i have a small room of about 8.5w x 12.5l and 9 fts high.... i just want to make it dead as i only want to use it to record strings, winds and other instruments except drums and all.... the walls are angled ... ceiling is sheetrock and floor is concerate one a very reflective...... i have two vertical corners giving me depth of aroung 16" .. i can make the wide band absorber also in the angled wall if it is necessary .... i initially thought to make it dead by absorbation material like rockwool or something....... what i have interesting in my room is that one of my wall is framed like a pyramid diffuser in which i am getting air space veriy from one point to another... i think its' good to be make highs live and must be that shape helps me out....... ny suggetions?

To record strings in a room that tiny my advice is to keep the cement floor, but make every other surface as dead as possible, including the ceiling.

kewl

i have cement floor... should i put carpet on it? i am planning to make it full with mineral wool and covered with sheetrock... the ceiling is already sheetrock and insulation inside.... wht abt if i have remain some walls without sheetrock and only cloth covering?
 
No Carpet!

The carpet will only absorb high frequencies, also a highly reflective floor will give some life to the sound. You could use vinyl flooring.

ok.

So r u agreed on the way of construction i am going for..... i am using 3" insulation rockwool.....

Didn't you read what I wrote? Keep the cement, or cover it with vinyl or something else that is reflective. A hard floor and all else dead at all frequencies is a good way to treat a small room for recording acoustic instruments.

Is it OK to do the opposite, deaden the floor and make the ceiling live? I have a very similar room, but for many reasons I'd like a carpeted floor. Thoughts?
 
By putting carpeting on the floor you will only deaden the high frequencies, your recordings will come out dull and boomy, you need to have balanced absorption all across the entire spectrum. There is nothing you can put on a floor to evenly absorb, so you must put it on the ceiling and walls.
 
diffusion

i think by framing shapes like diffusers can be helpful to make highs alive .... any suggetions?
 
M,

That's not so good if you plan to mike things from overhead, where the mikes are close to the ceiling. You'll may get severe comb filtering (sounds like a flanger effect) from reflections off the ceiling into the rear of the mike.

dead room, no problem

Careful not to make your room too dead! If you use an acoustic treatment, use one that you can easily adjust.
