Polar pattern basics
A polar pattern describes where a microphone is most sensitive. It is not the same as automatic noise cancellation.
Cardioid
Cardioid microphones focus on the front and reject more from the rear. This is the common choice for solo voice.
Omnidirectional
Omnidirectional microphones pick up sound from all directions. They can be useful for lavaliers and room capture but are less focused.
Bidirectional and shotgun
Bidirectional mics capture front and back. Shotgun mics are directional tools for video placement and should still be close to the subject.

Frequently Asked Questions
What polar pattern is best for podcasting?
Cardioid is usually best for solo podcasting because it focuses on sound from the front of the microphone.
Does a polar pattern block all background noise?
No. It changes pickup direction, but distance, gain, and room sound still matter.
