Decibels --> Paint Routine 'Alpha'?

[Chazrox]

Can someone help me with this paint routine? I just want to paint a panel and use 'decibelsForGainFactor' for Alpha values in my paint routine.

I just want to to work like this, when the decibels are > -10db and < -12db, the panel blinks.

Like one of these....

I dont need the peak meter, I just need this part to blink when it hits target level/threshold.
Its just a rectangle behind the meter.

@Chazrox gottem.

const var Image8 = Content.getComponent("Image8");
const var t4 = Engine.createTimerObject();
const var InGain = Synth.getEffect("InGain");
t4.setTimerCallback(function()
{	
	var v4 = InGain.getCurrentLevel([0,1]);
	v4 = Engine.getDecibelsForGainFactor(v4);
	if (v4 > -12)
	{
	Image8.setAlpha(v4 * v4 / 101);		
	}
	
});

t4.startTimer(11);
