Physical modeling synthesis : balance between realism and computing speed

International audiencePhysical modeling sound synthesis methods are known to be on the one hand potentially interesting in term of sound richness and probability, but on the other hand expansive to develop and compute. This paper is dedicated to mass-interaction methods using explicit time. By studying theoretically a specific model, we define a new basic modelization toolkit using non-linear stiffness and we show how it is possible to reach a balance between computing speed and sound realism.Physical modeling sound synthesis methods are known to be on the one hand potentially interesting in term of sound richness and probability, but on the other hand expansive to develop and compute.
