Microphone Polar Patterns
Another important factor to consider when choosing a microphone for live vocals is the polar pattern. The polar pattern refers to the microphone’s sensitivity to sound coming from different directions. The most common polar patterns are cardioid, supercardioid, and omnidirectional.
Cardioid Polar Pattern
The cardioid polar pattern is the most common and is characterized by its heart-shaped pickup pattern. Cardioid microphones are sensitive to sound coming from the front and reject sound coming from the sides and rear, making them ideal for live vocals where the goal is to capture the singer’s voice while minimizing background noise.
Supercardioid and Hypercardioid Polar Patterns
Supercardioid and hypercardioid microphones have a tighter pickup pattern than cardioid microphones, making them even more effective at rejecting background noise. However, they can also be more prone to picking up sound from the rear, which can be a problem in certain live environments.
Omnidirectional Polar Pattern
Omnidirectional microphones, as the name suggests, pick up sound from all directions equally. While they can be useful in certain applications, such as recording a group of singers or a choir, they are not ideal for live vocals where the goal is to isolate the singer’s voice.
Popular Microphones for Live Vocals
