To everyone who scratched their heads over my questions... SORRY...

Aaaaahhhhh... "MY BAD" ?

Just played with REW to see if my laptop's soundcard would work, since it has line in and out. My ignorance of REW was quickly evident.

Before joining here I skimmed the instructions of another analysis program. I believe it discussed the technician manually playing prerecorded test and reference tones, while the program displayed the acoustic effects on these tones.

I did not understand that REW is a fully automated system that generates its own test tones, and marches itself thru the analysis (pretty much like my Pioneer receiver, but better). I was only expecting REW to provide real-time analysis, so I could figure out adjustments for system acoustics.

I now understand the REW has to be connected to a processor so it can generate its own test tones, as needed.

Both very cool and more complicated than I was expecting... g'night... Don

p.s... the connections photos, I spoke of previously, are in the REW online instructions files
