I'm basically a two channel guy and have been meaning to acoustically treat my room for a while now. I just learned about REW and decided to measure the room before doing anything. I bought a UMIK-1 from MiniDSP and have just started to play around with it. That company is great, by the way. It only took three days to ship the mic from Hong Kong to PA. Anyway, I already have some questions and want to post some links, so I guess this is a good way to get my post count up so I can do so. I look forward to everything that I can learn here. It seems like there are a lot of people here who know REW very well!
