[PD] Re : Split multichannel audio file into stereo pairs
Hi You could use [readsf~ 12] to read your file and then several [writesf~ 2] to record, but i guess you want something faster...

I want to split a 32-bits 12 tracks audio file (aif) into 6 stereo files (consecutive pairs i.e. 1-2, 3-4, etc.). I've already tried with [soundfiler], but there seems to be many problems with large files (this one is aprox. 10 minutes lenght) and with 32-bits reading (I listen a kind of quantizing error noise, a sort of dithering-less noise). In fact, I'm thinking of reporting a bug on it, but I'd have to explain which exactly the problem is, and I need some time for that.

[PD] PDF of Kreidler´s Loadbang book
Hi all. I´m new in Pd and the Pd-list. I built a PDF file of the English translation of the Johannes Kreidler´s book Programming Electronic Music with Pd also known as Loadbang and I think that this could be usefull for everybody. I maid this only with the English translation because is the only language I can read so far (I`m brasillian). But there is one problem in the file: I had to squeeze some images so they can fit in the page (I used A4 because is the regular size here in Brazil). So I included in the zip file the .odt (OpenOffice) file that I used to build the PDF so I guys can maybe make some changes to make it look better, if you will. Anyway, here is the download link: http://rapidshare.com/files/245237474/kreidler_pemwpd.zip.html Best of all Caio G. de Barros ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] Techniques for atomic/controlled variable updates
Thanks to both Jonathan and Frank for your replies. Took me a bit, but I now understand the pack list suggestion. I still fear I may have issues once I unpack the list (as, it will resume the right-left propagation of those values into the rendering piece of the patch), but this gives me a better understanding of the tools to use for ordering messages.

I really wonder what is the point to do such a thing in Pd - there are different tools for different task, 'one size fits all' is an almost religious illusion... audacity does changing file types better than any app that I know. there's to the left side of the window at the name of the file a pull down window that allows you to split, glue together etc exactly as you want to. attachment: filetype_pull_down_auda.jpg inline: filetype pull down auda.jpg solo the tracks that you want to export as stereo, click make left the one you want to be left and make right you want to be right. than click make stereo and export. and then the next pair of tracks.
