[Faudiostream-users] Faust Conference (IFC) 2024 in Turin, Italy, on November 21-22, 2024.

[Stéphane Letz]

Soundmit announces that it will host the International Faust Conference (IFC) 
2024 in Turin, Italy, on November 21-22, 2024. The IFC is a biennial event that 
brings together the global community of developers and users of the FAUST audio 
programming language. The conference offers a unique opportunity to: 

Learn more about the FAUST language and its various applications Meet other 
professionals in the audio and music industry Attend talks, workshops, and 
panels on a variety of topics related to FAUST Contribute to the future 
development of the language The IFC 2024 will be held two days before the 14th 
edition of Soundmit, the international fair on synthesizers, electronic musical 
instruments, digital music and sound art, which will take place in Turin on 
November 23-24, 2024. The two events will be united for the first time, 
creating a unique opportunity for participants to fully immerse themselves in 
the world of digital audio. 

Companies that wish to support the conference can do so with a small 
sponsorship that offers a great return in terms of visibility. It is also 
possible to participate in the Soundmit as an exhibitor to present your 
products and services to an international audience of professionals. 

 Dates: IFC24 - 21/22 Nov 2024 - Turin

Re: [Faudiostream-users] Using Faust export in C'74 Max gen~ codebox?

[Stéphane Letz]

No, codebox is a somewhat an «improved gen~ » language, and cannot be used 
within gen~.

(the initial idea what to have a Faust => gen~, backend, to be usable in both 
MSP *and* RNBO contexts, but it appeared that gen~ was not complete enough to 
support all needed primitives. Thus the choice of within Faust => codebox 
backend, to be only usable in RNBO patches.)

The VST export is old and unmaintained. Better use the JUCE export and compile 
for VST3.

See : https://github.com/grame-cncm/faust/tree/master-dev/architecture/juce

Note that the JUCE project can be directly exported from the faust Web IDE: 
https://faustide.grame.fr (and https://github.com/grame-cncm/faustide for the

Re: [Faudiostream-users] emsc error

[Stéphane Letz]

The lowpass first parameter 
(https://faustlibraries.grame.fr/libs/filters/#filowpass) has to be a « 
nonnegative constant numerical expression » , see : 
https://faustdoc.grame.fr/manual/syntax/#constant-numerical-expressions

So a slider cannot be used here. 

The reported error should be «  ERROR : stack overflow in eval », but for some 
reason the libfaust version in WebAssembly does not report it correctly for now.

Not sure to fully understand the logic, but looking at the C++ generated file,

Try to simplify the code as much as possible, and looking at the SVG diagram

I agree with Oleg here:

- Integers in Faust are 32-bits integer with all their « properties »,  which 
are currently used in the library no.noise generator using the wrapping 
behaviour (maybe not the best idea we had, but well…)

- math operations on integers stay in the Integer domain in general. The / 
(division) only promotes both arguments as float as does a float division.

- some other primitive do « type promotion ». This has been better documented 
here : https://faustdoc.grame.fr/manual/syntax, with something like « 
automatically promoted to int » at several places 

- we can not afford to change the behaviour of integers in -double mode as 
Dario suggested, since it would instantly break existing code in a « blind » 
manner. 

- do we need an *explicit new option* to set the integer size (like -int32, 
-in64 or better possibly -int N, with N = 32, 64, 128 one day ?), so as a *user 
choice* ? But that 1) would break no.noise implementation, so we would need to 
write alterable version… 2) this could blindly break existing code….

Comments ?

Re: [Faudiostream-users] Int signals compiling with -double

[Stéphane Letz]

1) https://faustdoc.grame.fr/manual/syntax/#numbers is quite clear AFAICS:

==
Numbers

Faust considers two types of numbers: integers and floats. Integers are 
implemented as signed 32-bits integers, and floats are implemented either with 
a simple, double, or extended precision depending of the compiler options. 
Floats are available in decimal or scientific notation. 

Like any other Faust expression, numbers are signal processors. For example the 
number 0.95 is a signal processor of type 핊0→핊1 that transforms an empty tuple 
of signals () into a 1-tuple of signals (y) such that ∀t∈ℕ,y(t)=0.95.

Operations on integer numbers follow the standard C semantic for +, -, * 
operations and can possibly overflow if the result cannot be represented as a 
32-bits integer. The / operation is treated separately and cast both of its 
arguments to floats before doing the division, and thus the result takes the 
float type.
==

Should be add something more ?

