What does the term 'omnidirectional' refer to in microphones?

The term 'omnidirectional' in microphones specifically refers to their ability to capture sound equally from multiple directions. This means that the microphone is designed to pick up audio signals coming from all around it, rather than focusing on sound from a single source or direction. This characteristic makes omnidirectional microphones particularly useful in situations where you want to record ambient noise or capture voices from various directions, such as in group interviews or while recording music in a natural setting. Their design allows for a more natural and balanced sound pickup, making them ideal for applications where sound sources are not fixed or are spread out in multiple directions.
