Category: puredata Group: None Status: Open Resolution: None Priority: 5 Submitted By: IOhannes m zmÃ¶lnig (zmoelnig) Assigned to: Miller Puckette (millerpuckette) Summary: resampling method for halfblocks Initial Comment: this patch adds a new pair of up/downsampling methods, called "block". what it does: downsampling: the 1st part of the original signal is copied "as is" to the downsampled signal; the rest of the incoming signal is discarded upsampling: the original signal is copied to the 1st part of the upsampled signal; the rest of the upsampled signal is set to 0.f what for: an the output-signals of an fft are redundant since they are (anti)symmetric; therefore it is a waste of cpu-power to apply dsp-processing on both halfs of such signals; with this patch it is possible to do a "downsampled" processing only on the relevant (1st) part of the signal (~50% performance gain): after upsampling you would have to recreate the entire signal manually (e.g. mirror the block and add it to the non-mirrored part) i also put some defines for the various resampling methods into m_pd.h, so the code gets less "magic" ---------------------------------------------------------------------- Comment By: Mathieu Bouchard (matju) Date: 2006-06-20 14:35 Message: Logged In: YES user_id=801174 to save on CPU and memory, a "doubly real" FFT is possible: not only real inputs, but also real outputs. For a N-dimensional vector (block size N), there are 2N outputs. The way that it is normally reduced back to N, is to combine them to produce cosine and sine coefficients. I wonder whether that'd be a more appropriate way of dealing with the problem than using varying block sizes? (Maybe it's not) Also, what seems to be a clearly interesting use of the "block" method is that if you do [fft~] before a "block"-upsampling and a [ifft~] just after, then you've just done trigonometric interpolation, that is, interpolation that uses sinusoids (instead of cubics and stuff). IMHO this is the best way to upsample a signal *if* block boundaries are properly dealt with (using windowing). However, I've never tried this. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478072&aid=1509427&group_…

Re: rh/ccrma pd-extended rpm

Hmm, can't think of any scripts there that would be specifically helpful to the RedHat packaging. If you haven't seen this stuff already, its probably helpful (in CVS): packages/linux_make packages/redhat_rpm (on the web) http://puredata.org/docs/developer/Debian http://puredata.org/docs/developer/build It would be nice to have a RedHat port of scripts/debian/init.d/pd (it would go nicely in scripts/redhat/init.d/pd). scripts/checkout-developer-layout.sh might make the CVS checkout a little easier for you. .hc On Jun 19, 2006, at 3:31 PM, shift8 wrote: > ok - i'm going through the scripts in scripts/ from cvs, as i never > really used them before. any tips, tricks, undocumented folklore i > should know about? > > On Sat, 2006-06-17 at 12:22 -0400, Hans-Christoph Steiner wrote: >> I am cc'ing the list since I think this is of general interest. >> >> I have talked with Nando about it, his reason for not doing it is >> lack of time.

pd and blender integration?
by glauber alex dias prado 19 Jun '06

19 Jun '06

Hi im new to this list and also new to pd, i am currently translating the pd manual into portuguese (my native language) for others have access to it, i was introduced to pd by Frank BarKnecht trough the linux-audio mailing list and it really amazed me this structure is very ample there isnt near limits with this interface. The fact that im posting to this list is i am a 3d CG artist and my main software to produce images and animations is blender and it has a lack of audio synthesis features. So i thought how good it would be to have pd implemented inside blender so everyone in the "blender" world could be real and complete animations inside of that soft, this is something that i would like to try as an experience to take pd into blender, blender has a node interface that could very well be used to this task though it isnt so mature yet. So i have some questions is this thing that im willing to do "make-able"? If so does someone here has some points where i could begin to do this thing? i was looking for a mentorship thing also but i think that most of you dont have the time now to teach a kid, anyway points and against-points are welcome Cheers Glauber Prado.

spliting pmpd to sigle file
by cyrille henry 18 Jun '06

18 Jun '06

hello, in order to allow a better integration to hsc installer, i just split pmpd in single file. i commited the change, and added the new file to build in external/build/src i did not change the other build system. the only problem i've got is that the old french name (masse / lia ...) does not work anymore. so i had to change somes example in order to remove this old objects name. This will break some patchs... i save the old pmpd lib : http://drpichon.free.fr/pmpd/download/pmpd_0.7_cvs.tar.gz Cyrille
