The onstatechange property of the BaseAudioContext interface defines an event handler function to be called when the statechange event fires: this occurs when the audio context's state changes.
Syntax
baseAudioContext.onstatechange = function() { ... };
Example
The following snippet is taken from our AudioContext states demo (see it running live.) The onstatechange hander is used to log the current state to the console every time it changes.
audioCtx.onstatechange = function() {
console.log(audioCtx.state);
}
