my "audiolab" abstraction library is now available on deken. You'll need Pd-0.50 or later to run this.
Please report any bugs on github: https://github.com/solipd/AudioLab

here is a picture to draw you in (:

Edit:
list of objects:

Soundfle processing
pp.sfplayer~ ... variable-speed soundfile player
pp.grainer~ ... granular sampler
pp.fft-stretch~ ... pvoc time stretching & pitch shifting

Spatialization
pp.pan~ ... constant power stereo panning
pp.midside~ ... mid-side panning
pp. spat8~ ... 8-channel distance based amplitude panning
pp.doppler~ ... doppler effect, damping & amplitude modulation
pp.dopplerxy~ ... xy doppler effect

Effects
pp.freqshift~ ... ssb frequency shifter
pp.pitchshift~ ... pitch shifter
pp.eqfilter~ ... eq-filter (lowpass, highpass, resonant, bandpass, notch, peaking, lowshelf, highshelf or allpass)
pp.vcfilter~ ... signal controlled filter (lowpass, highpass, resonant)
pp.clop~ ... experimental comb-lop-filter
pp.ladder~ ... moogish filter
pp.dynamics~ ... compressor / expander
pp.env~ ... simple envelope follower
pp.graindelay~ ... granular delay
pp.rev~ ... fdn-reverberator based on rev3~
pp.twisted-delays~ ... multipurpose twisted delay-thing
pp.shepphaser~ ... shepard tone-like phaser effect
pp.echo~ ... "analog" delay

Spectral processing
pp.fft-block~ ... audio block delay
pp.fft-split~ ... spectral splitter
pp.fft-gate~ ... spectral gate
pp.fft-pitchshift~ ... pvoc based pitchshifter
pp.fft-timbre~ ... spectral bin-reordering
pp.fft-partconv~ ... partitioned low latency convolution
pp.fft-freeze~ ... spectral freezer

Misc.
pp.in~ .... mic. input
pp.out~ ... stereo output & soundfile recorder
pp.out-8~ ... 8 channel output & soundfile recorder
pp.sdel~ ... samplewise delay
pp.lfnoise~ ... low frequency noise generator
pp.spectrum~ ... spectrum analyser
pp.xycurve

Amazing, thanks got it working! Always learning something new...

I'd like to use pp.fft-partconv~ on a long impulse response but I get the message "pp.fft-partconv-st~: IR length exceeds buffer". Do either of the creation arguments control the buffer length? Sorry for my laziness.

edit: OMG I am so lazy, what is my problem? It took 30 mins to find the answer, here's how:

• use text editor to search pp.fft-part*.* for the error message

• find subpatch that prints the message

• look at the condition that makes it print

• trace backwards on some of the receives that could make the condition true, e.g. $0-nparts

• notice that one factor in $0-nparts is $0-max-blocksize. Gee, that happens to resemble the name of one of the creation arguments.

• try it. Bingo!

this is such a great collection, thank you for sharing with all of us

i'm fairly new to Pd, was wondering how difficult it might be to create a 7.1 preset in the spat8 patch? (ie Front L, C, R. Side L R. Rear L R, and sub?)

I tried just moving the speakers into position which worked but when I save and re-open it reverts to octophonic.

Any guidance will be greatly appreciated, thank you.

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!

pp.phiverb~

what can you tell us about this new object? Where is the model from, what is it based on? I'm interested in reverb design

thanks

@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!
