Having an accurate representation of the sound being recorded is critical to so many stages of the process. For choosing the right mic. The right mic position. EQ’ing and compressing the signal correctly on it’s way into the computer. And of course for mixing and mastering.
The Light House control room is outfitted with high end MSR ZSound™ 3D diffusors and an MSR Dimension 4™ absorbers and Abfusors™. Mineral wood absorbers capture frequencies much lower in the spectrum than Auralex foam, which is fine for say a vocal booth but can mislead an engineer to believe a mix is muddy in the control room because Auralex absorbs lots of high frequencies but does little to absorb reflections of lower mids and bass frequencies.
