Microphones on your smartphones are often not of the best quality. For some reason, many manufacturers bypass such an important point.
However, without a normal, high-quality microphone, it is simply impossible to record a good video or interview. Constant noises, external sounds can just ruin the whole shooting of the video. Learn more at micspeech.
Why do you need a microphone for a smartphone
Modern smartphones in rare cases have a high-quality microphone. Most often the devices are equipped with a very good camera, sometimes even with semi-professionals. But they are simply lost in the background of the fact that the recording is heavily subsided.
To record high-quality video, save the moment, and not constantly adjust the microphone and sound on your phone, you just need a high-quality external microphone, which you can now buy as an additional one.
Such devices will help people like:
- students (because it is often necessary to record a lecture);
These people just can’t do without devices that produce high-quality sound. For example, journalists may need to take an interview at any time. He will not always carry a high-quality camera or a large voice recorder. A small and high-quality external microphone is what he needs.
Musicians can record their creativity right on the phone. You do not need to go to the recording studio for this purpose. You can always use your microphone. This saves money.
In General, an external microphone is a very useful invention that will help many users forget about the bad sound on the video. A high-quality device will help completely suppress any noise, sounds, and other interference that will not need to be turned later in the settings.
Varieties of external microphones
External microphones are also divided into several large categories, namely 3:
- stereo (these are more suitable for creative individuals, including musicians).
The buttonhole gadgets are great for mounting on any clothes. They differ in small size. Lavaliers are used to record a person’s voice. So this kind of device is perfect for bloggers and journalists who constantly need to regulate such an object as excellent voice quality.
Typically, such microphones have one major drawback – non-directionality. That is, extraneous noise is perfectly audible when recording from such a device. Also, the buttonholes are not suitable for recording music as their frequency range is limited.
The second type is a gun mic. They are called that because they are directed in one direction. That is, they cover the minus of the buttonhole microphones and do not create noise in the background. Recording from these microphones is performed ahead of the user.
Therefore, it is necessary to constantly monitor the process so that the voice falls into the microphone. If you hold the sound directly away from the source, then you can detect that the voice is suppressed, meaning that the device has removed extraneous noise.
Guns are not suitable for recording songs, so they are aimed. You can’t create a full sound with this device. But for those who want to achieve a clear voice when recording an interview or video, this option is the best.
The last type is the stereo. Stereo devices are ideal for musicians. This type of microphone not only captures the sound throughout the room but also beautifully beats it, makes it three-dimensional. Many models may differ in price, but this is not the case. You can buy different price categories, but the sound quality may suffer.
Microphones can also be wired or wireless, but this classification does not stand out as the main one. The difference is the connection method. Wireless devices are synced with your smartphone using a simple Internet connection or Bluetooth, while wired devices need to be connected via special wires.
How to choose an external microphone for your smartphone
Choosing a microphone is one of the most important things to consider if you want to record high-quality audio on your device. In fact, there are several criteria that are the basis of choice:
- wire length;
- device compatibility;
- cardioid regulation
The length of the wire is how far the user will be able to move away from the smartphone, and the sound will remain good. A wire that is too long or too small is equally inconvenient. It’s worth finding a middle ground.
The goals are what the device is used for. You need to determine the type based on the purpose of the device.
The dimensions of the microphone
As for the size of the microphone, there is a rule – the larger the microphone, the higher the quality. Video bloggers are advised to purchase fairly small devices, but musicians should pay attention to larger models.
The microphone must come with additional equipment in the form of an adapter or windshield.
Frequencies are an important point. If the microphone has a range of more than 20,000 Hz, then this device is not of the best quality. If a microphone is purchased for interviewing or recording audio for a blog, such a wide frequency range will not be an advantage.
The equipment will record not only the sound of the voice but also the noise in the next room. A microphone with a range of 60-15000 Hz will allow you to record a conversation even more efficiently.
For musicians, the bandwidth must be as wide as possible. Otherwise, you will not be able to reflect the authentic sound of the instruments. For example, the frequency range of a piano starts from 27 Hz. If you write a piano on a microphone of 60-15000 Hz, the sound will be too mechanical.
The choice of the pattern
The last point is cardioid. Directivity is the sensitivity of the microphone to sound depending on the direction or angle from which the sound is coming.
Setting this indicator means that the user can fully adjust what the device will hear. This can only be the voice itself, and you can also configure the ability to capture the entire room. This is a great way to regulate the recording process.
