Re: [PD] PdDroidParty: playing sound files?

[enrike]

I understand that feeling, however file playback is pretty fundamental.


sorry I guess my question should have been longer, something like: is 
there any technical reason to why there is no any example of playing a 
sound file in PdDroidParty?


I assumed there should be a technical reason, probably related to the 
way Android handles paths, to explain why there is no such an example.


As for PdParty, I have put quite a lot of work into making PdParty run 
patches as closely as possible to desktop Pd, requiring only a couple 
specific steps regarding GUIs for the same projects to run on both 
desktop and iOS. For more advanced GUIs, it's often useful to write the 
guts of a project in a patch which his then opened with 
platform-specific wrapper patches containing the GUI.


thanks for the tip

PdDroidParty cannot make as much of a promise for this regarding GUIs, 
but it does seem to handle most of the common use cases.


for me it has always worked fine both in Android and iOS

thanks

For continuous measurements, you can also calculate the RMS in the audio
domain by squaring a signal, low-passing it with a 1-pole low-pass, and
taking the square root. The period of the filter, roughly, is the analysis
window. See Zölzer's "DASP" from 2008, page 229, for more information.

Wow, crazy! Thanks for this explanation! Would be interesting to know
for what different applications this (eg a long window with short
period) can be useful. Anyway, it's very good to know.

Thanks! I mistakenly thought it was on GitHub, that's probably why I

this means that you will get a new value every 512 samples (aka 8
blocks, or 11.6ms@44.1kHz).
the value you get will take the last 1024 samples into account to
calculate the RMS.

> How would that be different from

this means that you will get a new value every 512 samples (aka 8
blocks, or 11.6ms@44.1kHz).
the value you get will take the last 512 samples into account to
calculate the RMS.

so you get the same number of values, but they use different time-frames
for doing the averaging.

Re: [PD] svn or git on github or sourceforge?

[Christof Ressi]

I'm not 100% sure about the actual state of the Pd Sourceforge repo but 
I'd dare say that almost all active Pd development by the *community* 
(i.e. issues and pull requests) happens on GitHub. The GitHub repo 
started as a mirror of the Sourceforge repo, but practically it might 
have turned into the opposite :-)


Regarding externals, there's no canonical location. For example, the IEM 
externals are actually hosted on git.iem.at, but there's a GitHub 
mirror: https://github.com/iem-projects.


There's been the idea for a central place for Pd externals 
(https://github.com/pd-externals/) but it didn't really take off (only 9 
sub repos).


IIRC, IOhannes also put all externals from Pd extended on GitHub, but I 
forgot the name and can't find it... (@IOhannes where is it again?)


BTW, I had a look at the activity on the Pd Sourceforge repo and at 
least two people still seem to use it for their externals...

[PD] env~ argument confusion

[Peter P.]

Hi,

I can't seem to understand what the second argument of [env~] is for.
The first argument is the window lenght for RMS analysis, but the second
argument is supposed to set "period in samples per analysis (window/2
default)". It seems I am getting two analysis values per window size
with the defaults of
[env~ 1024 512]
How would that be different from
[env~ 512 512]
?

Thanks for any help here!

that would be a bug in the Debian packaging.

it would be great if you could create a bug-report on the Debian BTS.

eg use 'reportbug'

trying to access the file slop-tilde.htm that is referenced in

Debian testing box with the following packages installed.

$ aptitude search puredata | grep ^i | cut -d "-" -f 1-2
