Polar Patterns

CARDOID


Cardoid is what is the microphone that is used for vocals. The music is picked up by the sound around the head of the mic. When a singer or stand up comedian get on stage they want a microphone what picks up there voice & nothing else, so the cardoid microphone is what they use to do this.


FIGURE OF 8


Figure of 8 is another type of polar pattern used with microphones. This is also used for vocals, however instead of being used for one person & solo artists, it's used for two people & duets. The microphone picks up sound from the right & also sound from the left, they then meet in the middle to create sound of a stereo effect. This pattern means that only the voices of the two people in the duet are getting picked up & others around them are not.


OMNI


Omni creates ambience which is the french word for atmosphere. It is used to record sound effects of say a jungle for the Endor Forest in Star Wars. This means this pattern allows you to pick up all the sound around you. This technique is used mainly in the film industry & very little elsewhere.


UNI


Uni microphones pick up sound in one direction. These are used to record sounds in film s through a boom pole to pick up actors & actresses sounds in a noisy scene. These microphones are used most for interviews as you only need to hear the subjects voice.
