A microphone’s sensitivity varies with frequency (as well as with other factors such as environmental conditions) and is therefore normally recorded as several sensitivity values, each for a specific frequency band (see frequency spectrum). A microphone’s sensitivity can also depend on the nature of the sound field it is exposed to.
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.
One complaint was that the RE20 was less suited to soft-spoken people, but the added sensitivity of the RE27N/D solved that problem in the late 1980s. [6] The large size and weight of the RE20 requires a strong microphone stand or boom arm, and a very sturdy microphone clip or robust hanging yoke. The supplied mic clip (model number 320) is ...
The Shure SM58 is a professional cardioid dynamic microphone, commonly used in live vocal applications. Produced since 1966 by Shure Incorporated , it has built a reputation among musicians for its durability and sound, and is still the industry standard for live vocal performance microphones.
The sensitivity pattern of a bidirectional microphone (red dot) viewed from above. In a moving-coil microphone, the diaphragm is attached to a light movable coil that generates a voltage as it moves back and forth between the poles of a permanent magnet. In ribbon microphones, a very thin light metal ribbon (usually corrugated) is suspended ...
This convention is the basis for the ITU's LUFS loudness unit, [23] and is also used in Sound Forge [10] and Euphonix meters, [24] and Analog Devices digital microphone specs [25] (though referred to as "dBFS").

An Alesis Micro Gate noise gate. A noise gate or simply gate is an electronic device or software that is used to control the volume of an audio signal.Comparable to a limiter, which attenuates signals above a threshold, such as loud attacks from the start of musical notes, noise gates attenuate signals that register below the threshold.
