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.

Did you see the phase line in the current implementation? I think its
nice to have it there all the time, as long as its not dominant. I
think having the phase line there will remind people that the effects
of filters are never as simple as removing selected frequencies.

Ok, I pushed updates to the git repo so it should now run using Pd
older than 0.43.

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.

Hey Hans,
Here's an update of filterview. There are now procs for the following
filters:
lowpass
highpass
allpass

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

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

I don't know if this is what you're asking, but iirc it's really just
a matter of substituting exp(j*2*pi*fc/Fs) for z in the transfer

Sorry, sent that a little too quickly. I should've also mentioned that
fc=cutoff frequency and Fs=sample rate. And the magnitude of the
result will give the magnitude frequency response and the angle will
give the phase response.
