I think it will all depend on the quality of your sound card, but most of the laptops I have looked at recently seem to have pretty good sound cards... and HDMI out as well. So either a 3.5mm to stereo RCA from the headphone output or an HDMI cable should work.
EDIT: The headphone out did NOT work for me. I never could get a clean output. The HDMI output worked beautifully... including the ability to see REW on my 10' screen.
I just picked mine up from the post office. It is in fine shape with all the parts there and the box in good shape. I can't work with it until tomorrow night. I am looking forward to messing with it. I am not looking forward to learning REW. I am use to the OmniMic and know it well, but I have never used REW. As a matter of fact, I've not even downloaded it yet. I'll do that tonight and start getting familiar with the program.
I got around to trying mine out tonight. This is my first exposure to REW so I don't have anything to compare it to. Even so, setup was super easy and I haven't found anything to complain about so far (other than my general lack of REW knowledge). The included clamp and tripod are pretty handy too. This was just what I needed to get this PB13-Ultra under control in my living room.
Got mine last week and have been learning REW with it since then. Super nifty and lets me geek out on measurements, but one thing I've noticed is the "dB FS In" is really low, ~ -36. I haven't figured out a way to get it up to the recommended -18. Mic mixer volume in Win 7 maxed out at 100 and input volume maxed out at 1.00. Does dB FS In need to be -18 or is -36 ok?

I have been getting a similar message, stating that REW expects levels at -10dB or higher, but it will still plot the curves for me. I still have lots room to increase volume, just getting used to the way it works before doing so.
That difference of @ 7.5db at 10K is quite significant ( & very much in keeping with what Herb recently discovered when comparing his calibration vs P.E.s, for the same UMM-6 microphone ).

It could be differences in calibration methods and mic orientation. To be more precise I should use the orientation for which the mic is calibrated... and I did not give that much thought at the time... all were at 90°. I think I have two files from Herb on my ECM8000... one for 0° and one for 90°, if I am remembering correctly. Of course I can't hear 10kHz very well anyway, so for me it would not be significant.
Not sure if one of these exists, and after all the issues I've had, figured I'd start one here and hopefully save anyone else from buying a new MobilePre thinking their's was shot! :rolleyes:
Equipment and Software
This is the MobilePre I'm using...
Okay, so first things first, go download...
It's been discussed that maintaining a list of sound card/mic pre/mixer/mic options might be valuable, including any pros and cons or notes on use. To kick it off, please post your REW signal chain components (not including cables) and what operating system you are using.
Here's my current...
Need to check a measurement mic frequency response and of course a speaker will color the graph.
I have heard an Air Compressor can be used to generate full audio spectrum Pink Noise. True? Other sources of Pink Noise?
Or.. I there a good DIY way of getting an accurate frequency response graph...
Hi,
The only sound level meter that I see on the Radio Shack site is #33-099. Will this work with REW or would I be better off finding one of the meters shown in the help file (33-2050, 33-4050, 33-2055)?
Thanks,
Steve
