omnidirectional microphone , auch: omnidirectional mike informal

It can also be converted for use as an omnidirectional microphone.

All of the samples used for production were recorded by himself using an omnidirectional microphone.

Most older hearing aids have only an omnidirectional microphone.

This meant that he had to develop ways of using omnidirectional microphones to record what we now know as stereo sound.

Amateurs are likely to find a pair of omnidirectional microphones the most versatile.

An omnidirectional microphone amplifies sounds equally from all directions.

A matching pair of small-diaphragm omnidirectional microphones is always used with a Jecklin disk.

Omnidirectional microphones are designed to pick up sound equally in all directions; the one on your camcorder may be omnidirectional.

The microphone may be built into the camera, in which case it is an omnidirectional microphone which picks up sound in a very general way.

A Decca Tree setup includes 3 omnidirectional microphones in a "T" pattern.

Curved shape, omnidirectional microphone.

The W channel is the non-directional sound pressure component of the signal, corresponding to the output of an omnidirectional microphone.

Omnidirectional microphones are connected to the console, as well as a TV monitor with loudspeakers and/or a video projector.

Invented by Robert Showen, an electronics engineer, the system consists of eight omnidirectional microphones mounted on rooftops and utility poles.

The technique traditionally uses three omnidirectional microphones, traditionally of the Neumann M-50 small-diaphragm pressure transducer tube condenser type, to record in stereo.

Typically, an array is made up of omnidirectional microphones distributed about the perimeter of a space, linked to a computer that records and interprets the results into a coherent form.

This uses two parallel omnidirectional microphones some distance apart, so capturing time-of-arrival stereo information as well as some level (amplitude) difference information, especially if employed close to the sound source(s).

Usually, the omnidirectional microphone mode is used in quiet listening situations (e.g. living room) whereas the directional microphone is used in noisy listening situations (e.g. restaurant).

Omnidirectional microphones, unlike cardioids, do not employ resonant cavities as delays, and so can be considered the "purest" microphones in terms of low coloration; they add very little to the original sound.

If the speech is in front of the listener and the noise is from a different direction, then compared to an omnidirectional microphone, a directional microphone provides a better signal to noise ratio.

It is also a late-20th-century realization of nearly every child's Erector Set dream: an electric motor, a heavy-duty gripper claw, an extendable arm, a neat speaker and an omnidirectional microphone, all screwed together.

In addition to the standard omnidirectional microphone, the company also sells a directional microphone for recording night flight calls of migrating birds as well a hydrophone that can be attached for monitoring underwater.

In more mathematical terms, while omnidirectional microphones are scalar transducers responding to pressure from any direction, bi-directional microphones are vector transducers responding to the gradient along an axis normal to the plane of the diaphragm.
