I have a user-defined array, one array of bin amplitudes and one array of bin frequencies, both written from the analysis window. The thing is that you need to deal with the amplitudes too. Simply moving the frequency value from one bin to another doesn't work, because each bin can only represent a narrow frequency band. So you need to also move the amplitude content of the bin too.

Hey Jack, if i have a table with 20 index and i iterate 20 times and then i use [mod 20] i dont see how this is gonna work as you explained.

Re: [PD] measuring entropy of a signal?
Hi, Charles, my idea in using shannons entropy is to measure self generated songs. For example if you have a patch that generate sound structures using a generative rules it would be nice to measure that sound structure and use that measurement to evolve the rules that generate that sound structure in order to create more complex structures for example. But how to measure a sound structure using shannons entropy? I was experimenting taking only short pieces of a larger sound , converting each piece into a string and evaluate the shannon entropy of each string. In this case entropy varies with time and what i am interested in are the entropy trayectories. You can plot this trayectories and compare different trayectories from different songs . More complex sound structures should have more complex trayectories , not chaotic , not periodic but more complex . The problem for me is that i need to plot or visualize the entropy trayectories (values) in order to see the complexity of a sound structure. It would be nice to find a way to automate , for example find a way of measure different trayectories algorithmically and that computer can tells automatically which one is more complex. Do you have an idea? I have a question, why do you say it would be meaning less to convert signal into symbols? Other way i was experimenting is using this with video and images, for example converting an image into a array of characters iterating over all the pixels an getting the color of each pixel , then converting those values into characters and then evaluating the shannons entropy of each image. I would like to expand this and use it also for self generated 3d structure, but im still thinking about this. cheers. R. can you please explain me why do you say it would be meaningless? That would do something, but may be meaningless--It would be just one way of converting the signal from real numbers to a discrete set of things/symbols that is easier to calculate. 2013/2/27, Charles Z Henry czhe...@gmail.com: If you took the fft squared magnitude, perfectly noisy data should have a chi-squared distribution in each bin (I think). If you assumed that model and calculated the parameters of the distribution on each block, you'd find out how much information is in each of those peaks relative to the assumed distribution and just add it up. What ever algorithm you choose probably needs to pass some common sense tests like what you mention Martin, noise has more entropy than a sine wave. Also, if you take noise and just apply a comparison 0, you get a signal with less entropy. On Wed, Feb 27, 2013 at 7:54 AM, Martin Peach martin.pe...@sympatico.cawrote: Why not do an FFT and measure the variance of the channels? For instance white noise has maximum entropy and all the bins of its FFT will be more or less the same, while a sine wave has low entropy and one bin will be much larger than the others.

Or perhaps think of it as a rate of information. But for real numbers and continuous distributions, this doesn't work. The information in a single observation diverges. So, doing that with floating point numbers is not practical. You often see Shannon entropy describing digital signals. If the signal just switches between 0 and 1, we can generate a distribution of the data and see what the probability is empirically. The entropy of each new sample is relative to the distribution.

Re: [PD] sending image from of / libpd
i solved this creating a fuction called send inside AppCore:
void AppCore::send(unsigned char *pixels) {
for(int i = 0; i array1.size(); i++)
array1[i] = pixels[i]* 1;
pd.writeArray(array1, array1);
}
then im calling the function from testApp.cpp and sending the pixels
from a opecv gray image.
void testApp::draw() {
core.send(grayImage.getPixels());
}
What do you guys think, maybe theres a more effective way?
cheers

If we converge to a reasonable number, that'll be the new limit. Otherwise,

personally i do think that any fixed limit is going to impose troubles.
afaict, the main idea here is to provide an easy to use API, combined
with some performance.
somebody _will_ reach your hard limit, and i think that telling them to
either switch from the foolproof API to export mode or to redesign
their patches just because they called add_element() once too often
will not do.
why not simply resize the internal array as needed, starting with 32
elements and doubling whenever the limit is reached?

[PD] panning abstraction or object?
Hi list, i was wondering if theres an abstraccion or object like this in pd: I need a pan object that when is -1 is complete silence and when is +1 is complete silence too. when the value begins to move from -1 to +1 the sound begins to appear in the left speaker then it moves to the right and then the amplitude decreases in the right speaker until it arrives to +1. Is there something like this in pd? thanks in advance. R. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] loading sound from pd into csoundapi
Hello everybody, im using csound with pd using csoundapi, Im not really a csound guy so i been mostly experimenting with csound codes made by other, like granular synthesis codes. If i want to send a parameter from pd to csound i just add this line in csound: gk3 invalue grain_size I was wondering how can a do for loading sounds in csound from pd. i would like to have different options like sound1.wav, sound2.wav , sound3.wav. as pd messages and then just select from pd the sound i want to load into csound. Do anybody know can i do this in csound/pd? This is my code in csound with the sound i would like to change from pd: CsScore f1 0 0 1 kukon.aif 0 0 1 f2 0 1025 20 2 1 i1 0 3600 /CsScore thanks in advance Ronni ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] sonyfing chaotic functions
Hello everybody , i was wondering if somebody have worked sonyfing chaotic functions in pd. But not mapping the values from the functions into sound parameters, but instead using the resulting values for generating waveforms. Do anybody have tried something like this in pd? Maybe theres some example patches i could begin studying? thanks in advance R. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] OT: Ir leds
Hello everybody, i dont know if here is the correct place to ask, if anybody know another forum related to this , i will be very happy if somebody can show me: Im making an interactive floor and i need to iluminate a space of 4 x 4 meters with ir light. I been seen there are some ir leds matrix on survillance stores but they are expensive to my budget, so i was thinking that i can build my own ir led matrix . I been seen there are tons of different types of ir leds with different characteristics. Do anybody know which ir leds do i need for this? which model, label or serial number? Any idea would be appreaciated thank you very much Ronny ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] multiblob without luminosity
Hello pd list. I would like to know if its possible or if there is a way to have something like the pix_multiblob object but not based on luminosity but instead on background substraction. I been seen that with opencv it is possible to track blobs based on backgound substraction instead of luminosity. How can i achieve this in puredata? thanks in advance Ronni Montoya Huamani ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
