[PD] Trying to track a ghost pdtk_canvas_getscroll call
Hi all,
I have a real pickle in trying to debug Pd. Namely, when I grep-ed every
single instance of pdtk_canvas_getscroll and commented it out, it still
gets invoked somehow and I am at a loss how. I know it occurs as many
times as there are objects selected that have been moved (so it is
definitely per-object)
The only thing I managed to isolate so far is the following code:
g_editor.c
void gobj_displace(t_gobj *x, t_glist *glist, int dx, int dy)
{
if (x-g_pd-c_wb x-g_pd-c_wb-w_displacefn)
(*x-g_pd-c_wb-w_displacefn)(x, glist, dx, dy);
}
I am however unable to decipher what function is exactly being called by
(*x-g_pd-c_wb-w_displacefn). I only found in g_canvas.h definition of
w_displacefn as part of _widgetbehavior struct but nowhere (except in
iemgui objects) is it linked to anything I can actually understand.
Where does this struct get initialized?
Any help on this one would be most appreciated as that will put a stop
on me pulling my hairs out :-)
Best wishes,
Ico

Re: [PD] The (not) doppler distortion (was: overdriven speaker)
On Wed, 17 Nov 2010, Martin Schied wrote: did you speak about the doppler distortion? true doppler distortion is harmonic for a single sine wave, but not for 2 or more sines of different frequencies. Then can you explain what's wrong in my reasoning ? (the formulas I wrote) It assumes the signal is periodic (even if the period is long ; harmonics are relative to that period, and not the period of either sine wave) Suppose you have two sine waves of frequencies a,b related by a common base frequency gcd(a,b)... what are the frequencies of the non-harmonics ? I'm talking about something detectable. It's the same effect known as frequency modulation, in this case a signal being its own carrier. When a signal is its own carrier, you are below a certain threshold of detectability of frequency change. It's one of the uncertainty principles (closely related to Heisenberg's). When you do FM with a true carrier, the carrier has to be a lot higher in frequency, and that decides how much data you can carry with the carrier. That's the difference between actual FM transmission, and something that's only using the same formula as FM. The difficulty in prediction of a spectrum is that the carrier is an always changing mix of frequencies and not a single sine wave like for a radio station transmitter or in the most simplest case of frequency modulation synthesizers, but it is pretty easy to find out it is non harmonic by listening... non-harmonic related to what ? Well, if you tried it with an [osc~ 200] and an [osc~ 1000], for example, you'd see that by increasing the intensity of the effect gradually from 0, harmonics come up and down, and at first they are multiple of 200 Hz, but for some reason, for very high values, there are other multiples of 100 Hz that appear. I'm missing something because gcd(200,1000)=200, not 100, but at least the harmonics aren't completely weird. I want to add that the vd~ approach is not the perfect implementation for the above described frequency modulatuon. the carrier is delayed against the modulating signal a bit. You can add another [vd~] or [delread~] to fix that. I think I did that in some other version of haut-parleur-doppler.pd, and if not, I did similar things with other effects. Like this it simulates a moving listener instead a moving sound source. But there is no difference between a moving listener and a moving source, apart from the wind. What you mean is, regardless of whether it happens in the listener or the source, the motion is out of phase with the actual signal. Also for a single sine wave the change of the spectrum differs by variation of the delay. Yes, and for several sine waves too. But I think that it doesn't change the nature of the beast very much. A more close to reality simulation which does only fm without delay requires a variable (interpolating?) write into the delayline. Why would you need to do it on write, instead of on read ? Unfortunately I don't know of such externals already existing. However I don't expect the effects being very different from the vd~ method. What if they aren't _any_ different ? A slow 20Hz sinewave modulating some high frequencies will not sound very different if the 20Hz is delayed or not. A 20 hz sound will have a duration which is much longer that the delay. But it depends on the gain you choose. Suppose you have a weapons-grade giant speaker, with a membrane of a few hectares... I mean, play with the [*~] and you can get the delay variation to be bigger than the period of a sinewave. ___ | Mathieu Bouchard tél: +1.514.383.3801 Villeray, Montréal, QC___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
