[PD] phasor to square

[raul diaz]

Hi list!

I need to convert a phasor into a square wave in this way:

phasor:

  /   /  /   /   /  /
/  |/  |/  |/  |/  |/  |
  /|  /|  /|  /|  /|  /|
/  |/  |/  |/  |/  |/  |

square (2:1):
__
|  |   |  |   |
|  |   |  |   |
|  ||  ||


so, a relation HIGH:LOW holds a high or a low value (1 or 0) a indicate
number of cycles.
I need this conversion in order to make a masking, so square doesn't have to
be an audio signal necessarily (could be a number upload each phasor cycle).

What could be the best implementation for that scheme?

Saludos!

[PD] Fwd: dynamic input at mtx_tab?

[Anton Schlesiner]

Dear all,

I try to save matrixes with mtx_tab, dynamically.

[no. of col] [dyn. changing array of floats]
| |
| [l2s]
[f $1]  [symbol $2]
[pack f s]
[row $1 $2]
[mtx_tab "filename"]

This is my approach, the message-box row dumps in this way a symbol
that causes a sparse matrix error. I am searching for a solution to
get the symbol back to a list inside the row-box.

Thx for help. Anton

I'm not sure what you mean exactly expecially bi HIGH:LOW, but

[phasor]
|
[>~ 0.5]
|
[-~ 0.5]

outputs a perfect square wave, although you need [>~] from zexy for that.

Re: [PD] phasor to square

[Derek Holzer]

Hi Raul,

you will want to investigate the binary operations and mathematical 
operations for signals. In this case, you want to know when the 
[phasor~] reaches 1:

[==~]

and this will output a signal of 1 (= HIGH), otherwise a zero (= LOW). 
You can use [snapshot~] to covert this to a float. [avg~] is supposed to 
do this as well, but it doesn't do anything on my OSX  PD Extended-0.39 
installation.

Thomas Mayer's squarewave converter that he posted using [>~ 0.5] and 
[-~ 0.5] is a similar idea, giving you also HIGH and LOW values, but you 
might still need to convert to float for the next part.

Once the result of you binary operation is a float, you can use a 
counter-like structure to count the HI levels, and some other math 
operations to count (alternately 1,2 and 1). I don't have time to patch 
the whole thing myself, but hopefully you will see what I mean.

best,
d.

Re: [PD] phasor to square

[Derek Holzer]

Hi Thomas,

HIGH and LOW refer to the binary state. The square wave conversion using 
[>~ 0.5] will actually give him a square triggered at the mid point of 
the sawtooth wave, not the beginning or end, so the phase of the square 
would be 180 degrees off from the saw. I suggested to use [==~ 1] 
instead to get the peaks of the saw, and some more math to count them 
and create the ratio between the two.

best,
d.

Hi Derek!

Your approch is exactly what I need!

I didn't know the [==~] and [avg~] objects, but they make exactly what I
want.

Thanks for the suggestion!

Re: [PD] phasor to square

[hard off]

you could just make a phasor at the rate of the square wave, and use
the method thomas posted to make it square, and then use

[wrap~ 0 0.5]
|
[*~ 2]

to get the double speed phasor

 hi raul

when doing ascii art, the font and formatting you are using is critical
for the correct appearance. in order to display your aa correctly in
other people's email-client as well, choose 'plain text' instead of
'html' format and a monospace font type while typing. 


to your problem:

you could divide the phasor frequency by three, so that one period of
the phasor matches one period of your desired rectangular wave. if i
understand your drawing correctly, you want to achieve a rectangular
wave whith a 66% on-phase (and 33% off-phase). have a look at millers
example patch 3.audio.examples/J03.pulse.width.mod.pd to get an idea how
to convert a phasoor into a rectangular wave with specified on-phase.

Re: [PD] phasor to square

[raul diaz]

Thanks a lot for your suggestions!

I tried to make the mathematical comparation for phasor with [==~] and
[avg~] and then a counter in order to count phasor cycles.
But it doesn't work, it only count one. Did I make something wrong?

Attached is the example patch.

Re: [PD] phasor to square

[Roman Haefeli]

hi raul

i am still unsure about your initial problem. probably the solution is
quite simple, but maybe you need to provide some more information. would
you like to use the rectangular wave to mask the phasor wave? so that
your resulting wave would look like this  :

  /|  /|  /|  /|  /|  /|  /|  /|  /|  /|
 / | / | / | / | / | / | / | / | / | / |
/  |/  |/  |/  |/  |/  |/  |/  |/  |/  |

if your goal is  to synthesize some customized waveform, it might be
easier to do it using [vline~] (have a look at the help patch). [vline~]
lets you practically compose any waveform, that consists only of
straight ramps (it might still be possible with curves, but certainly it
would be trickier).

