I've spent my entire Saturday trying to get Room EQ Wizard to work for me...
1. No matter what I do, it always measures my response at around 140db: making it impossible for me to set a target level or use filters.
I tried two different input devices: a Behringer microphone and a radioshack sound meter. I have tried two different sound cards: the internal sound card for my computer (realtek?) and my USB Creative Extigy device (which I used for all output regardless)
I dutifully used the sound meter to make sure I am calibrated at 75 db. And I used the calibration file for my sound meter. I even calibrated my soundcard which didn't show much deviation from a perfect response.
Also the curve as it gets out past
What could I be doing wrong?
2. Am I right in believing I must go through all of this filter configuration after the measurement is made if I'm going to just use convolver on the pc to handle the .wav data? i.e can't I just output the unfiltered response in Wav from the file menu?
3. Am I right in understanding that none of these tools will help for freqencies over 500hz? Isn't there a way to use the computer (like the high end audiophile device Tact for instance) that can equalize the entire spectrum?
4. Enclosed is a graph of one measurement. Notice the wild swings of response of my speakers. Is this normal? These speakers are expensive (to me...) Martin Logan Electrostatics which radiate the same amount of energy behind and in front of the speaker. I got this pattern even when I used one soundcard for the input and one soundcard for the output: so I don't THINK it is feedback.
Thanks in advance for help. I'm pulling my hair out (and I'd like to keep as much of my hair as possible if you know what I mean)
