By the way... Thanks Alberto for a really easy QRSS viewing program! Argo
has worked no trouble on every PC i've tried. More than can be said for some
of the others....

Dave,
    thanks. If the other program you are referring to is Spectran, well, 
Spectran has
a much thougher job to do, as it pretends to output the filtered audio signal 
in full duplex,
and to bypass the entire process of digitization when you press the PassThrough 
button.
In addition, measures have to be taken to insure that what you hear is only the 
processed
signal, and not a mixture with the input signal.
This implies a complete control of the soundcard mixer. Unfortunately not all 
the mixer
implementations are created equal, some have the selectors, others the 
switches, some
have 'Select' controls, others have the opposite, the 'Mute' controls.... etc. 
etc.
All this has the consequence that, at least in its present stage, Spectran 
works on many
sound cards, but not on some models, notably the SB PCI128 family.
But, albeit very slowly, we are trying to sort out all of this mess....
In Argo, things are much simpler. When you press the 'Select Input' choice, all 
what
Argo does is to present you the Windows mixer panel, and then it's up to you to 
do the
correct choice... unfortunately this cannot be done in Spectran...
