What is a polar response pattern?
A polar pattern graph shows the variation in sensitivity as you move 360 degrees around the microphone. There are a number of different directional patterns available. The three most common patterns are omnidirectional, unidirectional, and bidirectional. Omnidirectional microphones have equal response at all angles.
What is omni polar pattern?
An omnidirectional polar pattern picks up sound in a 360-degree radius – it is equally sensitive to sound at all angles. Imagine its pattern as a perfect sphere in three directions. This makes omnidirectional microphones ideal for studio recordings where the objective is a natural, open sound.
What is supercardioid used for?
A supercardioid provides better isolation from room noise and nearby instruments and can be more resistant to feedback than a cardioid mic, but it requires the user to maintain a more consistent position directly in front of the mic.
What are the different types of polar patterns?
What are the four polar patterns?

What is microphone gain?
Microphone gain increases the amplitude of a microphone signal. Gain boosts signal strength from mic level to line level, so the microphone signal is compatible with professional audio equipment. Mic preamps control gain and are the first circuits a signal passes through after the microphone output.
What mics are supercardioid?
Hypercardioid Microphone Examples
- Neumann KM 185.
- Beyerdynamic M 160.
- Audix D4.
- Audio-Technica AT4053B.
- Earthworks SR40V.
What does supercardioid mean?
Supercardioid. A supercardioid mic has a tighter pickup angle than a cardioid, but unlike the cardioid, it offers more side rejection. It is, however, slightly sensitive to sound sources that are directly behind the mic.
What is the difference between the supercardioid and cardioid patterns?
Two of these are the supercardioid and hypercardioid. Both patterns offer narrower front pickup angles than the cardioid (115 degrees for the supercardioid and 105 degrees for the hypercardioid) and also greater rejection of ambient sound.
What is cardioid polar pattern?
Cardioid (kar-dee-oid) is the most common directional polar pattern, with the highest sensitivity to sound coming in from directly in front of the microphone capsule (0º), practically no sensitivity to sound coming directly from behind (180º), and a reduced sensitivity to sound coming in from the sides (90º/270º).
What is a hypercardioid pattern?
Hypercardioid Polar Pattern. As such, a hypercardioid microphone is used mainly in loud environments where ambient noise needs to be blocked out. Because the pickup zone is so narrow and it picks up more sound from the rear than other cardioid mics, special care needs to be taken with mic placement. More info on this pattern here.
What is a supercardioid pickup pattern?
A polar pattern name used to describe the pickup pattern of some microphones. The supercardioid pattern is very similar to, and often confused with, the hypercardioid pattern. The supercardioid pattern is slightly less directional than the hypercardioid pattern, but the rear lobe of sensitivity is also much smaller in the supercardioid.
