No, the RS meter is quite poor above 5K. It works well for low frequency duties when used with a calibration file ( found here), but you may want to purchase a better mic for full range. |
Okay, I'll look into that. I'm sure there are plenty of threads here about what mics are good.

Yeah, that seems like a showstopper. You can use REW as the measurement and graphing tool (as you've suggested), but I don't know of any plug-ins that will allow the equalized modification of the REW's output during sweeps etc. |
I did some more googling, and I may have found a way to do it. Maybe. I found a "standalone" version of that nice looking
EQ I had found. Unfortunately, it seems to be hardcoded to only take its input from the inputs of a soundcard. (I guess it's designed for use during recording.) Also, it appears to only be looking for installed soundcards that are running an
ASIO driver. The nForce chipset on my home computer has such a driver, but God knows whether the USB doohicky on the car computer will. So, that's two strikes against this particular EQ, but there's still a faint hope I can make it work. How?
For the input issue, there's a product called "
Virtual Audio Cable". In theory, one can use this utility to create "fake" inputs and outputs and "wire" them all together. So, I could create a fake output and tell REW to use that, and have that virtually connected to a fake input which I would then tell the EQ to use. There's a
universal ASIO driver out there, and the Virtual Audio Cable guy claims it will work with his program.
Even if this scheme can be made to work, it seems like it will confuse the out of REW, since REW is going to be try to control the volume, etc., of an imaginary soundcard output. Hopefully, that functionality can be disabled if necessary.

On a less sophisticated scale you could use REW to create an accurate frequency response of your car without equalization and then use this information to pinpoint the areas you want to tame with your equalizer. There would be no feedback to how well your settings worked though. |
Yes, I was thinking that might be a good fallback plan. I could certainly use REW in the usual fashion to tweak the level and cutoff frequency of my "subs". (They're really just 6x9s, but they do have their own amp.) Then for the full range tweaks I could use REW's filter simulator thingy to "design" a correction curve. Then I could transfer those filter settings to the parametric plugin in Winamp. As you say, there'd be no way to test the resulting output, but if everyone has done their math correctly, it might be pretty close.
