She's a good one for sure! :) I agree, I think the external sound card has issues. That doesn't explain, though, why I get similar whack-o results from the internal card on the laptop, and the Audigy 5/RX card in my desktop machine.

Thanks John, I appreciate all the info. That would have been super useful a week ago when I started this twisted journey. :) My wife finally saw my frustration last night and pulled the plug, by which I mean she bought me the Dayton DATS box. I think there's something wrong in the sound card(s)...

Hence my frustration. I've found really very little actual explanation of how to do some of these steps. For example, when connecting output to input, as you say, what cable should be used? Is this with the regular measurement cable or a special 'calibration' cable that's wired differently? If...

I thought I had done that multiple times, but perhaps not correctly. Is there a guide or video for that process somewhere?

I agree. It's just one of the things that don't make sense to me. It seems that every time I hook it up, I get slightly different results, but never anything usable. Are there any known bugs in Beta 60 that could cause this type of erratic behavior?

I absolutely give up. I went back and built a brand new cable, being extra careful of all my connections. I was able to get the calibration to (maybe) work on my laptop, but that's it. Everything else has given all sorts of crazy output, and errors that I can't make sense of. I've searched the...

So I checked on my laptop, with a totally different sound card, and got similar crazy results. One thing occurs to me... Do the cables going between the sound card itself and the measure box need to be anything other than typical "aux cables"? I feel like something must be wired wrong...

I checked, and there's no "listen" box checked for the line in or mic input on this unit. I did notice that the level set in one place doesn't seem to mach that in another, which leads me to believe that it's not giving me the full into about the inputs and outputs, but I have no idea if that's...

I'm sorry, I misspoke. There is no headphone jack on this setup. I'm using a USB external sound card, as shown in the 2nd photo attached to Post #13. If I switch to using LINE in, and run the soundcard calibration, I can only get reasonable results if I plug one side of the loopback in only...

Good catch on that mis-soldered pin! I had found and fixed that after taking the photos, and forgot to mention it, sorry about that! I've tried using the LINE-IN jack, but the input levels are too low to use. REW tells me that I need to do something to increase the level. Using the headphone...

You know, I thought that also, since you mentioned it before. However, I've tried it both ways and get pretty much the same results. Does the circuit itself look correct, as best as you can tell from the images?

Ok folks, I'm completely baffled here. Someone PLEASE tell me what I'm doing wrong. I've started over and built a new circuit from the images posted above. You can see what it looks like in the images below. I've read through the help guide for REW, and I think I'm doing the calibration steps...

Cool. Thanks so much for your help John. I haven't dug in enough to know much yet, but your software looks amazing!

Gotcha, thanks. Is it necessary to have a resistor capable of higher power handling, or is a typical 1/4 or 1/2-watt resistor fine?

Ah! Grounding, thanks. I appreciate the feedback John. I have a 5-ohm, 5W resistor on hand. Will that work, or do I need to buy something else? I've seen somewhat conflicting info on whether that resister needs to be higher wattage-capable, and if the specific rating is super important or not...
