PiDiP v0.6.2 [ color tracking ]
by Yves Degoyon 12 Jan '03

12 Jan '03

hi, again a new release of PiDiP with a new object : pdp_ctrack : color tracker it lets you pick up a color in a frame and then tries to follow the movement of this color in next frames. if the color identifies an object, you can follow the movement of that object in your video. of course, there might be some confusions, collisions, .... it's color based, remember. enjoy!! sevy/yves

ratts: realtime analog text-to-speech
by Bryan Jurish 12 Jan '03

12 Jan '03

Hi all, Anyone who wishes to hear PD speak may wish to check out my new "ratts" library, based on Nick Ing-Simmons' "rsynth-2.0" and Jon Iles' "klatt3.04", and on Travis Newhouse's "mapper", via Orm's "maphash". This library replaces my "klatt~" external (which it now includes), and allows full text-to-speech synthesis within PD without any nasty resampling or shameless cpu-blocking. There are even some rudiments for a potential "singing voice" abstraction. The library probably will not enter CVS until it reaches version 1.0, when I hope to have it using all GPL code; for the moment, there are some lurking question marks. For now, it's available from me at: http://www.ling.uni-potsdam.de/~moocow/projects/pd Tested under linux. Short summary of objects included: EXTERNALS: klatt~ : Klatt cascade-parallel formant speech synthesizer holmes : Holmes/Mattingly/Shearme phonetic interpreter phones2holmes : phone-string to Holmes-element converter guessphones : NRL english to phone-string converter number2text : number to english text converter rattstok : raw text tokenizer toupper : upper-case symbol normalizer rattshash : Auto-resizing hash table rattshread : Auto-resizing hash table reader rattshwrite : Auto-resizing hash table writer ABSTRACTIONS: ratts~ : full text-to-speech abstraction rattsdict : shareable dictionary EXECUTABLE PROGRAMS: mkdicttxt : create a "rattshash"-readable dictionary from a raw text source (beep or cmudict). peace, love, and marmosets, Bryan

syncgrain~ in CVS
by Frank Barknecht 10 Jan '03

10 Jan '03

_ ____syncgrain~ - external for synchronous granular synthesis. syncgrain~ is a port of the SndObj-Object SyncGrain. The original SyncGrain dokumentation by Dr Victor Lazzarini goes like this: The source sound for the grains is obtained by reading a function table containing the samples of the source waveform. The grain generator has full control of frequency (grains/sec), overall amplitude, grain pitch (a sampling increment) and grain size (in millisecs). An extra parameter is the grain pointer speed (or rate), which controls which position the generator will start reading samples in the table for each successive grain. It is measured in fractions of grain size, so a value of 1 will make each successive grain read from where the previous grain should finish. A value of 0.5 will make the next grain start at the midway position from the previous grain start and finish, etc. A value of 0 will make the generator read always from the start of the table. This control gives extra flexibility for creating timescale modifications in the resynthesis. _ ____Changes in the pure-data.sf.net CVS syncgrain~: While the older syncgrain~ loaded wav/riff files into its own memory as grain sources, the current CVS version uses on standard Pd table/array objects instead. This opens up new possibilities, one could think for example of a granulating delay line done with tabwrite~. A bug, that caused a Pd crash if the grain array is deleted was fixed (I hope). A packaged version including linux makefile and binary will soon be available on footils.org, but currently syncgrain~ is CVS only. _ ____Requirements SndObj : SndObj-enabled flext >= 0.4.1 : g++-3.2 prefered, g++-2.9x might work, but is not officially supported :P Destroy sounds, have fun! ciao -- Frank Barknecht _ ______footils.org__

PiDiP version 0.6.1 [ motion detection ]
by Yves Degoyon 09 Jan '03

09 Jan '03

hi, that's now PiDiP v0.6.1, i added the following objects : pdp_mgrid : grid-based motion detection it allows you to trigger some funny things whenever something moves in a region of the captured image )) pdp_o/pdp_i : PD to PD streaming it allows you to send your video processed data to a peer running PD ( linux ), so it's not really streaming, just point-to-point communication. it also requires a huge bandwidth, i'll optimize it soon. + doing an object for MPG4 streaming is not that easy ... enjoy !! sevy/yves

PiDiP v0.6.0 [ my first video object ]
by Yves Degoyon 06 Jan '03

06 Jan '03

hi, i've released a new version of PiDiP, hope you don't mind having to download it every day )) what's new ?? i've added my first video object : pdp_rec, which is a video recorder using quicktime formats. it doesn't ( and will not ) record sound at the same time because synchronisation is really too hard to handle. no, you have to record your sound separately ( using mp3write ?? ) and then merge sound and video using you favorite video software. for those awaiting, next is streaming... 0.6.0 added pdp_rec : a video recording object fixed a bug in pdp_edge incremented PDP release number : it's now 0.6 set proper credits for each effecTV plugin enjoy !! sevy/yves

flext 0.4.1 - library, tutorials and reference
by Thomas Grill 03 Jan '03

03 Jan '03

Hi all, i just uploaded a new release of flext, a c++ layer for cross-platform development of PD and MaxMSP externals. News: - full port for Max/MSP on OSX (which is currently a public beta version) - methods and attributes within class scope (just as it has ever been for native PD and Max) - substantial speedup by hashing for all message, attribute and object lookups - made flext ready for usage as a shared library - portable threading interface for native OS threads and smoother launching of threads via a helper thread - Max/MSP assist functionality (description of inlets/outlets in edit mode) - added a flext class for Synthesis ToolKit (STK) support - much cleaner platform, os, cpu, threading model identification - several simplifications and API cleanups - fixed all known bugs Minor backwards-incompatible changes: - usage of t_classid instead of t_class * argument for class setup functions (no actual change for PD) - flext_base::m_methodmain and flext_base::m_method_ have got const modifiers (rarely used) - virtual function flext_sndobj::NewObjs must return a boolean (relevant only for SndObj classes) There is also a new version of the tutorial with some things fixed and some new examples and also a new version of the reference (aka "documentation"). Download as usual from http://www.parasitaere-kapazitaeten.net/ext best greetings, Thomas
