I have a garage that I want to use as a recording / mixing space. The dimensions are 6 X 3 with a 2.7meter ceiling. I already covered the whole ceiling with around 20 inches of light yellow fluffy insulation and want to do the same thickness for the entire back wall. This leaves the front wall and side walls. What can you folks suggest for this space? The walls are concrete and so is the floor. I should also just say that I will be recording acoustic guitar in this room.
thanks!

Make sure you get all the corners. Then do your RFZ. Then do a checkerboard pattern on the rest of the side walls. Then maybe do the entire front wall depending on your bass response.

Since my entire ceiling and entire back wall will be one giant absorber, that really leaves the two front corners. I will do those next so thanks for your input. For the side walls, do you mean alternate between wall and absorber on each side as per this diagram? I was thinking of making them floor to ceiling absorbers and having two for each wall.

That looks great. Yeah, do the front wall the same as the back if you can. For recording, it should be fine but depending on where you place stereo speakers (if you do) you may need to address the reflection zones.
Cheers,

No, they need to be symmetrical. What is meant is :- place one fully absorbing, then one reflecting, then one fully absorbing, then a reflecting etc etc down a wall - then exactly the same on the opposing wall - directly opposite each other. |

Ok this is my understanding:
Since your ceiling and rear wall will be 100% treated then yes, your front (and side) corners (remember, each room has 12 corners) will remain yet to be treated. How much depends on your measurements and desired results.
That is step 1.
Step 2 is RFZ. Use the classic mirror slide process to determine where those locations are then treat. Depending on speaker distance you'll need either one or two on your left and right. Your ceiling and rear wall are treated so you're good there.
Now step 3 is to improve modal response and/or treat ambience. This is where your graph above is correct. This alternating pattern will be done behind you (not RFZ). I realize this contradicts what steve says but, again this is MY understanding, you are looking to eliminate flutter echo by using alternating absorption. Thinking logically you will not want two sides treated, then untreated, then treated etc.. You will want an alternating pattern so a reflection can only go one direction and not return ad nauseum.
Be a light unto yourself. Think logically and you will arrive at a good solution.
-m
PS - Don't be afraid, and indeed expect, to make mistakes at first. In the beginning it's ridiculously complicated, then manageable and then fun. I don't know what your level of understanding is but remember you can always move stuff around after placing it if you don't like the result.

I don't know what your level of understanding is but remember you can always move stuff around after placing it if you don't like the result. Your logic makes sense to me but I think the poster above was talking about mixing position. So if you mix you would want treatment on both sides of you equally. I think the only way to achieve this is by having moveable absorbers so I can have symmetrical absorption for mixing and asymmetrical for tracking. How does that sound? |

I talked about that in my post. See where I said "...classic mirror slide process..." and then "..this alternating pattern will be behind you (not RFZ).."
