I spent some time searching (although maybe not very well) for what may be a good mic to use for REW. I've been using the software for some time very successfully with my old style Radio Shack meter. What I want is to start using REW for more than just my sub. I'd like to start using it to help treat my room and understand how the rest of my frequency response is doing. I'd like to see what changes I make look like compared to just what they sound like. So I'm looking for a good mic setup and I of course know about the ECM8000. Is this what I should get, or are there other alternatives that may be better? I'm not looking to spend a bunch of money, but if there is a good reason I should consider something else, please let me know.
