/**
* Represents the speaker playback audio destination, which only works in browser.
* Note: the SDK will try to use <a href="https://www.w3.org/TR/media-source/">Media Source Extensions</a> to play audio.
* Mp3 format has better supports on Microsoft Edge, Chrome and Safari (desktop), so, it's better to specify mp3 format for playback.
* @class SpeakerAudioDestination
* Updated in version 1.17.0
