[PD] osc~ / phasor~ / cos~ ...sometimes clicking
has anybody else experienced small clicks every now and then from pd's oscillators? i have noticed it before with [phasor~], and today i was getting it pretty badly with [cos~]..about 1 click every 10 seconds. this is nothing to do with the contents of the patch, because just a [cos~] connected to a [dac~] was making the same thing happen. ...it's nothing to do with dac~ or my sound hardware either, because disconnecting the [cos~] from the [dac~] stopped the clicks. ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

hi hardoff i would make sure, that these clicks are not dropouts. i mean, you won't hear dropouts without sending an audible signal to [dac~], so just disconnecting the [osc~], so that you hear no clicks anymore, is not a prove, that you do not have dropouts. i don't know if it works on every platform, at least here on linux, when running pd with jack, the [DIO] button in the pd-window indicates dropouts. if you still believe, that the [phasor~]-[cos~] combo is causing the clicks, you could record the output with [writesf~] and open the recorded wavefile with a soundeditor to see, if you can find the clicks. if you find clicks in the soundfile, then something really scary is going on :-) roman On Wed, 2006-11-29 at 00:01 +0900, hard off wrote: has anybody else experienced small clicks every now and then from pd's oscillators? i have noticed it before with [phasor~], and today i was getting it pretty badly with [cos~]..about 1 click every 10 seconds. this is nothing to do with the contents of the patch, because just a [cos~] connected to a [dac~] was making the same thing happen. ...it's nothing to do with dac~ or my sound hardware either, because disconnecting the [cos~] from the [dac~] stopped the clicks. ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

There's a subtle error in your diagnostic procedure. Because disconnecting [cos~] or [phasor~] causes the click to vanish it doesn't imply strongly that [cos~] or [phasor~] are the sorce of the problem. :) Try it with a [sig~ 1] and tell me what you get.

Consider that digital audio is represented simply as instantaneous pressure values for the speaker membrane. This problem is actually quite common when you change from a positive or negative pressure value to a null crossing in the space of one sample. The solution is to use some kind of envelope generator scaling before passing your audio output to the [dac~]. ./d5 On Nov 28, 2006, at 9:01 AM, hard off wrote: has anybody else experienced small clicks every now and then from pd's oscillators? i have noticed it before with [phasor~], and today i was getting it pretty badly with [cos~]..about 1 click every 10 seconds. this is nothing to do with the contents of the patch, because just a [cos~] connected to a [dac~] was making the same thing happen. ...it's nothing to do with dac~ or my sound hardware either, because disconnecting the [cos~] from the [dac~] stopped the clicks. ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Clicks are most often CPU / buffer related problems, however. On my laptop, for instance, I have to disable the wireless card if I want to use even a very simple PD patch and not get clicks, for example. I have to disable it for using other audio apps, also - but the problems in PD are always more severe than any other audio program. ~David On 11/28/06, day 5 [EMAIL PROTECTED] wrote: Consider that digital audio is represented simply as instantaneous pressure values for the speaker membrane.
