Re: [PD] [PD-announce] new GUI obect: filterview, for generating and seeing biquad coefficients

[APO33]

Hey Hans
thanks for this one! I was using it in max ten years ago, I am happy  
to be able to use it again in PD, nice shot!
I am testing it now, I tell you if I see something wrong, so far, it's  
all good.


cheers

Announcing [filterview], a new GUI object for generating and  
visualizing biquad coefficients.  It allows to you manipulate the  
filter band, frequency, and gain using your mouse.  The magnatude  
and phase are then graphed in realtime as the parameters changed,  
and the list of biquad coefficients are output. It is inspired by  
the [filtergraph~] object in Max/MSP.  Thanks to Mike Moser-Booth  
for doing all of the math behind the scenes.


It requires Pd-extended 0.43 to run. I just got to a beta state, it  
works well for me, but it does crash Pd sometimes when you close a  
patch with [filterview] in it.  Try it out and let me know how it  
works for you.


http://puredata.info/downloads/filterview

Also, as a side note, this object is an experiment with a new way of  
writing GUI objects.  It started out as a pure Tcl program, and the  
GUI part still runs as a standalone Tcl program (try running  
./filterview.tcl from the Terminal).  This makes development and  
debugging vastly easier.  Additionally, I tried to move more of the  
GUI code to the Tcl side, so you'll see that it uses fewer  
widgetbehaviors, and uses Tk's bind feature quite a bit.

Yeah, I see that on my computer too.  It was working well for me in 
development, I guess I was mostly using ./filterview.tcl...

That actually can be fixed (or at least improved) in line 75:

for {set x [expr int($framex1)]} {$x <= $framex2} {incr x [expr
$framewidth/40]} {

It's only calculating 40 points within however many pixels the width
is. It should probably be incrementing by a constant, with 1 being
every pixel.

Re: [PD] [PD-announce] new GUI obect: filterview, for generating and seeing biquad coefficients

[Mike Moser-Booth]

Thanks, Hans, it's great to see this! Unfortunately, it's not really
working well for me on OSX 10.5. It seems that once I click on it, the
cutoff just follows the mouse around, even after the mouse button is
released. And then eventually the spinning beach ball comes up. (This
is using the Pd-extended 0.43 build from March 23.) When I just run
the tcl script from the terminal, though, it works fine.

Re: [PD] [PD-announce] new GUI obect: filterview, for generating and seeing biquad coefficients

Yeah, I've seen that.  That's really a matter of getting the math right for the 
calculations to draw the lines.  I suck at math so I'll leave that up to 
someone who doesn't.  The math is all in the filterview.tcl file.

Yes, you were being too cryptic ;)  When there is a commit in Gem's 0.93 
branch, I'm happy to commit it to the Pd-extended 0.43 release branch.  Done:

http://pure-data.svn.sourceforge.net/viewvc/pure-data?view=revision&revision=16109

John, tomorrow's will include this fix, if you can test it again.

Re: [PD] [PD-announce] new GUI obect: filterview, for generating and seeing biquad coefficients

[batinste]

I built it for pd-ext 64bits on ubuntu current, it works well (some 
crashes at exit, as you said) !
Is there an easy way to make the magnitude response polygon less 
"polygoney" ? If you move a strong notch filter along the spectrum, you 
can actually see the line acting like a bike chain, thus changing the 
visually perceived response of the filter.

probably i'm a bit too cryptic: Gem's 0.93 git-branch already has the
cherry-picked fixes applied.
so checkout the 0.93 branch, compile and see whether it has the problem

"committed it to Gem's git (committish 1458b4f8cf in the 0.93 branch)"

it would be nice, if john could test it more directly, without having me
fix the bug in Gem's master, then backport it to Gem's 0.93, then having
hans backport the changes to Pd-extended, then wait for the nightly
build and then report that it is not working...

backporting from Gem's master to Gem's 0.93 is fairly trivial using
git's cherry-pick. the rest is less fun and should probably only be done
once the bug is really fixed.
