I've read further and searched the archives of the list. Is this related to denormals?
Isn't pd now handling denormals correctly? (that is, avoiding them) I mean vanilla 0.40. I ask that because I've seen discussion dating back to 2003 about this issue. Is it still an issue? Another thing I don't understand is why that is a problem only in pentium4: don't other processors have denormals as well? thanks m. ----- Original Message ----- From: "Matteo Sisti Sette" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Wednesday, May 02, 2007 12:36 PM Subject: P4-optimized 0.40 vanilla precompiled for windows? Hi, I'm having the "CPU jumps after a while" problem. That is, the same patch which at the beginning is consuming about 30% of CPU, after a while it is running (and absolutely nothing changes in it, and I am totally sure this is true) suddenly jumps to a CPU consumption over 70%. I've read in the archives it is an issue specific to Pentium4, and that there is an optimized version of PD that solves it. Is there a 0.40.x pentium4-optimized version of pd-vanilla precompiled for windows? If so, where can I find it? Thanks a lot in advance bye m. ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[email protected]> Sent: Wednesday, May 02, 2007 12:00 PM Subject: PD-list Digest, Vol 26, Issue 7 Send PD-list mailing list submissions to [email protected] To subscribe or unsubscribe via the World Wide Web, visit http://lists.puredata.info/listinfo/pd-list or, via email, send a message with subject or body 'help' to [EMAIL PROTECTED] You can reach the person managing the list at [EMAIL PROTECTED] When replying, please edit your Subject line so it is more specific than "Re: Contents of PD-list digest..."

The example refers to re-triggering something like a percussion sample - it is a way to fix the glitch resulting from suddenly cutting off the 'old' sample (which is likely not at a zero-crossing) and replacing it by a new one (which starts at zero). The flowchart shows adding a signal ramping to zero from the last value of the 'old' sample. That is: the whole example/technique described depends on the assumption that the re-triggered sample starts from zero, it doesn't make sense otherwise. simon ------------------------------ _______________________________________________ PD-list mailing list [email protected] to manage your subscription (including un-subscription) see http://lists.puredata.info/listinfo/pd-list End of PD-list Digest, Vol 26, Issue 7 ************************************** -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Vuoi essere in grado di saper scrivere un Business Plan vincente?
