advice on making my living room a mastering suite?
« on: December 05, 2007, 04:52:18 am »

here is a sketup of my living room. I have some ideas on how to balance things out in here, but was wondering if this odly shaped room could be treated to a level which it would be balanced enough for mastering. Given the placement of the doors windows, fireplace and kitchen, there is no rectangular symetrical geometry to use as a listening position.  index.php/fa/6889/0/

my inclination would be to add a "soffit" that matches the other angled wall and even put in a door to the kitchen to let you get symmetry and sit lengthwise in the room.

the other concern is the near squareness of the room...

there is a air-conditioner on the wall between the windows but it can probably be duct, and there is a fire place on the other angled wall. I would have to put the speaker in front of the fireplace and not use it. But it would make the most symetrical sense. I see your point with the squareness/ cubeness. But I don't understand your chart and what is the goal and what are the not so good results? Could you explain the measurments please?

the calcs just give a rough estimate on the rooms mode characteristics and the number of modes and the close spacing means that you'll likely need some more acoustical treatment than you might if the room had better ratios (which for the tall ceiling are around 19'x26' - 21'x30'). then again, how does the room sound?

since the ceiling is nice and tall, maybe you can use some of that space to add trapping there rather than just on the walls.  

in the "soffit" blocking the windows, you could duct the AC unit top and bottom on the wall and perhaps get it quieter in the same effort. you could also build part of the dividing wall behind the "soffit" with glass block to let the light from the windows into the kitchen.

Those are good ideas. The room sounds bright. It has a lot of reverb in the upper mids and highs. The floors are wood and that adds to that issue. The bass response is not the best either. Probably because where I site now is in the middle of the room. I will have to run some tests and take some measurements. I don't have an omni mic suited for measurment but I can borrow one from my freind next week. Thanks for the help!
