Re: [PD] [PD-dev] What goes on during dsp ticks?

Hi, Charles,
I think it is just the matter of WHERE the code goes.
My understanding (as for now) is that the method registered with
gensym(dsp) is called,
anytime when either the block size or sample rate changes or when the
signal graph is rebuilt.
so that running this check,
if (x-n != n)
x-is_new_or_resized=1;
may be redundant if it is in the DSP chain (typically
classname_tilde_perform) compared to including it in the call back
function. (typically classname_tilder_dsp).
ok, I get it now. cool
There's the dsp routine and the perform routine separately. Makes a
lot of sense to me, now.
Someone please correct me if I am wrong.

That's definitely bad practice.
Instead of that you can do the allocation in the dsp callback, that's
where you add your dsp processing to the signal chain. This callback will be
called anytime when either the block size or sample rate changes or when the
signal graph is rebuilt.
What is the dsp callback? This is new to me, too.
I had a different approach when it comes to building static arrays
that depend on block size. I used three variables in the struct,
x-n, x-array_pointer, and x-is_new_or_resized
Then, example use in perform routine:
if (x-n != n)
x-is_new_or_resized=1;
if (x-is_new_or_resized)
{
x-is_new_or_resized=0;
if (x-array_pointer != NULL)
free(x-array_pointer);
malloc(x-array_pointer, n);
x-n=n;
}
So, you can see the problem. It would be useful to know another way.

be wrong). at least with tabread4~, the 1st derivative is not continuous, while it should be with a cubic interpolation. The Lagrange interpolation scheme is not continuous, because it fits a polynomial through 4 points (-1, 0 ,1 , 2) and interpolates between 0 and 1. But when it goes to the next 4 points (0, 1, 2, 3), it fits another polynomial and interpolates between 1 and 2. So, the discontinuity in 1st derivative is at each sample. i program a cubic interpolation, and the shape of the waveform is really different. please compile the object and look at the help patch to see the difference. i can also send waveforme picture if needed. I'm having trouble compiling, due to the garray_getfloatwords symbol. Which version of Pd are you using? I'd like to see the waveform and test it out. Here's my analysis of key points (a=x[-1], b=x[0], c=x[1], d=x[2]) 83 a0 = d - c - a + b; 84 a1 = a - b - a0; 85 a2 = c - a; 86 *out++ = ((a0*frac+a1)*frac+a2)*frac+b; At frac=0, output should be b. Check! At frac=1, output should be c ((a0*1+a1)*1+a2)*1+b =a0+a1+a2+b =d-c-a+b + a-b-(d-c-a+b) + c-a + b =d-c-a+b + a-b-d+c+a-b + c-a + b =d-c-a+b + 2a-2b+c-d + c-a + b =c Check! 1st derivatives: At frac=0, d/dx f(x) = c-a (This quantity really ought to be (c-a)/2, but let's see how the rest comes out) At frac=1, d/dx f(x) = 3*(d-c-a+b) + 2*(a-b-d+c+a-b) + c-a =d-b So, we've got 1st derivatives that match between samples. Check! This looks like a really good plan. I might suggest some new coefficients to try: a0=(3b-a-3c+d)/2 a1=a-5b/2+2c-d/2 a2=(c-a)/2 The only difference is the 1st derivatives are (c-a)/2 and (d-b)/2, respectively. Maybe you could try a 5th-degree polynomial next and set the 2nd derivatives for continuity. This would involve 4-points as before, but it might introduce a ripple in the interpolation (cubic interpolation can't do that, since it only has two critical points). I'm not keen on doing the spectral analysis, because it would take about 4 hours, to do it by hand. There's something I would like to see (once I can compile it). I made a patch (attached) a while back to view the tabread4~ interpolation function (impulse response). Give it a try if you're inclined to do so, because it might surprise you.

Re: [PD] Teaching Pd to Children
Thanks so much for your comments everybody! I am still mulling over it, but I like the idea of using something like Squeak as well. I remember using a DSP software last year that was very children-oriented, but cannot for the life of me remember the name of the software or where to get it! As for Pd, I will be scouring for more resources. I'm thinking that fun is more important than math. After all, this IS summer school. As for what K-8 summer school is: K-8 is an age range from 5 years old (K, Kindergarden) to 13 years old (8, 8th grade). Summer school is an extra time for kids to catch up on learning when everyone else is on break in the US. Also, thanks Andy for providing such a wonderful resource! It's grown quite a bit since I first laid eyes on it. ~Kyle On Sat, Jun 14, 2008 at 4:27 PM, Peter Plessas [EMAIL PROTECTED] wrote: Kyle Klipowicz wrote: Hello Listers~ I'm teaching a 1 month Summer school session for K-8 grade students and would like to include Pd for a mathematics learning tool. I am wondering if anyone else has done something similar, or has any links to DSP/math related materials that would be suitable for this age group. Also, if anyone is sharing their lesson plans for Pd beginners, I would love to see something that I might be able to adapt for my students. Any ideas would be greatly appreciated, as kids often hate Summer school and I want to make this a fun activity for them. Make sure to tackle number ranges (mapping), like: Moving one slider up will make another one go down, but only half as far, etc... ~Kyle ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list -- - - - -- http://perhapsidid.wordpress.com http://myspace.com/kyleklipowicz ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Maybe I'm growing old but differerences in interpolation methods are very subtle to my perception. What would be the hard case to test it? It would be when the signal is greatly transposed, right? Remember when I tested your stab at sinc interpolation Charles, I honestly couldn't hear an big difference, there was one, but hard to define. yo, i recorded a snare drum sound (from the netpd-patch bon-minidrm) into a table and made a comparison, while playing the sample at different speeds. i chose the snare, because it has lots of noise in the high frequencies and i assume, this will probably rather make any interpolation effects audible. when playing at 0.05x original speed, the differences between [tabread4~] and [tabread4c~] are not so subtle anymore. [tabread4~] sounds almost 'gameboyish' compared to [tabread4c~]. without any scientific approach and without any judgement about which of those two methods gives the result, that comes closer to the imaginary function of the original soundfile, it's becoming obvious, that cubic interpolation sounds more what one would expect from an audio interpolation algorithm (i.e. less audible artefacts). the difference is not only clearly visible, but also audible, especially when transposing very low downwards. i couldn't hear any difference, when transposing upwards, though. roman ___ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] USB Port ID
Hi folks Greetings from Buenos Aires, I've just become a member of the list. My first post is a question: does anyone know a way to recieve from 2 different alphanumerical keyboards their USB Port ID besides their ASCII codes? I need both keyboards for a project, but they both send the same codes; any other ideas for splitting this information? Thanks in advance!

[PD] Idea for contextual menus
Yo, I just added an idea to http://puredata.info/dev/GuiIdeas and thought I'd post it here too for discussion, since one day I may get around to doing it (or perhaps someone else with more pd-hacking talent wants to :) ) An object, [contextitem 1 Change colors...] would add a Change colors... item to either the current canvas, the parent of the object (when the object was right clicked), or both depending on the first argument (0, 1, or 2 respectively). The remaining arguments would specify the name of the context item (to allow for spaces), and the [contextitem] object would have a single outlet which would [bang( when the context item was clicked. This (combined with a state-saving solution) would allow emulation of Properties dialogs, and would be generally useful for embedding functionality in tight spaces.
