An omnidirectional microphone is a type of microphone that captures sound equally from all directions. This design allows it to pick up audio from the surrounding environment, making it ideal for recording group conversations, ambient sounds, or live performances. These microphones are commonly used in various applications, including podcasting, film production, and musical performances. Their ability to capture sound from multiple angles provides a natural and immersive audio experience, making them a popular choice for many audio recording scenarios.
