Hi everybody,
I'm pleased to share my new libraries : Chocolate  Coffee.

For the HOA project, I've developed a C library to facilitate the creation
of graphical objects for Pure Data and to allow further interactions with
the users. My experimentation objects were a VU-meter and a number box for
signal. They appeared useful and ergonomic for me so I undertook to extend
the list.

Quickly : Chocolate is a set of GUIs sometimes already available in PD
Vanilla, PD extented or Max with new features (like presets edition) that I
hope, you'll enjoy. And it will be a part of a more complex project for the
writting of events. Coffee is a set of objects to facilitate the patch
creation.

The libraries are available for Mac, Windows and Linux and they have been
tested on PD extented 0.43 and PD 0.45.

Download : https://github.com/pierreguillot/PdEnhanced/releases

Feedback are wellcome (for developement questions, the best is to use the
git project).

I hope you'll find this libraries useful.
Bonne année

Ps : The C library seems to work very well under Linux. So, if we don't
have problems with the other dependencies, we'll be able to offer a Linux
version of the Hoa Library very quickly.

Re: [PD] [PD-announce] Chocolate et Coffee

Hi João,

- I'll will force the size of the properties window in the next release.
Really easy but I forget to do it.
- The properties windows are auto generated with the attributes of the
objects and I plan to add new features :
sections, color picker, menu when the  possibilities are predefined (for
the font weight or for the font slant), checkbox for boolean values...
But it's not so easy to do.
- The Id name is the receive symbol (ok, it would be better to change
the label) and I will surely add a sender name.
I have to think how to do this, I want it to be generic and not complicated
to do for the developer.
- I didn't schedule to add the library to pd extented because it's already
a lot of work and I'm ashamed but I'm not very familiar with the Makefile...
And the default one seems complicated to use when you have more than one
file per object. But if someone want to help me, he's welcome !

Thanks a lot for your suggestions !
All the best,

Pierre

Re: [PD] [PD-announce] Chocolate et Coffee

The Vanilla objects have the advantage to work fine on computers with very
few memory and old graphic cards or on the hardwares like the raspberry pi.
My objects don't need the best computer but I think if I use a very old
computer I'll have some latency.
But thank you ! And for Pd-extented, I'm going to explain the architecture
of the code  on the git (that's not difficult) if this can help you to help
me.

Re: [PD] [PD-announce] Chocolate et Coffee

@Patrice : I use code::block for Linux, I think it's open source but for
Windows and Mac, I'm too many attracted by the comfort of XCode and Visual
Studio... Anyways, a good Makefile is the solution ! For GUIs, I create a
canvas in a window, the best way to clip drawing and to receive all the
modifiers, keys, etc. I'm also working an a good documentation of the code,
others developers will be able to create externals with this library.

@IOhannes : I explain in @chocolate.pd, you should be in edit mode to popup
the menu (I hope it works on your Linux distrib). If I overwrite the
classes, the users won't be able to create the vanilla object.

Thank a lot !

 properties window?
 i seem to have missed this, as whenever i right-click on e.g. [c.bang]
 it emits a bang instead of opening a properties window.
 actually the [c.bang] get's triggered with *any* mouse-click (left,
 right, middle), which i find a bit weird.
 this is on linux/amd64 with the precompiled binaries.

 if the objects were indeed drop-in replacements for the original ones,
 you could just override the class name (e.g. add a bng creator to
 [c.bang]): so everybody who loads chocolate will automatically have all
 the guis in chocolate rather than vanilla.


 finally: congrats, very beautiful!

Re: [PD] [PD-announce] HoaLibrary for PD - High Order Ambisonics Library

2013-12-29 Thread Pierre Guillot

Hi Thomas,

We thought that 10.6 for the deployment target was enough but it seems that
we were wrong. We use some dependencies to optimize the matrix
multiplications (the high order ambisonics involve a lot of computations)
and we thought that the efficiency of the optimizations depends of the
deployment target (in fact, we don't really know, we have to try). So we'll
try with 10.5 and I hope that you'll be able to use Hoa with the next
release.

All the best,
Pierre


2013/12/25 Thomas Grill g...@g.org

 Dear HoaLibrary developers,
 the library is a great project. However, trying out the Pd version on my
 OSX 10.5 machine i get errors like the following when instantiating objects:

 /Users/thomas/Library/Pd/HoaLibrary-1.0/hoa.rotate~.pd_darwin:
 dlopen(/Users/thomas/Library/Pd/HoaLibrary-1.0/hoa.rotate~.pd_darwin, 10):
 no suitable image found.  Did find:
 /Users/thomas/Library/Pd/HoaLibrary-1.0/hoa.rotate~.pd_darwin: unknown
 required load command 0x8022

 I am aware that this is caused by your library expecting a OS version
 newer than mine. Knowing from my own externals this can fairly easily be
 fixed (if there are no explicit dependencies on newer OS versions) by
 setting the OS target (SDK version) to 10.5 when building the binaries.

 thanks and all the best,
 Thomas


 2013/11/5 Pierre Guillot guillotpier...@gmail.com

 Faust is very efficient but there are particularities. We can't have a
 dynamic ambisonic order that means for each processing we have to create as
 many externals as we want orders. There's no restriction for order with
 Hoa, so it's a first problem. On another hand, GUIs are  very important and
 we can't make them with Faust. And we don't have the whole library in
 Faust. Faust is highly optimized and multi-plateform so it's useful for
 specific uses but it's not the best choice for what we want to offer with
 this Pd version. I'm going to find a solution and someone offers his help
 on codelab PD forum so perhaps Linux version will come soon.

