+
+The **`port`** read-only property of the {{domxref("AudioWorklet")}} interface returns a {{domxref("MessagePort")}} object that can be used to send and receive messages between the main thread and the associated {{domxref("AudioWorkletGlobalScope")}}.
+
+This allows for custom, asynchronous communication between code in the main thread and the global scope of an audio worklet, such as receiving control data or global settings.
+
+## Value
+
+The {{domxref("MessagePort")}} object connecting the `AudioWorklet` and its associated `AudioWorkletGlobalScope`.
+
+## Examples
+
+See [`AudioWorkletNode.port`](/en-US/docs/Web/API/AudioWorkletNode/port#examples) for more examples.
+
+### Using a port for global messages
+
+In the following example, we can use `port.onmessage` to receive data and `port.postMessage` to send data:
+
+```js
+const context = new AudioContext();
+// Load the module that contains worklet code
+await context.audioWorklet.addModule("processor.js");
+
+// Listener for messages from AudioWorkletGlobalScope
+context.audioWorklet.port.onmessage = (event) => {
+  console.log("Message from global worklet:", event.data);
+};
+
+// Set a global config, for example:
+context.audioWorklet.port.postMessage({
+  volume: 0.8,
+});
+```
