Which term refers to a microphone pattern that captures sound from all directions around the microphone?

• A. Bidirectional Microphone
• B. Omnidirectional Microphone
• C. Unidirectional Microphone
• D. Lavalier Microphone

Answer: (B)

An omnidirectional microphone pattern is designed to pick up sound from all directions around the microphone, giving 360-degree coverage with roughly equal sensitivity in all directions. This makes it ideal for capturing ambient room sound or when multiple sources surround the mic. In contrast, a bidirectional pattern records from the front and back while reducing sound from the sides; a unidirectional (cardioid) pattern mainly captures from the front with strong attenuation from the rear and sides; and a lavalier is a type of microphone worn on the body and can use various patterns, but it’s not itself a pattern term.
