First things, first. I really appreciate each of you taking the time to comment in my thread! It does help keep the motivation up knowing I'm not the only one looking at the pictures I post. The feedback is also a huge help because it's easy for my OCD to make some of the design decisions impossible for me. So, each of you give yourselves a hand
Now, I got a little delivery today.
That's a calibrated USB mic. Here's where I got it from
. Each mic is individually calibrated. That little silver USB drive is the cal file for my mic. Not the same cal file for all bajillion of these mics. I believe I read somewhere that these things are pretty close anyway, but it's only a few extra dollars compared to PE
to have one individually calibrated. So, why not?
The beauty of the USB mic is it simplifies the process a bit. No more external power supply needed. My Mac picked it up with no issues. The current beta of REW supports USB mics as well as HDMI output for 8 channel calibration. This should greatly simplify the setup process.
I'll try to work through REW in the next few nights to get everything calibrated and see if I can take a measurement or two of my fan using the RTA function. Hopefully it will help narrow down the issue. I tried it with the built in mic on my laptop, but the fan noise is not much above the noise floor in the room/computer, so I'm not too optimistic. But I was planning to get one of these anyway if for no other reason than to keep my calibrator honest when I get around to a pro calibration.
