Not yet tried it myself, but what about writing live input to a table
(for instance with [tabwrite~]) in order to have access to the audio
data with message based objects? With those it should be fairly easy to
the detect the exact position of a zero crossing. For finding a single
cycle, it would be sufficient to find a positive crossing - for
instance-  and from there find the next one, so you have the exact end
points of one single cycle.

  
How would you look for zero crossings? With message based objects such 
as [until], a counter, [tabread] and comparing to zero?

Is that feasible?

(sorry for hijacking the discussion, I am curious about that)



yeah, actually that's what I thought about. I guess, one would not
compare to zero, but compare to the previous sample and check whether
the sign has changed. One could even perform linear (or even polynomial
interpolation) to find the subsample accurate location of the crossing.

Send 18 to configure an [urn]. then banging it 18 times will give you the 
numbers from 0 to 17 in random order. If you bang it one more time it will 
produce a bang that you can use to reset it with a 18.

If you actually need more than that (e.g. see the actual list of remaining 
numbers), [urn] doesn't provide that, so, you will have to make your own [urn], 
or make your own special patching around a plain [urn].

can you recode the video with less pseudo-frames ?

for example, there is an encoding setting which, when set to '8', it 
encodes one frame completely (usually as some variant of JPEG) and then 
the next 7 frames are encoded as "diffs" of some kind (codec-specific 
format). It's possible that this setting is very high, and that halving 
this setting changes the fps radically in your decoding.

Hi Peter, Alexander

We will document it more later, but very briefly first you need root  
on the device, and make sure that you have the latest version of  
Maemo 5 10.2010.19-1, then the usual ones,  
tcl8.5_8.5.8-2maemo2_armel.deb, tcl8.5-dev_8.5.8-2maemo2_armel.deb,  
tk8.5_8.5.8-1maemo1_armel.deb, tk8.5-dev_8.5.8-1maemo1_armel.deb.  
And for Alsa libasound2-dev is necessary. After that you can ./ 
configure and make  pd-0.42-5. This will at least make you run Pd  
and  for better audio, we are working on that at the moment.

Right now, Peter Brinkmann, Peter Kirn, and I are leading the  
effort,

but there have been a number of contributors as the project was
developed.  We have a nice Android/libpd app design and are now  
working
on finalizing a proper release.  The source code is available,  
break out

your Eclipse and your phone (or use the emulator) and try it out!

rjdj is on the ipad, so Pd runs on the iPad.  There are two

Pd-extended is a more powerful, but in fact less standardized

That's not a really useful comparison.  GNU without X is really

Try doing lots of list operations without list-abs on Pd-vanilla, or

Re: [PD] Using dual processor to manage 2 Pd at the same time

[Mario Mora]

Hi Joao

You can achieve that by starting one instance of pd in the usual way (for
audio process by example) and the other one using the terminal app , writing
there the adress to the app and starting it with the ./Pd-extended  command
by exampleit is recommended that you start the pd instace for video
(gem) with -noaudio flag or, alternatively desctivating the audio in the
menu of the app.

I have used that approach with success for audio and video processing in
real-time like this:
http://www.vimeo.com/12532169

hope it helps

I tried looking for a NOT object, but couldn't find one.


[==] is a NOT object. That is, it's [== 0], as 0==0 gives 1, and as 1==0
gives 0.


Moses and the 2 message boxes are as close as I can get.


With GridFlow, there is also [shunt], which is like [spigot] but has two
outlets (or any number of outlets). You can use that to make a [spigot]
and negation in a single box. (it's nearly the same as what is called
[demux] in other libraries).



Just a quick question on gridflow. Is it possible to install help files 
or something (so I can right click gridflow objects for help)? I had the 
doc folder after compiling from source, but I wasn't sure where to put it.

Hi all --

just grab the sigmund~ from vanilla and put it in your patch's directory and
it should get loaded instead of the installed version.

Re: [PD] List with variable number of floats

[Frank Barknecht]

Hi,

ah, I misunderstood you a bit: I thought, you wanted only a single slot
active all the time, never more or less. This won't be able with the
simple select-solution I provided. As Matju wrote, you either need an
urn (there is one called urne.pd in purepd, or two incompatible ones as
externals called [urn] in Cyclone and zexy).

Ciao

A brute-force approach to your problem is attached: It uses [select] to
re-trigger the random selection if you get a slot-value that already is off.
If instead you get a usable slot-value, it stores this in a [f] object
by using the cold, right inlet, so it can be switched off later, then
also updates the [select] via its right inlet to watch for the new "ON"
slot.