 Cheers

 Pierre

 2013/11/5 Jaime E Oliver jaime.oliv...@gmail.com

 Doesn't Faust just do that for you? I thought you could simply export
 externals from the Faust code in Linux, but I could be remembering wrong.

 best,

 J

Hi,
I made something similar a while ago, that loops through a range of port

I believe it was pretty fast, and maybe a little simpler than your example.
I don't know of any other way to do this.

Re: [PD] audio output AND input with the Rpi?

2013-10-31 Thread Pierre Massat

Dear all,

I just took a quick look at the page on puredata.info and noticed that my
soundcard (E-mu 0404 USB) is mentioned as apparently [working]. For
clarity's sake i think it would be good to modify the page a bit so that
it's mentioned in the working soundcards. It's fully functional as far as i
can tell (it works in duplex at 44100 Hz with one input) and has been since
the beginning on the RPi without any slowing down of the USB speed. I can
even prove it with a video (http://www.youtube.com/watch?v=NwJNeouLqgQ) !
Problem is, i don't know how to edit the page...

 Hi Chris,

 I think Theron's covered most of it.

 The Behringer 222 is on the list of working devices compiled here:
 http://puredata.info/docs/raspberry-pi
 so hopefully that one should be doable, and my memory is that Andy Farnell
 has been running Turtle Beach cards during some of his workshops - stuck in
 my mind 'cos I had a Turtle Beach, old school chuckle to myself.

 If you do get them running (or not for that matter) it'd be great if you
 added your experience to the wiki page.

 For some more audio rpi tips and tweaks I heartily recommend this page:
 http://wiki.linuxaudio.org/wiki/raspberrypi
 and there's some more (related) good stuff here
 http://www.raspberrypi.org/phpBB3/viewtopic.php?p=286064#p286064

 Plus of course there's a whole heap of stuff in the pd-list archives
 (search raspberry or rpi).

 Julian

  Hey folks,

 Apologies as this post is not strictly about Pd, though Pd will be a
 crucial part of my final setup so whatever solution I find ought to work
 with Pd. Also, there is a chance the issue might lie with Pd. I just don't
 know.

 I'm looking for a usb bus-powered audio interface for the Rpi that can
 take a stereo input and provide stereo output *at the same time.*
 * *
 I have tried a couple different images and a couple different audio
 interfaces, to no avail. Perhaps there's something can be done with one of
 these setups to get it working?

 First, the Pd-LA custom Raspian (v1) image and Pd 43.2:

 ..with Behringer UCA202 (at 44100khz):

 Alsamixer picks the device up but the input section shows nothing.

 Pd (gui) audio preferences allows selection of the interface for both
 input and output. Output only is lovely and clean but as soon as the device
 is selected for audio input the audio quality drops horrendously (vaguely
 recognisable from the original signal)..
 ..although what gives me hope is I CAN software monitor the input
 (poorly) in 'Test Audio and MIDI' with this arrangement.

 ..with Behringer UCA202 (at 48000khz):

 Output only in Pd is poor (beating and popping sound - possibly sounds
 like a samp rate conversion issue).
 When device is selected as Pd input software monitoring is possible and
 oddly, though the result is still poor, there is effectively no drop in
 quality from having the device selected only for output and the monitored
 signal sounds drastically better than at 44100khz.


 ..with Turtle Beach Amigo II* (at 44100):

 Alsamixer shows both input and output and allows to change gain of
 both.
 If plugged in from boot and only the output is selected in Pd it works
 but with a lot of jitter. Selecting the device for input too causes a
 further drop in audio quality although again I can software monitor the
 input in 'Test Audio and MIDI'
 If plugged in after boot the OS crashes.


 The Satellite CCRMA (operating via ssh) and Pd-extended:

 ..with Behringer UCA202 (at 44100 and 48000):

 Alsamixer picks the device up but again the input section shows nothing.

 If I have the device plugged in from boot then I get the same behaviour
 with it as I do in Pd vanilla on the Pd-LA Raspian image, ie. software
 input monitoring but at an extremely poor quality.

 If I don't plug the device in from boot I see it in Pd audio prefs but
 get this:

 ALSA input error (snd_pcm_open

Hey again,

Possible issue:

I've installed libjack-dev and Pd builds fine - great.

I did want to have jackd2 but that doesn't have libjack-dev it has
libjack-jackd2-0.

Pd doesn't configure with jack when this lib is installed.

Does it make a difference to build Pd with libjack-dev (in effect build
with jackd1 but run with jackd2)?  I mean I guess I'll know if it's
something obvious but could there be performance issues.


Regards,

Julian

Pd seems to have built though I'm not sure if there would be some kind of
'that's it, your done, nothing to see here, move on' type message.

Anyway, when typing 'pd' on the command line I get this:

I've installed libjack-dev and Pd builds fine - great.

I did want to have jackd2 but that doesn't have libjack-dev it has
libjack-jackd2-0.

Pd doesn't configure with jack when this lib is installed.

Does it make a difference to build Pd with libjack-dev (in effect build
with jackd1 but run with jackd2)?  I mean I guess I'll know if it's
something obvious but could there be performance issues.


