With the development of sound reproduction industry came the development of various types of microphones. The type of microphone depends entirely on the use and purpose of the same. Microphones are mainly split into two categories: omni-directional and unidirectional. As the name suggests, omni-directional microphones can pick up sounds equally, to an extent, from all directions. It does not matter from which direction, from the front, rear or sides, the sound is produced, omni-directional microphone will pick it up. Unidirectional microphones only register sound from one direction, hence the prefix uni, meaning one. When it comes to unidirectional microphones, cardioid microphones are perhaps the most popular.
These microphones are named cardioid because of the pattern of their sensitivity, which reproduced on an axis looks like a heart. Cardioid microphones have such range that their best place to pick up sound is when it comes from the front, i.e. when a speaker is speaking directly into the microphone, while the sound from the sides is registered a bit lower, with the sound from behind being picked up in small quantities or not at all. That is why cardioid microphones are best used for live performances, such as concerts, public presentations and in all other situations that require a vocal microphone.
The most known use for these microphones is perhaps in the telephone, as the microphone integrated in the handset only picks up speakers’ voice, eliminating the background noise as much as possible. Cardioid microphones are also used while recording in studio, for vocals and for some certain drum elements.
Whether you want to purchase a cardioid microphone because you want to record your broadcast or podcast, or you maybe want to purchase it for your live shows, it is always hard to find the one that suits you the best. Of course, the main factor when it comes to deciding which cardioid microphone you want to purchase is the budget. The more money you have, better options open up for you.
