anti-aliasing table read (tabread4a~)
by Charles Henry 21 Mar '07

21 Mar '07

Hi, list, I've finished programming and (preliminarily) testing an external, which is based on tabread4~. For normal speeds the operation is identically tabread4~ , and for higher speeds, the interpolation polynomial is modified to eliminate aliased frequencies. The transition is smooth and not noticable AFAICT. The compilation is straightforward, you need math.h and m_pd.h. The enclosed test patch will allow you to see/hear what it does. March_of_the_sinusoids is a bit exaggerated, but will show you just exactly what happens. This is a preliminary release. It has no major bugs that I know of, but the error trapping on the bounds has not been implemented yet. So don't try accessing things outside of your table yet!!! (and as a general rule, don't try it anyway) plenty of room for improvement...I have some things in mind for it, already, in terms of efficiency and for increasing the stop-band attenuation, if the anti-aliasing is insufficient.

problem with dates on lists.puredata.info
by Kevin McCoy 21 Mar '07

21 Mar '07

Why do so many of the dates on the pd-list archives at lists.puredata.info show up as Mon, Aug 14 2006 in searches? Clicking on them to go to the actual message displays the correct date. Is this an indexing problem? This just started happening a few months ago; is there a fix possible? It's nice to be able to get an idea of when a message was coming from when you search. Thanks, Kevin -- ++++ http://pocketkm.blogspot.com

unfortunately yes. afaik, there are already versions of pd-extended-0.40 available in the nightly autobuilds. note: 0.4 is _not_ the same as 0.40. roman ----- Ursprüngliche Mail ---- Von: Derek Holzer <derek(a)umatic.nl> An: Roman Haefeli <reduzierer(a)yahoo.de> CC: pd-list(a)iem.at Gesendet: Mittwoch, den 21.

Stupid Symbol Processing
by David F. Place 20 Mar '07

20 Mar '07

[symbol pd-experts(, If I try to process (computer) keyboard inputs thus: [keyname] | [route r s p] | | | | .... nothing matches because the output of [keyname] is prepended by "symbol" and I can't figure out how to get rid of it. Sorry in advance for the stupid question. Baffled, David ___________________ (---o-------o-o-o---o-o-o----( David F. Place mailto:d@vidplace.com
