Here is a simple sinefold distortion, with a hardclip threshold

//Xander'
import("stdfaust.lib");

//sinefold function
distortion(x) = aa.sine(strength * x) 
with {
	strength = hslider("strength", 1, 1,100,0.01) : si.smooth(0.999);
};

//clip function
clip = min(thresh_linear) : max(0 - thresh_linear)
with {
	threshold = hslider("threshold", -0.3, -100,0, 0.01) : si.smooth(0.999);
	thresh_linear = pow(10, threshold/ 20);
}; 

//variable for individual input, including effect and input and output gain
stereo = *(pregain_linear) : (distortion : clip) * postgain_linear
with {

	pregain = hslider("pregain", 1, -100,20,0.01) : si.smooth(0.999);
	pregain_linear = ba.db2linear(pregain);

	postgain = hslider("postgain", 0, -100,20,0.01) : si.smooth(0.999);
	postgain_linear = ba.db2linear(postgain);
};

process = stereo, stereo;

This is just a super simple stereo dropout effect, but I hope it can be of help to someone to get an idea on how to do it. If you have any ideas to improve it let me know!

//======================================================= dropouts
clamp(nmin, nmax) = min(nmax) : max(nmin);

dropout_noiseL(rate) =
    lfnoise(rate+0.6) + lfnoise(rate) : clamp(0, 1);
dropout_noiseR(rate) =
    lfnoise(rate+0.5) + lfnoise(rate) : clamp(0, 1);


//dropout_curve, number between 1.2 and 10
dropout_nonlinear(rate, intensity, dropout_curve, phase) = 
    -tanh(
    ba.if(phase < 1, 
    dropout_noiseL(rate),
    dropout_noiseR(rate))
    * dropout_curve - dropout_curve)
    + (1 - intensity);


dropout(phase, x) = x * (dropout_nonlinear(r, strength, curve, phase))
with{
    r = hslider("rate", 1, 0.4, 10, 0.01);

In HISE version 3.6, when I used a floating tile set to audio analyser (specifically the spectral analyser or index 2), I could easily run higher sample sizes with 0 to no lag. In HISE 4, however, if the spectral analyser has a sample size higher or equal to 8192, it causes the program to drop a huge amount of frames (this is not a PC thing; my RAM and my CPU are barely touched). Is there some setting I can change to fix this issue?

@ustk This didn't fix it completely, but it definitely helped a lot, thank you

@Christoph-Hart, I'm developing in Windows, and it seems to correlate directly to how fast my PC is running. Now, I am doing this with knobs. Would turning them into Lottie animations fix this, possibly?

I am working on a cassette plugin that has wheels that are animated. For some reason, the wheels stutter and aren't smooth. I'm thinking the culprit is the absence of delta time, but I'm not sure. This is the code:

Content.makeFrontInterface(900, 600);

const var wheel_timer = Engine.createTimerObject();
const var wheel = Content.getComponent("wheel");
const var wheel1_b = Content.getComponent("wheel1_b");
const var wheel2_b = Content.getComponent("wheel2_b");


const var wheel2 = Content.getComponent("wheel2");
var i = 100;
var j = 100;

wheel_timer.setTimerCallback(function()
{
	i = i - 1;
	
	if (i%2 == 0) {
		j -= 1;
	};
	
	if (i > 1) {	
		wheel.setValue(i);
		wheel2_b.setValue(i);
	} else {
		i = 100;
	};
	
	if (j > 1) {	
			wheel2.setValue(j);
			wheel1_b.setValue(j);
		} else {
			j = 100;
		};
	
	
});

wheel_timer.startTimer(20);

@griffinboy Will do! If you have any resources you could point me towards, it'd be a big help

I have created a simple saw wave here.
When the saw wave happens to produce frequencies above half the sample rate the frequencies fold so all the higher notes sound very ugly. Is there anyway I can create a fix for this in Faust?

// xander
import("stdfaust.lib");

// midi controls
freq = hslider("freq", 440, 1, 16000, 1);
t = button("gate");

// simple phasor
phasor(f) = (+(freq / ma.SR)) ~ ma.frac;

// subtle smoothing
saw(f) = sin(phasor(f) * 2.0 - 1.0);

// signal
signal = saw(freq) * en.adsr(0.01, 1.5, 0.5, 1, t);

// subtle harmonics
tape(x) = x + aa.sine2(x^3) / 3;

// process
process = tape(signal), tape(signal);

@d-healey Thank you! Makes sense, guess I can hardcode the parameter values.

@d-healey Yes, not via code, but just with the side panel.

Having issues with setControlCallback not working with knob. When I change the knob it is not calling the controlback function at all (I've tried Console.Print("..") in the inline function and it didn't print anything). Am I missing something, or is this something you can't do? (And yes I have tried timers, they cause Hise to crash for some reason).

const var decay_time_label = Content.getComponent("decay_time_label");
const var decayTime = Content.getComponent("decay_time");


inline function onDecayControl(component,value)
{
	decay_time_label.set("text", decayTime.getValue());
};

decayTime.setControlCallback(onDecayControl);
