{{securecontext_header}}{{APIRef("WebCodecs API")}}{{SeeCompatTable}}

The dequeue event of the {{domxref("AudioEncoder")}} interface fires to signal a decrease in {{domxref("AudioEncoder.encodeQueueSize")}}.

This eliminates the need for developers to use a {{domxref("setTimeout", "setTimeout()")}} poll to determine when the queue has decreased, and more work should be queued up.

Syntax

Use the event name in methods like {{domxref("EventTarget.addEventListener", "addEventListener()")}}, or set an event handler property.

addEventListener("dequeue", (event) => {});

ondequeue = (event) => {};

Example

audioEncoder.addEventListener("dequeue", (event) => {
  // Queue up more encoding work
});
