Six polar patterns, six completely different personalities. Confuse them, and you’ll find yourself cursing at your monitor. Understand them, and you’ll suddenly get so much more out of the same mic.

You buy a microphone for its sound, naturally. But in practice, its polar pattern plays just as big a role in how your mix turns out. That little icon on the box—the heart shape or the circle, tells you exactly one thing: which directions the mic "listens" to, and which ones it prefers to ignore.

And that act of ignoring? That’s where the magic lies. A microphone doesn’t actually make any sound louder; it simply chooses what to capture and what to reject. The better that choice suits your situation, the less you’ll have to rely on EQ, gates, and prayers to salvage the sound later. The best part is, you don’t have to take our word for it: slowly rotate a mic while the PA is running, and you’ll hear for yourself exactly where it’s "deaf."

Let’s run through the family, from the most "sociable" to the most "antisocial." In each diagram, the orange shape indicates where the mic is sensitive. The red dots mark its dead zones—and those are precisely the spots where your monitor should be placed.

The omni picks up sound from all directions at roughly the same level. No preference, no judgment.

That might sound dull, but it is precisely its strength. An omni pattern generally produces the most natural sound there is: sound arriving from the side or rear sounds exactly as it should—just a bit quieter due to the distance. It also lacks the proximity effect, so your speaker can move around without the low end going haywire. Plus, it typically extends deeper into the bass frequencies than its directional counterparts.

Use it for: ambient and venue recordings, classical music and choirs, lavalier mics and headsets, measurement microphones, and drum room mics.

Note: on a loud stage, an omni is an invitation to feedback. It picks up your monitors just as readily as it does your singer.

Also known as "wide cardioid." It sits halfway between omni and cardioid: offering a broad, forgiving pickup pattern at the front, with about 8 dB of attenuation at the rear rather than total rejection.

You get much of the natural sound of an omni, combined with a bit more control. It remains nicely neutral off-axis, and the proximity effect stays manageable.

Use it for: choirs and acoustic ensembles, podcast setups where people move around, or overheads where you actually want to capture some of the room sound.

Note: it is a compromise—and that is the point. Don't expect miracles on a loud stage.

The heart-shaped pattern: maximally sensitive at the front, dead silent at the rear. This is the pattern found on virtually every legendary live vocal microphone.

One simple rule suffices. Point the mic at what you want to capture, and make sure what you don't want is positioned behind it. That is the easiest rule of thumb in the entire world of audio.

Use it for: live vocals, speakers, guitar cabinets, toms, and snare drums—anything where speed is of the essence.

Note: the proximity effect is pronounced. That’s not a flaw; it’s a tool. Singers who tour with their own mic are constantly adjusting their own EQ.

Even narrower at the front, an even larger rear lobe, and null points around 110 degrees. Among the classic patterns, the hypercardioid offers the highest directivity.

In practical terms, this means you can place it about twice as far from the source as an omni while maintaining the same ratio of direct sound to room sound.

Use it for: drum overheads and hi-hats on a crowded stage, horn sections, guitar cabinets positioned close together, and broadcast applications in noisy environments.

Note: that narrow front pickup leaves no room for error. Being off-axis by just two centimeters is immediately audible. And remember: the rear lobe is real.

The shotgun (or lobar) microphone operates using an interference tube: sound arriving from the side enters through perforations in the tube at varying times, causing phase cancellation. The result is an extremely narrow main lobe flanked by small side lobes.

Important: a shotgun microphone is not a zoom lens for sound. It does not make the source louder; it makes the background quieter. If you are too far away, you will simply end up with a quiet recording that also suffers from noise.

Use it for: film and documentary, ENG and broadcast, sports, and nature recording, any situation where the microphone needs to remain out of sight.

Note: the tube only functions above a certain frequency, determined by its length. Below that frequency, it behaves like a hypercardioid microphone. Indoors, in a small room with hard surfaces, sound reflects from all directions, precisely where the microphone sounds its worst off-axis.
