Well, its really a recording app - and I suppose I could wire things up and patch it through in some kind of monitor configuration... I really don't want to complicate it that much. Ideally I want a mic that is doing the work, and then just touch it up in the rig a bit if necessary. It would probably be handy for something like PSK to notch or adjust bandwidth... I think there are other dedicated DSP apps that are better suited. I haven't really investigated them.
