I've been mulling this over now for too long, time to fish or cut bait!
The only place I have to record in is the one I've got! So I have to make the best of it, and I need sound advice. Pun intended.
It could be a worse space, but not by much I think.
It is a wooden structure on a concrete pad, 6.0m x 4.60m x 2.32m. It has 90mm stud walls, shiplap outside, 9mm hardwood ply inside, with glassfibre thermal insulation.
The intended primary use is for the recording of acoustic music. If I can get that part of the acoustic treatment as good as I can, I'll be happy. Any considerations for mixing are secondary at this point, although not completely out of mind.
My research so far suggests that I need broadband absorbers on the walls, bass traps in the corners, and a broadband cloud above the performer.
But, how much?
Which brings me to my second question; can somebody please guide me through the process of making an acoustical analysis of the space
before I undertake any changes?
I would like to understand that process and measure the effects of any treatment as I go along. Suggestions for Mac software would be appreciated. I'm just looking at FuzzMeasure, don't know how it measures up though!
Corning 703 is hard to find and expensive in the UK, so I propose to use Rockwool for the absorbers and traps.
I realise that this room isn't ever going to sound wonderful, but I believe I can go some way to mitigating the sonic damage it wreaks on a good acoustic guitar, and that really is the focus of my efforts.
I just discovered SketchUp, so I've made a jpg which shows the layout, and I've added absorbers and traps according to what little knowledge I have.
The blue panels are 1200x600x50mm and hung away from the walls.
The red panels are 1200x300x100mm, except for the cloud which is1200x1800x100 and suspended below the ceiling.
I've omitted the doors, windows, and ceiling for clarity, but they're there!
I hope I'm on the right track. Any help whatsoever would be greatly appreciated.
Dave.
