My studio in progress
I am currently finishing work on HUGE sound generation and capture facilities, a one-room compromise space for tracking, mixing, rehearsing that also serves as a deluxe spousal doghouse.

It is made of stucco'ed cinderblocks, whose voids were filled with sand. The exterior dimensions are 16' X 23'. The walls are 10' tall, with a cathedral ceiling peaking at 14' (although the roofing truss pushes that down to a flat surface at about 13'.
Because it is a detached building, with its own HVAC, on three acres of wilderness, with nearest neighbor a rocker with his own studio, I am not pursuing much in the way of sound abatement.
Since it is a compromise space by design, I am trying to perform some broadband absorption without killing the room altogether. I am using a mixture of:
1) Ethan Wiener low bass traps with deliberately reflective surfaces to keep high end from being totally dead
2) 4" of OC703 across the front corners of the room, floor to ceiling
3) a polydiffusor running across the roof-truss-induced flat space on the ceiling
4) panels of wrapped 2" OC703 mounted on walls and ceiling with a 2" offset
5) a course of built-in book cabinets along the bottom level of the room to act as diffusors.
6) Thick heavy curtains (with moving blankets at the core) for the two big picture windows.
Whaddya think?
