What type of microphone pattern allows for recording multiple voices with one microphone?

The omnidirectional microphone pattern is specifically designed to capture sound equally from all directions, making it ideal for recording multiple voices with a single microphone. This feature allows the microphone to pick up audio sources from the front, sides, and rear without discrimination. When several speakers are present, such as in a group discussion or an interview setting, the omnidirectional pattern ensures that each participant's voice can be captured clearly, providing a more natural and comprehensive recording.

In contrast, other microphone patterns like cardioid, unidirectional, and hypercardioid are more focused on sound coming from a specific direction, which may limit their effectiveness in scenarios with multiple sound sources surrounding the microphone.
