Granular
Granular Synthesis is the process of creating new sounds from tiny fragments (or 'grains') of other sounds often as short as 10ms in length. These grains then get redistributed and reorganised (often offsetting the pitch of each one) and the result is interesting, unpredictable, evolving sounds with vague characteristics of the original.
This is a simple implementation of the system created in Shockwave - grain length and pitch offset can all be modified and it includes a simple modulation section. Sounds can be retrieved via its own internal search engine, so for example typing 'car' should return some kind of car sound and place it in the system. Patches which users create can be saved on the web to be shared by other users at any time.