Regards,

Julian

you have to install libjack-dev.

a good start to install all/most packages needed to build jack (at least
with the same features as the puredata packages) is:

# aptitude build-dep puredata

Re: [PD] pix_video problem

2013-10-14 Thread Pierre Desprats


Hi,

sorry, I'm answering really slowly but I couldn't have a SDI camera 
since I posted my question.


Today I made some new tests, and guess what; it's working.

The only thing I changed is that I have 2 new devices : usb camera and 
an Osprey card for SD camera.


The blackmagic driver works only if the usb camera is connected. When I 
disconnect, I loose the signal and PD crash.


When the usb camera is plugged, everything is stable and works fine.
Mystery.

Thanks for your help, I'm sure thoses informations will be usefull 
really soon.

hello,

to reduce CPU eating, did you try to put each [pix_video] in a

this could help

I never worked with blackmagic card but it could be possible to add a

Hello,

We are using a blackmagick decklink quad on linux
to get the signal threw pix_video, we use the bmdcapture command
line tool combined with ffmpeg so as to write on a virtual video
device created by v4l2loopback (cf

http://wiki.labomedia.org/index.php/AstroFluxTechnique#bmdcapture_.7C_ffmpeg)

it works fine and it is stable even if we plug/unplug the video
sources, it allows us to capture 1080i video or PAL video
encapsulated in the SDI signal, but if we try to capture 4x1080i
signals, the framerate is less than 25fps as Pd is  100% CPU

Hello list, my first message ! youpi

Regarding Blackmagic on linux you have to use gstreamer through
pdgst.
There are two plugins decklinsrc and decklinksink, this is
working great !

I think they are in the bad plugin set

If this works the same in windows, perhaps you have to fisrt set
the mode of the blackmagic before turning gem on. By setting up I
mean selecting the appropriate input and video resolution.

And I confirm, never change settings while using it, unplugging
the blackmagic input whit gem on freezes my computer

[PD] [PD-announce] Pd Chocolate - GUI

2013-10-04 Thread Pierre Guillot

Hi,

I’m actually working on a project that aims to facilitate the creation of
GUI externals in Pd and to easily convert source code from Max to Pd and
from Pd to Max. I’ve created a small C/C++ library (at the end, it will be
a full C library) with:
- An automatic generation of border and inlets/outlets (like Max)
- A better graphics behavior (layers and functions to clip the drawings
within the box boundaries) (like Max)
- Attributes (size, value, whatever you want) that are saved with the patch
(like Max)
- Dynamic inlets/outlets (like Max…)
- An easy management of mouse motion and keys
- Macros to convert from Max to Pd and from Pd to Max

So, here the git of the project :

https://github.com/pierreguillot/PdEnhanced.git

You can find Mac examples in the Pd Chocolate folder, a small set of
externals that is not essential, unlike Pd vanilla, but that can be useful
(there’re a vu~ and a nbx~ that don’t have the blink effect of their
homologue). You will also find a library, much more substantial with many
quite complex GUIs dedicated to ambisonics on the git project HOA where the
codes are almost similar to those used in Max:

http://www.mshparisnord.fr/hoalibrary/

https://github.com/CICM/HoaLibrary.git

As you can guess, I would like to get feedbacks and advises.

The things I want to improve are:
- the automatic creation of the properties window based on the attributes
- a better captation of mouse events (right click in run mode for example)
- creation of object in a sort of « canvas » or « window » like popmenu or
entry (I want to use the clip functions of tcl/tk)

So, if you want to participate to this project, you are welcome and if you
have externals that you want to convert from Max to Pd or from Pd to Max, i
can help you.

Sorry if you have already seen this topic on one of the puredata forum but
I don't want to miss a potential helper.

Best,

Pierre

Re: [PD] Weird bug in pd-extended and Ubuntu

2013-10-02 Thread Pierre Massat

Hi,
Thanks for the clue. Turns out that the fix you propose doesn't work for
the current LTS version of Ubuntu (which is 12.04), but i've found a fix
that seems to work (from this page in French).
For the record, in a real terminal (no X), type :

sudo service lightdm stop
sudo X -configure
sudo cp ~/xorg.conf.new /etc/X11/xorg.conf
sudo service lightdm start

Then edit /etc/X11/xorg.conf (sudo nano /etc/X11/xorg.conf for instance)
by writing intel as the Driver in the Device section.

Reboot, and it works (I haven't tested it thoroughly but at least I can now add

new objects to my patch).

Cheers,

Pierre.

[PD] pix_video problem

2013-09-26 Thread Pierre Desprats


Hi,

I'm having trouble with pix_video.

I'm using a sony PWM200 in 720p/50p,
A BlackMagic Decklink Studio with HD-SDI input connected in PCIe.

I'm testing on a windows 7 with Pure data 0.43.4 and GEM 0.93.3

Drivers are correctly installed and when I send enumerate to 
pix_video, it shows me two devices :

Blackmagic WDM Capture Directshow
Decklink Video Capture Directshow

but when I choose one (it doesn't matter which one), i got the error : 
could not start graph playback, hr 0x80070057

Slightly after, pd crash.

I certainly miss clues to understand what's happening so I hope someone 
could light me up ?


Thx.

[PD] Read from and write to an array at once (?!?)

