What is the specific use of a lavalier microphone?

The lavalier microphone is specifically designed to capture speech from a single individual, making it an ideal choice for interviews, presentations, and performances where the speaker needs to be clearly heard without the microphone being visible or obstructive. Its compact size allows it to be clipped onto clothing near the speaker’s mouth, which helps ensure that the microphone picks up the speaker's voice while minimizing background noise.

By focusing on direct sound from the speaker, the lavalier microphone effectively enhances clarity and intelligibility in audio recordings. This makes it particularly useful in situations where clear dialogue is essential, such as in broadcast journalism, theater, or public speaking engagements.
