@dmanz sorry, I was wrong in a rush and corrected my last post now:

[t b a] not [t a b]
it is right to left order,
first set the message (anything) then bang.

@dmanz have a look at the messages-helpfile.

Commata in messages separate messages,
so

#anything here
|
[set open $1, bang( 
|
[willbeovewritten(
|
[print]

are two successive messages
[set open $1( and [bang(
same as

#anything here
|
[t b a]
||
|[set open $1(
||
[willbeoverwritten (
|
[print]

Delaying the bang with [del] breaks the deterministic order of operation!
Usually this is bad practice.
(Althought sometimes required, if you need exact timing or have to mess with other rare non-deterministic operations, such as [readsf~] loading from harddrive (Pd 0.55) f.e.)

As you have mentioned, you can compose messages with lists, too.

#anything here
|
[list prepend set]
|
[list trim]
|
[t b a]
|/
[willbeoverwritten(
|
[print]

Data type String is called Symbol in Pd.
You can cut the Symbol and List prefix / selector of a message with [list trim].

Did anyone find an ideal screen size / resolution for Pd yet?

I can not recommend:
14 inch at 1920 x 1080 with 150 % scaling in OS
15,6 inch at 1920 x 1080 with 125% scaling in OS
Either needs zoom-in and there is not much space for patching left.

Ideally the screen would sit below ear-level for great studio acoustics. But I probably have to reject this premise.

Don't know what it used to be in Extended,
but IEMlib has some [filter~], too.

I guess, the reason why we surprisingly can not find that one in Deken, is because there is no separatre .pd abstraction, nor any help-file in the lib-folder.

It is used for many different filters in IEMlib:

[moses], you can use it to filter big jumps. Maybe use feedback to dynamically adapt the right inlet.

moving-windowed-gate-help.pd
(edit:small bug fix)

@vulturev1 Use the right outlet of [sigmund~] with [>] and [spigot] to filter out "silence".
Look at [moses], you can use it to filter big jumps. Maybe use feedback to dynamically adapt the right inlet.
Also play with sigmunds window-size and hop-size.

This is a Vanilla moving average (EDIT now with [arraysum]) :

movingaverage3.pd
movingaverage3-help.pd
Moving average is a low pass and it also distorts the good data portion.
Reading your description, maybe a median filter with uneven windowsize is better suited, see this screenshot, made with else/median: https://forum.pdpatchrepo.info/topic/13849/how-to-smoothe-out-arrays/11

EDIT: Pd 0.54 Also study helpfile with -minpower, -quality, tracks ect !

Be aware of naming conventions:

A subpatch is this: [pd sub]

An abstraction is this: [abstraction] (calling another .pd file as object)

Both, abstraction and subpatch, can have graph-on-parent.

An abstraction may have arguments, such as [abstraction 1 2 3 hello]

A subpatch can not have arguments.

$0 in a subpatch is same as in it's parent patch.
$0 of an abstraction is unique.

For getting $0 of the parent patch inside of an abstraction, you can handle it as agrument, such as [abstraction $0]
and poll it inside the abstraction with $1 (first argument).

Getting $0 of an abstraction outside of the abstraction, at it's parent patch for example, is one of Pd's issues.

One way to solve this is

inside the abstraction:

[loadbang]
|
[f $0]
|
[outlet]

Here is a workshop on data structures from some years ago (things might have changed in the meantime, but I don't know). Unfortunately the workshop-patches are not online, but you might ask João in the Pd-mailinglist.

I am interested in how to pipe data from Pd to a fully equipped plotting-software?