[PD] Total recall abstraction

[Chris McCormick]

Hi,

[s-totalrecall] is a gopified wrapper for qlist. Place [s-tr-node] in
a stream of control messages, and it will timestamp them and play them
back on request in the exact same way, whenever you want. This is good
for recording streams of midi control messages of your live set, metro
firings, or other input data which you use to control your patches.





Have fun.

Best,

Chris.

Re: [PD] phasor to square

[raul diaz]

Hi Roman!

I'm sorry for my lack of information...

I'm making a pulsar granular synthesis patch based on Curtis Roads's
Microsound ideas using a patch from nullpointer (
http://www.nullpointer.co.uk/-/pd.htm).
So, the phasor is my pulsar frequency reference, and I want to mask the
output of pulsar granular synthesizer.
In this way a 1:3 mask will allow to hear 1 of each 4 pulsar particles.
I don't really need a square wave, I prefer to obtain a number (0/1) each
phasor cycle to multiply with pulsar granular synthesize output.
But, maybe your idea could work, using directly a masked phasor to
synthesize pulsar particles, instead of mask synthesized pulsar particles.

I will try this way, but anyway i'm curious about [avg~] behaviour. What's
wrong on my "phasor-cycles-counter" patch?

Thanks for your suggestions!

Saludos!

Hi Roman, list!

Attached is my aproach to generate masked-phasor, as suggested.
But in this way I can only obtain 1 of N phasor cycles.
How could I obtain a phasor with a M:N cycles relation, like that (2:2):

  /|  /|   /|  /|   /|  /|  /|  /|   /|  /|
 / | / |  / | / |  / | / | / | / |  / | / |

This won't work, because the phasor~ may reach 1 in between samples.  In 
general, phasor~ is almost never exactly 1 (or any other value).

Use the falling edge to get timing, which is what samphold~ does.

No time to write more now...

Hi andy, I usually build the last vanilla test package,

http://crca.ucsd.edu/~msp/software.htm

  and use cvs for externals,abstractions,and extensions.

  Before, I need to install tcl-tk devel packages (you should give a try 
with tcl-tk-8.5, it's neat ;)).

  By this way I remove many reasons for pd to not be build correctly, I 
don't always get good stuff from cvs, and apt almost always provide too 
old stuff, they don't seem update often enough the PureData packets, ;D.

Re: [PD] phasor to square

[raul diaz]

Ups...I know!
My fail was to expect that phasor~ reaches a 0 value!
I agree with Roman, signal to message conversion losts accurary.
Would be better to use a masked phasor as synthesizer input, but how to
generate a masked phasor with a M:N cycles relation?
Maybe with a inverted phasor~ and samphold~?

I will try!

yo, i just had a quick look and it seems, that [avg~] currently isn't
working on my system (so isn't [tavg~], both don't give any output at
all). don't have the time to investigate that now.

the first problem is the comparison with [==~ 0]. the signal from
[phasor~] reaches practically never exactly 0, unless the frequency of
it is some integer fraction of the sampling frequency and the phase is
set accordingly. this is because the moments, where the amplitude would
reach 0, is most of the time somewhere in between two subsequent
samples, but almost never exactly at sampling time. you can check that
by writing the signal of a [phasor~ 9213] to a table and have a look at
all the amplitude values. also the output of [==~ 0] will miss most of
the cycles and almost always be 0. 

the next problem is, that [avg~] updates only every 64 samples. with
higher frequencies, [avg~] would miss some the cycles. further [avg~]
outputs a float messages, which is still a float message after [change],
which overwrites the internal value of [f ]. you cannot build a counter
that is triggered by a float. you would need a bang here. a construct
like:

[avg~]
|
[sel ]
|
[f ] etc.

would be more likely to work. 

please someone correct me, if this is totally non-sense, but my
experience is, that it is usually much easier to generate/synthesize a
signal than using some sample-level detection methods to compose it.
often a conversion from signal to message domain means loosing accuracy
because of the blocksize or at least the result is coming one block
late.

  Also if you don't use to compile with linux, use have to install the 
tools for compiling, like autoconf, automake, gcc, g++, libc, 
alsa-devel, jack-devel, don't forget to put --enable-jack --enable--alsa 
at ./configure.
  The externals dependances will come in doc files or errors during 
compilation.
  if you want to build pd-extended, you might want look at this:

http://puredata.info/docs/developer/GettingPdSource/?searchterm=rsync

I dunno about gridflow (often changing) and flext (the complete install 
is not easy, I suspect flext isn't ready for 64bit distro), but Gem is 
easy to build from it's cvs:

[PD] Math of Gem

Could someone point me to a discussion of the matrix (and other) math of 
Gem?  Particularly with respect to lighting effects (I'm already

Particularly the interactions between [world_light], [light], [ambient], 
[diffuse], [specular], [color], etc.

