When buying a microphone you should first ask yourself, for what purpose do I need it? The answer to this question is already taking you half the way, although the range of alternatives is huge.

The second question to ask is, what polar pattern do you need - describes the way the audio is received. Which polar pattern meets my necessities best? There are three basic patterns - omnidirectional, bi-directional or cardioid. Cardiod is again divided in supercardioid and hypercardioid:

  • Omnidirectional: captures the sound from all directions. It is normally used in situations you can't control well, like a company conference or a person speaking while moving around. 
  • Bi-directional: captures the sounds well from the front or behind, but not from the side. Therefore it is perfect for podcasts or interviews on the radio. 
  • Cardioid: captures the sound from the front and less from behind. It is perfect for recordings of documentations, marriages or events, however they also capture background sounds in an uncontrolled environment.
    • Supercardioid: this characteristic is used to not only capture the sound from the front, but also from the back, but with focus to the front. Ideal for recording live or scripted content or for independent filmmakers. The microphone enables the user to isolate sounds. It is mostly used on top of cameras, but you will need to reduce your operating sounds to a minimum. 
    • Hypercardioid: the hypercardioid characteristic is similar to the omnidirectional and captures sounds from all directions, which is ideal to isolate sounds. Normally you'll find this type in shotgun microphones. Ideal to record instruments or documentaries. The difference between the supercardioid and hypercardioid lies within the area of sound captured from behind or lateral.


Types of microphones and their functionalities

After deciding which polar pattern is suitable for your purpose, you'll need to decide on the microphone model. The market offers a huge variety of microphones. With so many to choose from it is difficult to know which microphone is meant for what purpose. We have summarized the common models on the market.


USB Microphone

The USB microphone is meant for PCs and is used for podcasts or other voice recordings on the computer. The plug-and-play technology simplifies the connection and configuration. The microphone is automatically detected and no further driver needs to be installed.


Condenser microphone

A condenser microphone is good for recordings with more depth, details and intricacies, but the surroundings need to be quiet. It is ideal for recordings in a studio or of acoustic instruments.


Dynamic microphone

Dynamic microphones are used if you want to avoid undesired background noises - ideal for live shows or recording in everyday life.


Directional microphone

A directional microphone is a long tubular microphone which focuses on only one source of sound. The microphone is able to capture the maximum of a particular sound as well as possible without any background sound. They are ideal for recordings of specific noise sources, like actors on a stage or a fishing rod in nature for example.


Lavalier microphone

The lavalier microphone is a small and discreet microphone that can be attached to the shirt of a speaker for example. Mostly they are used for television broadcasts and interviews. The huge advantage is that you can place it close to the sound source. The lavalier microphone is also used in filming to capture the actor's voice clearly.


Smartphone microphone

The smartphone microphone is similar to the lavalier. It captures the voice in high quality when making a call or recording a video.


Wireless microphone

A wireless microphone converts an acoustic signal into a radio signal and sends it to the receiver. These microphones enable a large range of movement with high sound quality. They are mostly used in concerts and on TV shows.


Bluetooth microphone

Without a cable, the transmission goes via bluetooth, however sound quality isn't so good, due to the smaller bandwidth of bluetooth. It is, for example, an alternative in transmission of spoken words through the phone.



The price range for microphones depends on their category. An amateur microphone is available for around 50 €. Better options costs an average of 170 €. But if you want a professional microphone, you'll need to dig deeper into your pocket. The prices have almost no limit. There are microphones that go for 5 mil. €.
