> Returns the current audio level for the local participant.

`getLocalAudioLevel()`

<Badge color="green">{"✓"} Prebuilt</Badge> <Badge color="green">{"✓"} Custom</Badge>

<Warning>
  You must call [`startLocalAudioLevelObserver()`](/reference/daily-js/instance-methods/start-local-audio-level-observer) before calling this method — otherwise it returns `0`.
</Warning>

## Return value

Returns a `number` between `0.0` (silence) and `1.0` (maximum volume). The value is updated on the interval set when `startLocalAudioLevelObserver()` was called (default: 100ms).

## Example

```javascript theme={null}
await call.startLocalAudioLevelObserver(100);

// Poll or call on a timer to get the current level
const level = call.getLocalAudioLevel();
console.log('Local audio level:', level); // e.g. 0.625
```
