Re: [PD] help with rfft~

<snip> Does this mean that if frequency and > phase of a sinusoid > can br represented as > A*sin(2*PI*f*t)+B*cos(2*PI*f*t), then the left > output of fft~ is B and the right output is A? Yes, if f is the sample position within the output block (i.e. which frequency it refers to) and t is the frequency of ffting, i.e. block size divided by sample rate. The equations don't have anything about phase, though, as this form represents the input as sin and cos waves (with phase of 0, starting at the beginning of each fft block). > If so, how do I get frequency and phase? I think you mean magnitude and phase. The frequency of the sinusoid depends upon which sample of the output block you are looking at. E.g. if the first three samples output from the left outlet (the cos side) are 0.1, 0.2, 0.3, then the amplitude of the 0*f (direct, 0Hz) component is 0.1, of the 1*f component is 0.2, of 2*f component is 0.3, etc. The 2*f component, for example, will be that which makes 2 complete oscillations within each block. So, sample 2 (counting from 0, i.e. the 'third', counting from 1, sample) of the left output is the amplitude of the cos wave which makes 2 complete oscillations. There's only a direct component for the cos side, as sin of 0 is always 0. You can convert them into magnitude and phase form, where instead of a pair of sin and cos waves of a certain frequency, you have one wave of the same frequency but a certain phase relative to the start of the fft block. Magnitude = sqrt(sincomponentamp^2 + coscomponentamp^2) Can't remember phase, but it should be in here somewhere, together with all of this explained better than I can: http://crca.ucsd.edu/~msp/techniques/latest/book-html/node152.html Good luck, I'm still learning this stuff, but I think it's worthwhile once you get there! ___________________________________________________________ WIN ONE OF THREE YAHOO!

(I cc'ed the list since I think this is of general interest) I've found so far that finding the right HOWTO has been key, I am wondering whether you know of one. Good docs for MinGW have been elusive, and there are quite a few little details that are hard to track down, like when to use MinGW make, and when to use Cygwin make. Here's what I have found so far about setting up MinGW for working with Pd: http://puredata.org/docs/developer/win .hc ________________________________________________________________________ ____ http://at.or.at/hans/

Re: missing libs in Windows Pd-extended

(I cc'ed the list since is probably of general interest) These are compiled as individual objects, no libs needed: iemlib, zexy, mjLib, maxlib, motex, ext13 These are compiled as a "libdir", so with the current Windows builds, you have to add them to the path like this: -lib c:/progra~1/pd/extra/LIBNAME where LIBNAME = one of the names below: creb (abstractions), cyclone, iemabs, iemmatrix, memento, rradical, pixeltango, toxy, unauthorized, zexy (abstractions), (and soon smlib) This should be included in the latest: vasp and Percolate has a non-free license, so it can't be included. .hc On Nov 28, 2005, at 4:46 PM, Ed Kelly wrote: > Hey Hans, > > I decided to start with the Windows version - there's quite a few > libs missing still I see (iemlib, zexy, vasp, mjLib, maxlib, cyclone, > motex, percolate, ext13...) but I'm attempting to compile my externs > under Windows so I'll mail them to you as soon as I'm done sorting out > makefiles &c.

pd setup on G5 + Digi 002
by João Miguel Pais 29 Nov '05

29 Nov '05

Hello, we're trying to set up a system for a concert, which is happening on next Tuesday (very tight schedule). The system is G5, osX 10.4 (dual 2.7G), Digi 002 firewire (it works, was tested with max-msp), running PD official 0.39-1. I'm a bit confused, because I can't find any definitive documentation about OsX. I mean, in the manual the startup flags are clearly defined for windows and linux, but I don't know exactly what to write on the G5. Until now (besides loading libraries) we wrote the parameters -audiodev 2 , which selects the Digi as the audio interface (the other one is the standard Mac soundcard). Funnily -channels 8 didn't do nothing, they remained at 2. But then on the audio test patch it isn't possible to get any sound. On a tryout basis we went through -asio and -pa, but nothing changed. So I guess pd can identify the card, but it doesn't communicate with it. And as I can't find a complete list of osX flags, I don't know which might be missing. Has anyone any exprience with this environment? We're starting to sweat, since the concert is in a few days and it's proving to be harder to make pd work.

Re: [PD] laptop linux
by Ed Kelly 29 Nov '05

29 Nov '05

Hi all, Just an update - Gentoo, Ubuntu, Knoppix, Debian, none will even boot from the installation CDs. Demudi cannot find the network, screen or graphics card. The Intel driver for the graphics chip deosn't install properly on FC3. I have run out of patience, but if I sell it now I can buy something nice. Don't buy an Acer Aspire 1691WLMi laptop, if you value your time and money!

Pd-extended Build System is ready for the public
by Hans-Christoph Steiner 28 Nov '05

28 Nov '05

Its mostly done and now, you can type "make install" and get basically all of abstractions, doc, extensions, externals, pd, etc. build and installed into one directory. With Mac OS X and Windows, you can then package it up with one more step. It would be good to get some There is even some documentation: http://puredata.org/docs/developer/build There is also some useful stuff here, like how to build on various platforms: http://puredata.org/docs/developer .hc ________________________________________________________________________ ____ "I have the audacity to believe that peoples everywhere can have three meals a day for their bodies, education and culture for their minds, and dignity, equality and freedom for their spirits." - Martin Luther King, Jr.

cables on top?
by João Miguel Pais 28 Nov '05

28 Nov '05

hi, If my memory doesn't fail in the "good old times" (that is, before version 0.39) a canvas created after a group of objects would cover everything, including their connections. I just noticed that while creating a patch it is still so, but after saved and opened, the cables appear before the canvases (which doesn't necessarily looks bad, but if you're into tcl/tk semi-modern art). Was this behaviour changed, or it slipped between something? I think it's more logical that when one gui object covers other objects should also cover its connections. joao -- Lugostr. 14 79100 Freiburg i. Br. Deutschland +49 (0)761 7074997 jmmmp(a)arcor.de

Canvas editor patch 2
by João Miguel Pais 28 Nov '05

28 Nov '05

Here is a second (and full?) version of the abstraction to make editing of gui objects much easier and quicker (for those who work a lot with them). Just put them in your externals folder. As I said before, this example is for a canvas, but I'll take the model and adapt it to all other GUI objects. Please try it out, correct, criticise, etc. (even the english, if you want). If it's fine I think I can start the adaptations to the other ones. Some operations might be made not with the most fast sollutions, but I was using only the standard objects of pd. It's not impossible, and it will provide compatibility. Greetings, JoÃ£o Miguel Pais -- Lugostr. 14 79100 Freiburg i. Br. Deutschland +49 (0)761 7074997 jmmmp(a)arcor.de
