Best to use when more room ambiance is the goal. Direct and ambient sound can be adjusted by moving the mic closer to or further from the sound source. | Best to use when more room ambiance is the goal.

=== Unidirectional Microphone === | ==== Unidirectional Microphone ==== | ||
Unidirectional microphones are sensitive to sound coming from only one direction. Examples: | Unidirectional microphones are sensitive to sound coming from only one direction. Examples: | ||
* a vocalist singing directly on axis directly into the microphone | * a vocalist singing directly on axis directly into the microphone | ||
* a guitar amplifier with the microphone aimed directly at the speaker cone | * a guitar amplifier with the microphone aimed directly at the speaker cone | ||
==== Cardioid ==== | ===== Cardioid ===== | ||
[[Image:uni_con.gif|left]] The most common type of unidirectional microphone is called a “cardioid” because its pickup pattern is heart-shaped. It picks up most sound from the front of the microphone and some from the sides. | [[Image:uni_con.gif|left]] The most common type of unidirectional microphone is called a “cardioid” because its pickup pattern is heart-shaped.
