Hey guys, I've looked at several threads, but everyone seems to have a laptop: I don't. So I'm confused on exactly what equipment I need to purchase to get up and running REW, particularly with capability to do waterfall plots. What I do have is a desktop computer with Asus Xonar DS 192khz/24bit soundcard along with an analog Radio Shack sound level meter, that's it. I think that I can use REW now by connecting the RS meter with a really long (stereo rca?) cord, but that will only give me freq response plotting ability to 3khz, correct? Furthermore, I'd really like to run REW with waterfall plots, whether that is advised to be done later with more experience, I don't know. I think that to do waterfall plots I'd need a calibrated mic (from Parts Express?), long XLR cable, and some form of phantom power supply to power it, possibly this Behringer? Am I on the right path? Or am I missing something?
