Directional microphones are designed to capture sound from specific directions while minimizing noise from other angles. This feature makes them ideal for situations where clear audio is needed, such as in film production, live performances, or interviews. They often come in various types, including cardioid, supercardioid, and hypercardioid, each with a different pickup pattern. These microphones work by using multiple sound entry points to differentiate between sounds coming from the front and those from the sides or back. This technology helps improve audio quality in noisy environments, making directional microphones a popular choice for broadcasting and podcasting.
