There is a lot this object could do, including having a logarithmic scale for frequency (its linear now).

Here are the steps I took: 1) I opened the help patch in the directory with the .pd_darwin binary file. 2) I turned on audio. 3) I selected a high pass filter. 4) I wondered if changing the bandwidth would do anything, so I moved my cursor over one of the red lines that show bandwidth.

Ok, big update, this should work a lot better.
http://puredata.info/downloads/filterview
I changed the formula below to be a fixed resolution of 5 pixels. I was
thinking that this should be generalized into a general biquad~ library, so
with objects like [bandpass] to calculate biquad coefficients. The
calculations could all be written in C as a shared library, then the Tcl code
could use those C functions also, which I think would allow for 1 pixel
resolution. My guess is that doing the math in C would make things noticeably
faster.

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.

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

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.

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

Re: [PD] [PD-announce] new GUI obect: filterview, for generating and seeing biquad coefficients
Hans, This is so exciting. The binary is working here on a MacIntosh 2.8 GHz Intel Core 2 Duo with OS 10.6.8. I thought you might appreciate some quick user feedback. When I click the graphic, it lets me adjust frequency and amplitude, but then my cursor gets stuck to it like mouse up isn't working. Every time I click it adds another red vertical line. A slight bit more documentation would be helpful in the help patch, too, explaining how one can interact with the graph with the mouse. Is it possible to change the bandwidth with the GUI? is there a key combination one can hold?

Hmm, I thought I got rid of that issue with it sticking to the mouse pointer... arg. Can you tell me the steps to reproduce it? I should add more to the help patch. The goal was to make it as self-explanatory as possible. So you can click and move the filter center and gain, and click and drag on the vertical bandwidth lines to control the bandwidth. .hc On Apr 8, 2012, at 4:33 PM, Samuel Burt wrote: Hans, This is so exciting.

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.

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.
