Faust is here...

[parabuh]

@sletz m1 with new Xcode

[sletz]

@parabuh And how is Faust compiled ?

[Sawer]

Hello Everyone!
I am facing issues when working with Faust in the scriptnode.

In this instance, I was trying to compile the example re.jprev library (by Christoph), however, nothing happened when I compiled it.

Secondly, when I try to click the show SVG popup, the alert window (in the picture) comes out saying that no application can open the .dsp file.

Thirdly, before having this issue, I was also trying to try other libraries. But when compiled nothing happens. Only the jprev was working until the current problem happened, I still do not know what have I done to not make it work anymore.

How can I solve this issue?

Thanks.

@Sawer looks like you’ve not installed it properly. Have you followed the Mac install instructions?

[Sawer]

@Brian
This part is solved, I've enabled the external editor in my settings.

Now I have to figure out why other libraries aren't being processed.

[toxonic]

@Sawer I'm not on Mac, but if you have enabled the external editor option you have to assign the .dsp files to be opened by default with your editor app of choice.
I'm sure, if you click "choose apllication..." you'll be able to choose an editor application.
jprev is not a library, it's a function of the library "reverbs.lib".
if you just use

import("stdfaust.lib");

all standard libraries available will be included.

@Sawer any editor will do then, even just the basic text app works just fine.

[Sawer]

@Brian @toxonic Sorted out, thanks!

[Sawer]

@Sawer
When I use the demos from faust IDE, everything works fine(2x2 channels).
As soon as I try implementing my own parameters, I always get this odd channel mismatch errors.
Same for libraries with 8x8 (it will ask 9x8).

Am I missing something?

[toxonic]

@Sawer Can you post your faust code?

[Sawer]

@toxonic

Here you go, thanks.

[toxonic]

@Sawer indeed, i can't see, where the third input channel comes from. But where did you change the code, respectivly added your parameters?

[Sawer]

@toxonic

import("stdfaust.lib");

process = dm.dattorro_rev_demo;	

This code works.

import("stdfaust.lib");

bw = hslider("BAndWidth",0.5 ,0 , 1,0.1);
inputDiff1 = hslider("Diffusor1",0.5 ,0 ,1 ,0.1);
inputDiff2 = hslider("Diffusor2",0.5 ,0 ,1 ,0.1);
decay = hslider("Decay", 0.5,0 ,1 , 0.1);
decDiff1 = hslider("dDiffusor1",0.5 ,0 ,1 ,0.1);
decDiff2 = hslider("dDiffusor2",0.5 ,0 ,1 ,0.1);
damping = hslider("damping",0.5 ,0 ,1 ,0.1);



process = re.dattorro_rev(bw, inputDiff1, inputDiff2, decay, decDiff1, decDiff2, damping);

This code(with my parameter) doesn't.

[toxonic]

@Sawer i'm actually at work, i'll have a look at it later. Did you already check the SVG diagram (the Button with the eye on the faust node)?

[Sawer]

@toxonic
3x2 Also on the svg.

[toxonic]

@Sawer ahh, okay, i'm still at work, but try to use this as process line instead:

process = _,_:re.dattorro_rev(bw, inputDiff1, inputDiff2, decay, decDiff1, decDiff2, damping);

[Sawer]

@toxonic Trying now, thanks.

[Sawer]

@toxonic

Ahahha, this is way too strange...

[toxonic]

@Sawer Okay, this was not that simple to figure out: There was an error in the description of the reverb in the library. There's missing the parameter for the predelay.
The code should probably rather look like this:

import("stdfaust.lib");

predelay = hslider("Predelay",0.5 ,0 , 1,0.1);
bw = hslider("BandWidth",0.5 ,0 , 1,0.1);
inputDiff1 = hslider("Diffusor1",0.5 ,0 ,1 ,0.1);
inputDiff2 = hslider("Diffusor2",0.5 ,0 ,1 ,0.1);
decay = hslider("Decay", 0.5,0 ,1 , 0.1);
decDiff1 = hslider("dDiffusor1",0.5 ,0 ,1 ,0.1);
decDiff2 = hslider("dDiffusor2",0.5 ,0 ,1 ,0.1);
damping = hslider("damping",0.5 ,0 ,1 ,0.1);



process = re.dattorro_rev(predelay,bw, inputDiff1, inputDiff2, decay, decDiff1, decDiff2, damping);

Note, that this is not really working like it should, because this is just the wet reverb, you would have to add a mixing unit for the dry sound.

[Christoph Hart]

@toxonic or a dry_wet template that does that for you in scriptnode...
