AudioWorkletNode: processorerror event

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.

js

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:

js

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:

js

whiteNoiseNode.onprocessorerror = (event) => {
  console.error("There was an error!");
};
