crusherX-Mac! is a pure AU (Audio Unit) and VST plugin effect (VST version 2.4) with 2 inputs and 2/10 outputs (stereo version 2 outputs, surround version 10 outputs) and about 120 presets. It runs on Apple Mac Computers with Intel CPU, 1 GB, 2 GHz CPU and Mac OS X:

Requires Mac OS X v10.4 or higher.

The crusher-X algorithm is based on the traditional granular synthesis algorithm (Xenakis, Roads, Wilkins) invented in the early 1950s. In granular synthesis, short (e.g. 50 milliseconds) sound fragments, "the grains," come from a fixed file buffer. The starting time, length and silence between the grains can be modulated. More than one grain at a time is possible, so you can create complex sound "clouds" from any sound signal.
