What is the main purpose of a lavalier microphone?

The main purpose of a lavalier microphone is to attach directly to a speaker, allowing for hands-free operation while capturing audio. This type of microphone is typically small and can be clipped to a person's clothing, which helps it to gather the speaker's voice clearly without the need for a handheld device. This setup is particularly beneficial in interviews, presentations, and performances where the speaker may need to move freely or use both hands, ensuring that the microphone remains in a consistent position relative to the sound source for optimal audio quality.

In contrast, a lavalier microphone is not primarily designed to enhance ambient sound, provide a handheld option, or reduce background noise. While some lavalier microphones may possess features that help isolate the speaker’s voice from background noise, their primary function remains focused on creating a direct audio link with the speaker. This allows for clarity and focus on the spoken word, which is essential in many audio-visual contexts.
