AudioPlaybackStats: toJSON() method
The toJSON() method of the AudioPlaybackStats interface is a serializer; it returns a JSON representation of the AudioPlaybackStats object.
Syntax
js
toJSON()
Parameters
None.
Return value
A JSON object that is the serialization of the AudioPlaybackStats object.
Examples
Using the toJSON method
In this example, calling stats.toJSON() returns a JSON representation of the AudioPlaybackStats object.
js
const audioCtx = new AudioContext();
const stats = audioCtx.playbackStats;
// ...
// Log current total duration
console.log(stats.toJSON());
This would log a JSON object like so:
json
{
"underrunDuration": 0,
"underrunEvents": 0,
"totalDuration": 68.252138,
"averageLatency": 0.01863,
"minimumLatency": 0,
"maximumLatency": 0.018654
}
To get a JSON string, you can use JSON.stringify(stats) directly; it will call toJSON() automatically.