2013-08-03 Thread Pierre Massat

Dear list,

I feel very happy and pretty stupid at the same time. I've been trying to
make a simple sound-on-sound looper for a while now. I've search on the
web but i haven't any really convincing. Most what i've found was
complaints about the fact that it was difficult to achieve with tables, and
that delay lines couldn't be flushed.

Well, I just discovered that it was actually possible to read from and
write to the same array at the same time. I thought it was impossible (i'd
never even tried, to be honest). So here's my (probably stupid) question :
is this a feature ?
If it is that could probably explain why I didn't find much about loopers
in Pd, since it is very straightforward.

 Yes, it works fine due to the topological sort of the DSP graph into a
 DSP chain - but DSP is block-based, so be aware that each block is read
 as a whole before it is written - this probably only matters if you
 wanted to write to a different location for non-block-sized feedback
 effects.  Also you might have little glitchy issues when table length
 isn't an exact multiple of the block size.

 There are some examples of [tabreceive~]--stuff--[tabsend~] in the docs,
 probably in the FFT section of the manual.

 A simple looper might be a [tabplay~]--stuff--[tabwrite~] thing with the
 tabplay~ and tabwrite~ both triggered from the same source, and
 retriggerd by the tabplay~ done bang...

  If it is that could probably explain why I didn't find much about loopers
  in Pd, since it is very straightforward.

Re: [PD] Preferences weirdness in Pd 43.1 ( 2?) in RPi

2013-07-10 Thread Pierre Massat

Hi Julian,

[import] is installed, but doesn't work with some libraries. Adding the
name of the library explicitely in front of the object name doesn't solve
the issue either.
Thanks for the tip about the root user's preferences. I solved my problem
by launching pd as a regular user from rc.local (using su user-c 'pd...').
Cheers,

Pierre.


2013/7/9 Julian Brooks jbee...@gmail.com

 Hey Pierre,

 [import] isn't a vanilla object so may not be installed on the pi?  I
 think it's in the repo's though.

 When you start as root it has it's own version of.pdsettings so the
 preferences will be different.  To have matching settings between root and
 regular user just copy one of the .pdsettings to the other's home folder.

 Obviously not an ideal solution (ie dirty hack) but as long as your libs
 are in the search path [zexy/limiter~], for example, should always work.

 Regards,

 Julian

Some libraries included in the extra folder just won't load (like pduino

Also I can't add some paths, like  ...pd/docs/3.audio.examples (because i
need the reverb abstraction). Pd just won't save the path no matter what.

Re: [PD] Sampler buffer?

Hi,
You can load all your samples when loading the patch in different tables,
and then dynamically set the table (sample) you want to read by sending
[set nameofthetable( to your tabread object. If you don't do that then
everytime you load a sample it takes a while to copy it to RAM before Pd
can read it, especially if the sample is long.

Pierre.

 lots of samplers. I actually use soundfiler and tabread but anytime i open

 this problem?

works just fine but I wanted to test out (though didn't end up making use

I got the power supply from here:

The soundcard I've been using the most (ESI UDJ - thanks Antoine:) has no

the imic running duplex (with usb-slowdown) and had been getting reasonable
results (10-12ms) but running pretty light patches. Sorry can't be more

Have you tried it with full duplex with your soundcard yet ? What
latency are you getting (I can't get below 15 ms in Raspbian with some fft

Also is this think about the power supply true ? They mention it too on
the Satellite CCRMA webpage. Where can I buy a power cable that outputs 5.2

That's a lot of questions but you made me curious (and hopeful again) !

2013/7/3 Julian Brooks jbee...@gmail.com

I'm having good results from using a much leaner install - it's called
Mobius:
http://moebiuslinux.sourceforge.net/

Obviously depends on your usage but I'm ssh'ing into the pi and works
great. The minimal install seems to help with overclocking too so I reckon
I'm getting about another 35-40% out of the pi.

The main project I've been working on has a pmpd patch that the regular
raspbian wouldn't even run, on top of that I'm driving a couple of sensors
(thanks Martin:), audio synthesis, got a reasonably complex quad
spacialisation patch (thanks Lorenzo:) and is driving a 6 channel
soundcard. This is without the usb-slowdown option.

Obviously it's pushing the Pi right up to the limit but it runs*
just*about stably.

What I do think made a significant difference was switching the power
cable to one that outputs 5.2v so by the time it gets to the pi it's a
solid 5v.

 Hi all,

 I did a fresh install of Raspbian using the NOOBS installer. The
 pd-extended package from puredata.info doesn't work with my soundcard (it
 wasn't working before). And Pd vanilla installed from the Raspbian
 repositories doesn't work with it either (although it was working fine
 before). My soundcard is an old EMU 0404 USB. By doesn't work I mean that
 it either throws an Audio stuck/closing audio error, or simply freezes
 everything (Pd, LXDE, mouse, everything) and all I can do is unplug the
 power chord.

 So for me not only did it not fix anything, but i'm actually worse off and
 left with the inability to use Pd at all on my Pi.

 I haven't tried Miller's compiled version of Vanilla yet (I still don't
 know how it is different from the one available in the Raspbian repos). The
 recent Planet CCRMA Satelite for the RPi is also an option.

2013-07-03 Thread Pierre Massat

Hi Julian,
This Moebius distro looks very interesting. Can you please tell us how you
installed Pd ? From the Raspbian repos ?
Have you tried it with full duplex with your soundcard yet ? What latency
are you getting (I can't get below 15 ms in Raspbian with some fft in my
patch) ?

