Amber-X is a granular synthesis application, based upon Amber by Matt McCabe and Jennifer Bernard. Granular synthesis is a process by which sounds are broken into tiny grains or sub-sounds measured in miliseconds.
Amber-X allows users to use WAV or AIFF files to generate granular results. Users can define grain size and density, grain envelope, and several different types of grain generation algorithms among other things. Grain size and density can be defined with initial and final values, or with graphs.
