POLAR PATTERN

The directions a microphone hears from — cardioid, omni, figure-8. Choosing it is half of getting a clean vocal in an untreated room.

A studio control room with a DAW session open on screen, monitor speakers and a control surface — the recording and editing setup these production terms describe.

Key takeaways

  • The directions a microphone hears from — cardioid, omni, figure-8.
  • Choosing it is half of getting a clean vocal in an untreated room.
  • Cardioid rejects the rear, omni captures everything equally and picks up more room, figure-of-eight rejects the sides and is the basis of mid/side and Blumlein recording.
  • In an untreated room, a cardioid mic pointed away from the nearest reflective wall reduces room tone before you touch a single panel.
  • Watch out: assuming cardioid is always safest.

Quick checklist

  • Can you define polar pattern in one sentence without looking?
  • Can you point at polar pattern in a real session, mix or contract?
  • Have you tried the practical move above at least once?
  • Would you catch the common mistake before it costs you a take?
  • Have you opened one of the primary sources below rather than a forum thread?

POLAR PATTERN IN DEPTH

A microphone's polar pattern describes which directions it is sensitive to. Cardioid rejects the rear, omni captures everything equally and picks up more room, figure-of-eight rejects the sides and is the basis of mid/side and Blumlein recording.

How it works in practice

In an untreated room, a cardioid mic pointed away from the nearest reflective wall reduces room tone before you touch a single panel.

The mistake people make

Assuming cardioid is always safest. Omni patterns have no proximity effect and often sound more natural on close acoustic sources when the room allows.
