Very cool. Works for me, now.
Strangely within the help patch my cursor is always the arrow, and doesn't change to the hand when I'm in Edit Mode, and doesn't highlight when the cursor is over inlets/outlets.

Ok, I pushed updates to the git repo so it should now run using Pd older than 0.43. .hc On Feb 17, 2011, at 12:53 PM, Mike Moser-Booth wrote:
Awesome! I would like to be able to see the phase response, but since most of the time the user is only interested in the magnitude response, I think it should be something you can switch to with a message. .mmb

Ok, I got it working in a limited way as a Pd object and I was controlling my first filter against noise! Good fun. You can still run the .tcl file as a standalone GUI for dev work. Get it from my git: https://github.com/pd-projects/filterview It would be quite nice if the phase was drawn as a thin line over the magnatude graph. What do you think? .hc

Hey Hans, Here's an update of filterview. There are now procs for the following filters: lowpass highpass allpass bandpass resonant peaking highshelf lowshelf I've added some lines to show the phase response (you have to comment out line 135 and uncomment 136 to see it). I also adjust the bandwidth calculations so the handles sit where they should (i.e. -3dB for bandpass/notch/etc., 1/2 power for peaking/shelf). btw, the frequency axis is log-scaled, though it could probably be improved a little. I sort of took a Pd approach to it by making an mtof proc, so the x-axis gets scaled to linear midi notes and converted to log-frequencies. :-) There might be a simpler way to do it. It also doesn't go all the way down to 0 Hz, because doing that with this approach causes the lowest frequencies to take up too much of the graph. I think Max gets around it by using a more compressed scale below 1-2 Hz. .mmb On Thu, Feb 10, 2011 at 12:39 AM, Mike Moser-Booth mmoserbooth@gmail.com wrote:
Sure, I can throw the others together. Now that one is done the rest should fall into place pretty easily. It might take me a couple of days to get to it, though. .mmb

That's awesome, thanks! I committed it under your name: https://github.com/pd-projects/filterview I'd like to implement all of the relevant filters, which algorithms should I use? Or even better, perhaps you want to take a crack at it while I figure out how to display the x/frequency on a log scale :-D .hc
