The studio itself underwent a custom renovation. It was designed and completed by three professional studio builders: an architect, a contractor, and a sound designer.
The recording space was constructed around three walls that were built from 50 pound cinder blocks in the perimeter of a 1924 craftsman detached room. The cinder blocks are almost completely solid except for a small air gap in the middle, to block low frequencies from going in or out. This will dissipate sound waves and reduce reflections so the mics are only recording the original source.
The walls are floated and filled with multiple layers of sound deadening-defusing material. This further enhances sound absorption in the room and restricts sound waves from returning to the recording mic and introducing phasing problems.
Ceiling height is 11 feet. The space between the ceiling and roof also contains layers of sound deadening-defusing material. In addition, there are two strategically placed holes in the ceiling itself. Thus, the entire dampening area between the ceiling and roof serves as a "bass trap", which minimizes undesired low frequency reverberation.
The back wall and one of the corners have slight reflections. The room itself has less than a 1/4dB spike at 66hz. Both aspects are negligible so you are left with a sonically eloquent room, ready to record your music.
Originally, the design featured a large iso booth. But after tracking vocals and drums without a booth, it was determined to be unnecessary. The space has a much more relaxed, "living room" creative feel without it.
