Microphone Polar Patterns: A Complete Guide for Creators, Podcasters & YouTubers
Whether you’re podcasting, streaming, recording music, or filming YouTube videos, you need the right microphone. One of the most overlooked yet critical aspects of mic selection is the polar pattern—the area around the mic that captures sound. Using the wrong polar pattern can ruin your audio by capturing too much background noise or missing the subject entirely.
In this guide, you’ll learn what microphone polar patterns are, how they work, and when to use each type for optimal results.
What Is a Microphone Polar Pattern?
A microphone polar pattern (also called a pickup pattern) describes how sensitive a microphone is to sound coming from different directions. Some mics pick up sound evenly from all around, while others are laser-focused on one direction.
Understanding polar patterns can help you:
- Capture cleaner audio
- Minimize room noise or echoes
- Choose the right mic for your recording scenario
Quick Comparison Chart
| Polar Pattern | Picks Up Sound From | Best For | Avoid When… |
|---|---|---|---|
| Omnidirectional | All directions (360°) | Group discussions, ambient audio | In noisy or echo-heavy environments |
| Subcardioid | Mostly front, some sides | Natural vocal recording | High-noise spaces |
| Cardioid | Front only | Solo podcasting, voiceovers | Sound sources are behind the mic |
| Supercardioid | Front + slight rear | Studio voice work, narration | Rear noise sources are present |
| Hypercardioid | Narrow front, rear lobe | Noisy rooms, on-location shoots | Rear reflections or noise exist |
| Bi-directional | Front & back | 2-person interviews (face-to-face) | Side noises are prevalent |
| Shotgun | Extreme front focus | Film sets, vlogging, outdoor audio | Indoors with hard reflections |
In-Depth: Microphone Polar Patterns Explained
🎧 Omnidirectional
- How It Works: Captures sound evenly from all directions.
- Best For: Group conversations, lavalier mics, ambient sound capture.
- Downside: Can pick up unwanted background noise and room echo.
🎙 Subcardioid
- How It Works: A softer directional pattern than cardioid. Wider pickup with more room tone.
- Best For: Natural-sounding vocals with some isolation.
- Downside: Not as focused as cardioid in noisy rooms.
❤️ Cardioid
- How It Works: Picks up sound from the front while rejecting noise from the rear.
- Best For: Solo podcasting, streaming, voiceovers.
- Pro Tip: Great for untreated rooms and reducing background noise.
🎯 Supercardioid
- How It Works: Narrower than cardioid, with slight rear pickup.
- Best For: Close-mic vocals, directional focus in controlled environments.
- Downside: May pick up sound from behind the mic.
🚫 Hypercardioid
- How It Works: Tighter front pickup with more pronounced rear sensitivity.
- Best For: Film shoots, loud environments.
- Downside: Rear noise and reflections may creep in.
🧍↔️🧍 Bi-directional (Figure-8)
- How It Works: Picks up equally from the front and back, rejects the sides.
- Best For: Face-to-face interviews using one mic.
- Downside: Side noise rejection can be too aggressive.
🔫 Shotgun
- How It Works: Very narrow front pickup, excellent for distance capture.
- Best For: Outdoor interviews, film shoots, stage audio.
- Downside: Poor performance indoors unless acoustics are controlled.

Which Mic Polar Pattern Should You Use?
| Scenario | Recommended Pattern |
| Solo podcasting | Cardioid |
| YouTube tutorial voiceover | Cardioid |
| Face-to-face interview (1 mic) | Bi-directional |
| Group talk (1 mic) | Omnidirectional |
| Filming a vlog outside | Shotgun |
| Recording in a noisy room | Hypercardioid |
| Natural sounding vocals (roomy) | Subcardioid |
Final Tips for Better Audio
- If you’re unsure what mic to get, start with a cardioid USB mic.
- Always point your mic correctly: even great polar patterns fail when aimed poorly.
- Don’t share mics unless you’re using a pattern designed for it (like bi-directional or omni).
- Treat your room or use close-mic techniques to reduce echo and reverb.
Frequently Asked Questions
Q: Can I switch polar patterns on my microphone?
A: Only if it’s a multi-pattern mic. Examples include the Blue Yeti, Audio-Technica AT2050, or Rode NT2-A.
Q: My mic sounds distant and echoey. What’s wrong?
A: You might be using an omnidirectional setting in a reflective room. Try switching to cardioid and getting closer.
Q: What does “proximity effect” mean?
A: Directional mics like cardioid boost low-end frequencies when you’re very close. This can be used creatively, but it may also cause muddiness.
