I searched some threads, and found quite a few references. But I would like to re-address this again, since most of what came up from a search was pretty old. What programs do most use these days? Of course I need to be able to measure the low end stuff too. I am leaning towards DSSF3 lite, it looks like just about any decent mic into a mic input would yield decent enough results. Let me know, I want it going by Saturday, if at all possible. I downloaded the 30 day eval, I guess it is fully functional within the 30 days, so I may have some time ti decide with it.
