Silt three grades fine, medium and coarse 0.002 mm to 0.006 mm to 0.020 mm to 0.063 mm). In actuality, silt is chemically distinct from clay, and unlike clay, grains of silt are approximately the same size in all dimensions; furthermore, their size ranges overlap. Clays are formed from thin plate-shaped particles held together by electrostatic forces, so present a cohesion. Pure silts are not cohesive. According to the U.S. Department of Agriculture Soil Texture Classification system, the sand–silt distinction is made at the 0.05 mm particle size. The USDA system has been adopted by the Food and Agriculture Organization (FAO).
Granular synthesis possible. Greek composer Iannis Xenakis is known as the inventor of the granular synthesis technique. Canadian composer Barry Truax was one of the first to implement real-time versions of this synthesis technique. "Granular synthesis has been implemented in different ways, notably by the Canadian composer Barry Truax." There are now many dedicated devices available for exploring granular synthesis without using a computer. Many of these devices are in the Eurorack modular synthesizer format, such as: Granular synthesis Granular synthesis is a basic sound synthesis method that operates on the microsound time scale. It is based on the same principle as
