If dsp is on, and you dynamically create 10 objects in one go (in zero logical time), then the dsp graph will be re-calculated 10 times. If you turn dsp off, then dynamically create 10 objects as before, then no dsp graph will be evaluated until you turn dsp on again, summing up to exactly 1 time. Furthermore, it guarantees that the entire DSP graph is calculated and not only parts of it (because of buggy implementations) Thanks a lot for those explanations. It's clear enough to see why choose these method even if internal processes in the DSP graph are still incomprehensibles. - DSP 0/1 method - Some questions --- With one audio abstraction. If we create just one audio abstraction at one time. Is it still the best solution or is it the same than other methods ? --- Audio clics.

Re: [PD] Pd-gui bug (was Re: search plugin update)
Interesting test results. It would be quite nice if Tcl/Tk handled the window placement for non-PatchWindows. Part of the problem there is that the .pd fileformat stores the location of the windows, and therefore Pd explicitly places the windows using those coordinates. That might be related here, but maybe not. As for Test 3 4, that's not Apple that properly places the patch window beneath the menubar, that's code in 'pd-gui'.

Re: [PD] arrowheads on cords plugin
Cool plugin. Although I am experiencing a weird bug: - it only draws the arrows ONCE by any event the pd window is redrawn - events that I tried and worked (thus the arrows magically appear): save patch, move patch window. change desktop. - events that do not do nothing: moving stuff inside the patch (moving an object, drawing new coords). Could be an X/ubuntu issue, maybe its just here. I have to try on other machines (anyway: Ubuntu 10.10, gnome, pd 0.43 extended latest nigthly build, your plugin was downloaded from the list, second mail you sent with the bugfix) best regards, pedro On Sat, Aug 27, 2011 at 12:23 AM, ALAN BROOKER alan.brooker2...@gmail.comwrote: cool... like this ...thanks Hans!

Re: [PD] making puredata headphone-safe
Ah, guilty as charged. Those LPC plugins don't work very well due to discuntinuities in the filter kernel across DSP block boundaries. It has been on my to-do list for a very long time to recode those objects using a different method. One way to guarantee that things will screw up is to change the number of poles rapidly. The problem is that some objects can generate unstable errors that are orders of magnitude greater than normal audio signals. Then there is a signal that maybe goes between +/- 10 rather than +/- 1, and the volume control makes little difference. Please don't ask me for specific instances - I can't remember any at the moment, but it's happened to me before. I personally do not use PD with headphones unless it is a patch I know well, with reliable outputs. Conversely, a lot of noise music created using PD is played permanently clipped to oblivion. One thing you can do is to use a limiter before the dac~. If the problem persists then avoid this plugin. The metastudio has lots of these. A limited volume control for stereo is enclosed (check the limit box, or send a [limit 1( message into the right inlet).

Re: [PD] Pd on Android
2011/8/29 Pierre Massat pimas...@gmail.com I plan on buying my very first smartphone in the next few days. I want a phone running Android since it appears to be the best platform to run Pd. I m just not quite sure about the way Pd can be used with a smartphone There's Rjdj, which basically runs pd patches without gui (calling them scenes) giving you the possibility to use the smartphone's touchscreen and accelerometer as controllers for the patches. So, you still need your pc to edit patches, but you can use them on the phone. Rjdj is for iphone, but you can download an rjdj scene player for android devices here: http://puredata.info/community/projects/software/sceneplayer or here: http://autobuild.puredata.info/pdlab/libpd/ At the second link you will also find an archive with some rjdj scenes and Pd Test, it should be something similar to scene player but honestly I couldn't understand how to use it, i can just test sound (maybe it's intended just for that?). Here are some resources on how to build pd-patches for rjdj/scene-player. From the rjdj blog: http://blog.rjdj.me/pages/pd-utilities A tutorial by mike dixon: http://blog.makezine.com/archive/2008/11/howto-hacking-rjdj-with-p.html Both are iphone-oriented, but they contain very useful informations on how to start. Other resources: Some example scenes (very good base to learn): http://download.rjdj.me/pdutils/examplescenes.zip Rjlib, a collection of useful abstractions to build your scenes, and the abstractions you need to run a scene in pure data on a pc: https://github.com/rjdj/rjlib Pd everywhere, on noisegroups. Here are some interesting discussions about this topic, like the following one: http://noisepages.com/groups/pd-everywhere/forum/topic/sceneplayer-for-android-vs-rjdjs-scene-player/ I just started to deal with this stuff, and i have still many doubts and difficulties. For example, i still couldn't understand how to download scenes from the rjdj website on my android phone, it seems you just can do this with an iphone.

