or give [random] a seed, so it will generate the sme PRN-sequence in
each frame. change the seed whenever you want to change the scattering.
(afair, this is also in the examples)


oh, and don't use [repeat]; instead of [until]+[gemlist], which doesn't
require zexy at all (only Pd-vanilla+Gem)

[PD] why overlaps affect frequency of [osc~]?

[Alexandre Torres Porres]

Howdy, ever tried to compute a hann window inside a subpatch where the FFT
is happening?

And then if you're overlapping it by 4, do you see that only 1/4 of the
cycle from [osc~] came up?

That means the [osc~] frequency was 1/4 what it should be...

Now, why and how does it happen? I just have no clue at all.

Cheers
Thanks

Re: [PD] Connect Bluetooth devices

[sebaroc...@gmail.com]

Thanks for your answer Martin.

When i create comport object i receive this error:

[comport] ** ERROR ** could not get termios-structure of device /dev/ttyS0
[comport] opening serial port 0 failed!

I connected my phone using bluetooth, started transferring a file and in
that moment sent the [devices] message to comport, what i got in the
console was:
*[comport]: available serial ports:*

Any ideas? I just need to detect the bluetooth device and get the signal
strength...

Thanks you!!

Re: [PD] spectral mapping, anyone?

[Eran Sachs]

Peiman, It works great! I've been messing various sounds all day now, plus 
there's a thing in my computer with Barry Vercoe's name on it which I find 
oddly elevating.However, if I understand the wrap function correctly, it 
substitutes bin values for values of other bins through whatever function you 
apply. But the bins are still all derived from the FFT procedure. Or am I 
missing something there?
What I would like to do is to move from bins to partials, so that they are 
essentially mapped to harmonic overtones of a given fundamental according to 
nearest match. Like a clever phase-vocoder Autotune of some kind. 
Is there a way to do that, to the best of anyone's knowledge? 

Much obliged,E.

With spectral warping you can do any frequency-based manipulation, depending on 
the transfer function. I have one for pd but it requires Csound to be installed 
and a couple of other externals. See attached. On an intel mac and with pd 
vanilla 4.5.3/4 this should just work out of the box as long as you have csound 
6 installed.

Thanks, this mostly does what I want.

Overall, I would like to be able to slow down the positioning of the

Is this just a limitation of using [gemlist] and [until]/[repeat]?

with simple math you can interpolate between 2 position.
interpolate_position = (X*position_2 + (1-X)*position_1)
where X vary from 0 to 1.
you can do that with both the random /seed or with table (using iem_tab)

[PD] pd-l2ork on mint olivia

[t'es in t'es bat]

Hello,
i try to get pd-l2ork work on mint 15.
It's like an ubuntu 13.04 but with many improvements
So i try installing and i get a big issue with
sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev libglew-dev
libftgl-dev libquicktime-dev
i got that error:

The following packages have unmet dependencies:
  libgl1-mesa-dev: Depends: mesa-common-dev (= 9.1.7-1ubuntu2) but will not
be installed
Depends: libgl1-mesa-glx (= 9.1.7-1ubuntu2) but 9.2.0 ~
git20131002 +9.2.2 eb55601-0ubuntu0sarvatt ~ raring must be installed
Depends: libdrm-dev (> = 2.4.24) but will not be
installed
E: Unable to correct problems, broken packages mode "keep state"

So impossible to compile.

Is there a way to get a mesa lib working ?

Does anybody succeed to use pd-l2ork works on Mint 15 ?
Some tuto somewhere ?

Re: [PD] Scatter objects using [repeat]

[Py Fave]

look into [line] help you can choose a lower time grain than the default one .
it will make things smoother

with simple math you can interpolate between 2 position.
interpolate_position = (X*position_2 + (1-X)*position_1)
where X vary from 0 to 1.

thanks Cyrille , it wil be useful to me too ...
math lessons are way back for me ...

line default grain is 20ms.
so it's perfect for 50fps rendering. (or 25 fps if you don't mind extra 
computation)
if you render at 40 fps, you should set it to 1000/40 = 25ms (so increasing it, 
not lowering)

I don't know how bluetooth works on linux but on Windows and Mac you get

Maybe if you are not actually using the port it will show up?

Re: [PD] pd-l2ork on mint olivia need advices

[Ivica Bukvic]

Hi,

This may be because Mint and possibly newer Ubuntu distros fragment
packages differently than 12.04 I use to develop pd-l2ork. Try installing
pd-l2ork using dpkg command provided on the online documentation and if you
encounter errors like the ones you listed try:

sudo apt-get -f install

Hope this helps!

BTW if anyone out there is a packaging guru and would like to improve
pd-l2ork's deb control files please do not hesitate to contact me--there
must be a better way to do this.

P.S. please note that the latest deb now requires tclxapian package that ia
not available by default on Arch and possibly other distros--we are
currently working on figuring out how to address this.

Re: [PD] spectral mapping, anyone?

[peiman khosravi]

Hello,

Yes, your description of warp is correct.