Also is this think about the power supply true ? They mention it too on the
Satellite CCRMA webpage. Where can I buy a power cable that outputs 5.2 V ?
I'm currently using a samsung smartphone charger.

That's a lot of questions but you made me curious (and hopeful again) !

Cheers,

Pierre.

2013/7/3 Julian Brooks jbee...@gmail.com

I'm having good results from using a much leaner install - it's called
Mobius:
http://moebiuslinux.sourceforge.net/

Obviously depends on your usage but I'm ssh'ing into the pi and works
great. The minimal install seems to help with overclocking too so I reckon
I'm getting about another 35-40% out of the pi.

Obviously it's pushing the Pi right up to the limit but it runs* just*about
stably.

What I do think made a significant difference was switching the power
cable to one that outputs 5.2v so by the time it gets to the pi it's a
solid 5v.

[PD] How to make a looper ?

2013-06-27 Thread Pierre Massat

Dear list,

i've been working on a simple looper (the sound on sound thing, Eno 
Fripp, Eno all by himself, you know what I mean). I decided to use two
tables, write to T1 while reading T2, and write to T2 while reading T1,
adding the input and the currently playing table together before writing.

I'm faced with two issues. One is a click I hear everytime I record a new
piece of sound (I m almost certain it happens while switching from one
table to the other), and another is final volume.

What is the proper way of reading two tables continuously and alternatively
? And conversely, what is the proper way of writing continuously to two
tables alternatively ? I'm currently using threshold~.

About the final volume, the problem is that the first sound i record gets
burried in the later recordings, and it all ends up distorting because it
too loud in the end. I suppose I should use a limiter on the input, and
maybe compress the output. Is that correct ? Can someone point me to a good
compressor/limiter in Pd ?

Or maybe there's a much better way to make a looper in Pd...

Cheers,

Pierre.

Re: [PD] batteries for audio cards

2013-04-26 Thread Pierre-Olivier Boulant


Same here!

I'm just concerned some Li-ion/Li-po batteries do not have an 
over-discharge protection and this could be an issue if you try to 
recharge a Li* battery that's been drained beyond its inversion voltage. 
Ask Boeing about this... ;)
I doubt this has been included in the RME sound cards since they are 
built to take almost any kind of low voltage power (AC and DC).


http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries



Over-discharging Lithium-ion

Li-ion should never be discharged too low, and there are several 
safeguards to prevent this from happening. The equipment cuts off when 
the battery discharges to about 3.0V/cell, stopping the current flow. 
If the discharge continues to about 2.70V/cell or lower, the battery’s 
protection circuit puts the battery into a sleep mode. This renders 
the pack unserviceable and a recharge with most chargers is not 
possible. To prevent a battery from falling asleep, apply a partial 
charge before a long storage period.


Battery manufacturers ship batteries with a 40 percent charge. The low 
charge state reduces aging-related stress while allowing some 
self-discharge during storage. To minimize the current flow for the 
protection circuit before the battery is sold, advanced Li-ion packs 
feature a sleep mode that disables the protection circuit until 
activated by a brief charge or discharge. Once engaged, the battery 
remains operational and the on state can no longer be switched back to 
the standby mode.


Do not recharge lithium-ion if a cell has stayed at or below 1.5V for 
more than a week. Copper shunts may have formed inside the cells that 
can lead to a partial or total electrical short. If recharged, the 
cells might become unstable, causing excessive heat or showing other 
anomalies. Li-ion packs that have been under stress are more sensitive 
to mechanical abuse, such as vibration, dropping and exposure to heat.




You need to make sure you have an over-discharge protection that cuts 
off the power when reaching about 3.2V per cell (3 cell would be between 
9.0V and 9.6V). I'm not sure I have this in the pack I use... :/


Some more detail to read when you've set your bedroom on fire ;)
http://www.nfpa.org/assets/files/pdf/research/rflithiumionbatterieshazard.pdf


Lead batteries don't like being over-drained either. It's just not as 
dangerous to recharge a Pb that's been drained too much.


Hope this helps.
Cheers

  Hi list

 Looking for a way to control video playback on the Raspberry Pi outside
 Gem's realm, i stumbled across omxplayer and this 
 topichttp://www.raspberrypi.org/phpBB3/viewtopic.php?f=38t=7987
 .

 So based on it i've made a very crude [shell]-based omxplayer controller
 in Pd, see attached. As omxplayer can be controlled via keystrokes, you can
 expand this patch's possibilities very easily. For now, you can choose a
 file, play it, pause and resume, restart the video, quit omxplayer,
 increase and decrease volume.

 I encounter an annoying bug when restarting a video : one can briefly see
 what's behind the window, be it a console or lxde's desktop. Happily,
 omxplayer has also a counter-bug thats prevents the desktop to refresh
 itself (it stays black : you have to move the mouse all over the screen to
 refresh). So to keep the restart prettier, you have to launch the desktop
 manager.

