Every sound engineer hits this wall: pick up a new mic and see “cardioid,” “hypercardioid,” “omni”—but what does that mean for your recording? Polar patterns aren’t just technical labels; they control what your mic hears and what it ignores. Pick wrong, and you’ll capture room noise, feedback, or a muddy mix. Get it right, and you’ll have focus, clarity, and control. This is the guide that’ll finally connect the science to the sounds you actually want.
As detailed by the Podcast Engineering School, the three most common patterns are the Cardioid, which focuses sound pickup directly from the front (0°) while rejecting sound from the rear (180°), making it the optimal choice for isolating single voices or resisting feedback on stage; the Omnidirectional pattern, which captures sound equally from all directions (360°), providing a natural, open sound but lacking noise rejection, making it best suited for controlled studio settings or picking up a choir; and the Bidirectional (or Figure-8) pattern, which accepts sound equally from the front and back while having high rejection from the sides (90°/270°), making it ideal for face-to-face interviews with a single mic
Breaking Down the Main Polar Patterns
- Omnidirectional: Think “360° sound.” Omni mics capture audio from every angle around the capsule. Great for choirs, room ambience, or situations where you don’t want to “point” the mic—but they also grab every cough, squeak, and reverb.
- Cardioid: The workhorse. These mics hear what’s right in front, and reject most noise behind. Perfect for vocals, drum close-miking, or any source you want isolated from the room.
- Supercardioid & Hypercardioid: Tighter focus than classic cardioid, but with little bits of “pick-up” at the rear. They excel at snare drums on loud stages or solo vocals in live settings—just watch rear monitor placement for feedback.
- Figure-8 (Bidirectional): Picks up front and back, ignores the sides. Use for duets, stereo room setups, or recording both singer and instrument from one spot.
Real-World Uses – What Each Pattern Is Built For
| Pattern | Best For | Why Use It | Watch Out For |
| Omni | Choirs, ambient miking | Natural, balanced room sound | Feedback, noisy spaces |
| Cardioid | Vocals, drums, broadcast | Locks to the source, little rear bleed | Off-axis color change |
| Hypercardioid | Snare, lead, guitar amps | Major noise rejection, pinpoint focus | Rear pickup spots |
| Figure-8 | Duets, MS pair, side mic | Stereo tricks, clear front & back | Needs isolation sides |
