Re: [PD] acquiring information about wav files
there's [soundfile_info) as well, iemlib In fact... And here's an 'unpacked' version of the help ;) Hi all I am looking for a way to get information about WAV files in Pd, specifically the number of channels and the number of frames. I know [wavinfo], but it does not seem to work on windows (error: could not read WAV-header with any file I could find) and on linux it seems to read only a subset of WAV formats. It does not read from widely used broadcast format WAV files. The target platform is windows AND linux anyway in this case, so I need a portable solution. The most troubling fact is, that some Pd-vanilla classes ([soundfiler], [readsf~]) actually do retrieve the information I need, they read both, the number of frames and the number of channels correctly, with all pcm encoded wav files I tried, but - what a pity - they don't expose this information to the patch level. Hopefully I am overseeing the obvious here. Hints are very welcome.

Re: [PD] routing pix_multiimage images to different geos

I've looked at pix_multiimage and it seems this would be a good option to use as all the images are loaded into ram so this should speed things up (the images are quite large - 1200 x 848). So my question is, is it possible to send the output of pix_multiimage to different geos? Can I send image 1 of pix_multiimage to rectangle 1 and image 2 of pix_multiimage to rectangle 2 at the same time? Or would I need to use 2 pix_multiimages? (Which kind of defeats the point) Or is there a better way of doing this? I'd personally try something horribly inefficient but easier for me to understand like this, until GPU memory is filled or CPU-GPU memory bandwidth runs out, at which point I'd use the minimum number of rectangles that fill the screen and draw only those images: [gemhead] | [t a b]/[0( | : [repeat 12] from zexy, or use [gemlist] and [until] | : [t a b]/[f]X[+1] | :\ [pix_multiimage] | : | [pd index to coordinates etc] | | [translate] | [rectangle] Claude -- http://claudiusmaximus.goto10.org I'm not sure I quite understand what you have drawn here...? The use of repeat will make the counter count up to 12 in each frame from the gemhead right? So sending this to pix_multiimage will step through all the images every frame, which is not what I want. I need at least two rectangles, one with image0 textured on it, the other textured with image1 (directly below image0). When image0 has scrolled off the top of the screen, the rectangle should immediately return to the bottom edge of the screen ready to re-enter with image2 loaded from pix_multiimage.. hope this makes some sense. I had a thought of making two pix_multiimages - one with the odd-numbered images loaded and one with even-numbered images - so I'm going to try this first. thanks James ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] pix to polygon

[PD] -..::: Jornadas de musica experiMENTAL :::..-
el fin de semana del 12 - 14 de febrero tenemos hacemos unas jornadas de music experimental en barcelona esta divido en dos partes: BLANKPAGES- una hora de live patching, el 12 de Febrero en NIU-- ... cartel con mas información... http://www.freekculture.net/material/cartles-blankpages-niu-bcn-web.png y el 12 noche y todo el sabado 13 haremos uno taller de pure data y conciertos en los csoa la rimaia y la carbo en NOISE-- se define como todo sonido no deseado por el receptor. En el ámbito de la comunicación sonora es aquel que no contiene información clara que el receptor no es capaz de identificar, individualizar o comprender. …. Una perturbación que sufre la señal en el proceso comunicativo.. …..Un subproducto no deseado de otras actividades. En teoría de la información, sin embargo, se considera al ruido como información. En la música contemporánea, el Noise, siempre ha sido un factor presente en la experimentación y expresión de diversos compositores. La introducción de maquinaria industrial, instrumentos electrificados, y notación aleatorio fue la clave de muchas obras del futurismo, dada, y surrealismo de principios del siglo.. desde la invención del circuito electrónico y el ordenador, el synth ha revolucionado el concepto de la música, fue un proceso muy rápido por parte de los músico en aceptar de nuevos sonidos, filtros y efectos como parte de su paleta de herramientas para la creación sonara, dando lugar al nacimiento de lo que podríamos hoy llamar la musica electrónica.. Dentro de la marco de las jornadas musica experiMENTAL ...NOISE... miraremos la evolución de este genero, estudiamos las diferentes herramientas que tenemos disponibles.. Pondremos en cuestión los convenios de la música comercial,.. el arte no es ni un negocio de venta y compran ni es un privilegio elitista de conservatorio.. la musica como toda formas de expresión artísticas nace de la necesidad del ser humano de comunicar y dejar marcado sus sentimientos mas interiores.. Invitamos que todos sean parte de este lenguaje y que todos expresemos y experimentemos con el medio... En esta primera jornadas nos concentraremos en las bases de la programación .. La base de estas jornadas es el Framework the programación libre PureDATA., un sistema de programación por objetos gráficos, que permite crear diversos instrumentos musicales y que permite la interactividad por parte de sensores, vídeos, y infinitas posibilidades.

Re: [PD] acquiring information about wav files
Just for the record - soundfiler outputs the number of samples directly, so there's no need for [arraysize] in this kind of situation.

[PD] GOP and delta
Hi, I wanted to do make some bangs and canvases disappear and appear on a GOP-enabled abstraction, so I thought the simplest thing would be to make them move outside the gop-area and back to their place. However, when a gui element is moved away from the gop area (via a delta message), it is redrawn outside it. It is not active (i.e. if you click on it you don't interact) but it is still visible. Only when you move the object, then the spurious element previously drawn outside the gop area disappears. The viceversa also happens: you move it back to inside the gop area, it is still invisible; as soon as you move the containing object then it becomes visible. Obviously a bug. The question however is, can anybody think of an easy workaround? thanks m. -- Matteo Sisti Sette matteosistise...@gmail.com http://www.matteosistisette.com ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] acquiring information about wav files
Yeah, but only of the part that you write into the table, which means you have to read the whole file from disk before you know the number of frames (and you need a huge array, when reading a huge file).

Re: [PD] GOP and delta
One thing that you might try is having an extra canvas with a color the same as the GOP patch's background color change vis_size to cover up / hide the stuff you want to disappear. I don't think you can make canvas have a vis_size of 0 0, but 1 1 with the right background color isn't visible in most cases. Of course this doesn't work at all if you intend to move things around beyond simple hiding and showing. It can also be very tedious to set up the visible order and the receive symbols of these canvases, but it does seem to be shown with GOP -Stephen On Fri, Jan 29, 2010 at 4:44 PM, Matteo Sisti Sette matteosistise...@gmail.com wrote: Hi, I wanted to do make some bangs and canvases disappear and appear on a GOP-enabled abstraction, so I thought the simplest thing would be to make them move outside the gop-area and back to their place.

For instance, with a .wav file that's 45205253 samples long (about 17 minutes), this message produces a resize failed error: [read -resize -maxsize 4.52053e+07 test.wav sf-test( But if I resize the table to 45205253 points directly beforehand, a regular read message to soundfiler loads the complete file properly.
