[Fwd: Re: [PD] hardware recommendation]
by Matthijs van Henten 17 Aug '05

17 Aug '05

I have used a P4 with ddr ram and hyperthreading on linux. I was playing 4 high-quality video sequences of 512x576 and rocking audio. The main bottleneck was harddisk speed! if you need a lot of data I'd use multiple harddisk, or, even better, a motherboard with hardware array. I was using a ati radeon dualhead. You are not using the gpu -- ? matrox g200 is not very fast. The reason for the strange video scale was that I was in fact projecting on 4 screens at the time, splitting the beam in half and using the vertical distortion to stretch the image back again. 0 /\ \/ 0 where o is projector and tnhe \/ was a diamond shaped 'screen' You can also perfectly do with one dualhead graphics card and 2 pci graphics card. Since you're res is so low you could even just use video (?) resolutions and sync convertors? I have been using a tseng labs 6200 and S3Virge cards together w matrox dualhead cards to make a 2x2 videowall from old pc's and tv's ( does the beamer have a sub9 connector ? ) At the time athlon 64 was more expensive then lower class P4 hyperthreading. If you look at the specs, you'll see that giving money for good ddr dual channel ram is more interesting then simple cpu power. Hyperthreading also works great under linux - you have the 'feeling' of a dual processor system. 'normal' Athlon is a lot slower then P4 omho - I'm looking for more then 20% price drop if I see a more then 20 % performance drop and this is not the case. Of course I'm now talking about power you need for video ( either generating or playback?) in high quality. limiting to one pc can save you headaches and might be cheaper at this time - unlike a few years ago when bying a couple of duron's was a good cheap option. that's my 2 cents.

I have rebuilt pd using visual studio, so that I use the same tools as those used for the OSC extra, and I have added the following: #define OSC_API __declspec(dllexport) which should export all the functions (OSC_API is in front of all functions declaration) but I still get the same error: load_object: Symbol "osc_setup" not found osc: can't load library is __declspec(dllexport) enough to export the symbols in the right way? any suggestion is welcome.

24 bit causing distortion
by alexandre matheson 16 Aug '05

16 Aug '05

hello list, I am trying to use writesf~ to record 24/96 sound files but it seems that any bit depth other than 16 is causing distortion. I'm using pd 0.38-3 from Miller's site on a powerbook with os 10.2, and I'm using audacity for playing back the files. In addition I have the same distortion when loading a perfectly fine 24 bit file into an array.

The Issue with 2 or more inlets
by Sebastian Schwerdhoefer 16 Aug '05

16 Aug '05

Hi All, I'm about to learn puredata, but I didn't reach very far. I understood the issue with 2 or more inlets, and read, that a trigger could help - but never found an example for that. I'm not shure if i really understood that trigger thing, so can anyone look at "my" example? Best regards, Sebastian SchwerdhÃ¶fer
