Lav Mic (Lavalier)

What is it?

A lavalier — "lav" — is the tiny clip-on microphone worn on the collar, lapel, or shirt: the discreet black dot visible on every TV interviewee's chest. Its defining trait is a fixed, close distance to the mouth: wherever the speaker turns or moves, the mic moves with them, so the voice stays consistent.

Practical example

A presenter walks a factory floor explaining the production line: clipped lav transmitting wirelessly, their voice remains intimate and steady whether they face the camera or point away at machinery — impossible with any camera-mounted mic at that distance. The interview-show version: each guest wears one, giving the mixer a clean, separate channel per person. The creator-economy version exploded recently: cheap wireless lav kits that clip on and transmit straight to a phone turned "walking video with decent sound" from a production job into a consumer purchase.

Key things to know (non-technical)

• Its superpower is consistency in motion — close-mic'd sound that survives walking, turning, and gesturing.
• Its weaknesses are physical: clothing rustle (placement matters), visible on camera (broadcast etiquette tolerates it), and it captures its wearer — room sound and other voices stay distant.
• Wireless is the standard form: transmitter on the person, receiver at the camera/phone — battery and interference management come with the territory.
• One lav per speaker is the multi-person rule; sharing one mic between two people is the audible mistake it sounds like.

In Tupic Live

The wireless lav is the single accessory that most upgrades a Tupic Live mobile broadcast — and the product should treat external mics as first-class: auto-detecting them, showing which mic is live in the audio panel, and gently flagging when a creator is accidentally still on the phone's built-in mic from across the room.
