I try to control a filtergraph with a sine wave

But the result is not as smooth as I would like

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

control-with-cycle

Try using filtercoeff~ instead of filtergraph~. It's for filter

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

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...)

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

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?

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

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

oh, well, I posted because I was really in rush

But ok I agree there the result is the same in view of
