omnidirectional and unidirectional microphones

  1. 1. • Omni directional microphones pick up sounds from virtually and direction. This type of microphone is useful when it needs to pick up sounds from the surroundings, and isn't ideal to move the microphone along with the sound.
  2. 2. Advantages • Omni directional microphones can be very easy to set up and use, even by inexperienced people who may not have used one before. Due to this, it is very easy to manage for someone with no experience, and reduces further costs. • Omni directional microphones are cheap to buy, yet produce high quality audio
  3. 3. Disadvantages • Could produce unclear sound and of poor quality due to neighbouring sounds. • The inability to discriminate between wanted and unwanted sounds means that unwanted noise can be picked up and amplified.
  4. 4. • Picks up sound predominantly from one direction. This includes cardioid and hypercardioid microphones Cardioid • Sound is picked up mostly from the front, but to a lesser extent the sides as well. • The cardioid is a very versatile microphone, ideal for general use. Handheld mikes are usually cardioid.
  5. 5. • Hypercardioid • An exaggerated version of the cardioid pattern. It is very directional and eliminates most sound from the sides and rear • Uses: Isolating the sound from a subject or direction when there is a lot of ambient noise; Picking up sound from a subject at a distance. Disadvantages • By removing all the ambient noise, unidirectional sound can sometimes be a little unnatural. It may help to add a discreet audio bed from another mike (i.e. constant background noise at a low level). • You need to be careful to keep the sound consistent. If the mike doesn't stay pointed at the subject you will lose the audio.
