AudioWorkletNode.onprocessorerror

The onprocessorerror property of the AudioWorkletNode interface defines an event handler function to be called when the processorerror event fires. This occurs 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.

audioWorkletNode.onprocessorerror = function() { ... };
