Hello to everyone. I have been trying very hard to figure this REW thing out. I have read everything many times. (Don't understand most of it but I have come a long way!) I have been on and off it for about a month now. I am mainly interested in getting an analysis of my room acoustics to help make an informed decision on what acoustic treatments to add to the room, if any.
I am using a digital RS Meter, HP Laptop dv9410us(Vista 32 bit), with external USB Blaster X-FI Surround 5.1 soundcard, running to a Yamaha HTR5750 receiver(set to 2 speakers) with Klipsch Synergy Sub 10. I now believe that I have all connections, card settings(all "extras" turned off, etc), input levels, sound card cal and RS meter cal correct now, or at least as far as I can tell. I do the SPL calibrate routine and it seems to work correctly. (I am doing the steps in order).
However, when I go into check levels before measuring, I can only get "level OK" by lowering the RS meter's range down to 60db. Of course, at this level the RS meter doesn't even regisiter the 75 db and just tops out at a blinking 70 db.(It appears that the REW SPL reading comes out close to what the RS meter would be had the range not been so low). When I do run at this level I get a measurement that I think looks OK, but it just doesn't seem like it can be since the RS meter didn't even get up to the 75 db.
I guess my only question for now is am I fighting a losing battle with this setup? If I am then I have until Saturday to return the soundcard to Staples. I really don't need it except to run REW!
