Re: [PD] changing volume depending on frequency
Hallo, Andy Farnell hat gesagt: // Andy Farnell wrote: One thing you might like to look at is the Fletcher Munsen curve. There isn't a hard mathematical relationship between perceived amplitude (loudness) and frequency, it's more of a biological and psychoacoustic effect, and somewhat subjective between listeners. http://ccrma.stanford.edu/CCRMA/Courses/SummerWorkshops/96/Psychoacoustics/labs/loudness/ The Pd solution to this is to use lookup tables to scale amplitude, a bit less fiddly than setting up a piecewise function. Also see [mtx_phon_curve] in Iemmatrix.

Anyone have any ideas along that line? I guess one the problem is, that /etc/security/limits.conf is not a per-application but a per-user (including per-group) setting. so it does have side-effects, which is probably the reason why there is no such thing as you asked for. fmgasd.r IOhannes ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Can anyone make a wiki page about this on http://puredata.org/docs ? It would be quite handy to have. Also, I'd love to hear suggestions how to make this part of the Pd- extended package. I think it makes a lot of sense to have this a debconf question.

Re: [PD] Poll: Ctrl-click to toggle editmode
I found the Max/MSP style Cmd-Click to toggle edit mode quite annoying in Pd. So I switched it to the Pd-style Ctrl-Click. Cmd- Click now allows you to interact with GUI objects when in edit mode. I think this makes the most sense. Any objections? .hc On Jul 13, 2007, at 9:24 PM, hard off wrote: command E / ctrl E, which i have always used, is weird now on osX . for a start, you have to actually move the mouse to see the cursor change from an arrow to a hand. also, if you use command E with the mouse clicked (when selecting objects for edit), then command E is double triggering. i could possibly get used to the new command click method, but just want to let you know that this change has broken the existing command E function. my vote is a NO for command click unless the original command E function works properly again.

[PD] Can't use standard C libraries on external compilation for windows using MINGW
Hello:
I followed Alberto Zin's instructions for compiling pd
externals using Mingw and they worked OK.
But:
I modified de hello.c code adding the opening and
closing of a file. Of course, the stdio.h header
file must be added to the code.
Attached to this message is the modified hello.c.
The code compiles Ok, and I get the hello.o using the
following command line:
C:\pd\isidro\hellogcc -c hello.c -o hello.o
But when I try to link to get the Dll file, I get the
following message:
C:\pd\isidro\hellold -export_dynamic -shared -o
hello.dll hello.o c:/pd/bin/pd.dll
hello.o(.text+0x16):hello.c: undefined reference to
`fopen'
hello.o(.text+0x30):hello.c: undefined reference to
`fclose'
The same I get if I use some Standard Library Function
like string.h or other...
Maybe I am doing something really stupid but if you
know what's up it will save lots of time to me...
Many thanks

Re: [PD] setuid WAS Re: Pd-0.39.2-extended-rc4 released on ubuntu
Hi Hans, In general, I've held off fixing bugs in 0.39 for fear of introducing new problems, especially since you've been working for so long to get Pd extended out. But this one is special since it's a security leak, so I'm inclined to fix it. If past experience is any guide, I'll make a mistake in a CVS commit and wreak havoc that will take days to clear up. Well, maybe not, who knows. I'm hoping it will prove easy enough to plug 0.40 into the extended release mechanism that for non-security bug fixes, it will suffice for me to fix them in 0.40 and wait for the march of time to propagate the fix. For instance, once I find the open-GOP-close-patch bug, I can fix that both in 0.40 and latest but leave 0.39 alone. Unless there's reason not to, I'll take the single offending 'e' character out of 0.39, tag it 0.39-3, and commit... ? cheers Miller On Sat, Jul 14, 2007 at 12:33:25PM -0400, Hans-Christoph Steiner wrote: On Jul 13, 2007, at 3:36 PM, Mathieu Bouchard wrote: On Thu, 12 Jul 2007, Hans-Christoph Steiner wrote: This is only possible if you are running Pd as root, which is general is not a good idea.