Re: [PD] wireless audio from Pd to PA system (katja)

2013-03-06 Thread Pierre-Olivier Boulant

Hi Katja,

Regarding all this with...
Digital clocks need to be synchronized to work together or else you will
get clicks. As you have said it can be done in a driver or it can be
done on-chip if your hardware has that feature. It does indeed add to
the latency. On pro sound cards you would find word clock to sync cards
together or possibly time code input/output for synchronising with video
cameras. Consumer hardware does not have these features since most
people wouldn't have any use for this. Some equipment can hold a very
stable clock even after being disconnected from the others. This feature
comes with added costs.
Super expensive digital radio mics have a noticeable latency even though
they are highly specialised equipment built to minimise this very
latency. It's about 3ms for a good setup.
Anyhow the lowest latency you will find is using analog wireless packs.
The only point of digital radio mics is Hollywood can't probably cope
with non-encrypted dialogues of your favourite TV series during the shoot.
Don't go for the cheapest, and you might not need the high end. You can
rent that stuff if it's not needed for such a long time.
The Sennheiser e100 (gen3) is pretty decent for the price. That would be
about 450~500€ for a kit.

There is a pro level audio-over-ethernet distribution system called
ethersound. It's proprietary, but worth looking into. As with other
digital format, there is a master clock somewhere in the system to which
every one syncs. Once again digital converters are the main culprits
when it comes to latency.

Netjack docs look promising. It binds Jack clients on the transmitter
computer (called 'slave') to the sample clock on the receiver computer
('master'). Netjack supports transmission over wifi, and over internet
(using the CELT codec). It is primarily designed for 'distributed
music'. Here is a paper introducing Netjack:

http://www.google.nl/url?q=http://lac.linuxaudio.org/2009/cdm/Saturday/22_Hohn/22.pdfsa=Uei=0AM3UajlJIfAO5qDgIgFved=0CDgQFjAJusg=AFQjCNF47yIrp3T6cuIXCKhl0AUIaeiA2w

For anyone using Pd on a mobile device as sound generator, Netjack
could be a great way to deliver audio over wifi. For my purpose
though, I still need access to the sound card at the transmitter side
to capture audio from a mic. An audio rate conversion routine called
AlsaInOut is provided with Netjack so you can use the slave's sound
card for playback. However, this can not be used for capturing or
monitoring, due to large processing delay. So, clock drift is the show
stopper here.

Clock drift is not related to network transmission but to the slight
differences in clock speeds of sound cards even if they are set to the
same nominal sample rate. It also happens with two sound cards used
together on one computer, like when using an USB mic for input and the
system sound card for output. Core Audio can handle such a setup, but
at the expense of increased and fluctuating latency. Jack can combine
soundcards, but buffer under- or overruns are audible.

What is so hard about compensating clock drift? If it must be done in
a theoretically correct way, pitch should not change so it will be a
time stretching routine which will indeed introduce considerable
latency. However, clock speeds often differ by a very small amount,
like a factor 1/1000 or less. What if we just accept the pitch
difference? You would get playback speeds like 1.001 or 0.999,
perfectly acceptable for my purpose at least. This would greatly
simplify the task of resampling.

Hi,

Netjack is a Realtime Audio Transport over a generic IP Network. It is

When you transport Audio Signals over a Network, you will always have
the problem, that two Computers are bound to two different Sample
Clocks. The other Network Transports face the Problem of compensating
for the drift between these Sample Clocks. This is very hard to do.

NetJack works around this problem, by syncing all Clients to one
Soundcard. So there will be no resampling or glitches in the whole
network. Packet loss is now also handled gracefully. By using the celt

Hi,

I have a rather old pair of Sennheiser e500 wireless systems (ENG type, 
portable on both ends). On the transmitter, there is an option for line 
level. I guess the newer versions keep that option. At least this does 
work for balanced line levels with the appropriate cable and the 
gain/sensitivity set to its lowest setting.

It's rather common to use wireless between an ENG mixer and a camera.

Thanks everyone for your answers.

The case is unconventional because a stereo line signal must be sent 
from the computer. Professional wireless systems assume mic or 
instrument. Consumer systems do transmit stereo signal, but without 
bothering too much about latency.


Frankly, I did not expect the difficulty to find a good solution. 
Initially I wanted the wearable computer for a music video which is to 
be recorded live with sounds from natural objects. I bought the FM 
transmitter so my cameraman will be able to hear the music while he's 
filming. For this purpose it is ideal. Then I thought it would be good 
to use the computer in it's wearable mode for public performance. I 
figured that one of the many wireless solutions would suit the 
purpose, but didn't reckon with the unusual requirements.


Further searching brought me to a new technology 'PurePath' from Texas 
Instruments. It has a range comparable with WiFi (30m), while it seems 
to work with paired devices as in Bluetooth. I haven't seen consumer 
products with this technology, but development kits are available. A 
rather convincing demo is here:

If this system can work with low latency it could be perfect for 
wireless Pd.

For a wearable live performance computer, I am looking into the
options of sending wireless audio from Pd to a PA sound system and
other listeners.

In a first experiment I've tried a Linex FM transmitter. Audio
quality
is good enough, and FM transmitters do not introduce latency. This
option is cheap and flexible, as the signal can be received by
simple
radio's, which are even built into cell phones and media
players. I
would need to boost the transmission a bit to make it more
reliable.
This will of course make the equipment illegal. Even then, the
risk
that someone else is transmitting a stronger signal on the
channel can
not be excluded.

Another option could be to send audio over Wifi. This would
require
WLAN to be available, and one extra computer (with audio
interface) as
a receiver. To avoid extra latency the audio should be sent
uncompressed, like [udpsend~] / [udpreceive~] can do it. This
has the
risk of packet loss and serious dropouts.

