What type of pattern does an omnidirectional microphone have?

An omnidirectional microphone captures sound from all directions equally. This means it is designed to be sensitive to audio input coming from any angle around its central point, allowing it to pick up ambient sounds as well as sound from specific sources. This characteristic makes it particularly useful in situations where sound sources may vary in position, such as a group discussion or a natural environment. The even distribution of sensitivity enables it to effectively record every sound within its vicinity without favoring one direction over another, which is why this type of microphone is commonly used in scenarios like interviews, music recordings, and field recordings.

Other options imply directional characteristics that do not apply to an omnidirectional microphone, highlighting the importance of understanding microphone types and their suitability for specific audio capturing situations.