[PD] Ergates music video

[Chris McCormick]

Hello,

A bit of shameless self promotion:

My experimental music video 'Ergates' is up on archive.org


It was made using Ergates  (Pure
Data + Gem + a USB gamepad controller). That [s-totalrecall] patch i just
posted made it possible to capture all the gamepad & metro data in order
to do a non-realtime pix_record render. Special thanks to all the posts
in the archive about that, and sewing together jpg & mp3 files into
movies.

Enjoy!

Best,

Chris.

If only I could help, I gave a try with cygwin (using mingw compiler

  if you have downloaded externals, you can go to externals folder with 
the console and type 'make creb'. It will build a bunch of externals 
that will contain [fdn~] and [ead~], 'make ggee' should build [moog~], 
and 'make cxc' for [delta~]

Check out doc/3.audio.examples/J02.trapezoids.pd for a patch that can
make all kinds of waveforms with jumps (discontinuities) from a phasor
signal. In that patch, if the Amplitudes add up to 0 you get a waveform
with only horizontal segments.

For your 2:1 square wave, just set the amplitudes of the first two
wrap-phases to 100 and -100, and the phases to e.g. 33 and 66.

For the theory behind this technique read the final chapter in
Miller's book, e.g.
http://crca.ucsd.edu/~msp/techniques/latest/book-html/node186.html

It's actually very similar to the [vosim~] abstraction I posted a
while ago, which is also based on phasors with a silent period. The
phasors are then used to lookp a squared cosine, with additional
damping.

Hi all,

Thanks for the feedback :)

alexandre r. decoupigny wrote:
> how did you render it ?

Like this:

 mkfifo fifo.ppm
 pd -lib gridflow -open cycletile1.pd &
 cat fifo.ppm |
 ppmtoy4m -S 420mpeg2 -F 25:1 |
 mpeg2enc -f 8 -a 2 -o video.m2v

The Pd patch writes success frames in uncompressed PPM format into a 
unix FIFO (named pipe), which is sent to mpeg2enc (as above).  The patch 
also writes audio in WAV format, which I then trimmed in Audacity to be 
the same length as the video, and encoded/multiplexed like this:

 twolame -b 224 audio.wav audio.m2a
 mplex -f 8 -V -o final.mpeg video.m2v audio.m2a

Hope that helps,


Claude

Re: [PD] phasor to square

[Andy Farnell]

Yes, I noticed that. I followed it with a sin function to get 
little bursts of cycles and they have a formant like property.
With certain settings it sounds like a resonant tube. 

cheers,
Andy

[PD] Mac OS X Intel autobuilds

[bsoisoi]

Hello everyone,

Is there a reason there hasn't been an autobuild for Mac OS X x86  
since around 2007-12-07?  Do we know when we can expect the Intel  
builds to resume?

Thanks,
~Brandon

[marius schebella]

jan 17 has one.
the reason why the machine is down isvery trivial. the autobuild process 
was set up on a school machine which is in daily use by students and 
good students turn off the machine during night. Afaik the machines got 
totally reset for the beginning of the new semester (starting with 
jan22). don't know if it will be up again. hans?

[PD] Capturing Gem Video in Linux

[jim]

Hi I'm using the Ubuntu Gutsy 7.10 pd-extended and trying to get
pix_record to work with mild success. Seems to keep crashing when trying
to capture fullscreen. I've had better success with Yukon
http://dbservice.com/projects/yukon/
, though it's a bit choppy. Just curious if anyone else using this
distribution is able to get pix_record to work well at fullscreen and if
so what codec are you using ? Thanks 
Jim

Re: [PD] Mac OS X Intel autobuilds

[vade]

What machine is it hans/marius? Perhaps we can set aside an intel box  
for um, us researchers and we can leave it on :) Since I am probably  
around more than Hans is I can check on it periodically.

I believe PPC systems can compile intel builds, with 10.5, no (im not  
positive but I think you can target them??)? If so, we may have a  
spare machine for this at Poly we can put in the research area that no  
one will mess with...

Use a separator to create two gem pathways and on one of them [scaleXYZ]
to 0 in the y dimenson and expand slightly in the x and z, and then color
everything black. I have an abstraction to do this automatically but it's
a bit fiddly and doesn't always work 100% correctly. You can see that
the shadows aren't "real" if you do certain things, like their size and
position should be dependent on the height of the geom, but they aren't.
With a vertex shader it would probably be much easier to do this still
of shadow and make it look good (e.g. set the y component of verticies
to 0 and then stretch the x and z componentents depending on the
original y value).

Best,

Chris.
