What are the six microphone polar patterns used for?
Microphone polar patterns, sometimes called pickup patterns, define microphone sensitivity in different directions. The different polar patterns are used for controlling sound pickup and isolating the sound source, or sources, of primary interest from surrounding sources. There are six common microphone polar patterns: cardioid, supercardioid, hypercardioid, omnidirectional, lobar, and bidirectional. Polar patterns are represented by […]
