Match the microphone's pickup pattern to your recording scenario

Some microphones let you choose a polar pattern — the shape and direction of the area the mic picks up sound from — using a physical switch, dial, or companion app setting. Choosing the pattern that fits your situation (solo speaking, multi-person interview, or ambient room capture) has a bigger effect on recording quality than most other settings combined.

What you should know

  • Cardioid: picks up sound mainly from directly in front, rejecting sound from behind — the standard choice for a single person speaking or streaming, since it minimizes room noise and other people's voices.
  • Omnidirectional: picks up sound equally from all directions — useful for a roundtable discussion with multiple people seated around the microphone, or capturing ambient room sound.
  • Bidirectional (figure-8): picks up sound from front and back while rejecting the sides — suited to a face-to-face interview with two people on opposite sides of the mic.
  • Stereo: captures a wider left-right image, useful for music, ambience, or ASMR-style content rather than spoken-word podcasting or calls.
  • Change the pattern using the microphone's physical selector switch/dial or the manufacturer's companion app, and re-test gain afterward since sensitivity can shift slightly between patterns.

Why it matters

Using the wrong polar pattern is a common invisible cause of poor-sounding recordings — an omnidirectional pattern used for solo streaming will pick up far more room echo and background noise than cardioid would, and the fix is a single switch rather than any purchase or software change.

Best practices

  • Default to cardioid for solo podcasting, streaming, and video calls, since it's the most forgiving pattern in an untreated room.
  • Switch to omnidirectional only when multiple people need to be picked up around the microphone and a separate mic per person isn't available.
  • Re-test gain and positioning after switching patterns, since the mic's effective sensitivity and ideal distance can change between modes.

Common problems and fixes

Recording sounds echoey or picks up too much room noise
Switch from omnidirectional or stereo to cardioid if your mic supports it, since cardioid rejects far more off-axis room sound.
Second person in an interview is barely audible
Switch to bidirectional (figure-8) if speaking face-to-face across the mic, or omnidirectional if seated around it, rather than staying on cardioid.

Tips and tricks

  • If your microphone doesn't support multiple patterns, achieve a similar effect for group recording by physically repositioning it equidistant between speakers, or by using a separate microphone per person.

Frequently asked questions

How do I know which polar pattern my microphone is currently set to?

Check for a physical switch or dial (often with icons or labels for each pattern) on the microphone body, or open the manufacturer's companion app if the mic sets pattern digitally rather than mechanically.
