@Stephane Letz, Are you aware of any timeline to update the FAUST IDE, allowing it to compile for Apple Silicon?
-
Thx @Stephane Letz for reply. Will follow your suggestions and get back to you. ....... Had issues logging in to Git (day of CrowdStrike outage), but looks like I'm good to go.

The Faust IDE does not yet compile for Apple Silicon. In the meantime you’ve have to install Faust and Max SDK locally to compile a native version, see: https://github.com/grame-cncm/faust/tree/master-dev/architecture/max-msp Stéphane Le 19 juil. 2024 à 15:59, DAS dndrew@users.sourceforge.net a écrit : 19 July, 2024 Greetings, Cycling'74 released Max 8.6.4 in July of this year.

19 July, 2024 Greetings, Cycling'74 released Max 8.6.4 in July of this year. Max externals, which were compiled with FAUST IDE no longer function. For each FAUST programme, Max reports "could not load due to incorrect architecture". Support services at Cycling'74 is asking me to reach out to FAUST dev team. Can anyone confirm this behaviour on their computer and does the compiling code (in FAUST IDE) need to be examined in relation to latest release of Max 8.6.4? Running Macbook Pro, OSX 14.5, Apple...

Thanks for your reply. However afaik this only allows to pass an integer as a label name. If I want to name my slider "Foo", I cannot pass "Foo" as an argument of that function.

Thanks Julius - It's great to see that this contributed in some way to FAUST in general. I found the video helpful as well. Things have been progressing nicely on our end.

Wow, thank you Julius!! This works! We are using this in a filter chain that is used in the analysis of biophysical signals captured at audio rate. This was a key componet in going forward. Faust will enable us to share our work on a variety of platforms. (see: http://www.ndstudiolab.com/pacis). Hopefully the slew limiter is useful to others as well. Kind regards, Mark-David

Spoiler alert: This might be a complete slew limiter: slew_limiter(slopeMax) = (+ : step_calc(slopeMax) : (+~_))~*(-1) with { step_calc(slopeMax,xmy) = xmy <: min(slopeMax),max(-slopeMax) : select2(xmy<0); }; On Tue, Sep 15, 2020 at 10:09 PM Julius O.

I cannot resist little Faust puzzles like this. Here is a solution for rising slew limiting: slew_lim_plus(dxm,x) = x,dxm : (+, : min : (+~))~*(-1); // where dxm = maximum upgoing slope To derive this, I followed the logic in the theorem that proves Faust can encode any block diagram (one of the early papers). Including falling slew-limiting is left as an exercise. Possibly useless hint: slew_lim_minus(dxm,x) = -slew_lim_plus(dxm,-x); Isn't Faust fun? On Sun, Sep 13, 2020 at 8:10 PM Mark-David Hosale...

Thank you again Julius for your previous reponse. Honestly - I wasn't able to get any results from the above, but I am not sure if I understand how to implement what your describing. Meanwhile, I did some poking around and I found a gen~ versionof the rampsmooth~ in Max that works exactly how I would expect: History value, prev, stepcounter, increment; input, rampup, rampdown = in1, in2, in3; //input = abs(input); // reset ramp if input has changed, or if ramp parameters change: if (input != prev...
-
Thank you for the advice Julius- that sounds more along the lines of what I was thinking - essentially I am trying to recreate the functionality of the rampsmooth~ object from Max, if you're familiar with that? I am going to keep plugging away at this and see what I can achieve. Seems like a good way to get to know Faust. I'll report any discoveries here- wishing you well- Mark-David
-
Conceptually, the slew of a square wave is an impulse train (alternating signs). Merely clipping that impulse train does not widen the transition interval, and only limits the amplitude. You could introduce an FIR filter (impulse response constant over the duration of the slew interval) to convert each impulse into a square pulse, which would integrate to give the shape you're looking for. However, this is still an approximation to slew limiting in op-amps and such. For more accuracy, the width of...
-
Thank you Stéphane and Julius for your quick responses- For some reason I was having some issues getting the results I wanted with the examples you sent and landed on this: slewRateLim(x,mc) = //x-x':max(-mc,min(mc)):+~x';/// //x-x': max(-mc) : min(mc):+~x'; x - x': max(-0.99,min(0.99)): + ~(-x'*mc); process = os.square(1) <: slewRateLim(_,0.99); Which doesn't produce what I want either. Perhaps there is something wrong with the algorithm I referencing, or I am missing something. It feels like I...
-
Yes, you need to integrate delta after limiting it and before adding it back in, something like process(x) = x - x' : max(-maxchange,min(maxchange)) : +~*(0.99); where I chose 0.99 in place of 1 (or +~_) to use a "leaky" integrator instead of one that could drift away at dc. This is a discrete approximation to "differentiate : clip : integrate" Julius On Sat, Sep 12, 2020 at 12:11 AM Stephane Letz letz@users.sourceforge.net wrote: Welcome Mark-David !

Welcome Mark-David ! You’ll have to use the « Recursive Composition » operator (AKA : tilde ~ character) to express computation on a signal and its past state. Look at the syntax documentation here: https://faustdoc.grame.fr/manual/syntax/ So in your example: limiter(maxchange) = (- : max(-maxchange) : min(maxchange)) ~ _; R = 0.5; process = limiter(R); The generated C++ code for the DSP loop is then: virtual void compute(int count, FAUSTFLOAT inputs, FAUSTFLOAT outputs) { FAUSTFLOAT input0 = inputs[0];...

Hello, Is there any library that analyses in real time the frequency of an audio input, with low latency ? I have already made a prototype with a teensy board that works OK (see the link), but I wonder if I could get a faster response with a faust implementation. My prototype uses the YIN algorithm. I have also tried FFT, but it gives wrong estimations due to the partial harmonics of certain instruments. Thanks for any help or ideas. Emmanuel https://www.youtube.com/watch?v=N79Hcg-cOfI

If the Problem still exists anymore, this way works fine. I had the Midi Problem on Juce in VST Instruments, and with this Way in the Meta Description it works exactly the same like in Audiounits it works fine. If you declare it in the DSP file it set this Metas not automatic in the Class, and is not documented in the Faust Manuals, but it works consistent on all regular Hosts i tested on Win, Linux and Mac. m->declare("options", "[midi:start]"); m->declare("options", "[nvoices:16]");

The natural "array" in Faust is a bank of signals in parallel. On Fri, Feb 7, 2020 at 6:14 AM John Lynch saxtonhale@users.sourceforge.net wrote: Thanks for the stuff to look at.

Hi John, First part of the answer: what is your use case? Second part: look at the « waveform » and « table » primitives in the manual and documentation here: https://faust.grame.fr/doc/manual/index.html#waveform-primitive https://faust.grame.fr/doc/manual/index.html#table-primitives https://github.com/grame-cncm/faust/blob/master-dev/documentation/faust-quick-reference.pdf Stéphane Le 7 févr. 2020 à 06:08, John Lynch saxtonhale@users.sourceforge.net a écrit : I've seen one or two references to it...

I've seen one or two references to it in the manuals, but nothing besides that. Are there ways to create and utilize arrays in a Faust program, as opposed to writing out each and every piece of data to separate variables?

I'm working on a personal project where I'm trying to extend the faust playground to be able to drive faust instruments with midi files. I'm curious if anyone has some insight or advice regarding how to modify a faust instrument's parameters from within the web audio graph. My current solution is relying on callbacks from the main script to set module parameters which is alright for testing purposes, but I'm sure as the project becomes more complex significant timing issues will arise. I feel like...
