Microphones are considered very useful devices. However, you should know that microphones have different types. Microphones vary in technology and the direction that they use. Because of these differences, you will need, what properties of the microphone you need to know before you decide to purchase.
When selecting a microphone, there are some things you must consider. These include:
Impedance - in microphones, low impedance microphone is much better than aMicrophone with a high impedance. However, it is pretty obvious that high-impedance microphones are relatively cheaper. The major disadvantage of high-impedance microphones is that they do not perform well in long-distance cables. For this reason, low-impedance microphones are preferred.
Frequency Response - In choosing a microphone, you must ensure that the microphone is capable of frequency response for your needs. Frequency actually refers to the way the microphoneResponse to different frequencies. Some frequencies may be exaggerated, while reducing some of them. Condenser microphones have a flatter spectrum compared to dynamic microphones. So if you want to make a precise sound, you should consider using a capacitor microphone.
Directionality - Since microphones differ in their directional characteristics, you must decide which you choose meets your needs best. Note that preferred a less directional microphone when the microphone is to be usedin a position that is close to the sound source. The directionality determines the microphone's sensitivity to sound from different directions. There are some microphones that pick up sounds equally from all directions, while there are some that pick up sounds from one direction or from different combination of directions.
Handling Noise - Keep in mind that the diaphragm of the microphone works by translating vibrations from sound waves into electrical signals. The diaphragm of a Microphone can not distinguish the difference between a sound wave is desirable, vibrations and other vibrations. Therefore, any vibration is a part of the produced audio signal.
So, if you must use a microphone and a lot are exposed to unwanted vibrations, you should use a microphone that has a capability of handling noise. There are high-end microphones, which filters unwanted vibration and generate a high quality audio. These types of microphones, a foam padding orSuspension to isolate the membrane.
To sum up, the sound quality is subjective. If you have a microphone that you want a good sound quality, you can record the same sounds with different microphones and then select the microphone that the sound that you want made.
