Re: [PD] bang vs empty list
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 On 2013-03-01 18:03, Ivica Bukvic wrote: This makes perfect sense. However, I have at least a couple of patches where I have a select connected to a networked stream of messages one which includes bang. So after I have to appied IOhannes' patch, this effectively resulted in a regression where bang messages were not recognized by the select object, throwing a large number of errors. While one can argue that this is simply a poorly designed patch the other side of the coin is to say that this latest addition has caused a breakage in the existing patches as this problem was never reported by pd before and now is causing xruns. I also hear your call for consistency so I am open for going either way particularly because the example you gave did not use select. After all what follows from select is nothing more than a bang while symbol bang would be intercepted anyways. thanks for the test. however, i'm not entirely sure whether this is really a regression (or a poorly designed patch). my patch will make empty lists do something meaningful (that is: check whether the object can handle them) rather than simply ignore them, but that was the point of the patch. before my patch, [select] would emit a no method for 'bang' whenever it received a [bang(, and it would do nothing when it received a [list( (neither accept nor reject the message through it's designated outlets). now it will emit a no method for 'list' whenever it gets a [list(, and retain the original behaviour for all other messages. this is the intended behaviour. i tried to reproduce your test-case, but it seems to behave differently on pd-vanilla than on pd-l2ork. this is what i tried: [connect localhost ( [r data] | | | +-+ | [netsend] [netreceive ] | [select] doing a [;data send bang( will give me a select: no method for 'bang' both with and without my patch applied. doing a [;data send( will give me nothing both with and without my patch applied (since [netsend] will not send an empty message). could this be a regression in [dsis_netsend]/[dsis_netreceive] that has been exposed by my patch? maybe it would help if you posted a patch that exposes the problem. fgmasdr IOhannes -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAlE0WiMACgkQkX2Xpv6ydvRsxwCg8vxkb3JB4SKisMki5J5twdPD K98AoIEsBMLZ1KNrUvhDZfTuYaHEgu+M =Sr1k -END PGP SIGNATURE- ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] playing sound files

Re: [PD] file format for GEM
I am using pix_film to play back the files, do I need to use another object? I ask because when I send the messages auto -1, 1 or 2 into the first inlet, the playback is always the same (1), and if I send auto .5, it turns off (as with 0).

Re: [PD] wireless audio from Pd to PA system (katja)
Sending Pd-audio over Wifi would have the advantage that no extra gear is needed at the transmitter side, simplifiying the setup of a wearable live performance computer. Therefore this would be the method of my preference, if it is possible at all. This weekend I did some experiments with [udpsend~] and [udpreceive~] over Wifi. I soon found that using a wireless router makes little sense. Wifi is 'half duplex', meaning it can't send and receive at the same time, so the router is either receiving from one computer or sending to the other. A waste of time. I learned about 'ad hoc networks', where computers can be paired via Wifi and talk to each other directly, without a router. Never knew about this before. What a cool option that is. Found a howto here: https://help.ubuntu.com/community/WifiDocs/Adhoc In ad hoc mode, latency is lower, although on average not as low as over cable, and with more fluctuation. Moreover, there was considerable packet loss, which did not happen in wired LAN. Therefore, tcp protocol should probably be used instead, to check for packet loss and eventually resend packets. I found that [udpsend~] can not send packets of 64 samples. It seems that 256 samples is the minimum. Why? Maybe it is best to pack each signal vector in a list and use the [tcpsend] / [tcpreceive] combo instead. A well-known issue with music streaming is clock drift, caused by the slightly different clock speeds between audio cards. This also happens when sending over a local network (wired or wireless). Clock drift is typically 0.0001 to 0.001 ratio of nominal sample rate. A small difference, but it causes one buffer to be skipped or duplicated once in a while. To compensate, the signal should be resampled to match the receiver's sample rate. This would not require a complicated interpolation scheme, but still it would probably need one or more new Pd classes. An interesting article about clock drift and possible solutions is here: http://www.carot.de/Docs/AES_Tokyo.pdf If further experiments are promising enough, I would try this board for the receiver: https://www.olimex.com/Products/OLinuXino/A13/A13-OLinuXino-WIFI/ Otherwise, I would just be happy to have learned about ad hoc networks. This can come in handy for other purposes too, for example when synching Pd computers.

