In Reply to: I never got satisfactory results using a spectrum analyzer and calibrated mike with white noise posted by Soundmind on July 4, 2006 at 05:20:56:
I'm not unfamiliar with the process. I worked for a number of years as a soundman for a lot of bands (I was rented out with the equipment by the music store I worked for) so feel I have a good grasp on setting up frequency equaliziers in a wide variety of situations. I have certainly seen many situations where an EQ turned a sonic mess into a pretty dang good sounding system.As for the white noise, it was only one of several methods I was using to configure things. The final settings and decision were always based on listening to music.
Keep in mind that I was not getting "bad" results. There was improvement in the room frequency response, but it wasn't worth the ever so slight degredation in other sonic characteristics. It is no surprise that messing with frequency response will change imaging, depth and other spatial sonics. That's a Pandora's Box of intertwined issues.
It is easy to forget that working to stengthen something in one area always has drawbacks in another. As an analogy, the Japanese Mitsubishi Zero fighter in World War II was famed for its incredible manuverability. They achieved that by leaving off most of the armor plating that protected the pilot in American aircraft. The reduced weight helped manuverability. There are endless examples where fixing one problem creates another elsewhere.
Audio is much the same. I did get an improvement in frequency response, but it was not worth (to me) the other compromises involved.
