Omni

An omni microphone (or omnidirectional microphone) is designed to capture sound equally from all directions, offering a 360-degree pickup pattern. This means it records audio from the front, sides, and rear with equal sensitivity, making it ideal for capturing the natural ambience of a space or for recording multiple sound sources at once. Omni microphones are often used in applications where a more accurate and immersive representation of the environment is desired, such as in field recording, orchestral recording, or capturing room acoustics. While they are great for gathering ambient sound, they can also pick up unwanted background noise if not used carefully in noisy environments.
