6 Microphone Pickup Patterns Every Audio Engineer Should Know [1]
If you asked the average person what a microphone does during the audio production process of filming, they would probably answer that they pick up sound. And, while this is true, anyone who has attended an audio engineering school in Maryland will tell you that there are many types of microphones, each with different features and functions.
And, since your film is only as good as your audio, anyone enrolled in an audio production school should pay close attention to the different microphone types and their pickup patterns.. Today we will look at the major types of microphone pickup patterns that any good videographer should know
Microphones are typically broken into two major (sometimes three) types of pickup patterns before they are described on an individual level. These categories represent the microphone’s sensitivity to various sounds and the direction from which the sound is coming
Microphones. Pickup polar patterns : cardioid, hypercardioid, subcardioid, supercardioid. omni [2]
Eminence has announced Omega Pro 2KW speakers, a series of high power transducers that starts with Omega Pro 12-2KW-8 and the Omega Pro 15-2KW-8.. Featuring an inside/outside 4″ fibreglass coils and , the 12-2KW-8 (12″) and 15-2KW-8 (15″) are reportedly able to get low in small vented..
In practice, the actual patterns often deviate slightly from theory. For example, variations between the polar graphs for different frequencies of a cardioid microphone will be observed.
This microphone picks up sound equally from all directions.. This pattern is named after the shape of an idealized heart (in 3D it would look like an apple)
DIRECTIONAL VS. OMNIDIRECTIONAL MICROPHONES [3]
This article list all the performance-related differences that exist when comparing omnidirectional and directional microphones.. Many engineers are afraid of using omnidirectional microphones in a multi microphone setup with several musicians or sound sources
A cardioid may be the right choice, but often an omni would give a better performance, because of its sonic qualities, low handling-, wind- and pop-noise and lack of proximity effect.. Furthermore, the “leakage” in a DPA omnidirectional microphone will sound more natural
All DPA Microphones – directional and omnidirectional – have an extremely smooth and natural off-axis response. The microphone will not only sound good on axis but also off-axis
Polar patterns: Understanding different microphone pick up patterns [4]
A microphone’s ‘polar pattern’ or ‘pick up pattern’ defines how sensitive the mic is to sounds coming from different directions. No matter what type of mic you’re using, whether it be condenser, dynamic or ribbon, your mic has a polar pattern.
Which polar pattern to use and when depends on a number of different factors.. In this lesson, we’ll look at the most commonly used pick up patterns in audio recording
A cardioid pick up pattern, also referred to as a unidirectional pattern, is most sensitive to sounds in front of the mic. It is less sensitive to sounds at the sides of the mic and it rejects sounds from the rear
What are Microphone Polar Patterns — And Why They Matter [5]
What are microphone polar patterns? If you don’t work in the audio field, then the term may be completely unfamiliar to you. Having a working knowledge of polar patterns, also known as pickup patterns, is crucial when it comes to choosing the best microphone or microphones to use for a specific project
We will define the overall term first, then get into the specifics of each pattern type. If you come across any other terms that are unfamiliar to you, our ultimate guide to filmmaking terminology is a helpful resource for looking things up.
These patterns can be visualized in three-dimensional space. Different microphones have different polar patterns, and these patterns play a role in determining their best uses.
Microphone Pickup Patterns and How They Affect Recording [6]
One of the most important factors determining how a microphone will sound is its pickup pattern. All mics have microphone pickup patterns (also known as polar patterns) even if they’re not an advertised feature that you’re made aware of
Learning the difference between microphone polar patterns and how to find the best pattern for your needs is crucial for giving yourself the highest audio quality possible. The basic differences are easy to spot and remember without being a recording engineer!
When discussing microphone pickup patterns, we are discussing the directionality of a microphone. This refers to which direction a mic will record sounds from relative to itself.

Mic Pickup Patterns [10]
Whether you’re an amateur, semi-professional, or a seasoned pro, you’ll definitely want to have at least one type of microphone in your arsenal. Even if you’re recording an instrument, no digital simulation or piezo pickup will be able to replicate the genuine feel of an actual microphone
With this in mind, we’ve decided to write a guide explaining all of the different types of mic pickup patterns.. If you’re just getting your feet wet in audio, you’ve probably stumbled upon talks here and there about mic pickup patterns
It shows how sensitive microphones are in picking up sound waves from various directions. You’ll also hear the term “polar pattern” which means essentially the same thing.
Microphone Polar Patterns: Which Mic to Choose & How to Use [11]
– Microphone polar patterns determine the area a mic will focus on when recording sound.. – Each polar pattern has its own specialised use cases
– The most common microphone polar pattern for podcasters (or anyone talking into a mic) is Cardioid.. – Other common polar patterns are Subcardioid, Supercardioid, Hypercardioid, and Bi-directional.
