dear list,
who managed to run pd with less than 30 msec of latency? how do you do that?
i tried: osx on a g3 pismo (~500MHz) osx on a g3 pismo (~500MHz) using an rme/hdsp win2k on a P4 2.5GHz using asio and an rme/hdsp and nothing less than 30msec!
thanks for any replies!

hi juha, list...
i tried in vain to apply Framestein's example patch "drag and drop" onto a normal pd-patch (to load audio files via drag and drop). the problem was that after copy-pasting the framestein objects into my pd-patch, the frames were not dockable anymore.
(the same goes of course for the vice-cersa-process, i.e. to copy paste the audio stuff into the "drag and drop" example patch of framestein.)
i also didn't succeed in creating multiple "framed" objects that would work in docking mode. after closing and reopening they just appear outside the patcher-window and don't accept the "dock xyz" command anymore.
am i doing something wrong ? did anybody face similar problems ?
thanx for any hint

Hello
I am currently working on phase vocoders, and I have two questions about the FFT in Pure Data
(1) When I use a [block~ 4096 8],
- the size of the FFT (~ number of analysis frequency bands) is 4096 and the
overlap is 8
- do the parameters of the [block~] object have an influence on the analysis
window size ? I mean, is it possible to use a window size of 1024 samples and an FFT size of 4096 ?
(2) Blackman / Blackman Exact / Blackman-Harris windows
I would like to use this kind of analysis windows, but I don't even know their mathematical formula ; does anyone know how to implement these under Pure Data, in the same way as the Hanning window is already implemented in most example patches ? (or the mathematical formulas at least)
THank you very much
PS : the phase locking vocoder example patch is truly good. Has anyone ported it to Max/MSP ?
You can find a whole family of windowing function Pd objects at

These objects work fine on my computer, but how do you resize the width of the window ? (default seems to be 64 samples)
The window width is set by Pd using the block~ object.

so the analysis window size and the FFT size are the same parameter in Pd ?

Hi Joe,
I think these objects would be even more useful if they had a settable windowsize, then it would be possible to do zero padding.

I assume someone has mentioned Thomas Grill's Vasp already on this thread, as a possible alternative?
