#store and getting pixel data from a movie file
by ALAN BROOKER 26 Aug '11

26 Aug '11

Hi I hope to ask for some tips regarding obtaining values from a loaded image/movie file by using gridflow ? #store gets can get rgb values from a specified pixel position but any advice on getting the whole dimensions at once (or any other techniques in getting gridflow to output values from a movie file such as movement, luminosity or anything)? ...also is there support for mp4 in gridflow? the file format being the same as mov (I think?) Thanks all for any thoughts

Re: [PD] Headphones question on pd list

[...] I'm just talking about things that could potentially > cause ear damage. a harsh-clipped [noise~]-[*~ n] is probably close to the highest loudness you can get, even for not-so-high values of n. However, if you want to find the loudest, you'd have to start from the dBA loudness curve, and try to solve an equation involving a bunch of samples that can range from -1 to +1... at 44100 Hz over 1 second, that'd be 44100 variables, for example, though a lot less variables could be enough to get an idea. It doesn't look like an easy problem to me, but I haven't tried. And then, the loudness curve, the pain curve and the damage curve are three different things. I don't even know whether the latter two have been computed. My only real experience with the loudness curve(s) is from writing Alexandre T Porres' externals (for what he presented in Weimar). I haven't studied the topic much more than that. _______________________________________________________________________ | Mathieu Bouchard ---- tél: +1.514.383.3801 ---- Villeray, Montréal, QC

Re: [PD] multichannel instalation

All that > happens is I get a reduced signal from my 1 and 2 channels coming through > my > 3 and 4 channels. I'm satisfyingly using a Saffire Pro40 on Linux with Pd too, had an installation with 8 channels working flawlessly. Your issue, as IOhannes said, might be about the internal configuration of the soundcard. Since you are on Mac, have you already tried to setup the Saffire MixControl? Basically, you only have to setup the Line Outputs to 8 DAWs, then set eight channels outputs in Pd. http://bit.ly/nAiJxJ cheers, -- Marco Donnarumma Independent New Media and Sonic Arts Practitioner, Performer, Teacher ACE, Sound Design MSc by Research (ongoing) The University of Edinburgh, UK ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Portfolio: http://marcodonnarumma.com Research: http://res.marcodonnarumma.com | http://www.thesaddj.com | http://www.flxer.net Director: http://www.liveperformersmeeting.net
