@decooney, I just bought the MiniDSP mic sold by Dayton and run that into my iMac. Nothing else.
All, I use test tone generators as well as REW. Tone generators are great for finding room resonances, and when I have a deep null, I like to play the center frequency and walk around the room to find the low and high pressure areas. Tone generators are great, but REW gives you so much more useful information! Waterfall plots and impulse graphs are usually more useful than just frequency response curves. I'm also starting to use the REW spectrograph.
This is a test tone generator I like to use. You can select frequency or a musical note (assuming 440 Hz tuning).

This is an SBIR calculator that is very useful in my opinion.

The Amroc calculator has already been mentioned. Here is the link\
