I started the test, the melody is playing, but I haven’t found a way to stop it.

I tried:

```auto
  /** Stops local audio capture */
  stop(): Promise<void | Error>;

  /** Mutes mic if audio was started, and mic is not already muted */
  mute(): Promise<void | Error>;

```

And also run the second test with the id of a non-existent device, but i get console message

> A tester is running,please stop it first

I was also looking for elements with the “audio” or “video” tag to stop them =)

But none of this helps…

Zoom Web Video SDK 1.4

Hey @efron.vit

Thanks for your feedback.

The `localAudioTrack.testSpeaker()` method returns a controller, using it to `stop` or `destroy` the tester.  
Here is the reference: [LocalAudioTrack | Zoom Video SDK for Web - 1.4.0](https://marketplacefront.zoom.us/sdk/custom/web/interfaces/localaudiotrack.html#testspeaker)

If you are familiar with react, our react sample code gives a demo of how to use the tester. [videosdk-web-sample/preview.tsx at master · zoom/videosdk-web-sample · GitHub](https://github.com/zoom/videosdk-web-sample/blob/master/react-demo/src/feature/preview/preview.tsx#L207)

Thanks  
Vic

Thank you very much for the quick response! This is what is needed. I program in Vue JS =)

@vic.yang, can we get the value of the current volume of this track for visualization?

Hey @efron.vit

The [TestSpeakerOption](https://marketplacefront.zoom.us/sdk/custom/web/interfaces/testspeakeroption.html) allows you to set the `onAnalyseFrequency` callback, the callback will be invoked per 20ms with the `averageFrequency` payload, it’s another measurement of the sound. It can be used to visualize the sound.

In our [react sample app](https://github.com/zoom/videosdk-web-sample/blob/master/react-demo/src/feature/preview/preview.tsx#L214), we use it as the percent value of the progress bar.

P.S.  
[Some visualization examples and APIs in MDN.](https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API/Visualizations_with_Web_Audio_API)

Thanks  
Vic
