Types of Microphone

In doing my past projects I have hardly ever managed to get the sound adequate as I often think of it as much more of a last minute thing in the pre-production steps. I discovered a video blog called Types of Microphone, on youtube created by a video marketing agency, Lambda Films. It covers the different types of microphones that may be used to pick up sound. Like, bi-directional, cardioid, shotgun and Lavalier microphones. It is crucial to select the right microphone so that you can make the best quality audio, the technical side of sound is something which should be properly thought through, looking at the pros and cons of the different types of microphones, depending on what exactly is being shot.

In pre and post-production steps of a venture generally what is thought of as the most vital aspect is the visual imagery. Focusing on the brainstorming, scripting and storyboarding, getting caught up with this particular aspect of the pre-production and forgetting at times about the preparation and testing that would be needed for audio. Audio is just as crucial as the visual side of things. It would be no use to have incredible visuals and narrative, but then incoherent audio. This would make the whole venture useless, and require it all to be reshot again with higher quality sound, wasting time and money.

I will explain the four types of microphones mentioned in the video blog, beginning with the shotgun microphone, which happens to be the most directional, this means it picks up the sound extremely well at whatever it is directed at, however is far less sensitive to the side and the back of the microphone. This may be seen as both a positive and negative, since it means that they do not pick up surrounding audio, concentrating only on whatever it is pointing at. That makes them good for use on boom poles, which means that they are most commonly used on television and movie sets. Similar to shotgun microphones, cardioid ones pick up audio only from the front nevertheless it is significantly less sensitive when compared with the shotguns microphones, instead which makes them good for live vocals. And as opposed to shotgun microphones, bi-directional models pick up audio equally from both the back and the front. Finally, additionally discuss the Lavalier microphone, this one is the most portable out of the four discussed in the video, as it clips onto the subject, making it great for interviews. They are discrete as they can be clipped onto clothing and concealed, nevertheless they still pick up speech very clearly. They can come either as wireless or wired, both having advantages of their own. Wireless meaning that it makes for even more portability, cable free, while wired microphones mean it is not necessary to mess about and worry about audio channels or batteries. Other key situations to use the Lavalier microphone could be theatre and for public speaking situations.

This blog post has given a brief introduction into the different types of microphones, yet this still demonstrates the worth of planning the audio and ensuring the correct microphone is used to complete the project.
