The physical construction of a studio can be as or more important than the equipment used in order to obtain professional results. The construction centers on several goals which are often not necessary in conventional construction. In the studio, one wants to eliminate external noise and prevent sound from leaking out of the studio as much as possible.
In addition, we want a mixing environment that is neutral, so acoustic anomalies of the room do not affect mixing decisions, making a recording that can sound odd when played in other environments. We also want recording spaces that either impart a very nice acoustic signature, or no acoustic signature so as to not to become distracting when listening to the music.
To this end, Candlewood Studios was constructed with details including outside walls that are solid concrete basement walls to prevent outside noises from entering, and constructed with insulated staggered (double) stud interior walls. The room dimensions were chosen to minimize acoustic anomalies. Gaps are acoustically sealed, electrical power is from a dedicated circuit, and the acoustic ceiling is further treated with sound absorbtive material above the ceiling. Acoustic treatments and bass traps are precisely placed, and the room has been professionally analyzed.
The live area is open and large enough to prevent unwanted coloration, and the control room is large enough to fuction as a secondary recording room.
