Microphone options for video capture. There are several different microphone options that can be used to capture video. The microphone type selected will depend on the situation and the camera used.
What exactly is a microphone?
A microphone is indeed a gadget that converts airborne sound vibrations into electronic signals as well as records them to a recorder or over a loudspeaker.
Microphones enable a wide range of audio recording devices to be used for a variety of purposes such as communications, music vocals, speech, and sound recording.
The dynamic microphone, the most popular forms of microphone, employs a coil suspended in a magnetism that can be connected to multiple membrane surface for extended carrier frequency.To generate an audio signal, dynamic microphones use electricity in the form of induction. These microphones are ideal for use on stage.
A small diaphragm is connected to something like a moving coil in the microphone capsule. The diaphragm vibrates when sound waves strike it. This causes the coil to oscillate in the magnetic field, producing an electrical current.
However, how well a microphone functions ultimately depends on its intended purpose.
Aside from the device, one of the most important considerations is what is recorded. Another factor to consider in microphone design is the directionality of the microphone.
Wired microphones:
This is the most obvious option, and probably the most reliable. There are several forms of wired microphones that can be used for video.
Handheld Microphone:
These microphones can work well, but are generally not used that much. Often for video interviews an omnidirectional microphones may be used, but sometimes a cardioid microphone may offer good results. These microphones can give good results as they can be brought closer to the speaker to eliminate ambient noise. Handheld microphones tend to have XLR connectors and these normally use fairly thick wire.
A shotgun microphones:
A typical moving coil or dynamic microphone handheld dynamic microphone Gun microphone. A shotgun microphone is a directional microphone that is often designed for use with a camera. Being fairly directional they provide a considerable degree of external noise reduction. Good quality shotgun microphones can also reduce the echo in a room and provide a good solution for many other video and vlogging applications where they can reduce external noise while still offering decent levels of comfort. The shotgun microphone has a characteristic long shape, its maximum response is along the axis of the microphone. Actual directional response depends on actual microphone, but check specifications before purchasing. That said, many will be very good for many applications.

Lapel Microphone:
A lapel microphone or lapel microphone is a small microphone that can be clipped onto the speaker’s clothing at “heart” height. Being close to the speaker means it can perform well for interviews and other applications where people are speaking to the camera. Lavalier microphones are omnidirectional and therefore do not provide optimum noise reduction, but this is not normally an issue as they are so close to the speaker. To reduce the effect of plosive sounds like “p”, “b”. , e.t.c. They can often be tilted downward with the speaker’s mouth, thus relying on the omnidirectional ability to provide adequate feedback.

Wireless Microphone:
There is a good selection of wireless microphones. These normally consist of a microphone with a wireless interface and a separate receiver that can be placed with the camera. When using a wireless microphone, check that the receiver can be conveniently located with the camera. Some have a hot shoe adapter specifically for use with DSLRs or other cameras that may have a hot shoe flash attachment.
Bluetooth Microphones:
There are very few Bluetooth microphones available .By using a Bluetooth microphone for vlogging, connecting to the smartphone is much easier and there is no need to use the cables that many other forms of microphone constrain. While wired connections are often more reliable, wireless connections are more convenient. . The camera app on smartphones may not be able to accept audio through a Bluetooth connection. For this reason it is necessary to download a camera app that can support this. One may be available with the Bluetooth microphone.
USB Microphones
Another option that is widely used by many video makers and vloggers is a USB microphone. The USB microphone can connect to a computer and provide digitized sound rather than having to use digital conversion in the computer. These microphones tend to be desktop types that can be used while recording from home or at the base location. Some USB microphones can provide excellent quality, but as always, the price generally reflects the overall performance.> Microphone connectors One of the things to consider when buying a microphone for video recording is the connectors. Care needs to be taken when using the small 3.5mm jack connectors . as the connections are different for smartphones and DSLR and other cameras.
DSLR – TRS Connector:
DSLR camera usually has a three way connection or what used to be called a 3.5mm stereo plug with a tip, ring and sleeve connection (hence the name TRS). The tip carries the left channel and the ring carries the right channel. Earth, earth, common sleeve.
Smartphone TRRS Connector:
Smartphones require an extra ring to be able to wear both headphones (left and right) along with a microphone so that people can use the headset for phone calls. These joints with the additional ring are called TRRS, that is, nose, ring, ring, sleeve. The convention for these is that the tip carries the left earpiece, the right center is carried by the near ring. The next ring has the microphone and the sleeve is the common ground. Apple iPhones have microphones on their sleeves, and adjacent rings are common.Connector: Smartphones require an extra ring to be able to wear both headphones (left and right) along with a microphone so that people can use the headset for phone for more visit popularposting.com