There is a small risk to get a lot of the same values from [random] but
this is very, very unlikely. 

You should remember the 

 [t f b]
  \/
  /\
 [f ]

idiom to delay the output of a float value by one execution step. It's
often useful, and also the use of [select] to filter out unwanted
values.

You can also do all this without storing the OFF value by transferring
the logic of switching off or on into your "slot" abstractions. The
c_tgl.pd abstractions shows how to do that. It compares an incoming
slot-number with [== $1] where $1 is the slot-id passed as argument. It
has a global receiver in it to simplify patching a bit.

Re: [PD] List with variable number of floats

[João de Brito Rocha Reis Vidigal]

Ok... I was correct... I didn't make myself clear.

Imagine I have the table (0-17).
I want to turn the ID of a random index to 1. Lets say I randomly turn 3 
indexes to 1: index 3, 7 and 14.
All good until here!!!
Now I need to turn one of these off. The issue is how do I know that these are 
the ones that have an ID 1?
The same to the other way around: How do I know that the other ones have an ID 
0?
Because I want to randomly turn to 1 one of the 0's and/or turn to 0 one of the 
1's.

If I understand you correctly, you basically need a table of the size
18. Then you can use [tabwrite] to set any of the IDs (0-17) on or off
(respectively: 1 or 0).
Use [tabread] to check the state of a certain ID.

[PD] Pd 0.42 sigmund~

[Pierre Massat]

Hi all,
I read on Miller Puckette's webpage that [sigmund~] has improved in the
latest Pd-vanilla. I use this object in my guitar patch and i have never
been fully happy with the previous version.
Does anybody know how much different and better the new sigmund~ is? I would
be glad to have a better psychoanalyst to reveal the pitch in my signal, but
my patch was made using pd-extended and i m wondering whether a
vanilla-rewrite is worth the trouble.

Send 18 to configure an [urn]. then banging it 18 times will give you the 
numbers from 0 to 17 in random order. If you bang it one more time it will 
produce a bang that you can use to reset it with a 18.


If you actually need more than that (e.g. see the actual list of remaining 
numbers), [urn] doesn't provide that, so, you will have to make your own 
[urn], or make your own special patching around a plain [urn].

Re: [PD] Bang order entry

[Matteo Sisti Sette]

I feel like I'm missing a simpler way, but this one should do the trick 
(see attachment).


The delay amount determines the maximum time that can elapse between the 
bangs of the two sensors. If a single bang is received from one sensor 
and the other doesn't arrive within that time, the "orphan" bang will be 
forgotten.


Is it what you were looking for?

As it is coming from the arduino firmata, the only way I know is that
the signal inputs a bang.
So I'll have 2 bangs being hit with a delay between them. this delay
depends on the speed of the body crossing the sensors and its size!
calling them bang1 and bang2, if the order is bang1 then bang2 = coming
in, if it is bang2 then bang1 it means coming out.
the thing is I think I have to pair the hits to set an order and I just
don't know how to pair them and read it to then bang an "in" or an "out".

If it's a list (such as (door_crossing in) or (door_crossing out))

then you could parse it down with routes

e.g.
[route door_crossing] (removes the first item in the list, if it's
door_crossing)

[sel in out] (the first two inlets will be a bang if it's in or out

 Hi again.
 Here goes another problem!

 Ok. So I'm working with Arduino firmata here...
 To expose to problem in a simple way, I have 2 sensors that are

detecting a door crossing.

 The 2 detectors give an order to the door crossing: coming in or going

out.

 Now I just don't know how I can translate that to bang 2 different

[bang( depending on if someone's comming in or going out!


 Can you help me with that!?

[PD] List with variable number of floats

[João de Brito Rocha Reis Vidigal]

Here I am again!!!

This time with a list problem! Or at least I think it's a list problem!

Here's what I wanna do:

I have 18 slot for audio and video to play. There can be one playing, none or 
even um to the 18.
These slots are to be triggered randomly.
Is there a possibility of storing the ID of the slots already triggered? Like a 
list? The thing is that if it is a list it would have to have a variable number 
of floats (wouldn't it?).
Why do I need this? Because after triggering a random slot ON I want to trigger 
a random slot OFF. So, I have to know what are the slots triggered on in order 
to trigger one of these OFF and not one 18. Otherwise I could end up triggering 
off a slot that was never on!
As well I need to know witch ones are OFF to randomly select and turn one on.

