Are there any gridflow binaries for Mac OS X out there?

how to create a lowpass filter from first principles?
by Geoff 27 Jan '09

27 Jan '09

Hi I am new to Pure Data, I downloaded and have played around with it for the last couple of days and it is rather wonderful. I can quite happily create a basic synth inside it without too much strife. :) However The reason I wanted to use Pure Data was to implement some of the maths that I am learning through a couple of DSP books that I am studying. The DSP book I have read gives a simple lowpass filter function as g(n) = (f(n-1) + f(n) + f(n+1))/3 i.e the average value of three consecutive samples. I understand how this is in effect a lowpass filter. How do I implement that in PD? I can easily connect a Oscillator (phasor) object to a lowpass filter object to the DAC and hear it working, However I want to be able to create my own lowpass filter i.e. try to really understand how things are put together. Therefore if in the function above I need 3 consecutive samples, I would have thought that I need some kind of buffer to hold and call those samples from, so that I can then call three samples average them and then output that, however that would have to move at the same rate/freq as the audio engine is set up i.e. 44100Hz ..... errrr. So I am thinking about how to solve the problem I just seem to be missing how to start. Any guidance appreciated. geoff

call for DIO error image
by Hans-Christoph Steiner 27 Jan '09

27 Jan '09

I just had a thought: it would be cool if the DIO error button in the Pd window was some kind of indicator light. Tcl/Tk can easily use images as an indicator. Anyone want to try designing a indicator light with on and off states for this? Then I can include it in pd- devel. I was thinking something like a big red warning light, but I am open to anything at this point. .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.

pd in quiet mode?
by Nicolas Montgermont 27 Jan '09

27 Jan '09

Hello list, I was wondering if there are any possibilities to run pd in quiet mode? By quiet, I mean there are no output at all in the pd console (or in the terminal with -stderr). It would be very useful to save CPU power when errors are known and often printed. Any hints appreciated, Greetings, Nicolas -- http://nim.on.free.fr

Outlet on 'struct' object
by Mike McGonagle 27 Jan '09

27 Jan '09

Hello, I was just curious, and looking at the source was not all that obvious, but does anyone know what the outlet on a 'struct' object is used for?

Question on [struct]'s
by Mike McGonagle 27 Jan '09

27 Jan '09

Hello all, I am working on some stuff with structs, and was wondering about the types of data that can be stored in a struct. From the documentation, it appears that you can have fields in the struct that are for 'symbol's, except that when I tried to use them, it gave me an error something like "float expected"... does this mean that struct's can't have symbols in them? Also, have lists been implemented? I have not tried to work with them, but I figured that I could kill two birds with one question (well, actually two, but who's counting...)...

Announce: pdstring v0.08 + locale v0.01
by Bryan Jurish 27 Jan '09

27 Jan '09

morning all, As of yesterday, a new version of [pdstring] is available on SVN and from me (http://www.ling.uni-potsdam.de/~moocow/projects/pd). Following the discussion ensuing from my recent "request for objections", I weaseled some wide-character support into the [pdstring] representation with new objects ([bytes2wchars], [wchars2bytes]) and abstractions ([any2wchars], [wchars2any]). The old [any2string] and [string2any] are now [any2bytes] and [bytes2any], with the old names still working as aliases. In order for the wide character support to do anything useful, you'll need to call setlocale(LC_CTYPE,...) to determine how byte strings are to be interpreted. For this, I've written a quick & dirty external [locale], which has stunning potential for disaster (see the help file for one scenario), but does what it should. I'm still toying with Miller's suggestion of array-based persistent strings, but I haven't found a good solution yet: either we access and re-interpret g_array's data vector (safe at runtime, but gets mangled on save & reload), or we're limited to 24-bit values which t_float can losslessly encode. The latter is more compatible with other pd tools ([tabread], [tabwrite], zexy's [tabset], [tabdump]), but the former would make wrapping C functions a lot more comfortable... ideas, anyone? marmosets, Bryan -- Bryan Jurish "There is *always* one more bug." jurish(a)ling.uni-potsdam.de -Lubarsky's Law of Cybernetic Entomology
