A Guide to Buy a USB Microphone, Know the Following Points Before Starting!

The USB microphone refers to a microphone that transmits audio through a USB cable. This type of microphone usually integrates the mic and the sound card, and includes a built-in mic preamp, AD module. Compared with the professional XLR microphone + sound card combination, most of the similar products on the market are lacking in professional quality such as sound quality.
1. What Is A USB Microphone
The USB microphone refers to a microphone that transmits audio through a USB cable. This type of microphone usually integrates the mic and the sound card, and includes a built-in mic preamp, AD module. Compared with the professional XLR microphone + sound card combination, most of the similar products on the market are lacking in professional quality such as sound quality.
However, the advantages of USB microphones are also very obvious, mainly reflected in the following aspects:
 
·Wide Range of Applications
The majority of USB microphones are equipped with a variety of pickup patterns, which can be adjusted in accordance with recording needs.

· Built-in Monitoring Function
Some USB microphones will have monitoring function, and you can adjust the recording status in real time according to the sound feedback to achieve the perfect recording effect.
 
·Multiple Functions
Some full-featured USB microphones will be equipped with gain, headphone volume, mute control and other functions, which is easy to use even for the first time.
 
·Cost-Effective
 
Compared with the professional microphone + sound card combination, the USB microphone is more cost-effective, and users do not need to master the knowledge of audio. It is the best choice for recording equipment. In addition, the USB microphone can also be connected to a mobile device through the including cables, which is equivalent to an external recording device to the mobile phone.
If you don't have much professional needs for audio recording, then a USB microphone will be your first choice, suitable for amateur dubbing, indoor recording, online classes, online meetings, game live streaming and other usage scenarios.

2. Instructions for Purchasing a USB mic
①. Budget
Choose the most suitable USB microphone for you within the affordable price. Setting a budget can help us spend rationally and prevent impulse purchases.
There are many similar products on the market. According to your own budget, you can eliminate a large number of unsuitable products and narrow your choice to improve shopping efficiency and save time.
 
②. Brand
The products produced by professional counterpart brands will be more reassuring in terms of quality and pre-sale and after-sale services.
 
③. Microphone Type
At present, the microphones are mainly divided into two types: dynamic microphones and condenser microphones, each with their own advantages and disadvantages.
The dynamic microphone has the characteristics of low sensitivity, good noise reduction and durability;
Condenser microphones have higher pickup sensitivity which can capture more sound details, but they are also more delicate and less durable than dynamic microphones.

 
 
④. Core Parameters
·Polar Pattern
The directivity parameter refers to the pickup range of the microphone. At present, the polar pattern of USB microphones mainly includes the following:
Omnidirectional: Pick up sound equally from all directions.
Cardioid: Pick up the sound in front of the microphone, and minimize to the sound from the sides and back.
Supercardioid: Same as cardioid, but also pick up some of the sound at the back of the mic.
It should be noted that since the supercardioid pattern will pick up part of the sound behind, do not let the noise source appear behind the microphone when using it.
 
·Frequency Response
The frequency range of the sound that the human can hear is 20Hz~20kHz. With this range as a criterion, the larger the range, the more realistic and specific the sound is picked up, but not necessarily clear.
There will be a low-cut function for some mics, which reduces low-frequency noise and makes the sound clearer.
 
·Signal to Noise Ratio
The higher the ratio of sound signal to noise, the better.
 
·SensitivityWhether it is in mv/pa or BV/pa, the higher the value, the better.
