How to handle the volume of a source with obs-studio-node lib

Question

The initial volume is set to 1. After setting it to 0, I can't get it back to 1 despite all my trials. I also would like to modulate the volume with intermediate levels but it only goes to 0 when I try.

// example
console.log(item.source.volume) // 1
item.source.volume = 0
console.log(item.source.volume) // 0
item.source.volume = 1
console.log(item.source.volume) // 0

Answer 1

You need to attach a fader:

const source = osn.InputFactory.create(...);
const fader = osn.FaderFactory.create(0); //Create a cubic fader
fader.attach(source);
fader.mul = 0.2; //Your volume from 0 - 1

spent hours trying to do this
