You record it in layers with close microphones and build the room afterwards, because a Studio City living room has neither the height nor the noise floor for a section sound. The ceiling is the binding constraint, not the microphone list. A Decca tree wants its centre capsule three metres or more above the leader's head, and a 2.4 m ceiling does not contain that at any angle. Layering four players three times does not produce twelve players either, and the correction is physical: the chairs have to move.
Why does the ceiling decide this and not the microphones?
Two numbers fall out of the room dimensions before anybody opens a microphone cupboard.
The first is the floor-to-ceiling axial mode. Divide the speed of sound by twice the height and a 2.44 m ceiling gives a mode at 70 Hz, inside the cello's lowest octave. Below the Schroeder frequency, which in a room that size lands around 200 to 300 Hz, the room behaves as discrete resonances rather than a diffuse field (room modes). In that range moving a microphone 30 cm changes the recording more than changing the microphone does.
The second is the ceiling reflection. A microphone at 1.4 m in a 2.44 m room has the ceiling 1.04 m above it, so the reflected path runs 2.08 m longer than the direct one. That is a 6.1 ms delay, putting the first cancellation at 82 Hz and another every 165 Hz, straight through the register where violas and cellos carry the chord.
What does a Decca tree need, and why will it not fit?
Roy Wallace built the first version at Decca in 1954: a T-shaped frame carrying three microphones, left and right about 2 m apart, the centre roughly 1.5 m forward of them, the whole array flown eight to ten feet above the conductor (Decca tree, Mix). The omnidirectional Neumann M 50 became the standard capsule for it from 1955.
The array works for two reasons, and a low room removes both. Height buys time, so the direct sound arrives well ahead of the first reflection and the ear separates the players from the hall. Omnidirectional capsules up there are hearing the room deliberately, because the room is worth hearing. Drop the frame to 1.8 m under a 2.4 m ceiling and the microphones sit inside a reflection, with no time gap and a room nobody wants.
So what do you actually put up?
Spot microphones first, because they are the part that survives the mix. One per desk at 60 to 80 cm, aimed between bridge and fingerboard, rotated 20 to 30 degrees off the f-holes. Small diaphragm cardioids, matched across the section so the stack does not change colour pass to pass.
A boundary microphone flat on the floor, two metres in front of the players, is the one array trick that gains from a small room instead of losing to it. With the capsule on the surface the direct and reflected paths converge, so the floor bounce has nothing to comb against, and the result is a centre image with low-frequency support no stand-mounted microphone in that room gives you. Then treat the ceiling above the section: 10 cm of mineral wool with a 5 cm air gap behind it buys more at these distances than anything on the walls.
How many players, and how many passes?
Three passes of four players correlate with themselves. Same bow noise, same intonation habits, same seat, same distance to the same capsule, so the stack reads as four loud players rather than twelve quiet ones. Detuning the passes or nudging them in time does not fix it, because the ear has heard that trick from chorus plugins since the 1980s.
What works is moving the physical arrangement. Shift every chair 60 to 90 cm, rotate who plays which line, change the spot distance by 15 cm, and ask for a different bow distribution on the second pass so the attacks do not land on the same frame. Four passes handled that way reach a 16 player texture that holds under a vocal; the same four from fixed chairs will not.
What is the noise floor going to do to you?
A string pianissimo puts very little pressure on a capsule, so the limiting number in a Studio City house is the ambient level rather than the preamp. Ventura Boulevard and the Ventura Freeway feed broadband traffic noise into the flats from early morning onwards. A room measuring NC-35 is fine for drums and unusable for a quiet string passage, which wants something nearer NC-25.
That turns into a scheduling decision. The quiet window in the flats is roughly 05:00 to 07:30, and the afternoon is the worst of it. Air conditioning goes off for takes, which gives about twenty minutes before the room temperature pulls the tuning, so the session runs in short blocks with a tuning check at the top of each (choir in Glendale).
What is on the lot, and when should you book it instead?
Mack Sennett opened a studio at Ventura Boulevard and Radford Avenue in 1928 on what had been a lettuce ranch, and the district that grew around it took its name from the studio (Radford Studio Center). The lot still works, carrying 18 sound stages from 7,000 to 25,000 square feet (Radford Studio Center), with a roughly billion-dollar expansion and room for 20 to 25 more stages in motion since 2023 (Deadline).
A sound stage is not a scoring stage, and booking one for strings is an expensive way to learn that. A shooting stage is built dead so dialogue comes back clean, so a section recorded there has no tail and the space gets added in the mix anyway, which a treated room does at a fraction of the rate.
The purpose-built rooms sit on other lots. The Eastwood Scoring Stage is on the Warner Bros. lot in Burbank, a separate incorporated city ten minutes east along the boulevard. The Barbra Streisand Scoring Stage is on the Sony lot in Culver City, a 6,100 square foot room with a short reverberation time that has carried film scores since 1939, 30 to 40 minutes over the hill depending on the 405. Book a stage when the brief needs a real tail, a conductor working to picture, or more than sixteen players at once.
Jurisdiction changes the paperwork. Studio City is a district of the City of Los Angeles, as are North Hollywood, Sherman Oaks and Van Nuys around it, while Burbank and Glendale east of it are separate cities with their own permit offices and noise rules.
Where does the cello get in?
Ventura Boulevard is metered, the residential streets north of it sit inside permit districts, and the hillside streets south of it have no loading space for a double bass or a harp. Book in the flats, ask for an address with a driveway, and budget fifteen minutes per large instrument.
I have mixed and mastered records built on traditional instrumentation recorded in rooms never designed for it, including Eurovision entries for Ukraine (mixing bandura against an orchestra). Those credits with their sources are at /credits.
Frequently asked
Can I get a convincing string section in a room with an eight-foot ceiling? Layered, close-miked and placed in a convolution reverb of a real hall, yes. As a single-array recording where the room you are in is the room you hear, no. No microphone substitutes for the missing height.
How many passes of a quartet add up to a section? Three to four, but only if the chairs move between passes. Stacking identical takes from identical positions makes the same four players louder, not more numerous.
Is a film sound stage a good place to record strings? For isolation, yes. For tone, no. A shooting stage is built acoustically dead so dialogue is clean, which means paying for 20,000 square feet of floor and still adding the whole space in the mix.
