Put it in the normal frequency chain
Use either the FilterFreq or FilterFreq Logarithmic preset (Click on edit range, then preset)
Make sure the frequency parameter of the filter is set to 20kHz.
Connect you UI knob to the value parameter (or use the matrix target id). I'm always using the connection wizard, this way it also automatically sets the knob range & suffixes correctly.

@Chazrox start from here:

HISE | Scripting | Buffer

A buffer of floating point data

(docs.hise.audio)

Christoph Hart

@Chazrox no need for a audio player for a simple playback you can just use Engine.playBuffer()

Christoph Hart

@Straticah You need to set

HISE_INCLUDE_PROFILING_TOOLKIT=1

in the projucer when compiling HISE. Have you done that? I'll probably change the default to be enabled soon, but for now I'll leave it disabled by default.

Christoph Hart

Yeah it might be caused by the change to melatonin shadow rendering I did around that time.

I might have introduced a silly mistake though:

If you change this line:

HISE/hi_scripting/scripting/api/ScriptDrawActions.cpp at cdb23d4c24e93ef487127f125742a6443d4e76a2 · christophhart/HISE

GitHub (github.com)

to

p.scaleToFit(a.getX(), a.getY(), a.getWidth(), a.getHeight(), false);

Does that fix the problem?

Christoph Hart

@ustk yup offline spectrum generation can be done with the inbuilt HISE tools:

Content.makeFrontInterface(600, 600);

// Create a buffer with a second length
const var b = Buffer.create(44100.0);

// fill it up with some random signal - two sine sweeps and some noise
reg uptime = 0.0;
reg delta = 0.01;

for(s in b)
{
	s = Math.sin(uptime);
	s += 0.5 * Math.sin(uptime * 2.0);
	s += 0.3 * Math.random();
	
	uptime += delta;
	delta += 0.00003;
}

// Create the FFT object that is used to create the spectrum
const var fft = Engine.createFFT();

// Enable the spectrum generation
fft.setEnableSpectrum2D(true);

// Setup the FFT processing (FFT size & channel count)
fft.prepare(1024, 1);

// Fetch the spectrum options
const var options = fft.getSpectrum2DParameters();

// Dump that
Console.print(trace(options));

// change whatever property you want.
options.ColourScheme = 2;
options.Oversampling = 8;
options.Gamma = 30;
options.ResamplingQuality = "High";

// Send it back
fft.setSpectrum2DParameters(options);

// process the buffer. This creates the spectrum
// that can then be painted
fft.process(b);

// create a panel
const var p = Content.addPanel("P1", 0, 0);

p.set("width", 600);
p.set("height", 600);

p.setPaintRoutine(function(g)
{
	// This function paints the FFT spectrum on the panel
	g.drawFFTSpectrum(fft, this.getLocalBounds(0));
});

@Orvillain yeah, that's really a weird issue - I can reproduce it but also just with the release configuration + LTO - any change to the build flags stop the crash.

I slightly rewrote the code and now it stopped crashing. I don't know why it fixes anything, but let me know if that helps.

Christoph Hart

@Orvillain yes, modulators are monophonic signal generators so they need to compiled with NumChannels==1. -1 indicates that something else went wrong, but it's hard to guess from here.

Oh and I would recommend to check out a better host for testing than a full DAW (unless you specifically need to debug a certain bug that only occurs there), as this vastly accelerates the debug cycle. Check out the JUCE plugin host - you might have to build it with the VST3 SDK from source, but this is a really minimal host that you can directly launch from Xcode and if you save the plugin setup within the host, it will automatically restore it whenever you launch Xcode.

I suppose it isn't terribly useful, but pasting here anyway.

Looks like a release build without symbols, so yeah not much to gain from this.

Christoph Hart

@d-healey but you can do that now. Buttons are distinct elements and will pick up the css while you can style the preset browser with laf functions.

Christoph Hart

@d-healey yes you can combine CSS & laf, but just in the sense that a single LAF object can have a style sheet as well as LAF functions defined and it will pick whatever is there to render the target component. You cannot render CSS & script functions (paint routines or LAF functions) at the same time for a single component.

Note that you can use the ::before and ::after pseudo elements to add some text so if you just want to make a background panel with a header that contains the panel name, this should be doable completely within CSS.
