well this here: /usr/local/lib/libfftw3f.3.dylib doesnt actually exist at all instead its here: /sw/lib/libfftw3f.3.dylib but thats just from the binary you offered and not compiled by me. the other thing is i had to add [import py] for [pyx. 1 2 noteflt] to load. thanks! m On Fri, Nov 2, 2012 at 9:54 AM, Thomas Grill <gr(a)grrrr.org> wrote: > Hi, > i guess that the FFTW3 library you have installed doesn't contain a 32-bit binary. > gr~~~ > > PS.

Readanysf~ supported audio formats
by Pierre Massat 06 Nov '12

06 Nov '12

Dear List, I've been using readanysf~ on the RPi for a while to read audio streams from the internet. I have noticed that some streams won't play, and I get a "unsupported codec" error. I have found this list of supported formats on the web (http://www.mail-archive.com/pd-list@iem.at/msg43994.html), according to which the formats i get an error with should play fine. I have installed readanysf~ on Raspbian the normal way (apt-get install pd-readanysf), but I'm not sure the version in the Debian repository was compiled to support every format. Do you think this is possible ? Is there a way I can check this ? And - even better- fix this ? Cheers, Pierre.

constantq~ - spectral analysis for Pure Data and Max
by Thomas Grill 06 Nov '12

06 Nov '12

Hi all, here finally the external object that is central for the cq2midi application posted earlier. It has already been sitting unpublished on my computer for too long. It can be a valuable tool for general spectral analysis. Contrary to the FFT the frequency scale can be freely adjusted. Binaries are currently provided only for MacOS (Pure Data and Max), but the source code is open (GPL licensed). http://grrrr.org/research/software/constantq gr~~~ -- Thomas Grill http://grrrr.org

MacOS externals 32bit+64bit
by Thomas Grill 05 Nov '12

05 Nov '12

Hi all, this is to let you know that i compiled "all" my published externals as 32bit/64bit fat binaries. The externals should work for Pd-vanilla and Pd-extended, both in 32-bit and 64-bit mode. 32bits are tuned for nocona architecture, 64bits for core2, both should be compatible with MacOS >= 10.5. Unchanged are some externals that are no longer actively maintained by me. http://grrrr.org/data/dev/ext/macos/pd have fun, Thomas -- Thomas Grill http://grrrr.org

vline~ precision under lower block sizes
by João Pais 05 Nov '12

05 Nov '12

(according to the pd-list server this message came attached to thread of another mail, I try to send it here again to create a new thread) Hello, a friend noticed that vline~ behaves differently with different block sizes - namely that the smaller the block size is, the less precision it has. Besides the numbers being different with each block size, the latest values go slightly over the border of the desired range. Is this a bug, a feature, or an unavoidable behavior of the vline~ algorithms? Attached is a patch which explains the situation. I think it should be clearly enough explained. The bottom line is: in the patch I am working, block size is 1 (sample rate 48KHz, in case it matters). Which choices are there to improve vline~'s precision, so that I get the results I am expecting? Thanks, JoÃ£o

compiling externals for osx i5/i7
by Orm Finnendahl 05 Nov '12

05 Nov '12

Hi list, I just found out that some of my custom externals stopped working on recent OSX (i5/i7) hardware (pd complains about arch mismatch). Since I don't own Apple gear I always compiled on a (virtual) OSX machine on my linux box. I'd rather avoid having to update the virtual box once again to a more recent OSX version, put the XCode stuff on it and spend hours after hours just to get a compilation environment. My questions: - is there any way to make gcc cross compile for OSX on linux? - is there an extension for i5/i7 and dual-core externals on OSX so that they can co-habitate with each other (similar to the .l_ia64 and .l_i386 on linux)? - is a recompilation for linux i5/i7 hardware also necessary (and what's the extension for that)? Thanks for any hints, Orm

Updated Resources for Miller's "Intro" Videos
by Joe Deken 05 Nov '12

05 Nov '12

All 20 of the Miller Puckette's "Intro to Computer Music ..." video transcripts are now updated, with accurate time-codes more suitable for translation and/or use as subtitles augmenting the Intro videos. The formats of the transcripts available are: -- .txt : English original text, with 15sec time-codes embedded -- .doc: Table format with time-codes duplicated, for interlinear(synched) translation -- .html Table format with time-codes duplicated, for interlinear(synched) translation Also: 2) These English versions, the "best edited" available for now, are at: http://newblankets.org/MUS171_supplements/MUS171_transcripts/ 3) Added now to the URL are some very rough translation *examples* of complete lectures: Russian (1,10), Spanish(10), French(10) and German(10). These are machine/automatic translations with pervasive, systemic mistakes, but they are certainly intelligible. So they may useful, on a temporary basis, or as editable starting-points for real, human translators to work with. (Time-codes are preserved as well in these rough translations.) If there is interest, some of the "rough translation" sets could be filled out, at least some languages, to completely to cover all 20 lectures. 4) It would be worth knowing if there are other languages where people would find these sorts of resources helpful and/or if additional rough- translations in other languages should be added to the page. helpful.
