I would like to think the 'before' has an element of truth to it, but they aren't in the deep end of the pool in the sense that professional room doctors aren't gonna pull out their iPhone, run Aud, and be like: "yup, all good here."
Nothing will replace a good program like REW. That said, when I get the new speakers and REW going, I'll have a point of comparison between with Aud, without Aud, and see them much better resolution. In fact, what would be ideal is a group of us sharing our on-board room correction graphs where available AND our REW or OmniMic graphs!
To idealistic?
