Using On Audio Single Envelope Value without sound

I’m using the On Audio Single Envelope Value to get the amplitude of a sound, but I would like to get that value without having to hear that sound. I thought that by lowering the volume multiplier it would work, but by doing so, it lowers the value of the On Audio Single Envelope Value. How would I be able to keep the same values without having to hear the sound itself.

And is there a way to get the different value of each frequency channel , like the audio visualizer plugin who gives an array.

I have not tested this myself, but, maybe if you use the node “Set sound mix class override” (after you have previously added a submix to your sound), you could override it by Volume set to zero. Then you could try to get the amplitud and see if it virtualizes the amplitud alongside the sound itself. Remember to set “Virtualize when silent” to True inside the Soundwave asset.

I hope this helps.
