For anyone who wants it.
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!

import("stdfaust.lib");
import("noises.lib");

process = signalL, signalR;

//======================================================= 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);
    strength = hslider("intensity", 0, 0, 1, 0.01);
    curve = hslider("curve", 4, 1.4, 10, 0.01);
};

signalL = dropout(0);
signalR = dropout(2);

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?
