THE MASTERING Room

COAST MASTERING was relocated and rebuilt in 2020 from the ground up, focusing on a variety of immersive and stereo formats, including DOLBY ATMOS, SONY 360 RA and AURO-3D. We did not just add speakers to an existing room, we started from scratch, digging down far enough to stabilize the room which now sits on an underground 30” slab of rebar and concrete.

Working with renowned acoustic expert Bob Hodas and project manager Bob Levy, we designed a 9.1.6 mastering environment before the first shovel went in the ground.

Multiple layers of sheet rock, quiet rock and hat channel were used to isolate and give consistency to density and reflections.

With nearly three feet of bass trapping custom-situated above the mastering room, we used Apertures from Stillpoints to both absorb and diffuse energy in the room as needed. This allows a very direct presentation from the speakers. Imaging and localization are incredible.

All our external gear is located to the right and left of the engineer position to prevent the console from obstructing the direct path of the speakers.
