An omnidirectional microphone is a type of microphone that captures sound equally from all directions. Its main function is to provide a full, natural sound that is true to the environment in which it is recorded. Technological features include a simple design with a single diaphragm and capsule that is sensitive to sound pressure from any direction, ensuring there are no dead spots. This microphone is typically used in situations that require a wide pickup pattern, such as in conferences, interviews, and field recordings. It eliminates the need for precise positioning and allows for more flexibility during recording sessions.
