Can I make one comment here.  I find the fact that some soundcard programs are
available in a DOS flavour only is a source of frustration.  The reason is I
run Windows NT on my main box, and a lot of these programs fail miserably under
NT.  Linux, well that at least has a fighting chance, provided the processing
requirements are modest (it's only a 486).
