@qhr33k Thanks!

about this sidechain thing; yes you would need to feed the compressor an audio signal and use the sidechain output to let's say duck the tail of a reverb (that's just an example, you can do whatever you want with this). In this case you would multiply the 100% wet reverb with the signal from the sidechain outlet of the compressor like this:

sidechain_compression.pd

The presets are more or less didactic, you can use them as a starting point and then change the parameters until they fit your needs. In the case above you'd use the "compress" preset. I think what confuses you is the preset "Env.follow(sidechain)". This one is an envelope follower, the comment (sidechain) hints that the envelope is the signal from the sidechain outlet. Hope that makes sense?

@ddw_music

I feel a bit like the "spray everywhere" solution would require more object copy/paste -- mine just has "; next symbol instr1" where the other needs a [t], a [s], a [r], and an [f].

well, you can wrap it into a subpatch and copy/paste that : )
Essentially both methods are not complicated, they just have to be implemented in a low level language as @oid pointed out.

reading this thread, what i understand so far is this is about calling some function, store its output and retrieve it at a given point... Something like this in pd? do i miss something?
`

i made this abstraction a while ago bezier.zip. There is also an abstraction "pp.xycurve" to draw and read from 2d bezier curves in the audiolab library: https://forum.puredata.info/topic/12334/audiolab-is-now-available-on-deken

@morast did you try the pp.spat8~ mentioned above? It's an vanilla abstraction and should run in an up to date pd version on a raspberry without issues.
You can find it in the deken repos (help -> find externals -> search for audiolab)

Check it's helpfile, there is a signal controlled spread parameter. Not sure if that is what you mean by widening function.

A new version is now available on deken, v0.63.

added 2 new objects:

pp.pantd~ stereo panner with time delay
pp.grainer-mc~ a granular sampler with multi-channel signal outlet

A new example 15-train_of_sounds.pd showcases the use of some audiolab abstractions with pd's multi-channel signal connections.
Example 14-glitchfest.pd is also new and just a lot of fun to play around with.

fixed some bugs as well.

Happy patching!

@porres
It is based on this talk by Geraint Luff:

However, the basic structure is the same as in rev3~, early reflections are fed into a 16-channel fdn. Delay times are selected from a table of prime numbers. The "secret" lies in the mixdown of the 16 fdn channels to stereo. It was more or less trial and error, adding and subtracting the signals and listening what sounds good.

Sorry for not posting for some ... 2 years. Just a reminder that this project is still alive and slowly but surely evolving.
I pushed an update to deken today, v0.61. New stuff since version 0.4 include:

pp.fft-profile~ - esoteric spectral denoiser/vocoder
pp.loop.rec~ pp.loop.play~ - a pair of abstractions to record and play loops, but also useful for pitch shifting/reverse delays
pp.grainrev~ - a granular reverb, very cool
pp.phiverb~ - a good sounding reverb

many bugfixes and some new examples.

Make sure to use the latest version of pd (pd-0.55 at the time of posting).
In plugdata most objects should work but needs more testing.

@jewelzcotard sorry for the late reply, anyway if you moved the speakers in the gui, you can save with msg [save 1( to the rightmost inlet of pp.spat8~ and save the patch. A msg [recall 1( to the same inlet will load your settings.

Happy patching and make some noise!

Hi @Nullstrahler
"cd" stands for "change directory". "path/to/pd" is of course a placeholder. You have to replace it with the path to the directory you chose for the source files. Alternatively, you can use your file manager to open the directory, and then right-click -> "Open Terminal Here".

you'll need the following dependencies to compile pure data, some of them might be already installed on your system. Install with apt:

sudo apt install build-essential automake autoconf libtool gettext

sudo apt install libasound2-dev libjack-jackd2-dev

Then follow the install instructions. In a nutshell:

./autogen.sh

./configure --enable-jack

this compiles pd with jack support. you can check the configure options with
./configure --help

make

if make runs without errors, you can install with:

sudo make install

; pd-test obj 0 0 r bnag, obj 0 100 unsig~, connect 0 0 1 0; bnag bang