I want a phone running Android since it appears to be the best platform to run Pd. I m just not quite sure about the way Pd can be used with a smartphone There's Rjdj, which basically runs pd patches without gui (calling them scenes) giving you the possibility to use the smartphone's touchscreen and accelerometer as controllers for the patches. So, you still need your pc to edit patches, but you can use them on the phone. Rjdj is for iphone, but you can download an rjdj scene player for android devices here: http://puredata.info/community/projects/software/sceneplayer or here: http://autobuild.puredata.info/pdlab/libpd/ At the second link you will also find an archive with some rjdj scenes and Pd Test, it should be something similar to scene player but honestly I couldn't understand how to use it, i can just test sound (maybe it's intended just for that?). Here are some resources on how to build pd-patches for rjdj/scene-player. The PdTest app is really just there to check whether Pd will work on your Android phone, and to let you play with a few parameters like sample rate and number of channels. For the time being, we aren't posting binaries on a regular basis. Instead of following the links above, you probably want to get the source and build the Android apps yourself in order to make sure that you have the latest version. The code is available here: https://gitorious.org/pdlib I just started to deal with this stuff, and i have still many doubts and difficulties. For example, i still couldn't understand how to download scenes from the rjdj website on my android phone, it seems you just can do this with an iphone. I hope anyone reading this thread has some useful hints :) Scene download from the RjDj website isn't implemented yet. I'm hoping to change that soon, at least for those scenes that are available free of charge. For the time being, the easiest way to install scenes is to just copy the .rj folder to your sd-card, or you can fire up the rjzserver and on your computer and then download scenes from there. (Make sure to build a recent version of the ScenePlayer; communication with rjzserver is a fairly recent addition.)

Re: [PD] Announcing CouchPdb development
Sounds interesting, do you have an application in mind? This kind of
library is best explained via an interesting example, IMHO. I'll give
some feedback inline below:
On Aug 26, 2011, at 7:00 PM, Thomas Mayer wrote:
Hello,
inspired by the great effort of Louis-Philippe with Puredis, I have
started developping a library for another of the NoSQL databases out
there, CouchDB.
CouchDB is a database with a RESTful interface, i.e. you connect to
the
database with HTTP requests and depending on the HTTP method you
perform
the operations. The data you send to CouchDB for storage and the data
you receive back from CouchDB are JSON objects, so (more or less) as a
lemma, the library also contains objects for encoding and decoding
JSON
data.
The current version is online at https://github.com/residuum/CouchPdb
A reason for developping the library is Ubuntu One, as it offers a
free
5GB space and includes a CouchDB database.
All is in an early stage of development, so do not expect anything to
work, it is still very experimental.
I mainly uploaded it to Github to discuss a few points, where I do not
know how to deal with in a manner fitting Pd, especially when it comes
to encoding and decoding JSON data:
- How should JSON data be dealt with in general? I am currently just
outputting one long symbol separated by spaces, so an object of
{id:1, name: my-name}
becomes
id 1 name my-name
but
{id:1, name: my name, year:2011}
becomes
id 1 name my name year 2011
and thus breaks the pattern of key value key value key value.
I could output this as list, which would make spaces in values not
break
the pattern of key value key value key value (really?). But is this
really a way to represent data in the correct Pd way, i.e. does this
data format fit the principle of least surprise?
How about a message per key/value pair? Then you just need to ensure
that the key does not have spaces in it, then the value can be a
symbol, float, list, etc. It is possible to generate symbols with
spaces in them in C, and you can work with them too. The problem
really is you can't save symbols with spaces to a .pd file (unless you
use DesireData)
- How should nested objects and arrays be handled? Should they be
handled at all?
That's pretty tricky... I can't think of any examples in Pd. To start
with, I say get something working with the most simple useful set of
features, then build from there. So ignore it for now, and give
guidelines as to how to format the json for Pd.
- How to implement attachments (binary files) for data? Or should I
forget about this stuff and e.g. store images as base64 encoded
strings?
I am asking this one in particular, because one application of the
object that came into my mind would be a website to upload pictures
that
are downloaded by a Pd patch in an installation in some gallery, or
multiple gallery installations worldwide uploading snapshop images and
interacting somehow.
You should look at Martin Peach's (net,osc, mrpeach lib) and Bryan
Jurish's (moocow, bytes2any, etc) work with strings. You can send
arbitrary data as lists of floats, where each float is a byte. Using
[binfile] you can write bytes to a file, using bytes2any you can
convert them to strings, and any2bytes for vice versa.
.hc
Please do not read the code ;) I have not programmed C for ~10 years,
and I have never coded anything but simple stuff for university. So
actually: Read the code and give me pointers (no pun intended) to
problematic code.
Best regards,
Thomas

I think I'm not supposed to do as such as RJDJ is an app for iphone, it's not directly related to the Sceneplayer on android (I mean rjdj didn't developp it).