2) In a more long term : do we really need 64 bits integer ? Or forcing 
compilation as real ( -single/double/quad) when needed is enough ?

3) We have to fix Dario just reported issue : 
https://github.com/grame-cncm/faust/issues/962

[Faudiostream-users] faust-web-component released

[Stéphane Letz]

As result of Ian Clester Google Summer of Code work 
(https://ijc8.me/2023/08/27/gsoc-faust/), a Faust web component which 
integrates the libfaust JS/WebAssembly compiler has been developed. The 
faust-web-component package provides two web components for embedding 
interactive Faust snippets in web pages:

 •  displays an editor (using CodeMirror 6) with executable, 
editable Faust code, along with some bells & whistles (controls, block diagram, 
plots) in a side pane. This component is ideal for demonstrating some code in 
Faust and allowing the reader to try it out and tweak it themselves without 
having to leave the page. (For more extensive work, it also includes a button 
to open the code in the Faust IDE.) 

 •  just shows the controls and does not allow editing, so it 
serves simply as a way to embed interactive DSP. 

More info on the GitHub page: https://github.com/grame-cncm/faust-web-component 
or NPM package: https://www.npmjs.com/package/@grame/faust-web-component

[Faudiostream-users] First version of JSFX backend added in the compiler

[Stéphane Letz]

Hi People,

JSFX is the scripting language included in the Reaper DAW: 
https://www.reaper.fm/sdk/js/js.php

Contributed by Johan Philippe, the Faust JSFX backend first version is 
available. 

You can now export JSFX on Faust Web IDE: https://faustide.grame.fr/, or by 
building last Faust versions and using -lang jsfx option with Faust command 
line. Currently does not support MIDI polyphonic mode (soon coming).

[Faudiostream-users] : Two Google Summer of Code projects attributed to GRAME for Faust

[Stéphane Letz]

 May 04, 2023: Two Google Summer of Code projects attributed

Two Google Summer of Code projects have finally been attributed to GRAME:

- «  Automatic Differentiation in the Faust Compiler »  aims at adding 
Automatic differentiation directly in the compiler, so that gradient 
calculation can be carried out natively in Faust, with applications in Machine 
Learning algorithms. The project will be worked on by Thomas Rushton.

- «  Better Faust on the Web »  aims at enhancing Faust’s support for the web 
platform: transition the Faust web tools to a rewritten TypeScript version, 
extend the Faust Web IDE, enhance Faust’s online documentation, and prototype 
an experimental platform for sharing Faust code on the web. The project will be 
worked on by Ian Clester.

Welcome to both of you in the Faust community !

Well look at the generated code. I did, looking at LLVM IR, and some of the 
delay lines related loops got simply rewritten using LLVM memmove intrinsic 
(https://llvm.org/docs/LangRef.html#llvm-memmove-intrinsic)

Hi Henrik, 

Yes, this is a known problem: compiled binaries are not correctly 
self-contained. David Braun is working on improving the situation using GitHub 
actions. You can possibly test the precompiled 2.58.11 version here:

Re: [Faudiostream-users] Triangle LFO with controllable phase?

[Stéphane Letz]

Two different issues here:

1) first the code defines a same path for a slider and a bargraph. The old rule 
of « not 2 same paths in the GUI » was somewhat relaxed in this commit:  
https://github.com/grame-cncm/faust/commit/3437255f54ec46c565c159438bde19c3daea757c,
 but still not completely correctly. So I’ve have to fix that. In the meantime 
the code can compile if the DSP is fixed this way:

import("stdfaust.lib");
lf_triangle_phase(freq, phase) = os.lf_triangle(freq) @ (phase * ma.SR/freq);
lfo_freq = hslider("[1] Freq", 0.5, 0.001, 50, 0.01);
lfo1 = lf_triangle_phase(lfo_freq, 0);
lfo_phase = hslider("[2] Phase", 180, 0, 360, 1) / 360;
lfo2 = lf_triangle_phase(lfo_freq, lfo_phase);
process =  lfo1, lfo2 : hbargraph("[3] 0",-1,1), hbargraph("[4] Phase1",-1,1);

2) but then another issue happens: the allocated memory for the delay (@ (phase 
* ma.SR/freq); ) is too big for the wasm memory allocation scheme. So this has 
to be fixed also at DSP code level.