Partial detection is more tricky because often the energy in 4 or more FFT
bins amounts to one partial. So firstly, you need to derive the partials
from the FFT data, then you need to quantise the partials' frequencies.

One possible cheat would be to trace the loudest FFT-bins and then transfer
their energy to the bins whose frequencies are nearest to the harmonics of
a given fundamental.

If I'm not mistaken, at a sampling rate of 44100 and an FFT size of 4096,
the frequency of bin 10 would be calculated as (44100/4096)*10=107.66. Just
note that only FFT-size/2+1 bins are usable. That's the Nyquist frequency
(half of the sampling frequency). If you take 107.66 as your fundamental
(and zero all the bins below that) then you can do the following:

For each analysis window...
1- Detect the next FFT bin whose magnitude is above a certain threshold
2- Transfer the frequency and amplitude content of this bin to the nearest
harmonic of the fundamental. So for input bin 15 (and a fundamental
frequency of 107.66) this would be bin 20. The bin number to frequency
mapping is linear so it's easy to calculate.

Even, using fiddle~, you can get the fundamental frequency from the input
and have it change dynamically from window to window.

You're likely to get some bubbly artefacts thought, but once you have a
basic working patch you should be able to fine tune it. So you may want to
group the bins so that you transfer not just the energy in one bin but also
the bins around it. You might also want to do some averaging of the
amplitude of 6 windows or so to avoid rapidly changing values, before you
pass the signal into a threshold detector. I can do this in Csound but I'm
not that familiar with how FFT works in PD and I don't have a patch that
does this. If I get the time I might make one next weekend though and post
it here.

Hello,
same issue with :
sudo apt-get -f install libgl1-mesa-dev libglu1-mesa-dev libglew-dev
libftgl-dev libquicktime-dev
Even if i try each alone it's the same error
E: Unable to correct problems, broken packages mode "keep state"
How can i find these broken packages
Synaptic don't show anything...

thanks

that is mainly because the "sample rate" within the overlapped canvas is
higher than the sample rate outside.
(e.g. if you are doing an overlap of 2, you are in fact processing the
double amount of data in the same time, so your overlapping "sample
rate" is 88200 if the non-overlapping rate is 44100).
the same happens if you raise the "samplerate" via "upsampling".


[osc~] uses the sample-rate information (within the signal data
structure) to calculate the phase of a cosine-table lookup.

btw, there has been a long-standing feature request [1] to extend the
signal-structure to hold both overlap factor and sample-rate, so
signal-processing objects could handle upsampling and overlapping
differently.
(speaking of which, it would also be nice, if any dsp object could have
a notion of the current overlap cycle)

Ugh, just read the rest of your message. I guess we need to investigate

Re: [PD] why overlaps affect frequency of [osc~]?

[Alexandre Torres Porres]

thanks master

well, I was betting it was that, and it actually brings me to more direct
questions I should have asked before. So here they go.

Simply put: How come and why does overlapping affect the sample rate?

> the same happens if you raise the "samplerate" via "upsampling".

I guess this is what's really confusing, cause I can't seem to get it.

If you do upsampling with block, for instance, you don't get this frequency
change issue with [osc~]. It'll run the same frequency, no problem... but
overlapping will do that somehow.

Why the hell the actual upsampling does not affect it?

And does this mean that overlap of 4 and upsampling of 4x makes it really
run at 16x the sample rate?

cheers

Not sure if I got what the request was requesting.

"the parameter s->s_sr isn't defined properly, as
s->s_sr=(fs*overlap) has nothing to do with the actual sampling
interval applied to the audio data."

Is this bit just saying overlap in [block~] is done wrong and shouldn't
affect sample rate?

Cause I'd be right there with it...

Re: [PD] spectral mapping, anyone?

[Alexandre Torres Porres]

well, let me tell you how I did it, I can send some of my last work, but,
as usual, needs some cleaning up and documenting.

But basically I'm using [sigmund~], then getting "tracks" output to use all
the partial information to feed an oscillator bank for resynthesis. This is
pretty much what you can call a phase vocoder, hence you can tweak with it
and mess around with partials.

I also have a patch where you can control the partials individually and
very arbitrarily.

So, for spectral mapping, what I do is I try to map all the harmonic
relationship from partials and "detune" them according to a different
"harmonic series".

It's a lot of work getting all of the data mapped and in order, then apply
the math and stuff. It's also tricky because you need the right tuning of
[sigmund~] to get better results according to the kind of musical audio
signal that is coming through...

Anyway, anyone got a better idea than that?

I think that if you use FFT you will go crazy trying yo get this right, and
I assume that [sigmund~] does work in the best way for this and it is based
on FFT anywy (Am I right?).

Cheers

[PD] best way of plotting distribution of events in logarithmic plot

[flad chester]

Hi list, i was wondering which is the best way of plotting
distribution of events in logarithmic plot in puredata.

I have a patch that randomly triggers sound events at different
frequencies and magnitude.
I need to plot these events in a logarithmic plot( frequencies vs magnitude) .

