Building a studio in Norway

Great! OK, now I downloaded it fine.ill try again..
Actually, the first posts just say: "The control room is about 24sq meters". And now you say it is only 20 m2. None of those are any use: we need exact dimensions, not approximations. Modes occur at very specific frequencies that are directly related to the dimensions of the room. The modes are very narrow-band resonance, so precise dimensions are necessary for predicting the modal response of the room. The REW data is showing lots of things that could be modal, but I need the dimensions of the room to be able to determine for certain. The other thing I noticed is that there is a very, very large difference between the overall response of your left speaker and your right speaker, implying that the room is not symmetrical. You did mention that "the roof is rising left to right from about 2.20m until 2.70m", and that is probably part of the problem, but there seems to be more to it than just the difference in ceiling height. However, I would suggest that you start by fixing the ceiling problem, then look for what else might be causing the asymmetrical problem. It is absolutely essential that the room must be perfectly symmetrical, at least for the front half. The left side must be the mirror image of the right side, in all senses. Right now, there seems to be something very large and reflective close to the left speaker, which is not the case with the right speaker. That needs to be fixed. Apart from that, the response is fairly typical of an untreated home studio, so that can be improved a lot with proper treatment. But first solve the problem with symmetry, then do another REW test to see what treatment is needed where. And also please provide the exact dimensions of the room. - Stuart -Think i mentioned the room in my first posts, its about 5 meters long, and 4 meters wide.
Hi, yes the roof is rising. I put one cloud above the mixing position and was thinking putting up a couple more further back in the room.
I tried to make a drawing of the room, marked with inches. Is this room a problem?
Here is my latest picture from the control room.
Thanks! joakim
Unfortunately, clouds will not fix the problem with symmetry of your ceiling: you need to physically make it symmetrical, by taking off the drywall, adding new framing, then putting new drywall on. - Stuart -Hi, yes the roof is rising.