I don't know if was very clear!!! I hope so!

I remember reading somewhere that it is possible to have 2 Pd patches open

How do I do this?


Depends on what you mean by synched.

Well of course you need to run two instances of Pd as if it was two 
different programs.


If you mean using one patch (in one pd instance) for audio and the other 
(another pd instance) for video, which is i think the only solution to 
get both audio and video work well, I usually synchronize them by 
exchanging messages through [netsend]/[netreceive] pairs, via either TCP 
or UDP.


I would periodically send a packet from audio patch to video patch to 
tell it the current time. The video patch would then compare it with its 
own time. If the difference (measured in frames) is above a certain 
threshold, it would use some strategy to correct the situation in the 
least disturbing way depending on the application.


In the most simple case, you would detect if the difference in frames is 
>1 (or <-1) and you would wait or skip the necessary number of frmaes.


Depending on the application, you may need much less than that (or a bit 
more).
For example, when you have to start playing an audio and video clip at 
the same time (which may be an audio and video file or the generation of 
images and sound), you just send one message from the "master" (e.g. to 
the audio patch) to the "slave" (e.g. the video patch) so they would 
start at the same time. If the audio and videos you're playing or 
generating are short enough (few minutes) you may even not observe 
significant desynchronization. If you do, then you can resort to the 
above strategies to correct it.


All depends on the precision you need.

I usually use audio as a master and video as a slave because slightly 
affecting the speed of the video (or even skipping a frame) for 
resynching is usually much easier and more acceptable than doing the 
same on the audio side - but of course it depends.


Well I'm kind of assuming you're using GEM for the video; GEM is pretty 
good at maintaining a reliable timing; if it gets slow because of CPU 
load for a limited period of time, it tries to compensate it when it 
can, so it tends to not accumulate big errors soon.


Is this what you were talking about?

Re: [PD] Using dual processor to manage 2 Pd at the same time

[Pedro Lopes]

Then OSC will suit your perfectly (you can just use your messages through
sockets, if you don't want to use OSC, but I like it personally for many
reasons).

Just have one pd sending OSC messages to the other through a port. There's
several issues regarding serious sync, but if you feel that its do-able in
this easy way.. gor for bingo (as we say in portuguese).

Pedro

Re: [PD] Using dual processor to manage 2 Pd at the same time

I'm using OSX
I want to sync 2 PD's (not 2 PD patches). One to control sound the other to 
control video (GEM).

"(your OS can tell you in which CPU a process is running, there are several cmd

can OSX do it as well?

No, it doesn't mean that.

But all the messages and signals circulate in a since thread (on a single cpu) 
unless you use special tools to split it into several threads.

Then there is the "client process", which "own" the patch windows and the main 
window. This runs separately.

Also, [soundfiler], some GEM input/output classes, and much of PDP, can run in 
an alternate thread.

There's also the pd~ object that embeds a Pd instance within an object

I think, you mean [readsf~] and [writesf~] instead of [soundfiler] here, which
in upstream Pd is unthreaded. 

[pd~] may be worth a look to distribute load on more cores but ...

Took me a while to get this. :)

But although it answered the question, maybe Marek was instead looking for a
way to output a bang after nothing has happened for a while, like a kind of
activity meter. At least that's a common need on many occasions.

For this, [delay] is a great object because it resets the scheduled delay
whenever it receives a new bang. A simple activity monitor could look like
this:

 [r is_there_something_happing]
 |
 [bang]
 |
 [delay 1000]
 |
 [s nothing_happened_during_the_last_second!]

In OSX, the dock prevents this to happen, so, you have to go in Finder,

just after your [metro] (i assume you have one), insert a [t b b b]. With 
the right outlet, send a 1 to turn on a [spigot]. With the middle outlet 
of t, connect to your stuff that should produce a message or not. Use that 
to send a 0 to turn off the spigot. Then with the left outlet of t, send a 
bang in the spigot and see whether it goes through. It will go through 
only when nothing was received to turn off the [spigot].


for other occasions, you can swap some outlets of the [t b b b], or 
replace the [metro] by something else...

