Polar Patterns

The polar pattern of a microphone refers to the direction or directions in which it
picks up sound. Some microphones are a fixed single pattern (usually cardioid)
while others offer the ability to switch between multiple patterns. When using a
multipattern mic, it is always a good idea to experiment with different patterns
not only for different directional characteristics but also for tonal variations. Here
are descriptions of 4 basic and common polar patterns.
Cardioid
Figure 8
Omnidirectional
Hypercardioid
Note: Proximity effect refers to an increase in low frequency pickup as the source
is moved closer to the microphone, typically within a 2 ft range.
Picks up sound from the front and sides of the microphone
with good rear rejection. Exhibits proximity effect.
Picks up sound from the front and back of the microphone
with good side rejection. Exhibits maximum proximity effect.
Picks up sound from all directions. Exhibits no proximity
effect.
Like cardioid with more rejection on the sides, less rear
rejection and more proximity effect.
