FAUST Stereo Limiter 1176 Help needed

[DabDab]

I need to create FAUST Limiter. But I am unable to assign controllers.

Here is my Code :

import ("stdfaust.lib");
Ratios = hslider ("Ratio", 4,4,20,1);
Att = hslider ("Attack",40,20,800,0.1);
Rel = hslider ("Release", 50,50,1100,0.1);
process = co.limiter_1176_R4_stereo;

What I am doing wrong ?

@DabDab Your method looks ok when it's compared to here: https://faustlibraries.grame.fr/libs/compressors/#colimiter_1176_r4_stereo

I am also interested how to use that compressor in Faust also.

Hmm, the params dont seem to be assigned.. maybe try:

import ("stdfaust.lib");
Ratios = hslider ("Ratio", 4,4,20,1);
Att = hslider ("Attack",40,20,800,0.1);
Rel = hslider ("Release", 50,50,1100,0.1);
process = co.limiter_1176_R4_stereo(Ratios,Att,Rel);

tho the documentation does say:

This example is intended to get you started using compressor_* as a limiter, so all parameters are hardwired to nominal values here

@Lindon so looking in the Faust lib we end up here:

limiter_1176_R4_stereo = compressor_stereo(4,-6,0.0008,0.5);

so if you substitute the compresor_stereo:

_,_ : compressor_stereo(ratio,thresh,att,rel) : _,_

it would be the same thing no? If so its not really an 1174 compressor is it...

Acording to here: https://faustlibraries.grame.fr/libs/compressors/#colimiter_1176_r4_stereo

compressor_stereo and limiter_1176_R4_stereo are not the same things. Are they?

[Lindon]

@harris-rosendahl go to line 996 here:

https://github.com/grame-cncm/faustlibraries/blob/master/compressors.lib

and see they are the same thing.

[harris rosendahl]

@Lindon Thank you for the info!

[sletz]

compressor_stereo is the generic algo with 4 parameters, limiter_1176_R4_stereois a specialized version with chosen value for those 4 parameters.

[harris rosendahl]

@sletz Is Faust engine stable enough with Hise to release commercial products?

I am interested in the Wave Digital Models and ready to use Faust libraries.

But as I see Faust doesn't work stable in Hise and causes lots of daw crashes with the compiled plugins.

Can you please fix these stability and also even the installation issues (Intel-M1 Macs and Windows), so it would be great to use Faust in here.

Nope.. This will not work. Still I am confused how to assign/get all the Limiter parameters ?

@DabDab

'1176' is just an abstraction of the stock compressor, here is an example in script form that does work which might give you a better idea:

import("stdfaust.lib");
ratio = hslider("ratio",4,0,20,0.01);
thresh = hslider("threshold",-5,-30,0,0.01);
att = hslider("attack",2,0,10,0.01);
rel = hslider("release",2,0,5,0.01);
limiter1176 = _, _ : co.compressor_stereo(ratio,thresh,att,rel): _, _ ;

process = limiter1176;

@harris-rosendahl What version of FAUST are you using? And do you have a simple HISE project example that we can use to test with? Also, what specific issues do you get with installation, are you referring to installing the FAUST assets or a compiled plugin that has FAUST dsp code embedded?

[DabDab]

@Brian I am talking about FAUST limiter. How do I use co.limiter_1176_R4_stereo FAUST Function ? co.limiter_1176_R4_stereo doesn't accept any parameters.

[Brian]

@DabDab co.limiter_1176_R4_stereo IS co.compressor but with fixed values to serve as an example, the script I provided gives control parameters to that exact compression algorithm.
