Re: [PD] Measuring position between two microphones?
Another thought... When you have the two microphones, just correlate the noise between the two channels (not from the output/input1 and output/input2, but between input1/input2). When the speaker is equidistant from each microphone the delay is 0 (located at exactly half a block on the output from sxcov~.pd or sxcorr~.pd). Then, the distance from the center is simply proportional to the measured delay between the signals, divided by 2. e.g. at 44100 kHz, given c=343 m/sec distance from center=(delay in samples)/2/44100*343, meters and the resolution is about 4 mm noted difference: sxcorr~ accumulates it's values over time, so that you can get more accuracy, from using longer signals sxcov~ is instantaneous and not accumulated Chuck ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] pd gem on multiple cpus: howto use???

If you have an SMP kernel, the kernel will do it for you. one running a gem patch and other with a pd audio patch? and the best way to communicate between these 2 instances is OSC? Either OSC or FUDI (with netsend/netrecieve) if i record all OSC messages that i send to gem patch i imagine that i can render everything non-realtime later also - with better resolution/size... does anyone works this way? some guidelines would be very helpful... I do something similar: I print all the messages I send to the terminal, with time stamps. pd -stderr performance.log 21 then some 'sed' magic to remove the print: prefixes and load it into qlist with read performance.qlist cr, then play it back to render in DVD resolution. The advantage of going via the terminal, is that if Pd crashes I still have the log up to that point - hasn't happened yet, though. i am on slackware 12 RC1 Linux igorpc 2.6.21.5-smp #1 SMP PREEMPT thx in advance igor Claude ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

hello, Igor Medeiros a écrit : hi all how can i use 2 cpus with pd? i know i can open 2 instances of pd, but how can i assign each one for a different cpu? the OS should do it for you. one running a gem patch and other with a pd audio patch? this is a good solution if you gem patch is really CPU intensive. by exemple, loading images will not stop audio rendering. but usually (depending on your patch in fact), gem is GPU intensive, a gem patch should not use lot's of CPU. and the best way to communicate between these 2 instances is OSC? netsend / netreceive work great, without any externals. if i record all OSC messages that i send to gem patch i imagine that i can render everything non-realtime later also - with better resolution/size... does anyone works this way? some guidelines would be very helpful... i do use this trick for recording all frame on the HD, in order to create some good quality movies of the gem windows. I record everything in a qlist and play this qlist slower. I slow down gemwin frequency on the same proportion. if your gem patch use line, delay or pipe object, you also need to slow them down also. when creating this qlist, you nead to take care : delay 0 is not the same as no delay. cyrille i am on slackware 12 RC1 Linux igorpc 2.6.21.5-smp #1 SMP PREEMPT thx in advance igor ___ 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

I didn't bother doing this, I just let Pd do the slowing down itself, seemed to work ok. The machine at full load for 6 hours to render a 30min video did get quite warm when creating this qlist, you nead to take care : delay 0 is not the same as no delay.

Re: [PD] Teaching Pd
Thanks guys for your feedback! I'm trying to explore what my best usages of Pd have been, and what I might have to offer to people starting out. Your tips will go a long way! ~Kyle On 6/24/07, Andy Farnell [EMAIL PROTECTED] wrote: On Wed, 20 Jun 2007 00:18:23 -0500 Kyle Klipowicz [EMAIL PROTECTED] wrote: Hi List~ I'm curious about teaching Pd to interested people, and know that a number of you have given workshops on the subject. I could really use some collective wisdom on this. Teaching Pd is something I really enjoy. What I've seen so far are great differences in audience goals and the need to prepare and research exactly who you are talking to and why, because Pd has such wide applications. Look for your own niche skill that Pd allows you to express and use that as a guide. What methods do you use to structure and communicate your course material? How do you market it within the city that you are teaching? What sorts of materials do you use? Often people bring their own laptops and headphones. The best format imho is lots of practical elements, short exercises that can be done individually or in small groups, keep dove-tailing talk time with hacking time. If machines are available but are administrated workstations it helps to take live CD environments so you aren't treading on anyones toes having groups of students install stuff. Or make sure whoever invited you or organised the talk has done the groundwork for any practical element. A copy of PureDyne is useful, with the patches used in a workshop handed out on thumbdrive, by web-site or burned into the distro. For the cost and time it takes to run off a dozen copies it's worth it for everyone to take home a workable Pd environment for the PC. I guess it depends on whether you're teaching audio, video or physical computing what needs and priorities you might have. For audio I always want a good stereo sound system and a pocket mixer is a useful gadget. For Gem/Visual presentations I suppose you'd spend more thought on the beamer resolution and framerate. For physical you need desk space where people can play with components and wires. Often it's requested that laptop users install Pd on their machines and get it running before coming to a session, that way everyone is ready to go *and* they can take their work home with them. What makes it fun imho, and possible to make focused presentations, is the flexibility of Pd as a teaching tool... it's almost designed for the job! Using Pd itself as the presentation tool, making folders of patches that are linked as slides, and having it self document to pdf handouts and html resources are things I've put a bit of thought into. It's nice if you have a LAN available so you can go into the network parts of Pd. A good finale is to get everyone jamming with some OSC net-pd type patches linked together. For finding audiences, I think the same as Alexandres advice, technical and art colleges and universities doing interactive design, music technology and courses like that. I specialise in audio so I try to use Pd as a vehicle to teach it, rather than generally all about puredata which is quite beyond me. And also try to get groups of producers from standard industry roles interested too, Pd is obviously very enabling in radio, TV, film, animation, games and theatre. To teach Pd generally, finding colleagues is as important as finding audiences. I don't think anybody could tackle the entirety of Pd and it's applications alone without it being a very dull, highly structured and long exercise. I sometimes pair with someone who is teaching visuals or composition or something else that complements my stuff on audio synth. Work together to put on events. With groups of more than 15-20 having a buddy as an extra demonstrator/helper in practicals is essential or you can't give everyone enough 1 to 1 contact time. Best all round Pd presentation I have attended was organised by goto10 at space studios as a summer school with several specialised Pd users teaching individual areas in a structured programme so that the whole 2 week event became more than the sum of its parts. my waffling 2c... hope that helps Andy -- Use the source ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list -- - - - -- http://perhapsidid.wordpress.com ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
