Selecting the appropriate microphone is crucial when it comes to audio recording and broadcasting. Omnidirectional microphones are unique among the various kinds of microphones because they can record sound equally from all directions. In addition to discussing their benefits and contrasting them with unidirectional and cardioid microphones, this page will provide an answer to the query, “What mics are omnidirectional?”
What Are Omnidirectional Microphones?
The purpose of an omnidirectional microphone is to capture sound equally from the front, rear, and sides. Omnidirectional microphones offer balanced audio in all directions, in contrast to directional microphones, which concentrate on recording sound from a particular area.