Re: [PD] Bang order entry

[João de Brito Rocha Reis Vidigal]

As it is coming from the arduino firmata, the only way I know is that the 
signal inputs a bang.
So I'll have 2 bangs being hit with a delay between them. this delay depends on 
the speed of the body crossing the sensors and its size!
calling them bang1 and bang2, if the order is bang1 then bang2 = coming in, if 
it is bang2 then bang1 it means coming out.
the thing is I think I have to pair the hits to set an order and I just don't 
know how to pair them and read it to then bang an "in" or an "out".

Ok. So I'm working with Arduino firmata here... 
To expose to problem in a simple way, I have 2 sensors that are detecting a 
door crossing.
The 2 detectors give an order to the door crossing: coming in or going out.
Now I just don't know how I can translate that to bang 2 different [bang( 
depending on if someone's comming in or going out!

Can you help me with that!?
Thanks

Re: [PD] how to set paths in Pd running on windows xp?

[Marco Donnarumma]

It might also be useful something like:

[bng]
|
[openpanel]
|
[prepend set]
|
[empty message box(


this way the path to the selected file will show up in the message box and
you'll be able to save it, re-use it dynamically, etc..

Best,

yes of course...

it could also be done this way

Sorry, this was targeted to the question about how to extract exactly
one single cycle of a recording of a periodic waveform. I don't know how
this could help in building an autotune-like patch. It might help to
build a pitch-shifter, but I rather would go for the pase-vocoder way
since I would expect much better results from it.

[PD] Using dual processor to manage 2 Pd at the same time

[João de Brito Rocha Reis Vidigal]

Hi
I remember reading somewhere that it is possible to have 2 Pd patches open 
running synched at the same time.
This would be to manage sound and video in different patches in order not to 
get (or get less) glitches in sound and video.

How do I do this?

yeah, actually that's what I thought about. I guess, one would not
compare to zero, but compare to the previous sample and check whether
the sign has changed. One could even perform linear (or even polynomial
interpolation) to find the subsample accurate location of the crossing.

How would you look for zero crossings? With message based objects such

Is that feasible?

Of course, there might be waveforms which have several zero crossings

try using slash (/) instead.

Also, it is a good strategy to have your wav files (or whatever) in
directories whose names do not contain spaces.

i am not shure either. probably you (and wikipedia) are right,
and autotune uses a phase-vocoder. using millers phase-vocoder with
small window-sizes sounds awfull though. but maybe, with
waves which are already periodic (like single cycles) it is possible
to do without windowing and short fft sizes (like 128 or even 64).
i will try this when i have found a way to extract
single-cycle waves from audio input in pd...

Re: [PD] I wanna sing like Paris

[Pierre Massat]

I have never tried autotune. I gather from what you wrote that it can be
used in realtime? It sounds a bit like the whammy pedal for a guitar to me,
because the sound is altered. I always thought the signal was split in two
parts, one used to analyse the spectrum, and one to analyse the pitch. In
this model the pitch would be modified according to some rules and the
timbre would be stamped back on it. That's what it sounds like to me, but i
may be mistaken to a great extent.

not in pd, but in reaktor and c. combining pitch-detection and a
pitchshifter (and some quantization) works quite well, and should
be not too hard to do in pd (fiddle and the pitchshifter from
the docs).
though this is quite good for subtle pitch correction, it does
not create the typical, metallic, vocoder-like "cher-effect".

maybe something like taking single-cycle-samples of the input,
when a constant pitch  is detected, and playing these instead
of the original audio would do better, but i have not tried
yet. (and i think detecting zero-crossings in pd (vanilla) is
rather difficult...)

i do not think that autotune uses fft-based methods,
since it has very little latency (and does not need too much cpu).

Re: [PD] "new wrap incompatible object" error

[Matteo Sisti Sette]

I don't know what the general solution would be, to avoid all problems 
of this kind,


but only in the very case of [wrap], IF i understands things correctly:

- zexy's wrap includes all the functionality of [wrap] and a bit more
- any patch using puredata's [wrap] would work the same if [wrap] were 
replaced with [zexy/wrap] (obviously the viceversa is _not_ rue)

- puredata's [wrap] has no advantage over zexy's wrap

So why not do the following?:

- extends puredata (vanilla) 's [wrap] so that it works like zexy's one, 
i.e. can use arguments to set range
- (not necessary for the issue being discussed, but necessary for 
consistency with puredata's usual conventions): extend both to have two 
inlets to also set the range

- suppress any warning related to [wrap]
- keep zexys/wrap, which would be _identical_ to puredata's [wrap], just 
for backward compatibility with patches written with the current Pd 
Extended in mind (i.e. people in point 3 of Claude's synopsis)



Wouldn't that eliminate all problems with wrap?
Is it undesirable for some reason?
Or not possible (perhaps for the impossibility of suppress general 
warnings in a special case?)?

be worded better, so I'm updating it.


can you make it a warn() instead, so that people can use "Find Last
Error" for things that are really Errors ? That's especially because
"Find Last Error" can really find only the Last one.



a broken wrap or pow~ is really an error in my opinion.


