How to smooth a path + Ducking Display Script

HISEnberg

@ustk Have I missed something? I am just getting errors trying to use the roundCorners.

        // Invert the path vertically and scale by duck
        p.scaleToFit(a[0], h  , a[2], -h, false); 
	local roundedPath = p.roundCorners(10.0);
		
 	// Fill
 	g.fillAll(panel.get("bgColour"));
         g.setColour(Colours.white);
         g.drawPath(roundedPath, p.getBounds(1.0), {"Thickness": 2.0});

ustk

@HISEnberg not as far as I can see
except p.getBounds(1.0) that should use roundedPath but this shouldn't lead to an error...

ustk

@HISEnberg So it appear there's no need to create another path... I don't where I get that, I was sure it was the case when I implemented it, it's even written in the description...

But there's something that you can't round. There are too many points, so the rounding will happen at the pixel size. you need more space between the points so the curve can smooth out freely

ustk

@HISEnberg did this and got rounding:

     pnl_DuckingDisplay2.setPaintRoutine(function(g)
     {
         var h = this.getHeight();
         
         // path is restrained to a width of 60 so it is created with less points (rescaled later)
         var p = BUF_DUCKING.createPath([220,0,60,200], [0, 1, 0, 0], 0.0);
 
         // Invert the path vertically and scale by duck
         p.scaleToFit(0, h, this.getWidth(), -h, false);
	
 	 g.fillAll(this.get("bgColour"));
         
         g.setColour(0xFFFFAE00);
         g.drawPath(p, p.getBounds(1.0), {"Thickness": 0.5});
         
         g.setColour(0xFF00ff00);
         p.roundCorners(100.0); // set to 100 so it rounds up to the next point, which is way closer. so 100 is just a limit we never reach here
         g.drawPath(p, p.getBounds(1.0), {"Thickness": 0.5});
     });

I don't want to interrupt your Path manipulation party, but I think that should be solved on the DSP side.

I know I can add some smoothing within my scriptnode chain to get similar results, but in this particular case it comes with the drawback of loosing the information of the attacks.

If that's your only problem, use an envelope follower with a short attack time instead of a smoother (an envelope follower is basically the same but with two different times for upwards and downwards smoothing).

HISEnberg

@Christoph-Hart thank you the envelope follower should be a better solution!

@ustk thanks for taking the time to script these!

Thank you guys these are both great suggestions!

Christoph I am actually seeing that the envelope follower is producing more noise in the signal than the peak node. Here is an example of one arpeggiated sine wave gating another sine wave:

Sorry for bringing this topic back to life.

I want to make a peak oscilloscope using the rounding script of @ustk that shows only the upper position of the sound. But the max. peak level does not go beyond half the height of the panel.

What should I do to get it to full height?

@JulesV The problem is the createPath, try this:

    var z = db_pkMeter.createPath([100,0,150,200], [0, 1, 1, 0], 0.0);
