# auditTime

#### signature: `auditTime(duration: number, scheduler?: Scheduler): Observable`

## Ignore for given time then emit most recent value

### Why use `auditTime`

When you are interested in ignoring a source observable for a given amount of time, you can use `auditTime`. A possible use case is to only emit certain events (i.e. mouse clicks) at a maximum rate per second. After the specified duration has passed, the timer is disabled and the most recent source value is emitted on the output Observable, and this process repeats for the next source value.

***

💡 If you want the timer to reset whenever a new event occurs on the source observable, you can use [debounceTime](/learn-rxjs/operators/filtering/debouncetime.md)

***

### Examples

**Example 1: Emit clicks at a rate of at most one click per second**

( [stackBlitz](https://stackblitz.com/edit/typescript-skykxw) )

```js
import { fromEvent } from 'rxjs';
import { auditTime } from 'rxjs/operators';

// Create observable that emits click events
const source = fromEvent(document, 'click');
// Emit clicks at a rate of at most one click per second
const example = source.pipe(auditTime(1000))
// Output (example): '(1s) --- Clicked --- (1s) --- Clicked' 
const subscribe = example.subscribe(val => console.log('Clicked'));
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://www.learnrxjs.io/learn-rxjs/operators/filtering/audittime.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
