Why buy a microphone?

Audio and video production on the Internet has increased impressively in recent times. A research made by Google showed that in Brazil the video consumption has grown 90% in 3 years.

Most of this content is produced by common people, who are not necessarily professionals in the communication area. Some video channels on YouTube, for example, have millions of followers.

A recently published data shows that, in a single day, over 1 billion hours of video are watched on YouTube. For a single person to watch all that, it would take at least 100 thousand years.

To make a video that is good on the networks, it is not enough just to have good images, with high definition. It is also important that the sound is good quality. Bad audio can hinder all the content that has been produced.

Who can stand watching something with a lot of noise or incomprehensible sound? To improve this aspect of videos, one solution is to have an adequate microphone.

Microphones work by capturing the sound and transforming it into an electrical signal, which is then processed and amplified.

Many people may even think that having such equipment is unnecessary. After all, cameras and even mobile phones already have a built-in microphone that is capable of recording sounds.

Only those who think this are making a big mistake. A video with bad audio can scare viewers away and ruin the chances of your content being seen. Investing in a microphone may be worth it.

What is the importance of sound in videos and music?

The sound has a fundamental role in the videos we watch and even more in the music we listen to. If the sound is bad, certainly the viewer will not reach the end of the media, even if the image has quality in the case of videos.

This is because human ears are selective and very sensitive. So, any noise that is not part of the content of your video or music will disturb you, whether it is a squeak, a low volume or some other noise.

Did you know that, according to social scientists, noise is any element that hinders the communication process, that is, that interferes in the transmission of a message between a sender and receiver? Microphones can help eliminate physical noise, such as squealing, buzzing and interference.

To avoid losing the attention of the audience, it is essential to avoid those disturbing sounds. That is why a microphone can bring so many advantages for those who intend to make any type of video.

Cameras and mobile phones have microphones in their own systems, but as they are simple pieces of equipment, many times they are not able to meet all the needs.

With this, we realize that a microphone can be very advantageous because it reproduces with more quality the audio captured and can make your productions more professional.

What are the different types of capture of a microphone?

Not all microphones are equal. They have very important differences that will make a difference when you are using them.

One of the characteristics that differentiate one microphone from another is the way in which it picks up the sounds that are around it. In other words, it is in which direction the product can or cannot record audio.

A microphone, in general, can be unidirectional, bidirectional or omnidirectional. Let us explain each of them

  • Unidirectional microphone: As the name says, it is capable of recording the sound that comes from only one direction, in general, from the front. It does not record ambient sound. They can be further subdivided into cardioids, supercardioids and hypercardioids. Each of them has a higher level of sensitivity to the sound.
  • Bidirectional microphone: they are able to pick up sounds coming from the front and also from the back, leaving lateral sounds out. It is especially useful when you want to record two people talking to each other.
  • Omnidirectional microphone: These are capable of capturing audio in 360 degrees. All surrounding sounds can be recorded. It is mainly used in concerts and artistic performances.
Did you know that the microphone was created on March 4, 1877?

The German naturalised American, Emilie Berninder was responsible. Alexander Graham Bell was impressed by the invention and bought the patent.

Graham Bell then adapted the equipment and made it functional. The microphone eventually served as the basis for the invention of the telephone, radio and TV.

What is the pickup sensitivity of the microphone?

Besides the type of pickup, microphones have different pickup sensitivities. Some are "harder", others are "softer". They can be divided into dynamic or condenser.

The dynamic type is considered hard and therefore less sensitive. With it, it is possible to capture very low or very high sounds. In general, they capture the closest audio and exclude those that are further away.

This type is also more resistant to falls and is quite versatile. A disadvantage is the lower level of detail of the audio recorded.

The condenser type shows more details of the sound and is considered soft. The pick-up is therefore considered more sensitive. They are more expensive and not as resistant as the other type. Compare the two models:

Dynamic Microphone Condenser Microphone
Resistance More impact resistant Less impact resistant, more fragile
Sound detail More impact resistant Less impact resistant
Advantage More adaptable to sound variations Cleaner audio
Cost More expensive prices Lower prices
Indication Aimed at outdoor and indoor recordings Aimed at indoor recordings

Buying Criteria: Factors to Compare the Different Microphone Models

Have you decided you need a microphone? Then it's time to go through all the details before making your purchase. That way, you get the best value for your money.

When choosing which microphone to take home, consider the following points

  • Use
  • Compatibility with other equipments
  • Frequency
  • Mobility

We are going to talk a little bit about each one of them in the sequence.

Use

Each microphone has a different characteristic. As we said before, the type of pick-up and also the sensitivity vary from model to model. This way, for you to buy the product that will suit your needs, it is fundamental to be very clear what you intend to do with the microphone.

The ideal microphone will depend on what the main use will be. For each necessity, a microphone is the most indicated.

In case you are going to make a recording in external environment or in occasions where there is a lot of noise, a lapel microphone can be the ideal one.

As this type of microphone is closer to the mouth of who is speaking, the device captures mainly the voice and little of the environment sound. This type of microphone may be wired or wireless. Lavalier microphones are small and discreet.

A traditional directional microphone, other than a lavalier, picks up sound only in the direction it is pointed. It is used in many types of recording, both with a stand and with someone handling it.

This type of microphone can be used for both indoor and outdoor recording. In both occasions, close and distant sounds can be captured.

Condenser microphones, finally, are aimed for indoor use in the most studio-like environments possible. This is because they are very sensitive and have high pick-up capability.

They also require the use of a type of power supply known as Phantom Power. This is a sound box or similar equipment that powers the microphone with an appropriate voltage.

In such cases, the microphone should be connected before the power supply is switched on, to prevent any device from burning out.

Compatibility with other equipment

Nowadays, anyone can be a video producer. Cameras have become cheaper and smartphones have more and more features. Those who want to improve the audio quality of their videos with a microphone should pay attention to whether the chosen model is compatible with their other equipment.

Not all of them, for example, are able to connect a telephone. Some only have their own microphone connection, such as p2 or p10. One way to avoid this problem is to count on the help of an adapter for this type of port.

Another alternative is to opt for a microphone with USB input. This is a good solution especially for those who record videos in front of a computer. This is the case of many vloggers and youtubers.

Frequency

In this case, once again, it is essential that you know how you will use the microphone. Evaluate if the frequency that the equipment captures is recommended. This is because a microphone does not need to be able to capture all the frequencies heard by the human being.

Whoever is looking for a product that captures the sounds emitted by musical instruments, for example, must research at what frequency the sound is emitted. As musical instruments have already defined frequencies, the microphone used for recording must be able to pick up these sound frequencies.

The drumhead has no high frequencies, so we have to use a microphone that has good bass response, for example.

Mobility

Especially speaking of traditional microphones, those used on stage, the microphones may be wired, and thus be connected directly to the device such as a speaker or table, or even wireless.

The wireless microphone has a battery, but offers greater freedom of movement. It transforms the captured sound into an electrical signal. The wired microphone, on the other hand, offers greater sound control. Not to mention that they are usually the cheapest versions.

Both have advantages and disadvantages, put them on the tip of the pencil and evaluate them before choosing yours.
