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