Re: [Faudiostream-users] faust2vcvrack force x86

[Stéphane Letz]

Automatically generated by StepGPT (so may be wrong… ((-; )

Probably by:

- getting x64 version of the SDK : 
https://vcvrack.com/downloads/Rack-SDK-2.2.3-mac-x64.zip

- using «  arch -x86_64 /bin/bash » trick to have your terminal then run Intel 
like

- faust2vcvrack -version 2  foo.dsp or faust2vcvrack -version 2 -source foo.dsp 
and compile yourself.

- test and report

The VSC extension  as not been updated since a bit of time, so better use the 
Web IDE if possible.

And you can also use the Faust Slack or Discord channels (see 
https://faust.grame.fr/community/help/) to get help from the Faust community.

Maybe using OSC control would be faster in this case ?

Yes indeed.

Yes. Reloading the https://faustide.grame.fr/ URL restores the set of 
previously loaded DSP files (.dsp files), and possibly users libraries (.lib 
files)

Re: [Faudiostream-users] Faust intermediate code?

[Stéphane Letz]

Hi Georg,

This code is a self-contained expanded version that embeds all needed 
libraries, currently sent by the Faust Web IDE client side to the remote 
compilation service. The need is when we want to allow developers to use their 
own client side Faust libraries.

It is not really possible to convert it back to the original form..

The real solution on our side is to send the DSP + all needed libraries as a 
ZIP archive to the remote compilation service. Not yet done...

Here: https://github.com/grame-cncm/faustlive/releases/tag/2.5.12

The macOS binary is still not signed. On Apple Silicon, you can simply open it 
under Rosetta: right-click the first time then normal open later on.

Most faust2xx tools are bash commands that do not work well on Windows. The 
best is probably to install a Linux VM and start from there.

Re: [Faudiostream-users] faust2wwise

[Stéphane Letz]

Hi João,

The faust2wwise repository contains a set of files which are a starting point 
to develop a faust2wwise tool and a plugins embedding the libfaust library.

We don't have the necessary resources to work on it right now, but help is 
welcome of course ((-; and diffusing the existence of this starting project in 
the Wwise community might help.

Is libmicrohttpd correctly installed ?

https://github.com/grame-cncm/faustlive/blob/0dd0d86df19c1dc822c106908869cf720128e43d/Build/README.md

I not do it, then clean and recompile Faust first.

Re: [Faudiostream-users] trouble building faustlive

[Stéphane Letz]

Are you build FL from the git repository? Or from a release package ? Which 
version ?

When compiling from the Git repository, the 
'/home/ks/Install/faustlive/Resources/Libs/ folder is actually a Git submodule 
and should contain all the xx.lib libraries files. Is this the case?

Re: [Faudiostream-users] problem building VST3 via JUCE, AU works

[Stéphane Letz]

It seems the -double does not work correctly with VST3 format, but work OK with 
AU.

 Tested with simpler examples here. Can you confirm that ? (even if you DSP 
confirm needs -double in the first place…)

[Faudiostream-users] May 20, 2022: Two Google Summer of Code projects attributed

[Stéphane Letz]

Faust News

>> May 20, 2022: Two Google Summer of Code projects attributed

Two projects have finally been attributed to GRAME:

• Faust Integration in HISE aims at integrating support for the Faust 
audio programming language into HISE, an extensive framework for the creation 
of sample-based virtual musical instruments. The project will be worked on by 
Roman Sommer.

• Integrating Faust Into the Bespoke DAW aims at extending the modular 
Bespoke engine with Faust, allowing for both static compilation of modules, and 
potentially dynamic programming within Bespoke. The project will be worked on 
by Drew James.

Welcome to both of you in the Faust community !

Re: [Faudiostream-users] MPE And Faust

[Stéphane Letz]

We currently don't have architecture code to handle MPE, since support MPE is a 
huge work.

I would suggest to target JUCE (supporting MPE) using the faust2juce tool 
(https://github.com/grame-cncm/faust/tree/master-dev/architecture/juce)

You can drag/drop each .lib file in the « Project Files » section, then use

We started a list of possible projects here: 
https://github.com/grame-cncm/faustideas/blob/master/README.md but we at GRAME 
can possibly mentor 1 or 2 projects only.

Additional project ideas and the associated mentors can possibly be added at
