Pd's oscillator wave tables are 512 samples. Supercollider uses 8192 - not sure what CSound uses. The efficiency of the SC code allows for large sample tables and bigger FFTs, which certainly help make a 'smoother' sound. <br>
<br>It would be interesting to hear what happens with 16x larger tables in Pd.<br><br>PS - Amazing that Andy Moorer replied to the blog about the SC version!<br><br><div class="gmail_quote">On Thu, Mar 25, 2010 at 7:37 PM, Andy Farnell <span dir="ltr"><<a href="mailto:padawan12@obiwannabe.co.uk">padawan12@obiwannabe.co.uk</a>></span> wrote:<br>

Yep I did that as an exercise way back. Lost the code<br>
and wavs now sorry to say :(<br>
<br>
But, yes it did show up the weakness of Pd oscils<br>
when compared to Csound - somewhat muddier, with<br>
a slight distortion when using so many.<br>
<br>
IIRC its a saw/string like wave and I made it<br>
bandlimited by filling tables and felt very<br>
confident it couldn't be aliasing because<br>
I calculated no sweeps put any harmonics even<br>
close to Nyquist. So, he difference tis kinda<br>
to do with the small table size or interpolation<br>
in Pd I think. Of course in Csound it sounds<br>
gorgeous.<br>
