# Lavalier (LAV)

Tiny mic, big responsibility

## What it is

A lavalier microphone (often shortened to LAV) is a small, clip-on mic typically attached to a person’s clothing near the chest. It’s commonly used to capture clear, hands-free dialogue.

## Why it's important

LAV mics are discreet, mobile, and offer clear, consistent audio. They are perfect for interviews, presentations, vlogs, or live content where boom mics aren’t practical.

## When/how to use

Use lavaliers in interviews, walk-and-talk scenes, or panel discussions. Always hide cables, check for rustling noise from clothing, and test placement to maintain audio clarity.

## Best Practices

1. **Hide discreetly –** Place lav mics subtly on clothing without causing fabric rustle or visual distraction.
2. **Use wind protection –** Add foam or furry covers to reduce plosives and outdoor noise.
3. **Monitor placement – T**est positioning (chest, collar, tie) for best balance between clarity and natural tone.
