What is shotgun microphone?
What is shotgun microphone?
A type of microphone characterized by an extremely directional polar pattern. Shotgun mics may be condenser or dynamic, but are almost always built with a long (8 to 24 inch) tube protruding from the front. Shotgun mics are sometimes called Line Microphones.
Why is it called shotgun mic?
The shotgun microphone is named for the long, slotted tube in front of the microphone cartridge that makes it resemble a shotgun. This “interference tube” helps reject sounds coming from more than about 30 degrees off to the sides, while still picking up sounds from the front.
What are shotgun mics best for?
Shotgun mics are great for moving subjects compared to lavaliers. Also, because shotgun mics are typically mounted onto boompoles, you’ll have an easier time recording audio even when your subject is moving.
What is a gun microphone?
• GUN MICROPHONE (noun) Meaning: A highly directional microphone with a long barrel; can be directed from a distance.
What is the difference between a boom mic and a shotgun mic?
Shotgun refers to the polar pattern of the microphone. Shotgun mics are typically a hypercardiod pattern. Boom-mounted shotgun mics let you pick up a focused area, with very little off-axis noise, and their tight polar pattern provides better performances at longer distances than typical condenser microphones.
What is the range of a shotgun mic?
The most expensive shotgun mics can only capture audio from a distance of six to ten feet, while more affordable mics sound their best at a distance of three to four feet away. Interviews are typically shot from about seven to ten feet away from the subject.
What type of microphone is a shotgun mic?
Shotgun microphones fall into a category called “high-directionality microphones.” They are more directional than a typical cardioid or supercardioid microphone.
Do a shotgun mic picking up background noise?
Advantages of shotgun mics Built-in mics are generally not designed for quality audio. They can pick up a lot of background noise and wind, while shotgun mics give you clearer voice pickup. That being said, however, keep in mind that shotgun mics do not “zoom” in on sound the way a camera lens zooms in on actors.
What’s the difference between a shotgun mic and a boom mic?
Is a shotgun mic omnidirectional?
The shotgun mic is like a laser, narrowly focused on one spot.” An omnidirectional mic picks up sounds from all directions equally, so you need to hold it close to your subject if there are competing background sounds. The shotgun mic focuses wherever it is pointed with a narrow and long beam.
What kind of microphone is a shotgun microphone?
A shotgun microphone is a highly directional microphone that must be pointed directly at its target sound source for proper recording. Shotgun microphones use unidirectional microphones to achieve this high beam of concentration on the sound source to record the sound.
What should I be aiming my shotgun mic at?
Another positioning rule to follow is that, if you’re shooting indoors, try to avoid aiming your shotgun mic at hard surfaces. Think hardwood floors or brick walls. These surfaces reflect sound waves that cause the sound to be somewhat hollow and can reduce the effectiveness of the interference tube design.
What does mic stand for in antibiotic susceptibility?
Next to each antibiotic is the susceptibility interpretation: S (sensitive), I (intermediate), or R (resistant), followed by the MIC in μg/mL. Sensitive implies that the organism is inhibited by the serum concentration of the drug that is achieved using the usual dosage; intermediate implies that the organisms are inhibited only
How is MIC used in the field of Microbiology?
Microbiology guide to interpreting minimum inhibitory concentration (MIC) Historically, in vitro susceptibility testing was routinely performed by disk diffusion (Kirby-Bauer) method. The size of the growth-free zone determined whether the bacterium was considered to be susceptible, resistant, or intermediate to a particular antibiotic.
