Many thanks, and sorry for the late reply.
Will download and replace.
Thanks!

These are really worldclass vanilla patches!
I started to integrate your experimental CLOP-Filter into Automatonism. Ist sounds so awesome!

@tungee worldclass.. thanks!
do you share the automatonism patch somewhere?

Is your Pdpatchrepo-Chat open,solipp?

Amazing!

this looks SICK!!! shame the project I'm working on atm is for android on mobmuplat so I'm limited to vanilla-only patches. Definitely gonna have a good look at this once I move onto the next project tho.

@liamorourke these are vanilla only (;

@solipp really? thanks

this is simply marvelous thanks so much

pushed an update to deken (v 0.3).

changes since the last version:

new objects:
pp.fft-freeze~ - a spectral freezer based on I08.pvoc.reverb.pd

pp.ladder~ - a "moog" 4th order ladder filter. I made this on out of curiosity about the "zero delay filter" design. I wouldn't recommend to use it though since we have [bob~] and cpu usage is pretty high! (except if you need a fast modulating resonant hp or bp filter for whatever reason).

pp.echo~ - an "analog" tape delay-ish delay echo effect.

pp.xycurve - draws a xy-bezier curve and reads from it. Useful for all kinds of musical gestures..

Many bugfixes and smaller changes. Be aware that some object might behave a little bit differently to the last version!

This is immense! Thanks a lot

NIcenadditions, solipp!
Could you also implement an Haas effekt?

@tungee Haas effect is already implemented in your brain, it's a psychoacoustic effect

I guess you want is a small delay between two output channels. You can do it with [pp.sdel~] samplewise delay.
something like this:

assuming you have the abstractions in your path, here is the patch:
interaural.pd

edit:
if you change the delay times over time you can get some nasty phasing effects depending on the position of your speakers. it works okay with headphones though.

Thank you very much Solipp.
Exactly what i asked for

wow this is really beautiful work!

Thank you solipp, look like a really interesting library.
I've got an error when I'll try to use it:
"audiolab: can't load library"

I thought because I'm using Pd 0.50.2 "vanilla", is it possible? Will it be available for this version?

@tabache seems like you have declared "audiolab" under File -> Preferences -> Startup.
You only need to do this for single binary libraries, e.g. zexy or GEM. Audiolab is a collection of abstractions. You can point pd to the right directory under File -> Preferences -> Path, or you can just copy the audiolab folder into your projects directory and use [declare -path ./audiolab] in your main patch.
It should still work with Pd 0.50.2, but in the future I'll incorporate any new features of pd whenever it makes sense.. you should stick with the latest version of pd, there are only benefits.

cheers!

new version up! (v 0.4)

two new objects:

pp.parameq~ - a parametric equalizer.
fancy! I guess I pushed pd-UI design to the limits with this one:

pp.butterkreuz3~ - a 3 band crossover filter with a relatively flat magnitude response. Allows you to create multiband (well, 3 band) effects.

...many fixes, changes, additions... (sorry, I'm too lazy to keep track)

Wow! Great additions!

In your audiolab plugin suite, there are a lot of nice filter implentations mostly in moog-ladder style. In case your are interested in implentation of an Oberheim-style filter:
