OK I think my age is showing now. I have used REW very successfully in the past now I think my brain hurts. when running REW and click find peaks and assign filters should I follow the recommendations and use all of them or concentrate on the low end first? I believe I'm doing it right but who knows. It just seems that I start off with 3 or 4 filters and then it gets away from me and REW wants more and more filters. Trying to get this figured out again. my graphs are a mess afterward. lower but more jagged.:help:
