How to choose a good microphone

Author:admin   AddTime:2021-03-22

Whether it is professional recording or family karaoke, it lacks the help of a microphone. Especially for novices, a microphone with outstanding performance can bring better sound quality tones, so how to choose a microphone?

Generally, when choosing a microphone, you should consider indicators such as microphone type, sound directivity, use occasion, and transmission mode.

1. Classified by price
1. Taobao goods
Mainly manifested in the low price, generally less than 100 yuan, not very practical.

2. Special microphone for mobile phone
Many karaoke platforms have their own products, and karaoke platforms have internet celebrities, so most of the customized models will use internet celebrities as promotional selling points, and the price is almost between 200 and 600 yuan.
The traditional manufacturers Philips, Lenovo, etc. also have individual platform customization models and their own brand models, but the appearance may not be as brilliant and eye-catching as the K song platform products, suitable for home use.

3. Professional level
It is usually used by those who need professional recording, and need to be equipped with professional sound card, recording studio, etc. And we found that the professional-biased brands also have products for the mobile K song platform, but the interface is also more professional and suitable for more professional anchors.

Second, select according to performance
1. Tuning effect
There are microphones on the market with their own tuning effects and built-in audio chip processing, but the price is at least 1,000 yuan.
I have seen a video of recorded music before, and the difference between the music output by the tuner and the singer's singing is still quite different.

2. Real-time ear return
"Real-time ear return", this function is simply that when we sing with our mobile phone (headphone mode), in addition to the sound of the accompaniment, the earphone can also show our own voice in real time.
The ear return function can not only transmit the background music directly to our ears, but more importantly, it will output the final result of mixing the background music with our own singing voice, which is the sound of the final recording.
At present, most microphones on the market already support the real-time ear return function. It is best to choose products with this function when purchasing.

3. Pickup directivity
Microphone directivity is a description of the microphone's pattern of sound inspiration from all directions in space, and is an important attribute of the microphone.
There are omnidirectional, single-directional, cardioid, and bidirectional. The microphones commonly used in karaoke are generally cardioid.
Cardioid direction: The characteristics of the microphone's pickup are like cardioid, the sensitivity of the front of the microphone is the best, and the degree of reproduction is the highest (the position of the apex of the heart). The back of the microphone has the worst sensitivity and the lowest degree of reproduction (the tail of the heart).

4. Condenser microphones are preferred
For a slightly more professional recording, it is best to choose a condenser microphone. The condenser microphone picks up clearly and has high sensitivity, but the disadvantage is that the environment is noisy and can easily cause howling. The dynamic microphone is not easy to cause howling and is suitable for noisy environments.

5. Platform compatibility
The first choice of mobile phone microphone must be compatible with Apple and Android systems. Currently, the more common microphone products on the market have very good cross-platform compatibility.
In addition, you must also look at the interface compatibility of the microphone. If you are using a Xiaomi mobile phone, you need to pay attention: some of the current mid-priced microphones will have a sound noise that is compatible with Xiaomi. It is recommended to choose TLIFE or a more expensive professional. Class microphone.
iPhone users need to choose an external device with a lightning interface. There are very few microphones that have been officially certified by Apple to adapt to the lightning interface. TLIFE is currently the first one, and it can be used without certification, but there may be a risk that it cannot be used in the later iPhone system upgrade.

6. Noise canceling function
Although the mobile phone comes with part of the noise cancellation function, but the built-in noise cancellation function is limited, the noise cancellation function of the microphone is particularly important, and you should pay attention to it when choosing.

7. Reverberation or real sound?
Most mobile phone microphones will support reverberation mode, including KTV, concert hall, and recording studio. And it will also support K song "listen wet and record dry", "listen wet and record wet" functions, and also support treble assist (when singing high notes), mid-range (songs with little ups and downs), down-range (for low voice), etc. Mode to help improve the sound.
The so-called wet recording is dry, when you sing, you hear the "wet" sound, which means that it brings in the reverberation effect. The recorded "dry" sound is an unprocessed sound effect. You will only use it if you need to tune it yourself later.
To listen to wet recording is to add reverberation effect when hearing and recording. This is used when you do not need to post-process by yourself. Generally, this mode is recommended for karaoke platforms.

Brief summary
If you have a very good radio environment and need to record high-quality vocal audio, then choose a condenser microphone. If you are a beginner and have a poor radio environment (such as outdoor interviews, concerts) and loud noises, choosing a dynamic microphone with low sensitivity would not be more appropriate.
The characteristics of condenser microphones: high sensitivity, fast instantaneous response, extremely wide frequency response, intolerance, fear of falling and fear of tides.
The characteristics of dynamic microphones: low sensitivity, slow instantaneous response, narrow frequency response, drop resistance and build resistance.
