AudioNode: numberOfOutputs property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨July 2015⁩.

The numberOfOutputs property of the AudioNode interface returns the number of outputs coming out of the node. Destination nodes — like AudioDestinationNode — have a value of 0 for this attribute.

Value

An integer ≥ 0.

Examples

const audioCtx = new AudioContext();  const oscillator = audioCtx.createOscillator(); const gainNode = audioCtx.createGain();  oscillator.connect(gainNode).connect(audioCtx.destination);  console.log(oscillator.numberOfOutputs); // 1 console.log(gainNode.numberOfOutputs); // 1 console.log(audioCtx.destination.numberOfOutputs); // 0