I've been searching for 2.4 GHz wireless music receivers and found
things like this:
http://www.sitecom.com/en/wireless-music-streamer/wl-061/p/203. They
seem to act like external soundcards for your computer. In Linux
though I've never managed to properly connect multiple
soundcards with
Pd (in OSX it's easy using the Aggregate Device Editor from
Audio MIDI
Setup). Also I guess these devices introduce huge latency.

Hi,

What raspbian package ? In the non-free repo ?
I tried pd-iemlib before adding the non-free source to the list and
apt-get didn't find it.

Re: [PD] IEM lib in Debian ?

Sorry, i don't think i got you.
Like I said I tried pd-extended yesterday and it didn't really work. You
said it could be because of GEM and pdp, so i'll try without these libs
later on.
But right now I have vanilla (0.43.2), and it's working fine, and i need
the pd-iemlib library. It is not available from the standard raspbian
repo.

Can I get only this library ? Or is pd-extended the only option ?

Re: [PD] Feedback : pd-extended on the Pi

Hi Hans,

I've installed pd-extended 0.43.4 from the apt.puredata.info repo. I tried
running it with the -noprefs flag as you suggested.
I works with alsa (i have just made a simple patch with an oscillator), but
crashes with my soundcard (E-MU 0404 USB), which works fine with Vanilla
0.43.2.

Cheers,

Pierre.

this:

way I can give it back to puredata ?

 You can use that library from pd-extended with vanilla.  This should do it:

 sudo apt-get install puredata-import pd-libdir
 cd /usr/lib/pd/extra
 sudo ln -s ../../pd-extended/extra/iemlib

 Then in your patch:

 [import iemlib]

Hi,

I just found this : http://www.openmusiclabs.com/projects/codec-shield/
Apparently the latest revision of the Pi has GPIO pins specifically for I²S
(http://www.raspberrypi.org/archives/1929 , see Additional I/O expansion).
Though i can't find anything on the web right now, it should be possible to
connect this codec to the Pi, what do you think ?

[PD] IR reverb and partconv~

2013-02-17 Thread Pierre Massat

Hello,

While readin Katja's website i discovered the [partconv~] object from Ben
Saylor's library. I had actually used it long time ago with some IR
reverbs, but I then judged the latency to big to be usable live.
I gave it another shot this morning, and realized that the partition size
could be set in [partconv~]. A lower partition size reduced the latency to
something usable, which is cool, but it also cuts the tail of the reverb
(it sounds very unnatural will low partition sizes).

Could somebody please explain to me whether it is possible to fix this
behaviour ?

 I believe there's a maximum number of partitions set in the code.  You
 could just increase the number and re-compile.

Re: [PD] Message from the boss of Raspberry Pi Foundation !

2013-02-09 Thread Pierre Massat

Hi,

Ok, so Charles Henry has been working on this, good.
Anybody else would have something to propose ? I'd love to help but my
technical background is far from sufficient. Bringing this to the attention
of the RPi foundation is about all I could do I think.

@Hardoff : the patch i'm using in the video requires 16 ms of latency,
because it uses phase vocoding. You can drop to 10 ms without it, and I
guess even lower would be possible. I use the very first version of the Pi,
with half the RAM the new model has. If we can get the GPU to compute the
audio i hope that we'll be able to get to really reasonable latencies (to
me 6 to 8 ms is really enough to play live). Also, i use the regular Pd fro
the debian repos. I can't tell you whether Miller's or Katja's version work
better.

Cheers,

Piere.

2013/2/8 Simon Iten itensi...@gmail.com

 pierre wrote in his blog that he can go as low as 10ms, later in the
 settings he writes about 16ms.

[PD] Raspberry Pi : DSP on the GPU ? (WAS : Message from the boss of Raspberry Pi Foundation !)

2013-02-09 Thread Pierre Massat

Hi again Katja,

I just read through it. Couldn't find anything about having the GPU process
some audio. It's really mostly about why it's a bad (or good) thing to keep
the GPU closed-source (at least that's what I understand [?]).

So I guess there isn't must we can do on our own to access the GPU. But
then, what can Eben and his team do about it ? I'd like to know what answer
we can give him. If he says just waiting for an application like this I
am assuming that it must have aroused his interest somehow. And I believe
that it would be great if people in the Pd community got involved. All I
can provide is some testing, but others could contribute more (if i'm not
mistaken, Miller Puckette did a great job fixing the analog out for
instance). I think we should try and play a part in the development of the
Pi. And if we're lucky we'll finally have that Pd box people have been
dreaming about for years.

Cheers,

Pierre.

Subject: [PD] GOP-GUI-dynamic patching weirdness

Hello,

I've been trying to make a copy of the Max object called
multislider. From what I gathered it's a set of sliders that
resizes itself according to the length of the list of values it receives. It was
a request posted here:
http://codelab.fr/3980
Sounds like something doable with dynamic patching!

I had to build some pack-like and unpack-like objects that I could create with a
variable number of in/out-lets respectively. That bit seems ok.

