Years ago, I was second engineer on
a Christian project where one of the
musicians was buddies with a famous
engineer who had worked with Eric
Clapton and tons of other big stars.
This guy—who was donating his time
to the church as a favor to his friend—
had his name on quite a few of the
’60s and ’70s records I loved, and I
was pretty jazzed to watch him work.
But I was more than a little
disappointed when he touched just
three things the entire session: a single
Shure SM57 microphone, the volume
fader, and the Record button.
His fingers never twisted the EQ
knobs. He didn’t glance at the racks
crammed full of sexy compressors,
limiters, de-essers, and noise gates.
He didn’t ask to rummage through
the mic cabinet. He didn’t seem to do
much of anything at all. And yet, his
tracks sounded . . . amazing. This was
my first hardcore lesson on the critical
importance of mic placement.
Freedom of Choice
While it’s certainly no crime to subject
input signals to all kinds of
manipulation via compressors, EQ
units, and other processors, it’s also
not a bad move to document sound
more organically. For one thing, capturing
signals flat can ultimately produce
cleaner and more robust
sounds, because you’re not sending
the signals through the EQ circuitry
twice—once when tracking, and again
while mixing.
Now, it may seem nutso in a DAW
and plug-in obsessed culture to maintain
that modern, pro-quality sounds
can be crafted without resorting to
EQ tweaks, but I’ve seen it done so
I’m a believer. If you’re willing to
abandon processing for a spell, here’s
how you can record great-sounding
tracks by simply moving a
microphone.
Protect the Environment
Step number one is ensuring your
recording space is up to the task of
delivering good sound. Walk around
the area where you plan to record the
instrument, and clap your hands. If you
hear flutter echoes, edgy slapbacks,
weird boinks, or other anomalies,
either put up some absorptive materials,
or choose another place to record.
When you believe you’ve found the
perfect spot, confirm it by placing a
mic where your ears are, and having
the musician play. If you hear
everything clearly and naturally,
call “Bingo.” If you can still hear
annoying echoes, metallic-sounding
reflections, or any resonances
that make you wince, then keep
searching. Few home environments
are perfect, of course, but attempt to
find the space that serves up the most
natural sounds with the least amount
of compromises.
Mic Positioning Is All
About the Ears
Les Paul used to say that if a player
didn’t have good ears, he or she
would probably never be a professional
musician. It’s kind of the same
with mic placement. You have to be
able to hear minute differences in
detail and tone as you move a mic
around a source sound. It helps to
know what type of sound you’re looking
for—or, at least, to know it when
you stumble upon it. Happily, some
aspects of mic positioning can be
learned through trial and error, even if
your ears aren’t as revved-up as Les’
were. You just need to place the mic
at a starting point, and then learn
where the desired audio events occur.
Let’s use a guitar speaker as an
example. Position the mic dead center
on the speaker cone. I’m sure you
already know that moving the mic
back from the speaker can slightly
diminish lows and low mids, as well as
capturing more air or room tone. But
what if you want more mids or highs?
Does moving the mic toward the
right edge of the speaker do it for
you? How about placing the mic offaxis?
Maybe the best sound is captured
when the mic is pointed at the
top edge of the speaker, or the bottom
edge. The goal here is to find
your bliss. There’s no right or wrong—
just what sounds fabulous to you—so
explore and experiment.
A Vow of Compliance
Moving mics around is obviously not
as easy as using console EQ, so you
have to commit to the process. Tracks
crafted through mic placement may
also sound a bit different than if you
twiddled EQ knobs, and you’ll have to
be the judge as to whether that difference
is desirable, or worth all the
trouble. But you’ll certainly learn volumes
about sound production by
painstakigly repositioning a mic
around a source, and, as a result, your
tracks might just achieve that sonic
gleam that makes them more special
and dimensional than those created
by the knob twisters.