Before buying or using a mic, it’s a good idea to find out if it’s the best tool for the job. There are loads of great microphones on the market these days – but the perfect model for a touring musician is going to be a lot different for, say, someone who narrates audiobooks.
A Brief Guide to Microphones – What’s The Pattern? [12]
Omnidirectional Polar Pattern | Directional Polar Patterns | Polar Pattern Considerations | Distance Factor | Sound Characteristics | Selecting a Polar Pattern | Line Microphones | Proximity Effect | Feedback. In addition to classifying microphones by their generating elements, they can also be identified by their directional properties, that is, how well they pick up sound from various directions
To help you visualize how a directional microphone works, you will find polar patterns in our literature and spec sheets. These round plots show the relative sensitivity of the microphone (in dB) as it rotates in front of a fixed sound source
Omnidirectional microphones are the simplest to design, build and understand. They also serve as a reference against which each of the others may be compared
10.2.2: Polar Patterns [13]
The polar pattern (sometimes called the pick-up pattern) of a microphone is the sensitivity to sound based on the direction from which the sound is coming. It is the direction from which microphones are best able to hear sound.
The microphone does not need to face the sound source and is common in lavalier microphones that are used in news programs and during interviews.. The shape of the cardioid polar pattern is similar to the shape of a heart (See figure 10.2.2.2)
Supercardioid mics are similar to cardioid mics, but are more directional to the front of the mic and can pick up sound that is close to the bottom of the microphone (See figure 10.2.2.3).. Hypercardioid mics are similar to supercardioid mics but have more ability to pick up sounds at the bottom of the microphone (See figure 10.2.2.4).
The Complete Guide To Microphone Polar Patterns – My New Microphone [14]
The polar pattern (along with frequency response) is the most important specification of a microphone. It tells us the directional sensitivity of the microphone
Here is a list of all the microphone polar patterns:. In this complete guide, we’ll discuss what polar patterns are, how these patterns are achieved in microphones; and we’ll take a deep look into each of the polar patterns with mic examples.
As with most in-depth guides, a table of contents is highly beneficial:. – Microphone Polar Patterns Are Frequency-Dependent
Microphone Polar Patterns – Everything You Need to Know [15]
When browsing for a new studio condenser mic or live vocal mic, you will run into a specification called ‘Polar Pattern’. This will be accompanied by terminology such as ‘Cardioid’, ‘Omnidirectional’ or ‘Bidirectional’ to name a few.
Simply put, the Polar Pattern determines at what angle from the microphone capsule sound is able to be picked up and is represented in the familiar circular chart format.. Each polar pattern has a specific application – both live and in the studio – that helps you to record your sound source with the most appropriate pattern available depending on the situation
Certain polar patterns are better for recording singing, drums, guitar, or even live performances. By selecting the right pattern for the job, you could save yourself a lot of work down the line in the mixing stage of your productions.
How To Choose The Right Microphone Polar Pattern For Recording – FuelRocks [16]
There are three main types of microphone polar patterns: omnidirectional, cardioid, and bidirectional. Each pattern picks up sound differently, so it’s important to choose the right one for your needs
This makes them ideal for recording acoustic guitars, because they capture the full sound of the instrument. Cardioid microphones are more directional, picking up sound primarily from the front and sides
Bidirectional microphones pick up sound from the front and back, but not the sides. This makes them ideal for recording two guitars at once, or for capturing the sound of a room
What Are Microphone Polar Patterns? The Ultimate Guide • Filmmaking Lifestyle [17]
Mic polar patterns are the pattern of directional gain that your microphone will produce when recording sound at different distances from the mic.. They can be used to determine if you have an omni-directional, unidirectional or bidirectional microphone in front of your instrument.
They will pick up all sounds equally well from all directions, which is why they’re great for ambience recordings and background vocals.. They are widely used by musicians and sound engineers, as well as in recording studios.
Microphone polar patterns are the way that a microphone captures audio from a source.. Polar patterns are complex shapes that vary depending on where you’re pointing the microphone, which is why there are so many different types of polar patterns for microphones.
What are microphone polar patterns, and how do they work? [18]
Understanding the different types of microphone polar patterns and how to apply them is crucial when choosing the right microphone, whether you’re recording vocals, guitars, or a full orchestra.. Your microphone’s polar pattern determines how much of a signal your microphone will capture from different directions.
Picture a 360° field around the microphone; 0° refers to the front of the microphone, while 180° refers to the rear.. Embedded within the 360° circle surrounding the microphone are progressively smaller circles, each indicating a decrease in sensitivity by 5 decibels (dB).
This is usually the go-to polar pattern when recording vocals or individual instruments such as guitars, brass, and drums.. Having its directionality focused in the front allows the microphone to focus solely on the performer and reject any unwanted background noise.
