
Automatic notch filter, for removing tones, heterodynes, and those pesky carriers
Bandpass, Low-Pass, High-Pass, and Band-stop (manual notch) filters
User-defined filters, using the built-in Graphical Filter Designer. Just drag your filter from the design window to an empty button!
Selection of pre-defined filters,
AGC, or Automatic Gain Control for operation under varying conditions

The website address below (pick Amatuer Radio then the ChromaSound DSP page):

I tried ChromaSound and it had so much echo that it was unuseable for me. I might have messed up the settings though.
