Answer:
An omnidirectional microphone picks sound from all directions. This microphone has 360 degree output.
Explanation:
- The speaker can speak from any side or any direction. While the unidirectional microphones records sound from only the direction that the speaker is, omnidirectional microphone records sound from all directions.
- Picking sound from all directions does not always make the  omnidirectional microphone the better one as some times, it may not be required or creates more disturbance.
- Based on the application of the situation, one can decide whether omnidirectional or unidirectional microphone should be used.
