Could anyone tell me what's wrong in this acoustic graph?

Post by hugo_inside »

Hi guys,

As a nerd in acoustics graph interpretation, could anyone tell me if my control room acoustics are good. I'm thinking of improve my acoustics but I don't know if now are so bad to spend a lot of money in it.

Here you have a video of my measurements:

RED - MAIN ENGENEER PLACEMENT
GREEN - IN THE CENTER OF THE ROOM
BLUE - AT THE BACK OF THE ROOM

And here you have many kind of graphics I suposed it's important. RT30 in three different places.

Could you help me please?

to me the room seems very dry and at the mix position fairly even. how are your mixes translating?

Pics resize done.

I think my mixes sound good. Perhaps customers in studio tell me often, it sound a bit harsy, but quite good in a car or home equipment.

Here you have some examples:

Nu-metal

as a quick review - it seems OK from a room decay standpoint. if you're getting some harshness - consider checking the reflections off the console and equipment to see if you're getting some issues between 5K-7K where you're turning up the HF a bit to compensate. i've seen cases where some interference @ 5800-6200hz ends up causing a slight increase by the engineer and resulting in a slightly brittle high end on crash cymbals or piano.

I'm thinking of soffit my monitors, but I don't know if I need it bearing in mind the acoustics measurements results.

What do you think about?

it may be you just need some harder surfaces exposed to bring up the mid and HF decay times as maybe the < 200ms decay is causing you to adjust up on those frequencies. some widely spaced slats across cloth absorbers can help bring this up without interfering with the lower frequency absorption.

The whole front and rear wall of the control room are absorbent. What about mounting a pair of QRD diffuser?

you could try diffusers.
