Lot of audio > processing, that > might set the minimum of cpu power. quite complex patches, I said. by the way, implementing all sort of synthesis algorithms. for instance, granulation algorithms with a lot of granulators changing granulation parameters depending on incoming values from an accelerometer that is giving values to the serial port. also, multiple fft filtering instances behaving independently, and so on...

I believe there shouldn't be big problems here. despite of I don't have a very big experience in linux -I've just administrated one server running linux-, I know quite deeply other operating systems belonging to the Unix family. > > There are distributions that work more or less out of the box... > DEMUDI or > Planet CCRMA or even a live cd like dynebolic could do the job..if > you want > maximum optimization and spend a lot of time you should go with gentoo well, if I ask here, it is because I haven't a lot of time to research by myself :( > > Anyway... > > Tell me more...i am happy to help > I think I'll have a lot of questions for you after having made some decision, bought a computer and a soundcard and installed a linux distribution ... anyway, I hope when linux and hardware have been sucessfully installed, the pd installation is quite straigthforward. or not? > > saludos > > Luigi grazie! jose manuel

long sound samples
by altern 29 Dec '05

29 Dec '05

hi I need to play several small loops from a pretty big sound (500M). I would like to use xsample external as I need to change pitch, etc ... But the file is too big to load it into the soundfiler. Loops are chosen according to some rules from a starting point onwards, I should be able to change the starting point on the fly. Sorry, difficult to explain. Before I had something similar that was sampling a sound stream from a cd player I was manipulating, but now i want to reproduce this with a sound file as the sound source. How should I go about this? I was thinking that maybe I should copy the parts of the sound I need to use into tables to later play them? I remember there was an external to do this (copyarray maybe?) but I am not sure this is the right way to solve the problem. But for this I would need to have the sound imported into a table already. Is there a way to load only one part of a sample into a table? thanks! -- enrike

readsf and filelength
by Peter Plessas 29 Dec '05

29 Dec '05

Dear List, trying to get the absolute time of a file i want to play with sfplay/readsf~. Like a 3rd outlet which would give you the total length in samples, at loading the file. Found some old posts on the list from 2000 when the discussion arose around IOhannes writing zexy, but without success, and am wondering if this has been tried somewhen. Any ideas? PS: IOhannes: why are sfplay and sfrecord spelled without a tilde? lg, Peter

jpeg patchworks with Gem ?
by Alexandre Quessy 29 Dec '05

29 Dec '05

Hi ! I am looking for a way to combine many jpeg images with Gem in an interesting way. Anyone has some experience to share ? I have several files which I know their sizes, and I would like to change their size, tranparency, to add pix_* effects, gradient map (not much posible though), etc. on them. I might have 10 images at a time. I guess I should use 10 rectangle on which I pix_texture my pix_image, right ? Any hint on blending such pix_images ? thanks ! -- Alexandre Quessy http://www.sourcelibre.com/

using PD on PDAs
by duncan 28 Dec '05

28 Dec '05

hi everyone, just joined the list so i suppose i should introduce myself! i'm duncan and i make a lot of sound installation stuff, been using max/msp for quite a while and i feel like making the jump to pd. so my main enquiry line (you knew it was coming!!) is about making pd work on PDAs? has anyone had any experience of this? I searched the list but only found some references to getting midi in (and sadly the URLs mentioned were defunkt), i want to be able to to do some simple audio processing.. so any ideas on which PDAs this might work on, and what OS i would need? i'm pretty new at this backend game so any advice is appreciated.. i know it's possible to run linux on some PDAs but is this the way to go? be well duncan -- <URL: http://29fragiledays.blogspot.com > <URL: http://www.kleindesign.co.uk
