@porres From one 5 year old to another....
A Neural Net attempts to replicate a brain..... treats snippets of language and information as if they were stored in neurons.
Starting with some instructions (rules) from a programmer it then looks for likely links between those "neurons" and builds new rules based on data matches and the probability that it will return the correct output. We don't know how the brain works, so the maths involved is somebody's best guess.
Given the high percentage of garbage LLM's scour on the net they have a quite high failure rate, which gets worse as the model grows and feeds also on garbage outputs. For a while now its language construction is excellent, causing humans to believe that far more of its output is correct than is actually the case.
Unfortunately newer models are also proving to be worse than their predecessors.

A neural net trained on a smaller data set in Pd might be better, and the initial rules easier to fathom...?

@polyplexmescalia Can be done, and probably by other means too.
Try this...... this.zip

@ben.wes Have you seen @katjav's site...?
https://www.katjaas.nl/home/home.html
There is some of her thinking on this subject in / applied tech / low latency FIR filters.
David.

@Vnms It is not easy, and I gave up myself.
If you don't mind using externals then the ggee library has objects that calculate the parameters...... for[lowpass] [equalizer] and [highpass].
David.

@FFW Yes...... well it was in Pd extended..... so maybe......
You would need to modify [mouse_region] from the HCS library.
It shows coordinates and constrains output to the mouse presence inside the GOP area.
You would need to remove the mouse click and drag constraint, using just the position so that you get bangs or coordinates only when the mouse is in the gop area.
It needs externals from PurePd and others probably.
You will be able to modify it to do what you want, and it should be more simple when done.
There will be other ways to achieve the same thing as long as you have the mouse coordinates from the window...... coordinates from the screen would not work.

@Josefo18 There was a discussion long ago..... https://forum.pdpatchrepo.info/topic/6003/rap-realtime-analysis-project where [sigmund~] and [bonk~] were mentioned.
@katjav investigated SNAC on her site...... https://www.katjaas.nl/helmholtz/helmholtz.html
... and at the bottom of that page she posted [helmholz~] which might be what you are looking for.

@ddw_music https://mitp-content-server.mit.edu/books/content/sectbyfn/books_pres_0/8375/designing_sound.zip/practical15.html has a little more description and states for [rain_on_water] .... Rain - rain on water, alternative droplet model.
But fortunately, [raindrops] is included in the tarball of all files here....... http://aspress.co.uk/sd/ so it is an omission mistake on the page you linked to....
David.

@gentleclockdivider It is replaced when a symbol...... Bug_select_or_not.pd but once created for symbols cannot become [sel float]
[select] and [route] become different objects when they are created for floats or symbols.
David.

@elden Help... Find Externals..
and search for list-abs.
As it is a library of abstractions it is not platform dependent.
David.

@elden list-abs.... here it is... list-random.zip although it is worth having the whole library.
The library consists almost totally of abstractions.
