stackoverflow tag
by Hans-Christoph Steiner 09 Jan '13

09 Jan '13

Anyone on Stack Overflow with more than 1500 reputation? If so, please create a "puredata" or "pd" tag, you need at least that many points to be allowed to do so. http://stackoverflow.com/privileges/create-tags The question is, I guess, should the official tag be 'puredata' so we can beat IBM to the punch, or 'pd'. I think 'puredata' is clearer. .hc

[ pure-data-Bugs-3599983 ] vbap 1.0.3.2 fails when sent longer "define_loudspeakers" me

Category: externals Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: vbap 1.0.3.2 fails when sent longer "define_loudspeakers" me Initial Comment: Using Pd-0.42.5-extended.app, Pd-0.43-3.app, and Pd-0.43.4-extended-20121101 on OSX 10.6x and 10.7x, vbap 1.0.3.2 crashes when sent longer "define_loudspeakers" messages the PD console displays: vbap: Loudspeaker setup configured! pd: getbytes() failed -- out of memory vbap: Configure loudspeakers first! and the program crashes. (It appears to be failing in the "vbap_matrix" method. But, perhaps, the data sent to that message is already bad). Following HCS's suggestion, I tried doubling both MAX_LS_AMOUNT as well as MAX_LS_SETS. Now the program does not crash, vbap fails each time: when sent the define_loudspeakers, the PD console displays: "vbap loudspeaker-matrices: param 475 is not a float." (from vbap_matrix method) Things I have noticed: --The above param number in the error message will be different each time pd is relaunched and a new attempt is made. --increasing MAX_LS_AMOUNT and MAX_LS_SETS 10 times introduces intermittency: Some times the same error message above will be displayed, sometimes it the define_loudspeakers message will succeed, and VBAP will function correctly. -- occasionally, a different error message in the pd console will result: "Dimension can be only 2 or 3" (from vbap_matrix method) --And of course, the problem does not manifest when smaller configurations are used (i.e. shorter define_loudspeakers messages). I wrestled with the problem for a long time without getting any further. Maybe you, or someone out there, will have some greater insight into this problem. Any assistance or additional suggestions would be greatly appreciated, since the problem above comes with the latest pd-extended. Below is the the vbap message that provokes the problem: define_loudspeakers 3 0 90 -7.5 55 52.5 55 112.5 55 172.5 55 -127.5 55 -67.5 55 7.5 20 37.5 20 67.5 20 97.5 20 127.5 20 157.5 20 -172.5 20 -142.5 20 -112.5 20 -82.5 20 -52.5 20 -22.5 20 7.5 -15 37.5 -15 67.5 -15 97.5 -15 127.5 -15 157.5 -15 -172.5 -15 -142.5 -15 -112.5 -15 -82.5 -15 -52.5 -15 -22.5 -15 ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=3599983&group_…

Re: [PD-dev] scale and speedlim

I'm CC'ing pd-dev since others may be interested in the answer as well.

You can also get help on them, then look at the title of the help patch window. In Mac OS X, you can Cmd-click on the filename i.e. "speedlim-help.pd" and then you'll see the full path:

[ pure-data-Bugs-3599847 ] freeverb~ can't handle inf, NaN and subnormals

Category: externals Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Katja (katjav) Assigned to: Nobody/Anonymous (nobody) Summary: freeverb~ can't handle inf, NaN and subnormals Initial Comment: This is about Pd-E 0.42 / 0.43 on Intel Although freeverb~.c has many calls to function fix_denorm_nan_float(), the object can't handle inf, NaN or subnormal numbers. If it gets an inf or NaN accidentally, the only way to recover from recycling NaN's is to reload the containing patch. If normal sound input is stopped, values in the delay lines gradually decay into the range of subnormal numbers, and CPU load increases dramatically. Function fix_denorm_nan_float() doesn't really fix anything, it only returns the input value if it's good or zero if the input is bad. But the return value is nowhere stored. Probably, the function calls aren't even compiled at all for that reason, making [freeverb~] so efficient. SVN shows that the function was introduced in 2007, incorrectly replacing a type punning macro in the original freeverb~.c for Pd/MaxMsp. All together, 40 such calls are intended per iteration of the perform loop, with 3 conditional checks each. If this would be really implemented, my estimation is that it would make [freeverb~] 1.5 or 2 times more expensive. It would be overkill. For all mentioned issues there are cheap and effective workarounds which can even be implemented in a Pd patch. Attached patch freeverb~-test.pd demonstrates bugs and workarounds. One day, [freeverb~] may be rewritten in this sense. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=3599847&group_…

When opening a new window and instantiating [vbap] one gets a version of vbap with only 1 inlet and 1 outlet. As far as I know the working vbap external has 4 inlets and 4 outlets. When opening the help file in the /Resources/extra/vbap/examples/vbap-demo.pd one gets connection errors looking for these inlets and outlets on the [vbap] external. The right clickable help file on this version of the vbap external is also linked to what I'm sure is an old and now defunct help-file. this was also a problem in 43.3 ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=3599843&group_…

from t_symbol to t_class
by Jonathan Wilkes 04 Jan '13

04 Jan '13

Hi list, Since matju couldn't find a way to do this without patching Pd I doubt it's possible, but I want to ask anyway: [symbol clip( | [classinfo] <-- spits out a list of methods, or other class attributes, etc. I can check if clip exists using zgetfn I can get a function pointer to clip_new using zgetfn I assume I can assign t_object *instance using my function pointer to clip_new that I got from zgetfn, but since I short circuited the normal way of creating the object I have no way of knowing what kind of args to send it, so it seems like I'm likely to crash. Is there really no way to inspect class "foo" given symbol foo and proof from zgetfn that "foo" exists? -Jonathan