The timeline is important here, because I know that I (and possibly
others) have a tendency to remember things in a way that justifies my
own current viewpoint:

0. puredata had [wrap~] but not [wrap]
1. [zexy/wrap] was implemented
2. pd-extended imports -lib zexy unqualified
3. some people using pd-extended use [wrap] (from zexy)
4a. puredata implemented [wrap] that isn't quite the same
4b. puredata implemented "externals can override internals" (+warnings)
4c. pd-extended removed "externals can override internals"
5. some people write patches using [wrap] (from puredata)
6. pd-extended changes [wrap] to emit warnings
7a. puredata [wrap] users get upset about the warnings from pd-extended
7b. pd-extended [wrap] users get upset about the warnings from puredata

The point here is that, the puredata users in 5 who want to make patches
with [wrap] work with both puredata and pd-extended without
warnings/error message, now have NO options and the suggested solution
from pd-extended BREAKS puredata:

A. using plain [wrap], puredata works fine and pd-extended complains
B. using -lib zexy [wrap], puredata complains and pd-extended complains
C. using -lib zexy [zexy/wrap], puredata FAILS*, pd-extended works fine

So, given that C is not an option for most puredata users, pd-extended
should certainly not be recommending this as the way to fix patches, at
least not unconditionally (afaik in some modes -lib zexy [wrap] behaves
the same as puredata [wrap], but it can do more?)

Other solutions might be:
I. allow externals to override internals, like puredata
II. extend pd-extended's [wrap] to behave just like -lib zexy [wrap]
when zexy is loaded/imported
III. extend puredata's [wrap] to behave just like -lib zexy [wrap] and
then port the changes to pd-extended

--[[-- opinion

The pd-extended users in 3 who want to make patches with [wrap] work
with both puredata and pd-extended should have known that they were
using an extension, but sadly pd-extended's decision to load everything
automatically to "make life easier for users" caused this mess in the
first place, in the end making life harder for everybody.

The incompatible suggestion smacks of pd-embrace-and-extend...

i think i would add a slider (or better number2) for the
frequency ratios, which are fixed values in your patch.
these have great influence on the sound.

dynamicly changing the modulation depth of operators
(with envelopes, lfos, sequencers,---) could create
interessting sounds too.

using set-messages and loadbang for remembering the slider-values
is not necessary: you could just set "init" in the sliders
properties.

bis denn!

Would it be a great effort to improve the "find last error" so that you 
could then find the previous one, then the previous one and so on?


I dream of a world where you can click on any error message in the 
console and it will bring you to the source of the error...


(though before that, I dream of a world where "find last error", just as 
is, works also with GOP)

... which still can be immensely different from machine to machine, like by
library updates or by changed start-up defaults (e.g. removal/addition of
loaded libs) or by installing libraries not in pd-x (sssad, rj, ...) etc. 

Pd-extended is a more powerful, but in fact less standardized platform than
Pd-vanilla w/o externals. It's in its nature.

how have you looked for the object?

try [!=]

try "1-x"

try [select 0]

i most likely don't have time.
but the pd-extended built-in [wrap] should _only_ emit errors/warnings
if the object is used in a way that is incompatible.
creating [wrap] (pd-vanilla, or zexy; and i guess others as well), will
wrap between [0,1).
this is 100% compatible; issueing an error doesn't do any good.

the same goes for [wrap 1] or [wrap 0 1] (however, the vanilla object
will silently ignore the arguments, even though their presence might
suggest that they have a meaning; so i guess it would be ok if there was
a warning whenever arguments were used)

when [list.==] puts out a 1, I want the spigot to close (avoid

I tried looking for a NOT object, but couldn't find one. Moses and the 2

on Debian the standard vanilla+zexy install is called "apt-get install
puredata pd-zexy"

on other systems it is more like: get pd from miller's side and install,
get zexy from puredata.info and install using the provided instructions.

just because there is no one-click installer doesn't meant that there is
no standard way.

[list-compare] in the [list]-abs is a vanilla way to compare two lists.