Which is the easiest way of achieving this in pd?


cheers

the question is how you define samplerate.
a simplisitic approach simply takes the number of samples processed
within e.g. 1 second.
if you do overlap by 2, you process each incoming sample twice, so the
number of samples that passes through the object is doubled, and thus
the sample rate is doubled as well.

this however doesn't really make sense, if you use that samplerate to
calculate the period of a periodic signal, like [osc~] does.

e.g. an [osc~ 689.062] will have a period length of 64 samples (@44.1kHz).

when we do upsampling, the internal samplerate is 88.2kHz, thus the
period length is 128 samples.
when going back to the original samplesize, you need to do downsampling,
which basically means to only take every second sample (in the most
simple form), so you end up with half of the samples discarded and the
period size of 64 again.

however, with overlapping things are not as simple. the internal
samplerate is again 88.2kHz, the period length 128 samples.
but this gives us two problems:
- imagine that the blocksize was still 64 samples (both in the parent
canvas and in the reblocked (overlapped) sub-canvas). but [osc~] will
create a "continuous" signal between two calls, as it doesn't know
anything about overlapping. this is plain wrong for overlapping signals,
where the odd frames should be considered continous, and the even frames
are continuous, but not both together.
- when going back to the non-overlapping parent canvas, we again have to
reduce the number of samples by a factor-of-two. but this time the
algorithm used is to align the half-blocks and "sum" the up.
but this means, that you still have a period size of 128 samples. which
will make ~344Hz in the parent patch...(and the odd artifacts you get
from the problem #1)

hope this clears things a bit.

the statement in the feature-request/bugtracker kind of addresses this:
in Pd the signal-block's "sample rate" is not the inverse of the "actual
sampling interval" (think nyquist and the like) but "the number of
samples processed in a given time" - which simply isn't the same if you
do overlapping

I can't see how it could be any clear :D

thanks so much for the detailed explanation, really appreciate it

I finally know how overlapping is actually done behind the scenes now, cool

And yeah, objects like [osc~] should totally be aware of this matter and do
it correctly

On the other hand, I'm getting really nice and distorted wicked sounds from

Re: [PD] spectral mapping, anyone?

[Alexandre Torres Porres]

oh, and the thing about the FFTease object is that it always fits the
partials into a fixed scale. I mean the frequencies are always the same,
and the scale isn't transposed according to a continuous fundamental. Maybe
it's because it's using and dealing with the fixed bins in the FFT... not
sure. Now I'm trying to do that according to the fundamental in a more
loose and free way.

Re: [PD] pd-l2ork on mint olivia need advices

[Ivica Bukvic]

Without seeing the errors and knowing your setup it is difficult to say. If
Mint is anything like Ubuntu then you may need to enable additional
repositories. In Ubuntu they are called universe and you may possibly even
need to enable multiverse.

You may also encounter errors related to packages that are not signed or
repositories that are not signed. Assuming that you're using default
repositories this typically should not be a problem but again I don't know
what your situation is because I don't have enough information to say one
way or the other.

Hope this helps!

[PD] 96khz and metronome tempi

[Ali Momeni]

hi all,
i'm trying to run pd 45-2 on os x 10.8,
with a MobileIO 2882 audio interface set to 96khz;
when i set the sampling rate to 96khz in the PD preferences and apply,
a 'metro 1000' puts out bangs every 2seconds or so (!!!).
when i set the sampling rate back to 44.1, all is well.


my search of the archive reported lots of postings regarding writesf~ and
96khz
but i didn't come across anything about event scheduler issues.

is this problem particular to my audio interface/os/pd-version or have
others seen it?


thanks,
a

Re: [PD] Pure Data, libpd, help

[Ed Kelly]

Hello Andrei.

The Ninja Jamm patch has moved on a bit since then, but there are some things 
you should note.

1) Events can be encapsulated but audio paths cannot if you want the greatest 
efficiency from your target device (e.g. iPhone 4 - the minimum platform for 
Ninja Jamm). But try not to encapsulate below one level below the master patch, 
even for event-based subpatched, if you don't want to glitch.
2) you will probably have to write a few externals of your own if you cannot 
get the functions you need from vanilla Pd, and these need to be wrapped into 
the compilation of the app. Look at http://pdstatic.iem.at/externals-HOWTO/ for 
more info on how to write an external for Pure Data. Alternatively it is worth 
checking out the rjlib material from RJDJ at https://github.com/rjdj - v.good 
abstractions! 
I don't make the GUI for Ninja Jamm but...
3) the way a libpd patch is controlled by a GUI is by send and receive objects 
in Pd.
In my experience it is normal to make the objects in the GUI non-callback - 
i.e. if the GUI objects receive a message from Pd they do not send it back to 
Pd, but if a message is sent to the Pd patch it can send one back to the GUI.

I hope this helps.

Best wishes,
Ed

That's because your tools are too up-to-date for gridflow. That often
happens with archlinux (which I use and love).

You'll have to dig a little in the new features/conventions for the 
build chain and modify gridflow files.

Lots of people use ubuntu or debian, which are slow (sometimes 2 years)
to adopt new version of some tools.

But that's the deal with archlinux: you know what you're doing, are
you're responsible for it :).

Charlot
