One thing to keep in mind is that some that use laptops for graphing their room, use an external USB sound card, versus the built in sound card. One of the steps using rew and other programs requires you to calibrate you sound card by running a cable from the "out" jack to the "in" jack. I could never get my laptop to run this step.. I use my desktop computer, HT computer. It has jacks on the back of the pc, and I've had better luck than using a laptop. then you have to use a long cable to reach your seats. \:\)
