Pink noise or sweep?

Can room measurements be done with pink noise from an external source? My computer is at the opposite end of the house from the HT room. I tried to run an interconnect cable from the sound card to receiver in the HT room and had loud buzz (ground loop?). I'm using the emc8000 and the ub802 and I have enough mic cable to run the length. Tom

No, you really need to have the computer fairly close and use the internal sweep. I know it's a bit of a pain, but long cables just introduce noise as you've already seen.

Often people use laptops (with an external soundcard) for REW, as it's nicely portable....

Myself, I got an old K6-350MHz PC computer for REW duties. It's a bit painful, so I would recommend something a bit faster, but my point is that for almost zero dollars (and sometimes free), you can use any vintage computer to run REW.

Ok, thanks for the info. Tom

I'm posting a specific problem in my own thread, but your comment is interesting. I have a better computer, but can't get things working.

Maybe you could do a sticky on how to put together something like you have.

I'm having trouble with w98 millenium and a soundblaster card. ( You've posted in my thread about it.) I tried a different card and had the same problem, so I figured maybe it's the OS. Maybe w98 would work better than Millenium.

I tried with XP on a 2.4 GHz machine, but can't get Java on the thing. If w98 on a 400 MHz machine will work, then I would love a few specifics so I can use one I already have.

I use XP with SP2 for REW. I believe Java requires that.... I always leave the Windows auto update on, so it's always the latest version.
