Kinect Hacking at the last NYC Pd Patching Circle
by Hans-Christoph Steiner 29 Mar '11

29 Mar '11

William Brent was coming to town this month so we moved it a little later in the month to Sunday, March 27. A few of us had Kinect cameras so we explored the new [pix_kinect] to get the depth camera, then used the OSCeleton stuff to build an instrument. In this video you can see William's patch in action with Ralf from Amsterdam as the performer. http://vimeo.com/21627710 .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.

Hey, I'm trying to send some msd data over [netsend] using two instances of Pd on the same machine. I keep getting: 'netsend blocked n msec' messages Should I persevere or get into OSC now? Cheers, Jb

Echo-effect
by Stefan Magnusson 28 Mar '11

28 Mar '11

Hi! Im currently working with a project developing tactile feedback for stimulation of disabled children. Im getting quite far in using a rough surface, a contact microphone and buttshaker. My signal path is something like mic->bandpass->filering->amplitude control of an oscillator->lowpass->speaker i wish to get the sound a bit more interesting, so i would like to add an echoeffect something like: -Starts when there has been no sound (amplitude=0 after filtering) for 0,8 seconds. -Playbacks the last 1,6 seconds of sound (then there will be 0,8 seconds of noise and 0,8 seconds of silence) with 60% amplitude -Repeat the echo with decreasing amplitude (i.e 45, 30 and 0%) I believe i should use delay lines but i have a hard time controlling them the way i want. Some help would be really appreciated by me and the children /Stefan

Re: [PD] pd latency on puredyne 9.10 with Nvidia HDA
by Billy Stiltner 28 Mar '11

28 Mar '11

I actually tried a smaller patch on both ubuntu studio 10.10 as well as puredyne 9.10. On both systems the audio was flawless using a 6ms buffer in pd. So there is nothing wrong with my audio setup. But still the larger patch that runs fine on windows with 50ms buffer will not run without glitching with jack on either linux system. There is a difference in gem's default video codec between linux and windows. However I have tried the patch without even loading gem. What else could be the difference between linux and windows with pd?

Re: [PD] [PD-dev] integrating pdlua into Pd-extended

Hi, I also tried with matju to link gem.dll, with no successfull results, apparently it depends on characters surounding function names we get with pexport, maybe you will have better result with liblua.dll http://www.stats.uwo.ca/faculty/murdoch/software/compilingDLLs/existingDLL.… ----- "Hans-Christoph Steiner" <hans(a)at.or.at> a écrit : > Hmm, turns out it was already installed on the Windows build machine, > > but I just updated it.

Re: [PD] pd latency on puredyne 9.10 with Nvidia HDA
by Billy Stiltner 27 Mar '11

Charles, Do you mean from a terminal startup pd and jack with sudo or to actually log on to the system as root from startup? I don't know how to do that besides running the recovery startup. Linux has changed in the last 15 years. I did try changing the runlevel of the timers and sound card IRQ as well as adding myself to the sound group on another installation and still had the same problem. Bernard, I guess I should have said performance is better on vista than puredyne with said latency settings. I did not actually measure latency. The audio does not drop out with latency set at 50ms on vista but does with puredyne. 2.6.31-9-rt is the kernel i'm using. Yes 50ms is bad for rt performance that is why I'm trying to get this working with linux. It is impossible it seems with vista to get the latency any lower. It is crazy 10 years ago latency was not an issue with 10 times slower machines. The current processor is an AMD Sempron LE 1250 at 2.2GHz. Thanks and Thanks
