Microphone Techniques for
Stereo Recording
Stereo recording using two microphones adds realism
by capturing sound similar to the way that humans hear.
Panning (directing the signals left and right) adds width
and directionality when listening on stereo systems or
headphones.
Tip:
Panning the signals farther apart increases stereo
separation and width. Be careful of panning too far, as it
may result in a hollow sound in the middle of the stereo
field.
① X-Y Coincident Pair
The X-Y technique provides excellent phase
coherency because sound arrives simultaneously at
both microphones.
Placement:
Set up the microphones with the
capsules close together, but not touching. Experiment
with angles between 90 and 120 degrees to capture
the full width of the source.

② ORTF
Developed as a French broadcasting standard, ORTF
technique replicates the spacing and angle of human
ears. It provides a natural, wide sound.
Placement:
Angle the microphones at 110°, with the
capsules 17 cm apart.

③ A/B Spaced Pair
Spaced pair recording can deliver a dramatic stereo
effect because sound arrives at each microphone at a
slightly different time, providing the listener with timing
cues that localize sounds.

Note:
For drum overheads, the snare drum should be
equidistant from each microphone to achieve a tight,
focused sound. Use a measuring tape or piece of string
to verify this distance.
