What's the difference between the types of directional microphones? The primary difference between omnidirectional microphones and unidirectional microphones is that omnidirectional microphones pick up sound 360 degrees around, while unidirectional microphones must be pointed at the source of the sound in order to pick it up. 

 

 

If the voice or sound is to the side of the microphone, the microphone will not pick the sound up clearly. If behind the microphone, the sound may not register at all, no matter how close it is to the actual microphone. Despite the common image of a microphone with a rounded end, unidirectional microphones do not usually come in that distinctive shape. 

 

 

Unidirectional microphones are usually used where too much background noise would be picked up by an omnidirectional unit. For example, the most popular style of karaoke microphone is the unidirectional microphone. Unidirectional microphones are also used by musicians seeking to record the sound of one instrument.

However, if a band has background singers or many band members playing at once, an omnidirectional microphone will be best for picking up these varying sounds.

There are three main types of unidirectional microphones, including cardioid, hypercardioid and supercardioid. Cardioid microphones are most sensitive straight on, and cannot capture sounds at the back of the microphone.

When you’re looking for a unidirectional microphone, consider the ambient noise filters. While unidirectional microphones do have an advantage over omnidirectional microphones in this respect, noise filters can help you achieve the best sound possible.

The sensitivity of the microphone is another quality to check out. Make sure the microphone will be sensitive enough to pick up quiet sounds if this is important for your purposes.

Depending on the application for which it will be used, you may want to look into purchasing a lightweight microphone. You’ll also need to decide between one with a cable and a wireless version. When looking at wireless microphones, make sure that the range will be long enough for your purposes. 

The cost of aunidirectional microphone varies widely. Budget systems are available that are good for karaoke or other amateur uses. As with most electronics, these budget systems are a bit lower quality than high-end systems. However, they will still produce good sound for most purposes. Of course, there are high-end microphones available for professional use.