They do not write it in the specs, but most users don't notice latency and when they do, their support is speaking of latency as low as that: http://line6.com/support/thread/33898 This weekend I will do some WiFi experiments and see how fast it can go locally, using mrpeach udp and tcp classes. If it works, one could use a wireless router which has no other task than routing Pd audio, and the computer at the receiving end could be a cheap headless board with no other task than receiving Pd audio and converting it to analog. Together the receiving device could be the size of a weight-watcher's lunch box, while at the transmitter side the computer's built-in stuff is used. Maybe I'm a bit naive here, anyway I'll report results from experiments. Katja On Fri, Mar 1, 2013 at 2:14 PM, richard duckworth richduckwo...@yahoo.com wrote: OMG - that's really high!

[PD] [PD-announce] Concordia Laptop Orchestra and Acoustic Friends - Liveware! This Thursday (March 7th @ 7P)
Concordia Laptop Orchestra and Acoustic Friends - Liveware! Thursday, March 7th, 2013 @ 19:00 Concordia Music Department John Molson School of Business 1450 Guy St., 8th floor, room 245 Also webcast (see below) Free admission! This Thursday at 7 PM, come join Concordia Laptop Orchestra (CLOrk) for a casual evening concert with some excellent pieces by Michaël Bresse, Joe Browne, Michael Palumbo, and Ryan White, plus a closing CLOrk beat-jam. Each piece utilizes the laptop orchestra medium in a very different manner: In Michaël Bresses’s piece, the laptop orchestra will explore texture and space under his conduction. In Joe Browne’s piece, bass trombonist Felix Del Tredici will interact as soloist with the laptop orchestra and with snippets of his own live sounds processed and spatialized in 8 channels. In Michael Palumbo’s piece only one computer will play a sound, but 20 people will shape and transform it. Ryan White’s meditative piece with Christian Brun del Re (drums) will utilize the laptop orchestra as a glitch percussion ensemble. CLOrk’s beat jam is like… Mouse on Mars meets Autechre meets Tam Tams Montreal. The show will be webcast (audio) at http://mixlr.com/eldad-tsabary or http://pdradio.listen2myradio.com/ (plan B) Check CLOrk out: CLOrk’s sounds: https://soundcloud.com/clork-1/ CLOrk’s videos: http://tinyurl.com/cl47htd Facebook event:http://www.facebook.com/events/148884571939776/ Current CLOrk members: Lyndsie Alguire, Charles Bale, Philippe Blanchette, Michaël Bresse, Joseph Browne, Stephanie Colbourn, Pasquale De Luca, Alexis Dionne, Byron Edelmann, Frankie Fiore, David Fiorentino, Christopher Gorman, Regynald Guzman, Jared Jukes, Reginald Kachanoski, Megan Keenan, Marco Antonio Liy Menor, Marguerite Luu, Ryan McNabb, Keith Odell, Michael Palumbo, Pierre Perry Pilloy, Edan Scime Stokell, Evan Stepanian, Michael Sullivan, Ryan White, Simon White, Eldad Tsabary (director)___ Pd-announce mailing list pd-annou...@iem.at http://lists.puredata.info/listinfo/pd-announce ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] [announce] [pd-fileutils] released, a command-line tool for managing pd files
Yes! It uses sink.js! But sink.js uses WebAudio API when it can. The synthesis is made in JavaScript, not in Audio API (yet!). However, I have big plans of refactoring the whole stuff to be all Web Audio API! I started `pd-fileutils` as part of this refactor : I want to separate components to make maintenance easier. But the Web Audio API version is coming, probably in 3-4 months. If somebody wanna help, they are welcome :) it's quite a lot of work for me alone.

Hi Chris, thanks for your advice. You're right, Chinese manufacturers are generally not supportive to open source, which is a pity as they are designing and producing most of the hardware today.
