BaseAudioContext: destination property

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.

The destination property of the BaseAudioContext interface returns an AudioDestinationNode representing the final destination of all audio in the context. It often represents an actual audio-rendering device such as your device's speakers.

Value

An AudioDestinationNode.

Examples

Note: For more complete applied examples/information, check out our Voice-change-O-matic demo (see app.js lines 108–193 for relevant code).

const audioCtx = new AudioContext();
// Older webkit/blink browsers require a prefix

const oscillatorNode = audioCtx.createOscillator();
const gainNode = audioCtx.createGain();

oscillatorNode.connect(gainNode);
gainNode.connect(audioCtx.destination);
