Hi,
Pretty late but just wanted to add my thanks for this, I will
certainly be making use of it for prototyping. I had actually thought
some time ago to try to develop a JSFX backend myself; unfortunately I
had no idea where to start, so I am glad someone else has undertaken
this labour instead.

But if you're using route, you don't need the next part:

Hi,
Slightly surprisingly, I couldn't find one in the libraries when I had
a look just now, though perhaps it's there under a different name.
However, it's quite easy to define:
clip(rangemin, rangemax) = max(rangemin) : min(rangemax);
min and max are builtin functions which choose the min and

Hi all,
I have generally been a user of FaustLive but have just been looking
at the faust IDE, as I got it running locally for the first time. (I
had always thought of it primarily as a remote/web service up until
now.) I would like to use it as I can see that it's pretty nice;

This should work, but note that it will probably alias somewhat (more
noticeable at high or changing frequencies). The advantage of the
oscillators in oscillators.lib is that they are band-limited so won't
It seems that there isn't one in the standard library.
But the triangle wave in the standard library is made by integrating a
square wave. Analogously, you can construct a var saw by integrating
the pulsetrain oscillator, which is essentially a square wave with

No, this isn't a problem - I have working code which gives different

This is a bit of a limitation of faust for generative-type work.
Faust's no.noise gives part of what one wants from randomness: the
values in its sequence are uncorrelated with each other. However, it
fails to give you the other thing one would want: it is deterministic,
i.e. it gives the same
I am looking at faust's output options for compilation. I have a

from cpp? (Do any of the architecture files included in the

I haven't used the IDE so can't really comment on that. I'm not sure

Hi all,
My filter theory isn't very good; perhaps a filter-savvy faust user
can help me out.
I'm seeking a filter in faust analogous to Ringz in supercollider (
https://doc.sccode.org/Classes/Ringz.html ); that is, a filter whose
impulse response is a sinusoidal oscillation at a given frequency,

Hi Sebastien,
Congratulations on the guide; it looks good.
My French is only so-so, but I would be interested in working on the
translation into English.
I wouldn't want to discourage anyone else who wishes to contribute. If
there are others, we could perhaps discuss dividing the work.
