AudioWorkletNode: processorerror event
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2021.
Secure context: This feature is available only insecure contexts (HTTPS), in some or allsupporting browsers.
Theprocessorerror event fires when the underlyingAudioWorkletProcessor behind the node throws an exception in its constructor, theprocess 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 likeaddEventListener(), or set an event handler property.
addEventListener("processorerror", (event) => { })onprocessorerror = (event) => { }Event type
A genericEvent.
Examples
To be informed when the processor throws an exception, you can add a handler to yourAudioWorkletNode instance usingaddEventListener(), like this:
whiteNoiseNode.addEventListener("processorerror", (event) => { console.error("There was an error!");});Alternatively, you can use theonprocessorerror event handler property to establish a handler for theprocessorerror event:
whiteNoiseNode.onprocessorerror = (event) => { console.error("There was an error!");};Specifications
