The world of audio recording and sound engineering is vast and complex, with numerous types of microphones designed to capture sound in various environments and applications. Among these, the supercardioid microphone stands out for its unique characteristics and versatility. In this article, we will delve into the details of what a supercardioid mic is, its polar pattern, applications, and how it compares to other types of microphones.
Introduction to Supercardioid Microphones
A supercardioid microphone is a type of directional microphone that is designed to reject sound from the sides and rear, focusing on capturing sound from the front. This is achieved through its supercardioid polar pattern, which is a variation of the cardioid pattern but with a tighter pickup area at the front and a more pronounced rejection of sound from the sides and back. The supercardioid pattern is often described as being “tighter” than a cardioid pattern, meaning it has a narrower area of pickup at the front.
Polar Patterns Explained
To understand the supercardioid microphone, it’s essential to grasp the concept of polar patterns. A microphone’s polar pattern refers to its sensitivity to sound waves arriving from different directions. The most common polar patterns include omnidirectional, cardioid, supercardioid, and hypercardioid, each with its unique characteristics and uses.
- Omnidirectional microphones pick up sound equally from all directions, making them suitable for applications where capturing the overall ambiance is desired.
- Cardioid microphones are heart-shaped and primarily pick up sound from the front, rejecting sound from the rear. They are widely used in live performances and public speaking events.
- Supercardioid microphones, as mentioned, have a tighter front pickup area and better side rejection than cardioid microphones, making them ideal for applications where minimizing background noise is crucial.
- Hypercardioid microphones have an even tighter pickup pattern than supercardioids, with the narrowest area of front pickup and the most pronounced rejection of sound from the sides and rear.
Applications of Supercardioid Microphones
Supercardioid microphones are versatile and can be used in a variety of applications, including:
Supercardioid microphones are particularly useful in live sound applications, such as concerts and theater performances, where they help to isolate the sound of the performer or speaker from the background noise of the audience or other instruments.
