AudioWorkletNode: processorerror event
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The processorerror
event fires when the underlying AudioWorkletProcessor
behind the node throws an exception in its constructor, the process
method, or any user-defined class method.
Once an exception is thrown, the processor (and thus the node) will output silence throughout its lifetime.
Syntax
Use the event name in methods like addEventListener()
, or set an event handler property.
addEventListener("processorerror", (event) => { })
onprocessorerror = (event) => { }
Event type
A generic Event
.
Examples
To be informed when the processor throws an exception, you can add a handler to your AudioWorkletNode
instance using addEventListener()
, like this:
whiteNoiseNode.addEventListener("processorerror", (event) => {
console.error("There was an error!");
});
Alternatively, you can use the onprocessorerror
event handler property to establish a handler for the processorerror
event:
whiteNoiseNode.onprocessorerror = (event) => {
console.error("There was an error!");
};
