You'll need a soundcard. Then you'll need a stereo-1/8th mini to mini cable or mini to RCA depending on the card.
Look for a long cable at monoprice if you don't have a laptop to move the computer around. Shop around online for a good deal!

Then you use REW as per standard procedure, I'd start by reading its help file, it shows you step by step.

Make sure to set the meter to C-weighting and inside REW apply the correction file I have attached here:

If you need a soundcard and don't have one, I'd recommend this:
https://www.amazon.com/Behringer-UCA...ringer+usb+dac

Alternatively you could get a CSL UMIK-1 and not use the CM-130/UCA for REW. It would be more accurate and less fuss.
http://cross-spectrum.com/measuremen...ated_umik.html
You'd still want to keep the CM-130 just to ensure the sens factor/SPL calibration is set correctly for usage in REW. (You'd set REW to C-weighted SPL meter readings mode and the CM-130 to the same, play a 100hz sinewave (do not play lower than 100hz! 1khz is also acceptable to use.), and then note the difference in db's, and then adjust the sens factor in the UMIK cal file until you get the same SPL number with both meters. The sens factor isn't in the CSL cal file, you have to add it from the miniDSP cal file.) Once you do that you never have to do it again (unless you want to ). That will ensure that the SPL reading you get with REW is valid. Otherwise you are putting your faith in miniDSP's china factory of being correct.

If you don't get the same number, more or less, then you've done the SPL calibration wrong. Should be within +-1db if you can.
