by Mustafa Umut Sarac 27 Feb '07

27 Feb '07

Hello , I want to extract and record 1962 Fender Fretless Jazz Bass from Jaco Pastorius records , I learned from mit digital stradivari project that it is possible to transform music to spectrum peaks and play with them like an EQ. Is it the correct way and how can I do it ? Best , Mustafa Umut Sarac

cpu issues
by marius schebella 27 Feb '07

27 Feb '07

hi, I am running Pd 0.39.2-extended-test7 on a macbookpro. starting pd and doing nothing gives me 18% of cpu load! and another problem is, when I use oggcast~ and osx falls to sleep mode, then later I cannot quit pd anymore. the pd process stays alive and it happened twice to me that after some time, when I did not recognize it, that process was eating up to 150%. anybody have ideas about shutting those leaking wholes? marius.

Dynamic patching questions
by Alexandre Quessy 27 Feb '07

27 Feb '07

Hi, A few questions regarding dynamic patching using only Pd messages (or internals) : 1) Is it possible to delete and disconnect objects without clearing the whole canvas ? 2) Is it ok to create GUI objects with not even half the arguments it could take ? Pd seems to be likely to crash when we create GUI objects using a message with the atom "empty" in it. 3) Is the use of [namecanvas $0] recommended or totally deprecated ? 4) Where can I find an abstraction or object to convert any familiar representation of colors to the Tk colors (or whatever is used for GUI objects) ? Thanks ! -- Alexandre Quessy http://alexandre.quessy.net

Creb and PDP libraries incomplete in 39 extended on MacIntel 10.4.8
by Mark Pasquesi 27 Feb '07

27 Feb '07

Greetings. Below is cut from my PD window: I use - MAc OS 10.4.8, Intel minimac.1.83 duo. I have installed Dev tools, Fink and x11 to help me along the way. I also use a portable g4 (500 Mhz) on OSX10.3.5 to test things on. It has Dev tools and x11 (unfinked at the moment). PDP problem named at opening (Architecture and library for pdp). (pdip example works for communication-pddplink-test). pdp is missing nearly all pdp objects when tested. Creb is missing onecomp object, biquadseries, and ibfft. Hit or miss for object used in examples. Should I compile Creb and pdp independently? Confused if I should do all through terminal or x11, or instead drag and drop after doing a control click inside PD extended to open the package??? or should I just try to compile there?? Thanks /usr/local/lib/pd/pdp_pidip_osx/pdp.pd_darwin: dlopen(/usr/local/lib/pd/pdp_pidip_osx/pdp.pd_darwin, 10): no suitable image found.

this came up not so long ago: just change the canvas sizes in a text editor. cheers, robbert "Chuckk Hubbard" <badmuthahubbard(a)gmail.com> wrote: > The reason it was a huge problem on Mac was that, once the > window is larger than your display, there's no way to get to the > resize button on the lower right corner of the window.

didn't mean to offend. i'm not saying it's not a bug, but it hasn't bothered me too much (my patches don't have that many windows). robbert "Chuckk Hubbard" <badmuthahubbard(a)gmail.com>wrote: > You lost me at "just".

a couple complex number abstractions
by Charles Henry 27 Feb '07

27 Feb '07

Hi, list, I put together a few abstractions I wanted to share. These are just basic operations for complex arithmetic (I left out conjugate, addition, and subtraction, since I thought they were too basic). cmult~ -- multiplies two complex signals; inlets are ordered from left to right: sig1-real, sig1-imaginary, sig2-real, sig2-imaginary (this is consistent for all the rest too) conj_mult~ -- multiplies sig1 by the complex conjugate of sig2 cnorm~ -- computes sqrt(real^2+imag^2), Would this be more efficient using expr? cnormsq~ -- computes real^2+imag^2. Same question as cnorm~ cdiv~ -- divides sig1 by sig2. Wherever sig2 is zero, the result is zero rather than undefined. It is still not advised to use cdiv~ unless you have a signal that you know has all of its frequencies cdiv_thresh~ -- accepts a threshold argument, and divides sig1 by sig2 whenever the complex norm squared of sig2 is greater than the threshold. Returns zero otherwise. Later, Chuck

Green screen with pdp_yqt
by Erwan Lerale 26 Feb '07

26 Feb '07

Ola, I've been using pdp_yqt for a while but now I'm attacked by the green syndrome :) Such issue has been mentioned in the past : http://lists.puredata.info/pipermail/pd-list/2006-03/036027.html Yves was asking for libquicktime version and codec. I'm using libquicktime-0.9.10 and qtinfo says : Type: Quicktime 1 audio tracks. 2 channels, 16 bits, sample rate 44100, length 147008 samples, compressor ima4. Sample format: 16 bit signed. Channel setup: Not available supported. 1 video tracks. 320x240, depth 24 rate 12.000000 [600:50] constant length 40 frames compressor jpeg. Native colormodel: YUV 4:2:0 planar (jpeg) Interlace mode: None (Progressive) supported. (says file used to work before and is still working with pdp_qt) Any ideas ? Anything I can try as pd is not sending any debug output ? Gracias r1
