The numberOfInputs
property of the AudioNode
interface returns the number of inputs feeding the node. Source nodes are defined as nodes having a numberOfInputs
property with a value of 0.
Syntax
var numInputs = audioNode.numberOfInputs;
Value
An integer ≥ 0.
Example
const audioCtx = new AudioContext(); const oscillator = audioCtx.createOscillator(); const gainNode = audioCtx.createGain(); oscillator.connect(gainNode).connect(audioCtx.destination); console.log(oscillator.numberOfInputs); // 0 console.log(gainNode.numberOfInputs); // 1 console.log(audioCtx.destination.numberOfInputs); // 1
