Subject: [chuck-users] Filters and filter education<br>
<br></div><div class="HOEnZb"><div class="h5">
I've been periodically fussing over trying to construct a phaser (the<br>
effect, not the fictional weapon) and while there's a working ChucKian<br>
example at <a href="http://electro-music.com/forum/viewtopic.php?t=23264" target="_blank">http://electro-music.com/<u></u>forum/viewtopic.php?t=23264</a> , I'd<br>
like to understand more about what's going on.<br>
<br>
The example uses a PoleZero filter, which may as well be called<br>
PixieWand for all I know what it actually does. There are numerous<br>
other filter UGens as well; I think there may be a whole world of<br>
filtration out there I can't even imagine.<br>
<br>
The ChucK documentation doesn't provide descriptions of the mechanics<br>
of these filters. I get the impression that they're things you're<br>
expected to understand if you have a formal background in DSP, and if<br>
you don't, well, it's a bit of a leap to get there.<br>
<br>
For now I'm optimistic I can get educated in some way. A 2006 post on<br>
this subject on this list<br>
(<a href="https://lists.cs.princeton.edu/pipermail/chuck-users/2006-June/000763.html" target="_blank">https://lists.cs.princeton.<u></u>edu/pipermail/chuck-users/<u></u>2006-June/000763.html</a>)<br>
suggested reading Real Sound Synthesis for Interactive Applications<br>
(<a href="http://www.amazon.com/Real-Sound-Synthesis-Interactive-Applications/dp/1568811683" target="_blank">http://www.amazon.com/Real-<u></u>Sound-Synthesis-Interactive-<u></u>Applications/dp/1568811683</a>)<br>
by Perry R. Cook.<br>
<br>
The book looks promising, but I'm not sure if it tackles the subject<br>
to a depth that would be helpful. Has anyone read it and could<br>
recommend? Perry, what do you reckon? =D<br>
<br>
Many thanks,<br>
<br>
