is based on the Fourier
analysis of a complex
timbre into a series
of simple tones, each with its own amplitude and frequency characteristics.
conceives of sound as a collection or "cloud" of extremely brief sound
events or "grains" which occur with varying density and within varying
frequency ranges. In this way a kind of statistical representation of a
sound can be achieved.
work involving the granulation of sampled sound has explored techniques
of time compression and expansion as well as pitch shifting effects.
