University Sound US664A dynamic supercardioid microphone. The most common unidirectional microphone is a cardioid microphone, so named because the sensitivity pattern is "heart-shaped" (i.e. a cardioid). The cardioid family of microphones are commonly used as vocal or speech microphones since they are good at rejecting sounds from other directions.
Typically, an array is made up of omnidirectional microphones, directional microphones, or a mix of omnidirectional and directional microphones distributed about the perimeter of a space, linked to a computer that records and interprets the results into a coherent form. Arrays may also be formed using numbers of very closely spaced microphones.
The output impedance is user-selectable; factory preset at 250 ohms, and changeable to 30 or 150 ohms. The microphone has a fairly flat response. In the cardioid (unidirectional) pattern, it is level from approximately 150 Hz to 2 kHz, with a slight rise peaking at just under 5 kHz, then dropping approximately 3 dB/octave to 20 kHz. [5]
When concealing the mic is important, such as with film production, a smaller housing may be desirable. Sanken's CUB-01 boundary microphone has a 32 mm diameter and 12 mm height, which makes it easier to hide in TV and film field shooting and easier to reposition or temporarily mount in locations (e.g. taping it onto the inside ceiling of a car).
Well, we used to have a thing called a Decca Tree which was an arrangement where [at] the front edge of an orchestra about 3.2 metres up in the sky you would have a centre microphone roughly in line with the edge of the orchestra, and then maybe 2.5 feet back and 5 feet apart you would have 2 more forming a triangle, omnidirectional microphones.
Omnidirectional microphone, a microphone that can hear from all directions; Mecanum wheel, a specially designed wheel that allows movement in any direction, such as that used by many robots in the RoboCup Small Size League; Wingless Electromagnetic Air Vehicle, an electrically operated vehicle that can fly in any direction
The Soundfield microphone is an audio microphone composed of four closely spaced subcardioid or cardioid (unidirectional) microphone capsules arranged in a tetrahedron. It was invented by Michael Gerzon and Peter Craven, and is a part of, but not exclusive to, Ambisonics, a surround sound technology. It can function as a mono, stereo or ...
