Isolated electrical circuits for each individual room are a must in a recording studio. The proper amount of amperage is also a must. Not enough amperage will surely cause your breakers to blow. Consult with an Electrician who is familiar with studio setups to insure that wiring and voltage is regulated and conforming with local codes.
Unregulated Power Supplies (UPS) should also be in place just in case there is a power failure. This will insure that valuable equipment will not blow up or cause a fire. If there is a case of a power outage the UPS will provide enough time to backup important computer files and safely turn off your equipment. Some studios will have complete generator systems in place to keep the studio running for the remainder of the session.
Improper lighting can also cause buzzing ground issues, especially fluorescent bulbs. Avoid using these in any studio. Dimmers can also cause many problems. The average household dimmers will surely put a damper into a clean sound. Make sure that professional grade dimmers are installed to avoid ground noise. Always listen carefully to signals being recorded before committing to a final take. There are a countless number of accounts that the engineer discovers electrical noise on takes during the mix process.
If you are serious about your studio, may I suggest balance power or a separated panel with neutral power conditioning. The evil problems of ground issues are a direct reflection of sources returning or looking for a different ground. Voltage potential between neutral and ground will certainly change your way of looking at things… for example, .5 volts between neutral and ground is the maximum allowance by UL code that electronics will operate optimally without potential induction issues. I would suggest having a meter installed to rate this. Logging this information and having a good rapport with the local electric company would not hurt at all.
This is another very important area that is often not considered. Studio gear gets very hot. The lack of adequate cooling could result in equipment failure or damage. Blowing up equipment is no fun and it gets very expensive. Some recording studios have a separate Machine Room for computers, tape machines and power amps that is highly air-conditioned to keep everything cool. This also cuts down on the noise from the fans on such units, which can distract concentration from listening in detail in the control room. Having too much air conditioning could also result in moisture or condensation build-up that may also damage the gear. Water in general is bad for electronic gear.
The return air system is used to pull heat out of needed areas and also provides an air intake for the AC units. These are placed in key areas where there is a build-up of heat from the gear, for example near the console or in the machine room.
Separate Rooms: Control Room
Most studios have several isolated areas for recording, mixing, and production. Soundproofing is the main agenda when creating multiple rooms in a studio. To achieve this, the main objective is to make the rooms airtight. If air cannot leak in or out of a room, there will be less chance of sound leaking in or out as well.
Most pro studios have double doors that create a sound lock to help prevent noise leakage. They also have very thick double walls with interior air gaps to also help trap unwanted sound. The floors in the studio should also be floated which means they are lifted from the ground to help further prevent extra vibrations and leakage.
The first focus would be the Control Room where the mixing console and outboard gear are contained. This is where all of the recording and mixing is controlled, hence control room. The acoustics in this room should be designed for hearing the exact sound that is being recorded or mixed. The sound of the room should be as natural as possible for accurate representation of the original sound translated to the speakers in the room.
The first rule for an appropriate acoustically treated room is that there should be no parallel walls .If you were to clap your hands in a room with hard parallel walls you would here the sound bouncing back and forth, this is known as a flutter echo. This is neither good for recording or mixing. The trapping of unwanted bass is important for a room to sound great as well. Twenty five percent of the room should be assigned for bass traps for an adequate mixing room. Acoustics will be discussed appropriately in more detail later.
Separate Rooms: Live Room
The next focus of equal importance would be the Live Room where the music is recorded. This is where the musicians and vocalists perform on the microphones. Live rooms should have more versatility to be able to adapt to different recording situations. Wood floors for example are great for reflection of sound, which creates a brighter tone. If a warmer tone is wanted, one could simply place a rug on the floor. Many live rooms also have a great deal of glass to see between rooms for communication. This is also very reflective. Many studios use curtains to control the amount of reflections coming off glass or hard walls. Non-parallel walls are again needed to eliminate any flutter echoes.
Some studios also contain a vocal booth within the live room. This would be a smaller room designed for vocals. They may also be used for guitar amps and other instruments. There are no rules for what this can be used for; its main purpose is for additional isolation during the recording process. Glass doors or windows are used for visibility of the artists and those working in the control room.
Many elaborate studios may have multiple control rooms and production suites. Lounges and proper bathroom facilities are important in keeping the creativity flowing. A dining area and kitchen are also a consideration if budgets permit. Many hours are spent in the studio when working on projects. It is important to have all the comforts of home to keep everyone happy.
A few proper offices are necessary for the client to be able to have private internet access and to handle business without any distractions.
All studios are designed differently. Whatever can be imagined can be created. There are no rules, only guidelines.
Booking the proper studio
Where one decides to record is as important as what they are recording. If a band is located in Los Angeles why not just find a studio in L.A.? There are plenty of studios in L.A. with amazing gear and fabulous rooms yet the distractions of being in their hometown could take away from the focus of concentrating on the recording process. Many artists will book studios in remote locations to avoid outside interference and distractions. Privacy is very important in the entire process. Friends coming over to drink beer during the sessions could definitely hinder the process.
When budgets do not permit then finding a studio in a location that is suitable for the logistics of all who are involved in the project must come into play. The most important thing is that everyone feels comfortable in the location. If you have to pack your 9mm to get from the car to the studio then you may want to reconsider. When booking the studio look for a good location, a good price and make sure the gear and the room is adequate.
Deciding where to build a studio
In business, location is everything. Asking yourself if you have enough clients in that area to sustain all of the bills that incur for your studio, must be the key to your decision. Only a few very talented industry pros have the luxury of clients going out of their way to work in a remote location.
Purchasing a building for a studio is a great option for many reasons. By owning the property you become the landlord. Therefore you can do a build out as you please. This is a great investment as an alternative to a lease. Many Artists these days are buying houses and renovating them as Recording Studios. Many mansions have been converted into studios. This option for obvious reasons definitely brings the comforts of home right to the recording process.
Whether building a private studio, a home studio or a commercial facility, they all take a bit of investigation before committing to the expense. Parking should be considered as well as local conveniences such as anything that your focus client base may desire. If your clients are country artists I don’t think they would like recording on South Beach and if your clients are looking to be around where the action is the mountainside resort studio is probably not ideal.
