Hello,

I try to control a filtergraph with a sine wave
so I use a cycle~ of course.
But the result is not as smooth as I would like
here is my patch
I'm sure there is a smarter solution
but I don't find it

thank's for the help

best
Eryck

Try using filtercoeff~ instead of filtergraph~. It's for filter
coefficients updated at the signal rate.

very nice !

thank's both of you for the quick responses

(I know it's was a basic question, but just no time
for the moment to read the reference guide...)

Cheers

I just had my first day of classes after almost eight weeks so I am probably
super sensitive to dealing with people who are "too busy" to do what is
required of them. Two people on the list help you and you still tell them
that you were too busy to read the reference?

Nelson's corollary to Murphy's law: If you do something to save yourself
time you almost certainly cost someone else some of their time.

You're welcome, but this is why the "see also" section of the help
files is invaluable for this sort of thing. If you pull up the help
file on filtergraph~, you'll find filtercoeff~ in the list. I would
also suggest that this is a perfect reason to print a copy of the
documentation. If you look up filtergraph~, you'll run into
filtercoeff~ right next to it.

...where that someone else is quite possibly yourself.

oh, well, I posted because I was really in rush
not to save my time.
what is lightly different,
But ok I agree there the result is the same in view of
the Nelson's corollary Murphy's jaws.

peace
