I have the opportunity to record in a church that is of modest size
with high ceilings and a lively acoustic. I'm thinking about using this
room to track drums for my new album. Would you advise recording there,
or would the acoustic just be too overbearing? I want a clean,
natural‑sounding recording for a folk band, so I was thinking this room
might offer the right sort of character.

SOS Technical Editor Hugh Robjohns replies: The limiting factor with
most home project‑studio drum recordings is a combination of a generally
dead‑sounding space, with little in the way of diffuse reflections, and
a serious lack of height, which prevents the overhead mics being placed
optimally. What you tend to get is a strong (but not diffuse) early
reflection from the ceiling, which tends to degrade the quality of the
sound captured — not only of the overheads, but sometimes the close mics
too — and doesn't contribute in a nice way to the drum sound. The only
solution is to make the recording space as dead as possible and then add
artificial reverb to inject some life back into the drum sound, but the
source often still sounds coloured and unrealistic.
A reverberant space often works well with drums because the diffuse
early reflections add a welcome presence and scale to the drums without
overpowering the direct sound. But typically we're talking about
a modestly sized reverberant space here — a stairwell, for example — so
that the early reflections are strong and the reverb time not excessive.
Recording in a typical parish church will provide the benefit of
a very high ceiling, but most also have pretty lively acoustics with
relatively long reverb times. This kind of acoustic character works well
with some kinds of instruments and genres, but it's not a sound
character I generally associate with folk music, which usually requires
a more intimate treatment. All is not lost, though, and the benefits of
the large space can still be used to your advantage if you are prepared
to spend some time and effort controlling the acoustics and
experimenting to optimise the arrangement.
The first thing to do is identify a suitable recording location
within the church. Setting the kit up in the middle of the nave is
probably not going to work: you'll need somewhere more enclosed to
generate some strong early reflections. An entrance porch or a vestry
might provide a more appropriate acoustic, or perhaps setting up in the
aisle between the choir stalls.
Once you've found somewhere that produces the right kind of early
reflections, you'll probably have to try to tame the long reverb tails,
and that will come down to the use of carpet and drapes. Suspending
large duvets from hired‑in lighting stands will make a worthwhile
difference if you experiment with their placement around the kit, to
help shield the overhead mics, in particular, from the worst of the long
reverbs. Remember that a cardioid mic is most sensitive to sounds from
in front and around the sides, so rig the duvets (or whatever) in front
and to the sides of these mics to try to stop reflected sounds from
being picked up.
The low-frequency end of the reverb will be the most difficult to
control — drapes and duvets won't do much at all — so be prepared to
high‑pass filter the mics (especially the overheads) to reduce any
tendency to boominess and muddiness!
Close‑miking will obviously provide the best direct/reverberant sound
balance, and you can mix in one or more 'space' mics set up further
down the church to bring a more reverberant quality to the balance.
Compressing the 'space' mics quite heavily and mixing them in at a low
level often works well.
Judging the subtleties of a miking situation like this on headphones
is very tricky, so my approach would be to do an experimental setup and
recording: multitrack each mic and try out several alternative
techniques. Document everything carefully with measurements, photos and
whatever else you need to be able to recreate the setups later. Then
take the recordings back to your studio, experiment with balancing the
mics and listen critically to see what works and what doesn't.
You can then either go back and experiment more to further optimise
the setup, or if you find one of the arrangements delivers the sound you
want, simply go back and record the tracks using the best rig from your
experimental recordings.
