When choosing a microphone for a computer, it is important to determine the purpose of use. So, studio ones designed for sound recording, little suitable if you just need to chat in voice chats. AND on the contrary, low-level microphones provide too bad audio quality to use them for anything other than conversations.
How to choose a microphone for your computer: what to look for Attention
We recommend that you review the rating of the best microphones for computer according to experts.
When choosing a microphone, you need to pay attention to the following parameters:
Type of connection;
Specifications (sound pressure, directivity, sensitivity level, operating frequency range);
Sound transmission mechanism.
Well, of course, the scope is important. If planned use the microphone exclusively for voice communication conferences and chat rooms, it will be enough to pay attention only to type of connection and design. The remaining parameters are important when it comes to talks about devices designed for sound recording.
Types of microphones for a computer
The design of the microphone largely determines its convenience use. These devices are available in the following configurations:
Headset (earphones with microphone).
The lapel microphone is compact. It is placed directly on clothes and allows you to record sounds, actively moving or even being on the street. However, due to their small size provide not too high-quality sound – “clean”, “deep” Audio can only be achieved in very expensive models.
Desktop microphones can provide very high quality sound, especially the top models. The design of such devices includes a special stand, thanks to which they can be place on the surface. However, they have a drawback – when recording sound, you have to keep your head still, because changing the distance between the mouth and the microphone leads to jumps audio volume.
Headsets lack this flaw, but as well as the eyelets, provide not too high-quality sound due to their compact sizes. However, some microphones of this type equipped with hardware amplifiers and DACs, so the volume, clarity and density of audio are increasing.
In headsets, the microphone and headphones are combined into one device, making them perfect for making phone calls, voice conferences and chats.
Type of connection
The microphone can connect to a computer in one of two ways. ways:
By 3.5 mm audio jack;
The vast majority of microphones involve connecting it is through the “jack”. This provides a number of advantages, among which versatility and the possibility of inclusion in the chain additional devices such as a preamplifier. However, for Converting an analog signal from a microphone to digital audio computer sound card meets and therefore the quality of the finished recordings may be low – even if the device itself is related to the number of “top”.
Microphones that connect to a computer via USB are already have in their design DACs and other devices. Therefore they can provide high-quality sound even on computers in which installed a “weak” audio converter. But it’s worth remembering that in cheap USB microphones are nothing but a sensor and a simple DAC, may not be.
Again, if you only need a microphone for communication, computer sound card, preamplifier, built-in DAC and others parameters can be ignored.
The quality of sound recorded from a microphone is affected by the following parameters:
Working frequency range.
Sound pressure means maximum volume (in dB), which the microphone can record without distortion. The optimal value of this parameter is from 70-75 dB. If a If you plan to record loud sounds, then the sound pressure should to be bigger.
Directivity – a characteristic showing the direction sound absorbing membrane. Microphones are omnidirectional and directed. The first ones pick up sounds from all sides of themselves, the second – only come from a certain point. It is clear that if you need to record speech, it is better to use directional microphones. However, they cost significantly more than non-directional ones. And the result recordings may ultimately seem unpleasant to listening, due to the auditory habits of a person.
The sensitivity level shows the minimum sound volume, which can catch a microphone. It’s very important to reasonably approach fitting this parameter. So, a microphone with a level sensitivity of 10-15 dB, it is easy to catch and record the whisper of a person. However, it will just as well capture the surrounding noise. Therefore not worth buying microphones too high sensitivity.
The operating frequency range shows which part of the sound The frequency spectrum of the microphone is able to catch. Than this parameter wider the better. However, it is worth remembering that the audible sound is in the range of 10-15000 Hz, and human speech in the range 100-10000 Hz.
Sound transmission mechanism
From the point of view of the sound transmission mechanism, microphones are capacitor and dynamic. The first differ most quality recordings and are used in studios – but also very expensive. Why buy a condenser microphone appropriate only if the audio received on it will be subsequently published.
For communication, a cheap dynamic microphone is suitable. The topics more modern models provide very acceptable quality sound.
