@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.

nice, thanks

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!

Simply Amazing thanks!

Fantastic patches!

I can't figure out how to use the sidechain in the compressor. There's no key input, just an enelope out. Should I feed the compressor an audio signal somewhere or an envelope? I am confused. What is the sidechain preset for? Can anyone help? Thanks.

@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?

Thanks a lot! i was looking for that patch point inside the compressor for days. I would have never come out with the solution of simply putting it outside the comp without you pointing to it. Thanks again your patches are gold.

Version 0.70 is now available on deken.

I added some simple but convenient objects:

pp.amp~ a simple signal multiplier
pp.adsr~ adsr/adr envelope generator
pp.xfade~ signal crossfader
pp.shiftlfo~ a LFO that can generate irregular rhythmic patterns

pp.dynamics~ now has an option to enable feedback compression

Some parameter sliders are now colored light orange in the GUI. This indicates that the slider does not cover the full range of the parameter and is intended to encourage experimenting with values that are above or below the range of the slider.

fixed some minor bugs.

Happy patching!

I just downloaded Audiolab to get pp.spectrum~ and I love it! Thank you for making this.
