Excitations models in self-sustained oscillators with a focus on the bowed string

Stefania Serafin $<$serafin at ccrma$>$ (Music)

Talk 1:

The goal of this talk is to analyze different kinds of excitation models with a focus on friction-driven self-sustained oscillators like the bowed string. Different kinds of models have been proposed to reproduce the action of a bow exciting a violin string. Nowadays the availability of fast processors allows implemention of highly refined models in real-time. In this talk, I will present the evolution of friction models from the very simple one proposed by Coulomb to the latest discoveries on bowed string modeling.

Talk 2: Randal Leistikow will present his latest results constructing a "piano filter bank" which sets a passband around each piano key and rejects all other keys.
