An omnidirectional microphone is a type of microphone that captures sound equally from all directions. This design allows it to pick up audio from multiple sources without needing to be pointed directly at a specific sound source. It is commonly used in situations like interviews, conferences, and recording environments where ambient sound is important. These microphones are particularly useful in settings where the speaker may move around or when multiple speakers are present. Their ability to capture a natural sound field makes them popular in music recording, podcasting, and film production, providing a more immersive listening experience.