But there is some weirdness on my system. (Win 7, 64bit with Pd-extended 0.43.4
win32).
- First when I start the example patch I have no problem as long as I play with
the sliders.
But when I start to change the values of any of the numboxes, that's when
things start to look ugly. See the screen shot.
- I have patch cords supposed to be hidden that show through outside of the GOP.
I can live with that.
- More concerning I can't see the cursors moving at all. I have to open the
abstraction to have them drawn in the subpatch of the abstraction. And then once
I close the abstraction, the cursors are properly drawn in the example patch. I
can play with them or with the set of numboxes that corresponds to the current
number of sliders. Once I change set and the abstractions is resized the cursors
are set to zero and won't move.
In any case the values are still flowing through the abstractions fine, but, you
just can't see the cursors of the sliders.

Maybe mixing GOP/GUI and dynamic patching isn't such a swell idea... ;)

Anything worth reporting in the bug tracker?

Cheers
pob

  you have to adjust the noloadlib (number of libs to load) setting as
 well.
  better use the GUI to add a new library and save the settings.

 Even better would be to use [declare -lib zexy] in any patch that needs
 zexy.
  Then it'll work everywhere without editing tricks, you'll know what libs
 your
 patches need, and all sorts of other benefits.

 You can also 'apt-get install puredata-import' to use [import zexy].

Re: [PD] Pd and pulseaudio (was: ALSA output error (restart failed): Broken pipe)

2013-02-01 Thread Pierre Massat

I think I read somewhere that Romero intends to make a film about this ;)

Cheers,
Pierre.

2013/2/1 Miller Puckette m...@ucsd.edu

 
  Pulseaudio respawns itself, unless you've configured it not to. You
  can disable it temporarily with the tool pasuspender.
  The syntax would be:
  pasuspender -- pd
 
 Good to know - but even though I now theoretically know how to deal with
 this,
 the whole thing gives me the creeps - what if some update changes the
 rules and
 pulse starts re-spawning itself again?  I'll feel safer with it
 uninstalled -
 then it will have a much harder time restarting itself on my machine.

 cheers

To answer a few questions :
- I use the first commercial version of the Pi, with only 256 MB of RAM.
- There's an Arduino Uno in the pedal, with simple push buttons and pots

Congrats! Despite expressing many times how limited your time is (and

milestone. Great achievement! Impressive list of improvements, bug
fixes, new features. Many thanks to you and everyone involved.

Personally, I welcome many of your decisions like not loading libraries
per default, requiring a maintainer for each lib, removing unmaintained
libs. In my experience it was never so easy to write portable patches
between pd + libs and pd-extended. It's a huge goal to provide a
consistent experience across platforms, but from what I saw in recent
times this goal is largely satisfied. It is really comfortable to tell
people: You just need to install Pd-extended for running this patch
and they don't have to bother with any special settings or
configurations.

Keep up the good work!

 [comport] is quite thoroughly tested so I would be surprised if it is the

 It looks like a revolution to me. The effect in the second half is a
 sampler based on the phase-vocoder patch by Miller Puckette.
 I've set Pd to use a 16 ms buffer to get it to work without dropouts. It's
 a bit high but this is a demanding patch.
 I'll be documenting this on my blog, and i'd be glad to have feedback from
 you, about working/non-working audio interfaces for instance.

 Hi Pierre,

 Thank you for your kind offer.  I think I'm going to refocus my Pi
 experiments and accept that the patch I'm hoping to run is just a bit too
 meaty for the Pi atm.  So next will be to get one of my other regular Pd
 patches translated to the Pi (for an envisioned installation) and also wait
 for the next stream of Pi-like boards with just a bit more oomph.

 If you don't mind perhaps I could send you the patch for a comparison in a
 few weeks or so, if that's ok?

 Best wishes,

 Julian

 2013/1/25 Julian Brooks jbee...@gmail.com

  Hi all,

 Back to messing with my RPi after the slew of positive news recently.

 Unfortunately I'm not really hearing/seeing such good results myself.
 Certainly not getting anything like Miller and Pierre's 10ms full duplex
 from within Pd.  In fact it's still really glitchy/unstable verging on the
 unusable.

 I'm presuming that people are getting such decent results by running Pd
 headless (no gui).  Because of the patches I'm wanting to run I do need to
 have the gui so am wondering if anyone has some tips to squeeze a little
 more out the pi?

 Have updated Raspbian to most recent, done the usb tweak to 1.1, removed
 pulseaudio.

 I'm running the pi via ssh through my laptop.  I'm also running
 vncserver on the pi and xvncviewer on my debian lappy.

 Also have an imic, so don't need anything other than usb-audio.

 So things like: is it worth disabling some of the audio and midi
 modules, that kind of stuff, well you know, anything really?

 Many thanks in advance,

 Julian

 Some people seem to have result with setting lower USB speed on the

 is not due to a typo. But the order of settings may be important?

Re: [PD] Cord inspector/Magic glass thingy

Nice idea. What about having an audio output setting for this solo/PFL 
function ? That way we could specify an auxilary output and not 
interrupt the main audio stream.

That would be a sort of variable input [send~].

it'll be tricky to implement.  Not impossible though...

Let's say I have the cord inspector/magic glass thingy turned on.

For signal cords there should be a shortcut (key combo or double click)
that does the following if audio is currently turned on:
1) Fade out audio

2) Make the inspector rectangle into a hslider, with range 0 to 1, set to zero

3) ramp up audio output for the selected cord with the hslider and send it to 
the sound card

4) turn the hslider red if values outside -1, 1 appear in the signal
5) fade out and remove the hslider when the user deselects the cord
6) fade in on whatever audio was outputting originally
