Hey Hans,<div><br></div><div>Here's an update of filterview. There are now procs for the following filters:</div><div><br></div><div>lowpass</div><div>highpass</div><div>allpass</div><div>bandpass</div><div>resonant</div>
<div>peaking</div><div>highshelf</div><div>lowshelf</div><div><br></div><div>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).</div>
<div><br></div><div>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.</div>

<div><br></div></div><div>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</div>
