Capacitor Microphone Polar Patterns: A Comprehensive Guide

What is Polar Pattern?

A polar pattern (or pickup pattern) describes how sensitive a microphone is to sounds arriving from different angles relative to its central axis. Think of it as a “sound reception map” that determines where the microphone “listens” and where it “doesn’t listen.” Understanding polar patterns helps you position your microphone wisely—maximizing the target sound source while minimizing unwanted noise.

Why Polar Pattern Matters

Choosing the wrong polar pattern can be more critical than choosing the wrong microphone. It directly affects three things: whether the sound is clean (can it isolate the target and reject ambient noise?), the sense of space (how much room reverb is captured?), and your mic placement strategy. Simply put: polar pattern determines the “sound world” you record.

Main Polar Patterns for Capacitor Microphones

1. Cardioid

Characteristics: Most sensitive at the front (0°), attenuated on the sides, and strongly suppressed at the rear. The name comes from its heart-shaped contour on a polar coordinate chart—professionally, it’s always written as “Heart shape” (shape), not “Heart shape” (type).

Pros: Strong noise rejection, reduces environmental interference, most widely used.

Cons: Exhibits proximity effect (bass boost when close), sensitive to placement.

Best for: Vocal recording, live streaming/podcasting, stage performances, solo vocals.

Cardioid is the most popular styles, we have many DIY condenser microphone is cardioid style.

2. Supercardioid

Characteristics: Narrower forward pickup angle than cardioid, stronger side suppression, but with a small rear pickup “tail lobe.”

Pros: Stronger source isolation, more effective at suppressing side noise, higher direct-to-reverberant ratio for clearer sound.

Cons: The rear tail lobe can pick up unwanted sounds; requires stricter aiming—slight deviation degrades performance; can create unnatural spatial sense if misused.

Best for: Live stage performances, film/TV field recording (boom mics), situations requiring strong noise rejection.

3. Omnidirectional

Characteristics: Equally sensitive to sounds from all directions (360°).

Pros: Captures the full frequency range evenly, ideal for capturing room ambiance.

Cons: No rejection of environmental noise—every sound in the room is picked up equally.

Best for: Lavalier mics on singers who move around, conference mics where everyone speaks from different positions, capturing entire acoustic environments.

4. Figure-8

Characteristics: Equally sensitive to front and rear sounds, with almost no pickup from the sides. Also called bidirectional.

Pros: Excellent for isolating two sound sources positioned front and back.

Cons: Picks up everything from the rear—room noise behind the mic is just as audible as the target.

Best for: Two-person dialogue or interviews (speakers facing each other), face-to-face vocal duets, stereo recording techniques like Blumlein pair.

Quick Comparison Table

Pattern	Front	Sides	Rear	Best For
Cardioid	★★★	★★☆	✗	Solo vocals, podcasts
Supercardioid	★★★★	★☆☆	△ (tail lobe)	Stage, field recording
Omnidirectional	★★★ (all directions)			Ambience, conferences
Figure-8	★★★	✗	★★★	Duets, interviews

Final Thoughts

The right polar pattern isn’t about finding the “best” one—it’s about matching the pattern to your environment and goal. In a treated studio? Cardioid or figure-8 will serve you well. On a noisy live stage? Supercardioid gives you the isolation you need. Want to capture the room itself? Go omnidirectional.
