The Patches:

Spatialization:

Granular Spatializer: breaks an incoming stereo source into 4 or 8 grains and allocates 
each grain to to a particular output channel. In addition, each grain can be given a different 
delay and/or transposition.

Spectral Spatializer: This program uses frequency domain filtering to spatialize/animate stereo 
sound sources over 2-8 channels of playback. It does this by applying an equalization curve to 
one channel while applying the opposite curve to the opposite channel. It includes numerous 
automation controls.

Stereo-to-8 Channel Amplitude Panning Array: take a stereo source and pan each channel to 
either 4 or 8 playback channels. The panning curves used implement a square-root curve preserving 
constant power. This patch also has many automation controls.

Granular Effects:

Real-time Granular Time Expander/Contractor: acts on audio from a microphone or a prerecorded 
segment (through the 'Granularize Window'). It allows for 16 separate transpositions of the audio 
in cents and/or random units and outputs them
over 2, 4, or 8 output channels.

Granular Cloud Generator: applies synchronous and asynchronous granular synthesis techniques to form 
granular clouds (in real time) output to 2-4 channels. It allows for up to 400 grains per second and 
includes reverb, all manner of transpositions, and automation controls.

Compatibility:

The PC versions of these are Stand-a-lone MaxMSP patches. If you own MaxMSP and want to edity these on your
PC, download the MacOS9/OSX versions. All of the patches are made with the standard library of MAX/MSP externals and thus should work 
and work on Windows (XP) platforms. 
Note: Unfortunately MAX/MSP access to the CD/DVD drive is not yet supported on Windows.
