Help with acoustic treatments in home control room?

[Allbaldo]

Hello!

I mix and master records out of a spare bedroom in my house. It's about as not-ideal a space as you could hope to end up with, but it's what I have, so I have to make do. I'd love some help with treating the room to make it as good as I can. I'm including a Sketch-up picture for reference…

The ceilings are 8' high.
The room is 10' 1" wide
Most of the room is 10' 5" deep, except for the space near the entrance, which is 12' 11" deep.

Yeah. Nice, huh? Almost a cube. The price is right though.

There are 4" thick rock wool panels straddling the corners floor to ceiling on either side of the desk, which I was unable to add into the Sketch-up I did. I'm in a position to buy the materials to do more diy treatments for the room. Obviously, there are challenges as there are doors, and an uneven back wall. Any suggestions would be a huge help. Thanks for your time and consideration!

Sorry, I forgot to mention that I'll be doing hardwood floors in the room. Currently there are DuPont laminate floors. Also, sorry for Doune posting the picture!

Hi Stephen and Welcome!

Ouch! Obviously, you have to do something about that! It won't be much use for mastering as it is.

Obviously, there are challenges as there are doors, and an uneven back wall. Any suggestions would be a huge help. Thanks for your time and consideration!

I would get rid of that closet at the back to start with, then put up thick absorption on the rear wall (6" of 703, for example, and tilted forwards), then put the usual treatment for a CR: first reflection points, ceiling cloud, checkerboarded absorption on the side walls, then the rest on the ceiling, until you hit your 265 sabins that you need.

I forgot to mention that I'll be doing hardwood floors in the room. Currently there are DuPont laminate floors.

I would stay with the laminate flooring. Hardwood floors sometimes need to be raised off the subfloor, leaving an air gap: that's not good. Hardwood flooring is also thicker than laminate, thus reducing your ceiling height...

Don't forget your room as more than just 4 wall to wall corners. You can also treat ceiling to wall and floor to wall corners around the room. That room is going to be hard to get right but with enough treatment it can be usable. See the following for some ideas on areas to great and set up.
