vuuuu meter.... vu meter? vu meter master?

@Natanr Try this...I send you a small test project with a filmstrip (107 frames) connected to a Simple Gain Module LevelMeterTest.zip

Then you can replace the filmstrip image with your's and adjust the code and number of frames according to your filmstrip image

@DimitrisSP
Oh Thanks Man Will Do It Right Now

DimitrisSP

@Natanr Happy that i helped!

@DimitrisSP Ha Ha Yes Man This One One Works Thank You ️️️️️

@DimitrisSP Testing this , what is that levelMeterLock ?

Also , any thoughts on how to change this to a mono meter , that is , see both channels on one meter ?

take the input values , sum them and divide by 2....

Since This Made By Sliders, You Need To Place An Empty / Transparent PNG Over The VU Sliders To Avoid Mouse Click / Drags.

@lalalandsynth Sorry for been late to answer...I just now entered in the forum!
In order to have a mono functionality use only one LevelMeter...
Delete ''LevelMeterR'' and rename "LevelMeterL" to "LevelMeter"
Very correctly as @Lindon said ...sum the Left and Right values and divide them by 2...

And as @Natanr said very correctly if you will not use an invisible image like "levelMeterLock" on top of the LevelMeter you will have problems with Mouse Click / Drags.

Its all in the algorithm....maybe a few guys here could help you out.

@DimitrisSP @Natanr @yall

Thanks a lot @DimitrisSP for the vu-meter. I modified it a bit to make whole integers from your png of 107 strips and set it to -100 to +6 dbFS. Also added peak values in labels for both L, R and highest of the two.

Here is that project (scriptnode 2020-08-20): LevelMeterTest--andioak-peak-values.zip

@Christoph-Hart Is there a pan-law compensation built into the Simple Gain module/plugin? To compensate for the increased value from the other channel? The values I get are steep when I pan towards one way, but it might be my programming here. (and my gain is +1, but at Left 40:ish i get around 5-6 db over the center peak, that´s about what pan law should compensate for...) (and the gif below is 7fps :) )

Here it is:

Script of this thing:

Content.makeFrontInterface(600, 500);

const var LevelMeterL = Content.getComponent("LevelMeterL");
const var LevelMeterR = Content.getComponent("LevelMeterR");
const var LevelMeterLock = Content.getComponent("LevelMeterLock");

// show values as well, via label with whole integer db values.
const var Label_MeterValue = Content.getComponent("Label_MeterValue"); // the peak of the strongest channel. 
const var Label_MeterValue_L = Content.getComponent("Label_MeterValue_L");
const var Label_MeterValue_R = Content.getComponent("Label_MeterValue_R");



// ------------

const var Pan = Content.getComponent("Pan");

const var SimpleGain1 = Synth.getEffect("SimpleGain1");

//Decay Rate
const var DECAY_RATE = 0.93;

//Current Values
var curLevelL = 0.0;
var curLevelR = 0.0;
var curLevelM = 0.0;

//Timer Callback
const var t = Engine.createTimerObject();

t.setTimerCallback(function()
{
//Synth Values
  var LevelL = SimpleGain1.getCurrentLevel(1);  
  var LevelR = SimpleGain1.getCurrentLevel(0);
  
//Peak Synth Values  
  var peakLevelL = Math.max(LevelL, LevelL);  
  var peakLevelR = Math.max(LevelR, LevelR);
  
  var peakLevelMax = Math.max(LevelL, LevelR);

//Kick Left  
//-----------------------------------------------------------------------------  
  if (peakLevelL > curLevelL)
    {
      curLevelL = peakLevelL;
    }
  else
    {
      curLevelL *= DECAY_RATE;
    }

//Kick Right  
//-----------------------------------------------------------------------------     
  if (peakLevelR > curLevelR)
    {
      curLevelR = peakLevelR;
    }
  else
    {
      curLevelR *= DECAY_RATE;
    }
    
//Kick Max peak for mono out or label with max peak for strongest channel.
//-----------------------------------------------------------------------------     
  if (peakLevelMax > curLevelM)
    {
      curLevelM = peakLevelMax;
    }
  else
    {
      curLevelM *= DECAY_RATE;
    }

  
//Decibel Conversion  
//-----------------------------------------------------------------------------   
  LevelL = Engine.getDecibelsForGainFactor(curLevelL);  
  LevelR = Engine.getDecibelsForGainFactor(curLevelR);
  var LevelMax = Engine.getDecibelsForGainFactor(curLevelM);
  
//Set Values  
//----------------------------------------------------------------------------
  LevelMeterL.setValue(LevelL);  
  LevelMeterR.setValue(LevelR);
  
  Label_MeterValue.set("text", (LevelMax >= -99) ? Math.round(LevelMax) : -100); // use Math.round (round up) for all except minimum value, -100. 
  Label_MeterValue_L.set("text", (LevelL >= -99) ? Math.round(LevelL) : -100);
  Label_MeterValue_R.set("text", (LevelR >= -99) ? Math.round(LevelR) : -100); 
  
});

t.startTimer(30);

UPDATE: this code does what it´s supposed to, but using labels to be updated by a timer seems to crash hise and the output plugins/standalone exported instruments. Read here about it.

@andioak Apparently there's a 3db compensation law but not sure...


float BalanceCalculator::getGainFactorForBalance(float balanceValue, bool calculateLeftChannel)
{
	if (balanceValue == 0.0f) return 1.0f;

	const float balance = jlimit(-1.0f, 1.0f, balanceValue / 100.0f);

	float panValue = (float_Pi * (balance + 1.0f)) * 0.25f;

	return 1.41421356237309504880f * (calculateLeftChannel ? cosf(panValue) : sinf(panValue));
}

void BalanceCalculator::processBuffer(AudioSampleBuffer &stereoBuffer, float *panValues, int startSample, int numSamples)
{
	FloatVectorOperations::multiply(panValues + startSample, float_Pi * 0.5f, numSamples);

	stereoBuffer.applyGain(1.4142f); // +3dB for equal power...

	float *l = stereoBuffer.getWritePointer(0, startSample);
	float *r = stereoBuffer.getWritePointer(1, startSample);

	while (--numSamples >= 0)
	{
		*l++ *= cosf(*panValues) * 1.4142f;
		*r++ *= sinf(*panValues);

		panValues++;
	}
}

@ustk thanks. whoah.. math is beyond my scope atm, but pan law I thought would remove the 3db. Not add it as suggested there. I got that wrong though, as pan law is the opposite.

vuuuu meter.... vu meter? vu meter master?