Multi-Pattern Microphones: What, Where and How? [19]
Looking to isolate sound sources and minimize feedback? This overview of the basic mic polar patterns will help you determine which pattern is right for you.. Is it really a cardioid world? While the cardioid polar pattern is undoubtedly the most often used in live sound applications (after all, the ubiquitous Shure SM57 and SM58® microphones are both cardioid types), there’s a case to be made for models that, with the flip of a switch (or the changing of a head) offer directionality options.
Plus, if you have a limited selection of mics in your locker, a multi-pattern mic is really two mics in one.. Before we get into some specific benefits for the stage and studio, let’s review the basic polar (or pickup) patterns
Often misunderstood, a mic’s polar pattern defines how it responds to sounds coming from different directions. The polar pattern tells you how the mic should be placed to maximize pickup of the desired sound source while minimizing feedback or pickup of unintended sound sources.
Microphone Polar Patterns [20]
A guide to choosing the perfect pick up pattern for your mic. Although most microphones look similar, different polar patterns mean they pick up sound in very different ways.
And others pick up sound from everywhere, no matter where you place the mic.. Each microphone polar pattern has its pros and cons, depending on what you’re recording, where you’re recording it, and the sound you’re after.
Let’s take a look at each microphone polar pattern, starting with the most common type – the cardioid.. This is the heart shaped polar pattern you’ll find on most microphones
Mic Patterns 101 : Aviom Blog [21]
Microphones are an essential part of every sound system, and learning to understand and use their various sonic characteristics is a must for any audio tech—whether you work in a studio or in a live environment. This info is important for singers and instrumentalists as well
Not all mics are created equal; mic manufacturers design their products for different jobs and to respond differently to the sounds around them. One of the most important elements in this is a microphone’s pickup pattern
Unlike our ears, which can be “focused” by our brains to listen only to, say, the piano or the lead vocalist, a microphones “hears” everything. But other times, you want a microphone to pick up only certain sounds
Understanding different microphone polar patterns. [22]
The picking pattern basically enables a mic to pick up sound from different directions. front, a mic can be less sensitive or completely insensitive to other directions
When used wisely, it allows achieving a good amount of noise cancellation from unwanted sources of sound and record only exactly what you need. The typical unwanted sources would include the environmental noise, reflected or reverberated sounds, monitors or loudspeakers and also other performers.
With omni mics, no matter how you twist or rotate them, it will all sound the same. Of course, if you bring such mic closer or farther away from the source of sound, the output level will still vary
Which mic should I use? (Mics Part 1) [23]
Most audio producers and reporters heading into the field will have the basics: a handheld recorder of some kind, a pair of headphones, and one or two microphones.. This is one of the most common questions about field recording and the decision can be confusing
But that’s not always the best way! With a little more info we can make a better choice for the job at hand.. Different mics allow you to work more effectively in various situations
Let’s start by exploring those pickup patterns to ensure we understand them.. – Omnidirectional microphones capture sound from all directions equally
Choosing & Using Microphone Polar Patterns [24]
Choose a mic with the optimum polar pattern for the job, and you’re halfway to capturing a great recording.. A lot of inexperienced recordists reach instinctively for cardioid mics to record just about everything, believing that this pattern inherently captures less unwanted room sound
Although I said ‘various’ patterns there are actually only two fundamental ones: figure‑of‑eight and omnidirectional. All of the others you’ve heard of are derived from these two.
But they behave differently, depending on the design of the capsule around the diaphragm.. If both faces of the diaphragm are open to the air, it’s what we call a ‘pressure gradient’ mic and it will have a figure‑of‑eight polar pattern
What is an Omnidirectional Microphone, And How Does It Improve Your Recordings? [25]
If you’re looking for a superior in-person focus group solution, one of the first things you should consider is the type of equipment utilized in the session. An HD camera is obvious, but what kind of microphone should you use?
Ideally, we would suggest using an omnidirectional microphone to get the best audio quality for your study. In this article, we go in-depth into what an omnidirectional microphone is, how they work, and why you should use them for your in-facility focus groups.
It allows you to hear audio from 360° all around the microphone. For this reason, omnidirectional microphones prove very useful when listening to multiple sounds simultaneously, such as musical instruments or conversations.
A Beginner’s Introduction to Microphone Polar Patterns [26]
When it comes to microphone polar patterns, you’ve most likely heard the following 3 terms a million times:. And why are they SO important when choosing the right mic?
A microphone’s polar pattern is the 3-dimensional space surrounding the capsule where it is MOST sensitive to sound.. – Mic 1 has an omnidirectional pattern – meaning the entire red area is equally sensitive to sound.
– Mic 3 has a cardioid pattern – meaning the green area in front of the mic is most sensitive, the sides are less sensitive, and the rear is ignored.. – Supercardioid – which is like cardioid, but NARROWER, with a small bulb of rear sensitivity.
