Particlechamber: a 32-voice asynchronous granular synthesizer for Pure-Data

[derek holzer <derek@xxxxxxx>]

dearest .micronauts,

how i enjoyed the last discussion on open source! i hated to light a 
fire and run away, but i was actually busy working on something. i 
humbly submit my project to the list, in hopes that it inspires further 
exploration of Pure Data and other open source + free software.

Particlechamber by Derek Holzer [Umatic.nl]

Particlechamber is a 32-voice asynchronous granular synthesizer, running 
under the Pure Data software, for real-time transformation of a 
soundfile. It is loosely based on the famous Travelizer instrument from 
Reaktor 3, however I think it's much better because it is FREE!

This patch can be used to time-stretch or -compress a soundfile,
although there are other tools which do this "nicer", but it's main 
strength is in generating clouds of sonic particles, time-scrambling a 
file, or creating abstract textures. If one does a bit of reverse 
engineering, it can also be used as a tool for learning about the 
techniques of granular synthesis. I have left a section where others can 
add their own grain-level events, such as randomized or constant-Q 
filters or windowed envelopes, to see what is possible with this 
technique. Of course, I can only highly recommend Curtis Road's amazing 
book "Microsound" for those interested in learning more.

Particlechamber runs under the Pure Data software, which can be 
installed on Linux, Win32 and MacOSX. PD can be downloaded here:
http://www.pure-data.org/downloads/

Particlechamber requires a few external objects to PD in order to run to 
its fullest potential. It uses Freeverb~ for its reverb section, and 
uses Grid as a major GUI element. [Incidentally, both of these externals 
are non-essential, and a clever soul can figure out how to live without 
them!]

It would be best to take Grid from the PD External Repository:
http://pure-data.sourceforge.net

However, Yves Degoyon's Grid external can also be found here:

The freeverb~ external can be downloaded here:

Particlechamber is free software and comes without any warrenty that it
will do ANYTHING like what I say it will. Enjoy it all the same.