Re: [PD] sending image from of / libpd
Here's the problem that it is supposed to solve: You want to translate a heterogeneous list of objects in Java into an array of type t_atom in C. That's all. Btw, did you look at Pascal Gauthier's library ? Yes, but I think it solves a different problem. In particular, I don't want to mirror t_atom on the Java side. and also, I just read your libpd_read_array and libpd_write_array functions. They don't work in 64-bit mode, in which sizeof(t_word) != sizeof(t_float). Yikes, good point. I'll look into it.

Re: [PD] Pd on Android
I have to disagree with you. iOS is a better mobile os for running applications using libpd (aka RjDJ, Nodebeat, etc) since it has a low latency audio api. Android can't give you anything better then 20ms or so. If you want to build a realtime, I'm afraid you have to stick to iOS for now ... This is why I'm targeting iOS for the upcoming robotcowboy app ... although I'd rather use a much freer platform.

Re: [PD] Pd on Android
Hey Dan, I agree, Android's downfall is the poor audio implementation on the devices. How many have you tested? Can you post that data anywhere? It would be good to start collecting this. I think there are starting to be some Android devices with solid audio performance, so it would be good to have a source of data on this. .hc On Mon, 29 Aug 2011 16:30 -0400, Dan Wilcox danomat...@gmail.com wrote: I have to disagree with you. iOS is a better mobile os for running applications using libpd (aka RjDJ, Nodebeat, etc) since it has a low latency audio api.

Re: [PD] Pd on Android
No one seems to have brought it up, but by far the most accessible way to run pd on android seems to be pddroidparty, also by Chris. It really is an install and run solution, although some slight modification of your pd patches will be necessary. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Even at lowest system volumes, it seems that Terrible Things can happen. Are there any precautions that I can take to make it feel less like I'm taking my life into my hands when I have to use headphones? Try making a [noise~] connected directly to a [dac~] and set the headphone volume so you can live with that. Nothing will ever be louder than that. Hmm, I don't think that's actually true in all cases. On a MacBook Pro running Mac OS X, I've had the volume set to one above mute, but had massive feedback from LPC patches that were very very loud. [noise~] would be very comfortable at that volume setting. I think some platforms do the output mixing in the digital domain, so my min volume would be [*~ 0.01], so that this would still make a very loud sound: [noise~] | [*~ 99] | [*~ 0.01] (i.e. the Apple output mixing) | In this particular case, the sound output actually gets shutdown entirely, so you have to reboot to get sound output again. That make no sense. How can you have two sounds at the same level going into a mixer that come out at different levels? Or do you mean that a squealing sound is perceived to be louder than white noise? Maybe you could demonstrate with a patch? Martin If it seems like magic your assumptions are wrong. Martin Peach I am taking a biologist's approach here: I've observed this happening multiple times in the wild, now I have to figure out why. Its very reproducible, I've taken the field mice into the lab and seen them reproduce ;) Take Ed Kelly's fun LPC cross-synth example, in ekext/examples/lpc-cross-synthesis.pd. Put some loud samples into it and go crazy with the parameters and... MELTDOWN! I've never heard my computer make a louder sound... I knew that this patch has some feedback aspect to it, so I was doing my standard practice, having the volume very low. Hmm - of course there is NO volume control on those headphones at all. The volume is permanently set to full. When you turn down the level for headphones on the laptop you are only dividing the digital level (which must still be a float at this stage, given your observations) by some figure so that the DAC gets lower numbers. Then if pd is putting out much higher levels than 1 they is never clipped until after! the headphone level control. The only way to keep the volume down is a limiter, compressor or clipper in your patch before [dac~], or feed pd into a limiter via jack before the headphones get it.

Re: [PD] Pd on Android
Seconding the dissatisfaction with real-time audio support on Android in general. I've only recently jumped on the android train (Samsung Droid Charge) and I've noticed that the only audio apps that are usable are of the sequencing / drum machine variety, because they don't depend so much on low-latency. Any apps where tapping on the screen is supposed to generate a sound exposes serious latency issues. I've heard that gingerbread made some changes to the available audio API, but supposedly they didn't substantially improve things. According to the people who know many of the latency issues are low-level (drivers and actual hardware limitations) that have as much to do with the device manufacturers as Android itself. One of the downsides of an open platform that runs on a wide variety of devices. I haven't had a chance to survey the situation with common audio CODECS being used on these devices and whether the drivers are available open-source, and/or could be hacked for better latency. I haven't been able to test much with libpd yet. So far any time any libpd-based app tries to access my microphone I get this crazy noise (actually sounds kind of cool, but definitely not the intended sound). I haven't tried building the latest from the repo, I didn't realize the binaries were substantially out-of-date (I didn't bother to check any timestamps). If that doesn't fix the issue I'll be sure to get in touch with the devs and see where the issue may lie. -s On Mon, Aug 29, 2011 at 4:54 PM, Hans-Christoph Steiner h...@at.or.atwrote: Hey Dan, I agree, Android's downfall is the poor audio implementation on the devices.
