Re: [PD-ot] how low (latency) can you go?

Hans-Christoph Steiner a Ã©crit : > > Honestly, I doubt you could tell the difference between 4ms and 14ms > in a blind test. There have been many studies on this. If you can > detect such tiny differences in onset time, you would be superhuman. Normal humans start to detect a modulation above a difference about 25ms, not even a delay. Anyway, a real instrumentist would obviously be able to play with any amount of latency, and a real director should be able to coordinate different instrumentists. Take the violin section for example, the sound comes out from this instrument group a long time after strings starts to be rubbed. The location of different instrumentists in the concert room is also a cast that the director shouldn't neglect if he don't want all instrumentists to be loosed in a soup of delayed attacks caused just by the sound's travelling in atmosphere. ___________________________________________________________________________ Yahoo!

[PD-announce] netpd-shuffle: the netpd-radio
by Roman Haefeli 18 Dec '06

18 Dec '06

hi all netpd-shuffle, the netpd-radio-stream, plays just everything that ever has been recorded from netpd-sessions. there is also an ANTI_BOREDOM_BUTTON on it's webinterface, that is to press, when a session lasts for a too long time and is going to become boring (some sessions are more than an hour long and stay the same for some time, because everyone is chatting instead of making music.... ;-) http://www.netpd.org/listen --this is all stuff made purely with puredata-- on the same stream livesessions will be broadcasted, that hopefully will happen every thursday @ 9pm GMT. everyone is kindly invited to participate. cheers roman ___________________________________________________________ Der frühe Vogel fängt den Wurm.

hi mark quite a few applications are involved: -a bash-scripts (wget, sed, etc.) creates a actual playlist (m3u) from the apache-directory-list -mplayer is started with '-input file=<fifo>'-flag and plays the m3u-file in shuffle mode. trough the fifo it can be controled by any other application -mplayer connects itself with puredata over the jack-server. -a puredata-patch converts the audio into a mp3-stream using the [mp3cast~]-object from y.degoyon's unauthorized. it's maybe not too straight forward to go over pd for that purpose, but i like to have the opportunity to process the stream (gain-control [which i plan to implement], add jingles or whatever) -an icecast-server receives the mp3-stream from pd -a little php-script sends the appropriate command to the fifo, that is read by mplayer, when the button on the webpage is clicked. roman On Fri, 2006-12-15 at 06:19 -0800, mark edward grimm wrote: > hey roman, > > just curious what software you used for the streaming > radio... icecast or something to that effect? > > BTW. the shuffle option is pretty cool....:) > > cheers > mark > > --- Roman Haefeli <reduzierer(a)yahoo.de> wrote: > > > hi all > > > > netpd-shuffle, the netpd-radio-stream, plays just > > everything that ever > > has been recorded from netpd-sessions. there is also > > an > > ANTI_BOREDOM_BUTTON on it's webinterface, that is to > > press, when a > > session lasts for a too long time and is going to > > become boring (some > > sessions are more than an hour long and stay the > > same for some time, > > because everyone is chatting instead of making > > music.... ;-) > > > > http://www.netpd.org/listen > > > > --this is all stuff made purely with puredata-- > > > > on the same stream livesessions will be broadcasted, > > that hopefully will > > happen every thursday @ 9pm GMT. everyone is kindly > > invited to > > participate. > > > > cheers > > roman > > > > > > > > > > > ___________________________________________________________ > > > > Telefonate ohne weitere Kosten vom PC zum PC: > > http://messenger.yahoo.de > > > > > > _______________________________________________ > > PD-announce mailing list > > PD-announce(a)iem.at > > http://lists.puredata.info/listinfo/pd-announce > > > > _______________________________________________ > > PD-list(a)iem.at mailing list > > UNSUBSCRIBE and account-management -> > > http://lists.puredata.info/listinfo/pd-list > > > > > ____________________ > mark edward grimm | m.f.a | ed.m > megrimm.net | socialmediagroup.org & .com > meg156(a)columbia.edu | 585.509.8703 > ______________________________ > > > > ___________________________________________________________ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de

DesireData CVS
by Mathieu Bouchard 17 Dec '06

17 Dec '06

just to say that the DesireData CVS is back to being its own branch. For new instructions, please see: http://desiredata.goto10.org/wiki/QuickStart or else just update your existing checkout like this: cd pd cvs update -r desiredata because if you just do "cvs update", you will just wipe DesireData from that directory (as I removed DesireData from devel_0_39 and doing just cvs update would sync with that). The reason for this, is that the number of differences between the regular devel_0_39 and DesireData is increasing too much these days, and especially the upcoming changes this month. _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard - tél:+1.514.383.3801 - http://artengine.ca/matju | Freelance Digital Arts Engineer, Montréal QC Canada

Hi Hans Thanks for that. Unfortunately its not working for me at the moment. The object creates ok, but pd quits with no warnings or dialogs whenever you send a message into the inlet. I'm trying it with Pd-0.39.2-extended-test5, Mac 10.4.8 Will try it on another machine just to make sure its not something with his machine. Happy to try things if anyone has suggestions. I downloaded the max demo and the max object works and syncs to the wii remote - I will make something in Max for now as I have 30 days of the demo to go.

Bryan Jurish a Ã©crit : > since i'm just plain not good enough to compensate before the > glitches become painfully audible... > > marmosets, > Bryan > It becomes really difficult if you add the latency caused by the the sound in air. I've experience this once I was playing guitar at the control table while the speakers was at twenty five meters, and I can tell that it's more easy to play in those conditions when the guitar is directly plugged into the the amplifier, instead of passing through a soundcard, with some amount of latency, that is affordable with headphones. p ___________________________________________________________________________ DÃ©couvrez une nouvelle faÃ§on d'obtenir des rÃ©ponses Ã toutes vos questions !
