# setLocalMicrophoneGain

> Set the local microphone gain as a percentage applied before transmission.

```ts
setLocalMicrophoneGain(value): void
```

Set the local microphone gain as a percentage applied before transmission.

* `0`   = silent
* `100` = unity (no change, default)
* `200` = 2× digital boost (max; expect clipping / noise amplification)

Values are clamped to \[0, 200]. Engages the local audio pipeline on
first use (one-time cost).

Note: this is a **digital** multiplier applied in a Web Audio GainNode
between your mic track and the RTCRtpSender — it does not change the
physical mic's hardware sensitivity. Browsers' autoGainControl can
fight the setting; call [setAutoGainControl](#setautogaincontrol)(false) for
predictable behaviour.

## **Parameters**

**`value`** `number` — required

Gain percentage (0..200; 100 = unity).

## **Returns**

`void`

## **Examples**

call.setLocalMicrophoneGain(value);
```
