Re: [PD] bug in freeverb???

Hmmm, this sounds like underflow traps ("denormals"). You should also be able to add a small constant to the input signal. I notice gcc has the option -fno-trapping-math which may make the problem disappear if my theory is correct. (I hope the FPU simply sets underflows quietly to zero when no trap can be generated.) There is also -ffast-math which is more aggressive. - jos At 11:30 AM 7/1/2009, Matt Barber wrote: >We have also had this problem, and have found that normally one can >avoid it by salting the [freeverb~] object with a minuscule amount of >noise at all times. > >Matt > > > > > Message: 5 > > Date: Wed, 1 Jul 2009 09:57:43 -0700 (PDT) > > From: Andres Ferrari <anfex(a)yahoo.com> > > Subject: [PD] bug in freeverb??? > > To: pd-list(a)iem.at > > Message-ID: <166347.29167.qm(a)web111408.mail.gq1.yahoo.com> > > Content-Type: text/plain; charset=iso-8859-1 > > > > > > when is connected into freeverb any signal multiplied by zero > > the CPU usage begin to up and up to the limit, and if the patch > is heavy by far exceeds the 100%....sound and everything becomes a mess. > > > > This happens to me only in leopard. > > > > In osx 10.4 (ppc) and windows I've never had that problem. > > Andr?s Ferrari G. > > > > http://www.myspace.com/anfex > > > >_______________________________________________ >Pd-list(a)iem.at mailing list >UNSUBSCRIBE and account-management -> >http://lists.puredata.info/listinfo/pd-list Julius O.

We have also had this problem, and have found that normally one can avoid it by salting the [freeverb~] object with a minuscule amount of noise at all times.

bug in freeverb???
by Andres Ferrari 01 Jul '09

when is connected into freeverb any signal multiplied by zero the CPU usage begin to up and up to the limit, and if the patch is heavy by far exceeds the 100%....sound and everything becomes a mess. This happens to me only in leopard. In osx 10.4 (ppc) and windows I've never had that problem.

partconv~ at startup problem
by Mitchell Turner 01 Jul '09

01 Jul '09

Dear all, I am having a small problem with partconv~. When I start a patch that contains partconv~, the partconv~ object will not create (the object looks like a red-dashed box -- I'm using Pd-extended (0.41.4), Mac OS 10.5.7 on a MacBookPro). As soon as I open the help file for partconv~, however, the partconv~ object will create. So at this point, the only solution is to open Pd, then open the partconv~ help file, then open my patch containing the partconv~ object. This does not seem correct to me but, I am not sure how to fix it. Thanks for your time, Mitch

What does it take to do 64 bit?
by Mike Mazarick 01 Jul '09

01 Jul '09

I am running a Fedora linux x86_64 linux distribution (currently, FC8 CCRMA x86_64, with plans to go to FC11 later). I don't mind compiling from sources, but I seem vaguely aware that PD is primarily for 32 bit architectures. The 64 bit version is not easily downloadable in an RPM package, which tells me something. Is PD 64 bit compatible without having to jump thru too many hoops? I haven't been following the thread closely enough to know the current answer. I don't think it has been explicitly stated whether it is "64 bit friendly" since the upgrade in the code a few weeks/months ago. If I have to run some type of chroot 'jail' to run it, it would be nice to know (however, it will be a while before I am motivated enough to set it all up). -Mike Mazarick
